For many players, string tension is an overlooked aspect of their tennis racquet. However, the tension at which a player strings their racquet can significantly impact performance and serve as an excellent fine-tuning mechanism for playing your best tennis.
Gaining an understanding of string tension allows savvy players to identify a tension that feels right to enhance their game and even help with other factors, such as arm injuries and match-day nerves.
Tension is a measure of the force pulled by a stringing machine when installing strings, typically expressed in pounds or kilograms.
When you have your tennis racquet strung or string it yourself, a specific tension is applied to the string by a machine. More accurately referred to as reference tension, this is a measure of weight being applied to the string as it’s pulled, which we can express in kilograms or pounds.
Before a racquet technician installs strings, they’ll set their machine to the client’s desired tension. Then, as they weave the strings through the frame, the machine will pull the string to the appropriate tension.
It’s worth noting that while a machine will pull a string to the pre-determined reference tension, the finished product’s actual tension will differ and typically be slightly lower due to the installation process.
For example, a technician will install the main strings on a racquet first, so there isn’t any friction of the cross strings when pulling the string to the desired tension. However, after installing the main strings, the cross strings must weave through the main strings, which imparts friction and impacts the final or actual tension.
If you’re trying to decide on a tension, there’s no right or wrong answer as it’s a personal preference. However, the information we cover in this guide will help you determine an ideal tension that will ensure you get the most out of your racquet and perform your best on the court.

The following sections will closely mirror the above video outline, but you’ll also find some extra content like pro string tensions that we haven’t included in the video.
Tension Ranges
Most tennis racquets come with a recommended tension range determined by the manufacturer for optimal performance, which serves two purposes.
First, it’s the range the manufacturer has determined the racquet performs its best. However, this range is also important beyond performance because it considers the frame’s strength to ensure it doesn’t break under pressure.
Helpful Tip
The tension you choose to string your racquet is up to you as these are purely recommendations, but it’s worth noting you may void its warranty if your string tension is determined to have caused your racquet to break.
At a high level, the recommended tensions ranges across most racquets will start as low as 18.14 kilograms or 40 pounds and end around 30.84 kilograms or 68 pounds.
However, while this feels like a rather large spread, each racquet’s range will typically span roughly 5 to 15 pounds. Here’s a selection of popular racquets and the recommend tension ranges for reference:
You may also find some of the tennis strings you purchase offer a recommended tension range. For example, Babolat’s RPM Blast recommends 48 – 66 lbs or 22 – 30 kg, a rough guide for understanding where they have determined the string performs its best.
Lower vs. Higher String Tension
When stringing tennis racquets, a common question that surfaces for players is whether they should string with a higher or lower tension and what impact the change will have on their racquet’s performance.
The simple answer is that lower tensions will provide you with more power, while higher tensions will give you more control.
However, there’s a bit more to the equation, and it has to do with stringed stiffness, which tension influences. As we cover this topic, let’s assume all other factors are equal.
Low String Tension
A lower tension will result in more power because of a decrease in the stringbed stiffness, which impacts the trajectory or direction of the ball as it leaves your strings.
It turns out that the flight path of a stiffer stringbed is higher, so the ball flies further and lands deeper in the court without a change in effort.
High String Tension
On the other hand, a higher tension will result in less power because of an increase in stringbed stiffness, which has the opposite impact on the ball’s trajectory as it leaves your strings.
More specifically, the ball’s flight path is lower, so the ball doesn’t fly as far and will land shorter in the court.
What doesn’t change with higher or lower tensions is the speed of the ball as it leaves your strings, which the tennis racquet and speed at which it’s strung impacts, as studies have shown.
Of course, that’s a lot to absorb, so it’s not surprising it’s common to suggest players string lose for power and tight for control, especially considering that’s how most players perceive changes in tension.
String Tension and Topspin
Often players will question which tension is best for topspin.
Unfortunately, to date, it’s not proven definitively through research whether or not higher or lower tensions increase topspin.
As a result, if spin a priority, I encourage players to focus their energy on their technique and racquet head speed, which has the greatest influence, while also considering the type of string they’re using.
