A racket that feels right in the shop can become a distraction by the second set. If the handle is too small, you may grip it too tightly and lose stability. Too large, and quick wrist movement becomes harder work. This racket grip size guide helps you find a handle that supports control, comfort and confidence whether you play tennis, badminton or squash.
Grip sizing is not about finding one magic number. Your hand size matters, but so do your playing style, the racket sport, your preferred grip setup and whether you use an overgrip. The aim is simple: choose a handle you can hold securely without straining your hand or limiting your strokes.
Why racket grip size matters
Your grip is the point of contact for every serve, clear, drive, volley and backhand. A well-sized handle lets the racket move naturally through the hand while staying stable at impact. It also makes it easier to change grips between shots, which matters when the pace lifts.
A handle that is too small can make the racket twist on off-centre strikes. Many players respond by squeezing harder, which can tire the forearm and contribute to discomfort around the wrist or elbow. A grip that is too large can reduce feel and make it more difficult to use the fingers and wrist freely, particularly for touch shots and fast defensive reactions.
There is a trade-off. Some powerful players like a slightly fuller handle for a planted, secure feeling. Players who rely on quick wrist action often favour a marginally smaller starting grip with an overgrip added later. Comfort during real play should always beat a number on a chart.
Racket grip size guide: measure your hand first
The most useful starting point is a simple hand measurement. Hold your dominant hand open with the fingers together. Measure from the tip of your ring finger down to the middle crease in your palm, where the hand meets the fingers. This measurement gives a good indication of the tennis grip size to try.
Tennis grips are commonly measured in inches and millimetres. Adult sizes usually run from 4 inches to 4 5/8 inches, with each step increasing by 1/8 inch. In European labels, you may also see L0 to L5, and occasionally larger. As a general guide:
- L0 is 4 inches or roughly 102mm
- L1 is 4 1/8 inches or roughly 105mm
- L2 is 4 1/4 inches or roughly 108mm
- L3 is 4 3/8 inches or roughly 111mm
- L4 is 4 1/2 inches or roughly 114mm
- L5 is 4 5/8 inches or roughly 118mm
Use the index-finger test
Once you have a racket in hand, take a standard forehand grip. Slide the index finger of your free hand into the gap between the fingertips and palm of the hand holding the racket.
If the finger fits snugly, the grip is generally in the right range. If there is no room, the handle may be too small. If there is a large gap, it is likely too big. This test is quick and practical, but it is not absolute. If you are between sizes, hit with both where possible. A few minutes of serving, forehands and backhands will tell you more than a measurement alone.
Tennis, badminton and squash grips are not labelled the same
Do not assume that an L3 tennis racket has anything in common with a G3 badminton racket. Each sport, and sometimes each brand, uses its own grip labels.
Tennis racket grip sizes
Tennis uses the most familiar L0 to L5 system. The handle is usually a shaped octagon, helping players identify the bevels for forehand, backhand and serve grips. Because tennis rackets are relatively heavy and produce high impact forces, handle stability is a major consideration.
If you are unsure between two tennis sizes, choosing the smaller option is often the more flexible choice. It is easy to increase the circumference with an overgrip or a heat-shrink sleeve fitted professionally. Reducing an oversized handle is much more difficult and can change the racket’s balance or structure.
Badminton racket grip sizes
Badminton grips are commonly marked G5, G4 or G3. In many ranges, the higher G number indicates a smaller grip, but always check the manufacturer’s specification as conventions can vary.
Badminton players frequently customise the handle with a replacement grip and one or more overgrips. This makes the label on the cone less decisive than it is in tennis. A smaller base handle can be useful because it leaves room to build the grip to your preference. The right finished size should allow relaxed finger control for quick changes between forehand, backhand and net play.
Avoid building a badminton grip too thick simply for softness. A heavily padded handle can dull the feedback needed for delicate net shots and rapid racket preparation. If sweat is the issue, a tacky or absorbent overgrip may solve the problem without adding excessive bulk.
Squash racket grip sizes
Squash rackets tend to come in a more standard, compact handle size than tennis rackets. Manufacturers may use their own descriptions rather than a universal L-size label. As squash rewards rapid wrist movement, deception and short preparation, players often prefer a grip that feels secure but not bulky.
The factory grip is a sensible place to begin. Add one thin overgrip if you want more cushioning or traction, then assess how the racket feels during drives, volleys and work around the T. If your hand feels locked in place or slow to adjust, remove some thickness before changing rackets.
Account for replacement grips and overgrips
A new racket’s stated grip size describes the bare handle with its factory grip. What you add after that changes the result. A replacement grip is the thicker base layer, while an overgrip is a thinner layer wrapped over it for tack, absorption and extra comfort.
One overgrip can make a noticeable difference, especially on a smaller badminton or squash handle. Two overgrips, a thick cushioned grip, or a generous overlap while wrapping can take a handle up far more than expected. This is why it makes sense to decide how you normally set up a racket before choosing the base size.
Players in busy training blocks should replace worn grips regularly. A grip that has become smooth, hard or slippery encourages a tighter hold, even if the underlying size is correct. In damp halls, hot weather or long matches, an absorbent overgrip can make more difference to control than changing racket model.
Signs your racket handle needs attention
Your hand should not have to fight the handle. If you regularly get blisters in the same place, forearm fatigue, finger cramping or a feeling that the racket turns in your hand, check your grip setup before blaming your technique.
A too-small grip often feels unstable and encourages squeezing. A too-large grip can leave you struggling to wrap the fingers naturally around the handle, especially when changing to a backhand grip. However, discomfort can also come from poor technique, a grip wrapped badly, an overly stiff racket or a sudden increase in playing volume. Consider the full picture.
Choosing a grip size for children and juniors
For younger players, a comfortable, manageable racket is more valuable than buying extra size for growth. An oversized handle can make it difficult for a child to learn correct grip changes and develop a relaxed swing. Junior rackets are designed with age, height and length in mind, so use the recommended racket length first and then check that the handle sits naturally in the hand.
If a junior player is moving towards a full-size racket, start conservatively with grip size. A thin overgrip can add a little comfort as needed. Parents should also check that the grip is not worn smooth, particularly on rackets passed down between siblings or club players.
Make the final choice on court
Measurements and labels narrow the options, but play decides the answer. Hold the racket with the grip you would genuinely use, including any overgrip. Make a few shadow swings, switch between forehand and backhand, and notice whether you can keep your hand relaxed.
The best handle size is the one that lets you focus on the shuttlecock or ball rather than your hand. Start with a sensible base size, make small adjustments instead of drastic changes, and give yourself a session or two to judge the feel properly. A fresh grip and a properly fitted handle are small details that can make every shot feel more assured.
