Selecting The Appropriate 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.
Measure Your Hand
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 and creases running through your palm.
You’ll see two larger lines in the middle of your palm, one on top and one on the bottom, running horizontally from one side to side.
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 top 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. If you do order online and you’re between sizes, then 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.
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 and note the size of the grip. 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 matches up, I’d recommend trying one size above and below to compare and see what feels best. The racquet should feel comfortable yet secure.
Many players will fall between sizes. 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, the addition of 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.