Polyester tennis strings have the most significant impact on topspin due to the snapback effect of the string as a ball brushes against them. Furthermore, a lower tension for polyester strings may help improve the ability of a string to snap back and subsequently deliver more spin.
For this reason, many players use lower-powered polys. Not only do they have topspin enhancing qualities, but more importantly, they allow the player to swing harder to increase spin.
String Tension & Durability
Another common and hotly debated question is whether higher or lower tensions increase the durability of a string.
Like topspin, the jury is still out on tension and durability, with many professionals believing that lower tensions allow the strings to move more frequently and saw into each other to cause breakage. Conversely, others believe that higher tensions cause increased friction when the strings move, which leads to strings breaking more quickly.
While there is no definitive answer, our recommendation is to lower your string tension to increase durability. From our experience, strings at higher tensions move plenty, which, combined with increased friction, leads to earlier breakage than lower tensions.
However, like topspin, if you’re searching for durability, our primary recommendation would be to consider other variables. For example, the type of string, along with the string’s gauge or thickness, will have a more tangible impact than modifying tension.
Finding the Right Tension
When you’re stringing a racquet for the first time, it doesn’t have to be a guessing game. First, start with the tension range recommended by the racquet’s manufacturer.
You can typically find these numbers printed directly on the frame – check the inside of your tennis racquet’s throat or the inner edge of the frame’s head as a starting point. Manufacturers will test their racquets with real players to determine an appropriate range.
The best thing you can do the first time around when stringing a new racquet is splitting the difference and starting with a tension right in the middle of the manufacturer’s recommendation.
For example, if your racquet says the recommended string tension is 55 to 60 pounds, start with 58 pounds. Then, based on the racquet’s performance, you can adjust up or down to your preference.
It may take a few attempts to dial in your preferred tension, but if you start in the middle, you should be able to nail it down pretty quickly. If you have more than one racquet, you can have each strung at different tensions to compare them side-by-side.
Helpful Tip
It’s worth noting that there are no rules in tennis that specify acceptable tension ranges. Instead, this is entirely up to the player to determine based on personal preference.
As you work to find the right string tension, we recommend that you stick with the same string as you make adjustments.
Different types of strings can have a dramatically different feel and performance at various tensions. Therefore, it’s best to stick with a single string until you find a tension you enjoy.
If you eventually move to a new string, you may need to adjust to your tension to accommodate the change.
Testing with Two Racquets
If you have two of the same racquet, I’d recommend you string them both fresh at different tensions so you can compare how they feel in real-time.
Of course, if you don’t have two of the same racquets, you can test two different tensions back to back. However, I’d encourage you to restring with the new tension sooner than you might typically restring, i.e., after one or two weeks of hitting with one tension, cut the strings out and switch to the new tension so that you can get the closest possible comparison.
Best String Tension
Many players ask what the best string tension is for their racquet, which is entirely understandable. However, although we can provide general recommendations, what’s best is ultimately player-specific.
Recognizing this, we’d encourage you to use this resource to understand how to think about tension, which you can then use to identify the best tension for your racquet, strings, and desired performance characteristics.
Although it will take a bit of effort upfront to learn the general concepts, you’ll benefit from the knowledge for years to come and be better equipped to adjust tension to fine-tune your racquet.
If you’re looking for more specific tension recommendations, don’t forget to check out our guide toward the end of this article.
Word of Caution
Often, players looking for more control or power will attempt to adjust their string tension to achieve a more pronounced effect. However, while it’s correct that tension will change these variables, there’s a diminishing return on overall performance. As a result, you’ll likely end up with adverse side effects, so it’s worth evaluating other factors.
For instance, a player would benefit from improving their technique, fitness, and selection of string or racquet to substantially increase control or power.
With that said, you should think of string tension as more as a fine-tuning mechanism to get the most out of your racquet, string, and, more importantly, the talent that you’ve developed through practice.
Tension Loss Considerations
After you string your racquet, it will begin to lose tension. In fact, strings can lose up to 10% of their tension within 24 hours.
To prevent this, some players will ask their racquet technicians to pre-stretch their tennis strings. Before installing strings, the stringer gently stretches them manually or uses a pre-stretch feature available on many electronic stringing machines, so they don’t have much initial tension loss.
