Quick answer: In the UK, tennis grip sizes run from L0 (smallest) to L5 (largest). To find yours, measure from the middle crease of your palm to the tip of your ring finger in millimetres, or use the finger test: hold the racket and check you can fit your index finger in the gap between your fingers and palm. When in doubt, size down, as you can always build a grip up.
Grip size is the detail most players never think about, yet it affects comfort, control and even injury risk. Get it wrong and you'll grip too tightly, tire your forearm and lose feel. Get it right and the racket disappears into your hand. Here's how to choose properly.
UK grip sizes explained
British and European rackets use an L-number system. The bigger the number, the bigger the handle circumference.
| UK size | Common label | Typical suit |
|---|---|---|
| L0 | 4 (0) | Juniors, small hands |
| L1 | 4 1/8 | Smaller adult hands |
| L2 | 4 1/4 | Many women, smaller men |
| L3 | 4 3/8 | Many men, larger hands |
| L4 | 4 1/2 | Large hands |
| L5 | 4 5/8 | Very large hands |
L2 and L3 are the most popular adult sizes by a distance. Junior rackets are sized differently by length, so grip size matters most once you're into full-size adult frames.
How to measure your grip size
There are two reliable methods. Do both if you can, and cross-check.
Method 1: the ruler measurement
Open your playing hand flat. Measure from the middle horizontal crease of your palm up to the tip of your ring finger. That distance in millimetres corresponds closely to your grip size. Most adults land between roughly 108mm and 118mm, which maps onto L2 to L4.
Method 2: the finger test
Hold the racket in a normal forehand grip. Slide the index finger of your other hand into the gap between your fingertips and the base of your palm. You should be able to fit one index finger snugly. If there's no room, the grip is too small. If there's loads of space, it's too big.
Why the right grip size matters
- Too small: you'll grip harder to stop the racket twisting, which fatigues the forearm and can contribute to tennis elbow.
- Too big: you can't manoeuvre the racket freely, wrist action is restricted, and it's harder to change grips quickly at the net.
- Just right: relaxed hold, better control, less strain and easier grip changes.
When in doubt, size down
Here's the specialist's trick: it's easy to make a grip bigger, but you can't make it smaller. Adding an overgrip increases the size by roughly half a grip size, and a replacement grip or heat-shrink sleeve can add more. So if you're between two sizes, choose the smaller one and build it up to taste.
Remember that overgrips also add cushioning and absorb sweat, so factor one in when you're judging the fit.
Grip size and your wider setup
Grip size is one piece of the racket puzzle. Once it feels right, make sure the frame itself suits your game with our how to choose a tennis racket guide, and check the head size and weight guide so the whole racket works for you.
FAQs
What is the most common tennis grip size?
For adults, L2 (4 1/4) and L3 (4 3/8) are by far the most common. L2 suits many women and smaller-handed men, while L3 suits many men and larger hands.
Should I size up or down if I'm between sizes?
Size down. You can always add an overgrip or replacement grip to build the handle up by around half a size, but you can't shrink a grip that's too big.
Does an overgrip change my grip size?
Yes. A single overgrip typically adds around half a grip size and a bit of cushioning. Bear that in mind when measuring, especially if you always play with one on.
Can the wrong grip size cause tennis elbow?
It can contribute. A grip that's too small makes you squeeze harder to stop the racket twisting, increasing forearm strain. Correct grip size, along with the right string setup, helps reduce that load.
