How to measure your tennis racket grip size

Finding the correct grip size ensures better handling and prevents unnecessary strain on your wrist and arm. There are two common methods to determine your ideal grip size:

The ruler test

• Hold your dominant hand open with fingers extended.
• Align a ruler vertically against your ring finger, measuring from the tip to the second crease in your palm.
• The measurement (typically between 4" to 4 ¾") corresponds to standard grip sizes.

The index finger test

• Hold a racket with a standard eastern grip (where the base knuckle of your index finger rests on the third bevel of the handle).
• Place the index finger of your non-dominant hand between your fingertips and the palm side of the grip.
• If there is too much space, the grip is too big; if there’s no space, the grip is too small.

The benefits of overgrips

• Comfort: Adds cushioning and reduces hand fatigue.
• Improved grip and tackiness: Helps maintain a firm hold, especially in humid conditions.
• Customisation: Allows minor grip size increases without needing a different racket handle.
• Hygiene and longevity: Absorbs sweat and dirt, preventing the handle from deteriorating.

When to replace your overgrip

Regularly changing your overgrip ensures maximum performance and comfort. Here are signs it’s time for a replacement:

• Loss of tackiness: If the grip feels slippery or difficult to hold.
• Visible wear and tear: Fraying, discoloration, or thinning of the material.
• Excessive sweat absorption: Overgrips become less effective after prolonged moisture absorption.
• Reduced comfort: A hardened or flattened overgrip can cause blisters and discomfort.