Furthermore, each type of string loses tension at different rates, and some strings are better at holding their tension. For example, natural gut and multifilament strings tend to do a terrific job maintaining their tension, while polyester strings typically don’t.
As you choose a tennis string, it’s good to be aware of these qualities because they can impact the performance of your racquet and, subsequently, the frequency at which you restring.
String Tension for Varied Conditions
As a player’s skill level improves and they compete at higher levels, string tension becomes more crucial and nuanced.
Beyond finding an ideal tension, players will fine-tune their tension according to the conditions for optimal performance. Typically, this happens during practice leading up to a match where the players will have a good sense of what to expect.
Keep in mind that the tension changes for the following conditions are usually minor, i.e., 1-2 lbs (.5-1 kg).
Temperature
If you live in an area where the seasons are prominent, and the weather changes substantially throughout the year, you’ve likely experienced playing in warm and cool temperatures.
If so, you’ve likely experienced how the ball is a bit more lively during a hot day, while it can feel almost dead on a cold day. To accommodate, some players will adjust their tension up slightly during warmer conditions for more control and decrease tension on cooler days for added power.
Humidity
During warm, dry conditions, a tennis ball will fly through the air with little resistance, which speeds up play. However, higher humidity puts extra drag on the ball and slows down pay. Tennis balls can even hold moisture from the air and sweat from players.
Once again, some players sometimes will increase tension during drier conditions to improve control, while they may decrease tension slightly to increase power. As you’d expect, temperature and humidity go hand in hand. Hence, players have to feel out the conditions to determine how best to adjust tension for the current or expected conditions.
Surface
Each court surface plays slightly different, with grass being the fastest being grass, hard courts falling in the middle of the spectrum, and clay courts playing the slowest.
Once again, players will adjust their tension accordingly. When playing on faster surfaces like grass, players might increase tension for a bit of added control. However, on a slower surface like clay, where the ball also tends to retain a bit of debris, players tend to drop tension a few pounds to increase power a bit.
Altitude or Elevation
Last but not least, altitude can also influence the tension a player selects. At higher elevations, tennis balls are bouncier, hence the reason for high altitude balls. However, players still often feel like the balls have more pop because the air is thinner and the humidity lower.
When a player returns to a lower altitude, they’ll drop their tension back again to accommodate the conditions.
Types of Strings and Tension
Different types of tennis strings feature different materials and construction and, as a result, can exhibit dramatically different feel at the same tension. In other words, a tension that works for one string may be a poor choice for another.
For example, if you were to string your racquet at 60 pounds with a nylon multifilament and then switch to a polyester string and use the same tension, you’d most likely be disappointed in performance because polyesters tend to work better at lower tensions.
Let’s do a quick review of the different types of strings with our favorite picks in each category.
Natural Gut
Some of the most expensive strings on the market, natural gut strings are made from cow intestine and feature excellent power, comfort, and feel. Due to their elasticity, they do a fantastic job maintaining tension and perform exceptionally well at higher tensions.
Frequently, players that move to natural gut from synthetic materials will be inclined to string at slightly higher tensions for more control.
Typically made from nylon, synthetic gut strings are a cost-effective choice for a wide range of players and offer average all-around performance. In addition, synthetic gut strings perform well at various string tensions, depending on player preference.
Multifilament tennis strings seek to replicate the performance of natural gut by weaving thousands of fibers together. As a result, they feature similar characteristics, including power, comfort, and feel.
Multifilaments perform well at mid to upper range tensions, with many players stringing slightly higher due to their higher power.
A popular string in today’s modern game of tennis, polyester tennis strings are stiff, lower-powered, and enhance topspin. Due to their monofilament construction, they also offer excellent durability.
Most players will reduce the tension of polyester strings to increase the snapback effect and comfort while allowing them to swing faster to generate added topspin.
I’ve found roughly a 10% drop when moving from synthetic gut or a multifilament to work well as a starting point. However, you’ll want to continue experimenting after the initial reduction in tension to find out what works best for you.
Although not as popular as they once were, Kevlar strings are highly durable yet offer a very stiff feel. As a result, if you experiment with one of the few Kevlar strings still available, you may want to lower the tension to offset the stiffness.
