This is the most commonly used method for finding your exact tennis racquet grip size: On your dominant hand, note that your palm has three main creases. Hold your hand flat, with the fingers alongside one another. Measure from the middle crease of your palm, up the line between your middle and ring fingers, to a point equal to the height of the tip of your ring finger. Your grip size is that distance.
If you don’t have a ruler handy you can also use your height and this chart to get a good grasp of what range your grip size is in:
Height |
Grip Size |
Under 5'2" |
4 1/8 |
5'3" to 5'5" |
4 1/4 |
5'6" to 5'8" |
4 3/8 |
5'9" to 5'11" |
4 1/2 |
6'" and taller |
4 5/8 |
The average grip size is generally around 4 3/8 inches, and you can always easily increase the size of a slightly smaller grip with the use of over grips.
