How to Measure Your Tennis Racket Grip Size?

The proper tennis racket grip size significantly affects the performance of the racket.

A grip size that is too small necessitates greater muscular strength to prevent the racket from twisting in your hand. Prolonged use of an undersized grip can contribute to tennis elbow issues. Conversely, a grip that is too large hinders wrist snap on serves, makes changing grips more challenging, and also requires more muscular strength. Prolonged use of an oversized grip can also contribute to tennis elbow problems.

1. To determine if the grip size is appropriate, hold an eastern forehand grip (the palm is placed against the same bevel as the string face) and check if you can fit the index finger of your non-hitting hand in the space between your ring finger and palm. If there is insufficient room for your index finger, the grip is too small. If there is a gap between your finger and palm, the grip is too large.

2. If you don’t have a racket available, you can also measure your grip size using a ruler. Keep your hand open and fingers extended closely together, align the ruler with the bottom lateral crease of your palm, and measure up to the tip of your ring finger.