Typically, when you find Kevlar strings, manufacturers will pair them with a softer string as part of a hybrid setup.
When you combine any two sets of tennis string, one set for the mains and another for the crosses, it’s called a hybrid. Popular hybrids include natural gut or multifilament combined with polyester.
It’s common for players to opt for varying tensions for each of the strings, with the poly typically featuring a slightly lower tension of 2 to 3 kilograms or pounds.
Frequently, players with arm injuries will benefit from reducing the tension of their strings to create a softer, more forgiving string bed. The result will help reduce the stiffness associated with higher tensions, which will ultimately be more forgiving for a player’s arm.
Of course, you’ll have to keep in mind how the tension drop will influence power or the depth of your shot, as we’ve covered, but it’s one avenue you can take for improving comfort.
However, if you suffer from an injury such as tennis elbow, don’t stop at string tension. It can also be worth evaluating your string selection, type of racquet (including its weight), and grip size to achieve the highest comfort level. Moreover, you’ll also want to make sure you restring your racquet more frequently because as comfort-oriented strings go dead, they’ll lose these qualities.
Some of the top strings for comfort are natural gut, like Babolat VS Touch and Wilson Natural Gut mentioned above. However, the higher price and lack of durability tend to price most players out of using them.
The good news is that multifilaments offer comparable and sometimes better comfort, as is the case with Prince Premier Touch. Both Wilson NXT and Tecnifibre X-One Biphase covered in the previous section are also two great options.
Stringing Multiple Racquets at Various Tensions
It’s common for players who compete at higher levels to carry three or more racquets with at least one racquet strung at a higher tension. While this may seem like a luxury to a casual player, there’s sound logic.
First, if you break a string, you want to have at least one additional backup at the same tension to continue play. However, many players will keep one or more racquets strung a few kilograms or pounds tighter for added control. Some of the pros carry upwards of ten freshly strung tennis racquets with them to every match.
In competitive situations, players will often overhit. The excitement of the match, nerves, and determination to win can make players tighten up or get overly excited and subsequently miss their shots by a small margin.
In this case, it can be beneficial to have a racquet strung tighter to regain control. When you’re hitting a few feet long or wide, a minor change in tension can be the difference a player needs.
String Tension and the Pros
Despite string tension being highly personalized, many players are keen to learn how the pros string their frames.
To that end, here’s a selection of players that draw a lot of curiosity. A few things to keep in mind when reviewing these:
Most pros will vary their tension slightly based on the conditions, i.e., a dry vs. humid climate or higher vs. lower altitudes.
Similarly, while pro model racquets, like Federer’s Wilson Pro Staff RF97, are available for purchase, they will feature additional customizations that cater to their game for optimal performance and ultimately influence the tension they string their racquet.

String Tension Tools
Two common tools to help with string tension measurement are calibrators and tension test tools.
Tension Calibrators
Tension calibrators are simple spring-loaded devices that help racquet technicians ensure their machine is pulling tension accurately.
A stringing technician clamps one end of the calibrator to the machine and then pulls tension, which provides a reading for comparison to the machine’s tension setting.
Depending on the difference reported by the calibrator and the machine’s settings, a stringer can dial in their stringer.
Tension Testers
Players may want to use a tension tester to measure tension loss over time and help determine when it’s time to restring.
You simply measure the tension of your strings as soon as possible after stringing and then continue measuring it periodically until the frame has lost roughly 10-15 pounds of tension.
Helpful Tip
The 10-15 pound threshold can be adjusted based on your preference after using a tension tester for a while.
It’s worth noting that the tension shown by your tester will not match the reference tension you asked your stringer to use as a racquet’s final tension will always differ.
Tension testers aren’t highly accurate devices. Instead, they help gauge relative tension over time as a reference point to determine when to restring.
Here’s a selection of popular tension calibration and testing tools you might want to check out.
Hopefully, the information contained in this resource has helped lay a foundation for better understanding tennis string tension while guiding you to select a tension confidently for your racquet.
With that said, we recognize the information we’ve covered can be overwhelming, so in this section, we’ve provided generalized recommendations you can use as a starting point based on the type of string you’re using, your experience level, and performance goals.
