Tennis racket grip size guide.
How grip size affects your game, and how to find the size that fits your hand.
Why grip size matters
Playing with the wrong grip size can affect comfort, control, and even injury risk. A grip that's too small forces your hand to squeeze harder to keep the racket stable, which can lead to fatigue and strain over time.
A grip that's too large limits wrist snap and makes it harder to change grips quickly between shots, which can cost you precision on volleys and serves.
How grip sizes are measured
US grip sizes run from 4" to 4 5/8" in eighth-inch increments — commonly labeled 4, 4 1/8, 4 1/4, 4 3/8, 4 1/2, and 4 5/8 — measured as the circumference of the handle.
Some brands use European sizing (0–5) instead, which maps to the same range of physical grip sizes.
How to find your grip size
A simple way to estimate your grip size is to measure from the middle crease of your palm to the tip of your ring finger — that length in inches is roughly your ideal grip circumference.
You can also hold the racket with a normal forehand grip and check the space between your fingertips and the base of your palm. About a finger's width of space is a good fit.
Signs your grip doesn't fit
If your grip is too small, the racket tends to twist in your hand on off-center hits, and your fingers may dig into your palm during play.
If your grip is too large, your wrist feels restricted, changing grips between shots gets harder, and your hand can tire quickly from over-gripping to compensate.
Adjusting with an overgrip
Overgrips add a small amount to a racket's grip size and let you fine-tune the fit without buying a different racket. Most players can size up roughly half a grip size with a single overgrip layer.
This makes it easier to size down slightly when choosing a racket and adjust up from there, rather than starting with a grip that's too large.
