Tennis grip size calculator
Measure your hand with a ruler, type in the number, and get your grip size.
How to measure
- Open your playing hand flat with the fingers together.
- Find the middle crease of your palm, the lower of the two long lines that run across it.
- Line a ruler up with your ring finger and measure from that crease to the tip of the ring finger.
Most adults land between 4 and 4 5/8 inches (about 102 to 117 mm).
Grip size chart
| US size (inches) | European size | Millimetres |
|---|---|---|
| 4 | 0 | 102 mm |
| 4 1/8 | 1 | 105 mm |
| 4 1/4 | 2 | 108 mm |
| 4 3/8 | 3 | 111 mm |
| 4 1/2 | 4 | 114 mm |
| 4 5/8 | 5 | 117 mm |
European sizes are often written with an L in front, so L2 is the same as 4 1/4.
Between two sizes?
Pick the smaller one. You can always make a grip bigger: an overgrip adds roughly 1/16 of an inch, which is half a size. Making a grip smaller is much harder.
Check it in your hand
Hold the racket in a normal forehand grip. You should be able to fit the index finger of your other hand snugly in the gap between your fingertips and the base of your thumb. No room means the grip is too small; a loose gap means it is too big.
A grip that is too small makes you squeeze harder and can twist in your hand. One that is too big is tiring to hold and restricts your wrist. Either can irritate your elbow over time.
