How to Determine Your Grip Size
There are two common methods used to help identify the ideal grip size for a player. I typically recommend using both to help get the best fit.
However, before getting started, keep in mind that these methods intend to get you in the right ballpark for your grip size.
Unfortunately, both methods are imperfect, but they should help get you close to the correct measurement, which you can refine by testing different grip sizes in person to achieve the optimal fit.
How to Measure Your Grip Size
First, if you have one handy, grab a ruler or measuring tape. Next, take a look at your dominant hand, and you’ll notice you have a bunch of lines or creases running through your palm.
If you look closely, you should see two large or more prominent lines in the middle of your palm, one on top and one on the bottom, running horizontally from one side to the other.
Grab your ruler or measuring tape and line it up vertically with your ring finger so that the bottom of the ruler lines up with the top horizontal line in your palm and measure to the tip of your ring finger.
You should find that the measurement falls somewhere between 4 inches and 4 3/4 inches. As you can see above, mine measures 4 3/8 inches or a size three grip.
This method works great if you’re ordering online and you don’t have access to test out multiple grip sizes in person. However, if you do order online and you’re between sizes, I’d encourage you to go with the smaller size as it’s much easier to increase the size of a grip than decrease it.
Please keep in mind that the creases in everyone’s hands aren’t identical and vary from one person to the next. With that in mind, if the lines in your hand don’t look like mine, then that’s fine. Most likely, you have at least one prominent crease that runs close to the edge of your hand, which should be sufficient for taking a measurement.
Test Grips in Person
Another method you can use to find the right grip size is to try out multiple sizes in person and reference the gap between your fingers and your palm when holding the racquet.
First, grab a racquet handle with your dominant hand and note the size of the grip. Then, with your other hand, place your index finger within the gap between your fingers and your palm. You’re looking for a grip where that space is roughly equal to your index finger’s width.
Once you find the grip size that roughly matches up, I’d recommend trying one size above and below to compare and see what feels best. The racquet’s handle should feel comfortable yet secure.
Many players will fall between sizes, which is common. If that’s you, I’d encourage you to go for the smaller size because it’s easier to increase your grip’s size than it is to decrease it.
For example, adding an inexpensive overgrip will increase the size of your grip by 1/16 of an inch or a half size. Similarly, you can have a local racquet technician add a heat shrink sleeve to the grip to increase the size by 1/8 of an inch for a full-size increase.
However, apart from swapping out the base grip that came with the racquet or removing it altogether, it is difficult and, in some cases, not possible to drop the size of a grip.
Men’s vs. Women’s Grip Sizes
Tennis racquet grip sizes are universal, not gender-specific.
Although it’s common for women’s hands to be smaller than men’s, the sizes or measurements don’t change for genders.
Average or Most Common Size Grip
A size 3 or 4 3/8 grip is the most common, and you’ll find a lot of crossover between men and women at this size.
The vast majority of women will play with a grip size that’s a size 1, 2, or 3. Men, on the other hand, will typically have a size 3, 4, or 5.
Although average or standard grip sizes are helpful as a point of reference, many players fall outside these ranges, so it pays to do your homework.
4 3/8 vs. 4 1/2 Grip Sizes
Many men looking for tennis racquets will find themselves choosing between a size 3 (4 3/8 in) and size 4 (4 1/2 in) grip.
If you’re on the fence between the two, I’d encourage you to go with 4 3/8 because it’s much easier to build up a grip than reduce it and the difference between the two is only 1/8 inch or 3.2 mm.
You may also find that adding a single overgrip to a size 4 3/8 grip for a half size or 1/16 inch increase gives you the perfect fit as it does for me.