Tension By Type of String
One thing you’ll notice is softer strings, including natural gut and nylon synthetic gut, and multifilaments have higher tension ranges. In comparison, stiffer strings like polyester and kevlar are lower to improve comfort.
Type of String
Tension Range
Natural Gut
50-65 lbs (22.7-27.2 kg)
Synthetic Gut
50-60 lbs (22.7-27.2 kg)
Multifilament
50-60 lbs (22.7-27.2 kg)
Polyester
35-55 lbs (15.9-24.9 kg)
Kevlar
40-55 lbs (18.1-24.9 kg)
Hybrid
45-55 lbs (20.4-24.9 kg)
Don’t forget that the type of string you choose also influences power, i.e., a multifilament strung at the same tension as polyester will offer more power.
Tension by Performance Characteristic
As a general rule of thumb, we recommend players string loose for power and tight for control. Below, you’ll find we’ve broken apart the broader tension ranges to align with these performance characteristics.
Type of String

Tension for Power by Skill Level
As a player’s skill level and ability to produce racquet head speed increases, their ability to generate power on their own will improve.
With this in mind, you’ll notice tensions for power are lower for beginners who can use the extra pace and higher for advanced players who tend to generate velocity on their own.

Tension for Control by Skill Level
As a player’s skill level improves, their technique and gear will generally allow them to handle higher tensions for added control better.
Beginners will also benefit from higher tension for enhancing control but should avoid stringing too tight to prevent a reduction in comfort.

Wrapping Up
Often overlooked, tennis string tension can be a powerful tool for the savvy tennis player and wreak havoc on the game of players who aren’t paying attention to their strings.
Take control of your string tension to maximize your performance and gain an edge over a less prepared player.
Have questions about string tension? Feel free to add your comments below. We’ll be happy to answer any questions you may have!
That’s awesome to hear! Nothing beats having your own stringer, you’re going to have a ton of fun with it :)
If you don’t mind me asking, which stringer did you order?
One of my favorites… stringing, watching tennis on TV and drinking a nice cold beverage. Can’t beat it. I’m glad you found some of the information helpful and would love to hear how things work out with the new machine.
Hi
I found your article very useful. My son who is 14, years old plays with 57 lbs tension 300 GMs rpm blast strings on babolat pure drive French open….now he wants to switch to another racquet.. He plays flat and is in between intermediate to advanced player. Any suggestions on which other racquet and what strings? Thanks in advance

Hi,
I am extremely sorry for not looking up for your reply.
1 His current babolat aero drive is 305 GMs….he is finding it a bit heavy. He tried a Wilson blade and pro staff and found it much more comfortable than babolat.
He wants to have more control than what babolat gives. The strings are pro hurricane tension 60. He is looking for a light weight racquet with more control. His game is predominantly baseline, but does play good game even at the net. The strings do feel dead after just a day of being strung. He liked the feel of Wilson but is unable to choose. Once he played with a head light weight and felt good about it too. His current babolat racquet is kind of heavy for his age and is looking to switch for more control. I hope I answered your qs.
Pl guide me . I ll keep checking your site more often now.
Thanks
Pallavi
Thanks for getting back to me! I’d love to provide you with a more detailed comparison of the tennis racquets that your son has been using as well as some suggestions for new racquets he might want to try.
To help with this could you please provide links to the exact versions of the following tennis racquets that your son has used:
Babolat Aero Drive
Wilson Blade
Wilson Pro Staff
Each of these racquets have different variations with unique specifications, so in order to provide you with the best information it would be helpful for you to tell me the exact racquets your son has used.
Just head on over to your favorite online retailer and then include the links to the racquets in your reply.
sir, i need job. And i want to try other company. I am a racquet stringer here in dubai. Do you know where i can find good company and i can use my work experience here. Im have 6yrs work experience as a racquet stringer.. Please help me..thank you..
I’m don’t personally know a club or company that I can recommend. Unfortunately, I haven’t had the pleasure of visiting Dubai and getting to know some of the locals.
However, it would likely be worth trying a few searches online to see if you can come up with an opportunity for yourself – here are a few ideas to help get you started:
– tennis club
– tennis company
– tennis academy
Hopefully, if you check a few of these out, they’d turn up something for you. Best of luck in your search – let me know if I can help with anything else.
Hi, I am 15 years old, I weigh around 60kg, skinny build, I just purchased an RF97 signature racquet, I actually don’t find the racquet that heavy as is does al the work for me haha, the strings on it feel ok, but I’m looking for slightly more power in the strings, as I play with some hard hitters..,so I’m guessing I’ll have to go lower tension? Do the strings with lower tension go tighter or looser? I once here’d that tighter strings have more power, but I could be wrong,
I might also add, that this racquet had loads of power.. But when balls come flying at you, FAST.. I’m in trouble haha, I’m a wear that it could be my strength, but if I could get different tension or strings and hit or return back hard serves/shots, I’ll be a happy person :) thanks again !
Thanks for stopping by and for the great question.
All things considered equal, lower tension will yield higher power but don’t forget along with that comes less control, so it’s usually a tradeoff. On the other hand, higher tension will produce less power and more control. If you’re looking for a bit more pop, then you can definitely play with adjusting the tension. However, another option would be to consider a different type of string. For example, multifilament strings tend to deliver higher end power so if you play with an inexpensive natural gut or polys then it may be worth investigating.
If you’d like, I’d be happy to make some recommendations. Just let me know what type of strings you’re currently using.
Hi,
I am purchasing a new racket wilson juice blx 100…can you tell me the best optimal tension of that raquet. Tension are from 53-63 lbs..I AM A HARD HITTER AND ULTIMATE smasher and a fair backhand
Hi there! Thanks for your stopping by and for sharing your question. You are correct, the recommended string tension for the Wilson BLX Juice 100 is from 53-63 lbs, however when it comes to which tension you should use it all comes back to personal preference. For example, you described yourself as a hard hitter. If that’s the case I’d be curious to learn whether or not you’re looking to reign in and control your power or if you really enjoy hitting hard and want to maintain as much power as possible.
If you were looking for more control I might suggest you try a tension at the upper end of the recommended stringing tension such as 61-63 lbs. Of course, if you enjoy the power and don’t have a problem with controlling the ball then you might look at stringing the racquet at the lower end of the recommended tension, perhaps 55-57.
The key is to have an initial goal in mind with your string tension and then try a tension that you’d expect to match your needs and adjust from there. It definitely takes some trial and error to find an ideal tension. Here’s a little chart for how I would look at the recommended string tension for your tennis racquet:
Great video! I play with a 2nd gen Pure Strike 98 16×19 and love the racket. I had it strung with Luxilon Element at mid-point tension. I find it comfortable and have no issues/concerns. I am considering buying a 2nd racket (as a backup and to have an extra one) and considering the 3rd gen Pure Strike 98 16×19. I was trying the demo and it came with Head Velocity and I found that my backhands are going deeper (good) but my forehands are going long (bad). This makes sense as this is a multifilament string with more power even though both rackets are similar in terms of weight etc. I am now ready to purchase the 3rd gen Pure Strike but a little confused about the string choice. I am leaning towards choosing same string i.e., Element but lower tension to compare? My style of play is top spin forehand, prefers to come to the net (although I am not a great volleyer) and two-handed backhand. Thanks for any suggestions.
Thanks for your feedback and for taking the time to ask a question.
Since you enjoy your current string, my recommendation would be to stick with Luxilon Element as your first string for the new Babolat Pure Strike you’re planning to buy.
There’s no doubt that the latest generation will feel different, but maintaining the same tension from the 2nd generation to the 3rd generation will allow you to better identify differences in feel, which you can then use to inform your decision to change the tension, keep it the same, or possibly even consider a new string altogether.
I have just ordered my first stringing machine. This article has provided some useful information. Thanks, Rick Lucas

Isn’t Control and Power reversed on your chart?
Whoops! Thanks for the catch, Ron. Just updated.
~ All the best, Jon
I think Control and Power are wrongly placed in above chart.
Hi there Mrugesh! Looks like you and Ron both have a great eye :) Thanks for mentioning. I just updated the chart in one of my previous comments.
