Hey there, tennis friends.
Let’s talk about something that might seem small but makes a big difference: grip size. If you’ve ever felt like your racket was slipping out of your hand or you’re getting blisters and don’t know why, chances are you’re using the wrong grip size.
As a coach, I’ve seen this happen more often than you’d think. Parents bring in their kids with shiny new rackets that look great, but when they swing, something feels off. Adults face the same issue. Either the grip is too big, making their hand feel like it’s wrapped around a baseball bat, or it’s too small, so they’re choking the handle just to feel secure.
Let’s break it down plainly: here’s how to pick the right grip size for a tennis racket, based on the age of the player and the size of the racket. Once you get this part right, the whole game feels a lot smoother.
And of course, remember that each player is different. For example my son is 9 years old and he has been using a 27″ racket with a size 1 grip for a few months and he can hit way much better than when he was using a smaller racket, so I would recommend trying different options at your local tennis shop.
What Is Grip Size, Anyway?
Grip size refers to the circumference of the handle of your racket. In the UK and Europe, it’s usually measured using the L0 to L5 scale:
- L0 = 4 inches (102 mm)
- L1 = 4 1/8″ (105 mm)
- L2 = 4 1/4″ (108 mm)
- L3 = 4 3/8″ (111 mm)
- L4 = 4 1/2″ (114 mm)
- L5 = 4 5/8″ (118 mm)
Here in the UK, Junior rackets typically come in L0 or smaller. Adult rackets range from L1 to L5.
Why does grip size matter? Because it affects your comfort, control, and even your health. The wrong size can lead to poor shots, reduced power, and even wrist, elbow, or shoulder injuries—like the dreaded tennis elbow.
How to Measure Grip Size
Here’s a quick and easy test you can do at home:
The Ruler Test
- Open your hand flat and measure from the tip of your ring finger to the bottom lateral crease of your palm.
- That number, in mm or inches, corresponds to the ideal grip size (refer to the L-scale above).
The Finger Test (if you already have a racket)
- Hold the racket like you’re shaking hands with it.
- Slide the index finger of your other hand between your ring finger and the palm holding the racket.
- If it fits snugly, you’re golden. If there’s too much space, the grip is too big. If you can’t squeeze your finger in, it’s too small.
For Kids (Ages 4–12): Go Small and Light
Kids’ hands are small, and their muscles are still developing. So, their rackets need to match that. Most junior rackets come with grip sizes of L0 or smaller, which usually works well.
| Age | Racket Length | Typical Grip Size |
|---|---|---|
| 4–6 | 19″–21″ | L00 – L0 |
| 7–8 | 23″–25″ | L0 |
| 9–10 | 25″–26″ | L0 – L1 |
| 11–12 | 26″–27″ | L1 – L2 |
Tip from Coach: Don’t stress too much about exact sizes for kids. Go with what feels most natural. If their fingers wrap too far around the grip or they struggle to hold it securely, you likely need to adjust.
For Teens (Ages 13–17): Stepping Into Adult Sizes
By the teenage years, most players are ready for full-size (27″) rackets and will begin using adult grip sizes, typically L1 to L3.
- Smaller hands (under 165mm palm to fingertip): L1
- Average hands (165mm to 180mm): L2 – L3
- Larger hands (over 180mm): L4 or higher
Coach’s Advice: Teens are still growing, so if they’re between sizes, go smaller—you can always bulk it up later with an overgrip (adds about 1.5mm or 1/16″).
For Adults: Precision Matters More
Adult players generally use grip sizes between L2 and L4, depending on hand size, play style, and comfort preferences. Use this guide:
| Hand Size (Palm to Ring Finger Tip) | Grip Size (UK / EU) |
|---|---|
| < 165 mm | L1 (4 1/8″) |
| 165–180 mm | L2–L3 (4 1/4″ – 4 3/8″) |
| 180–190 mm | L4 (4 1/2″) |
| 190 mm+ | L5 (4 5/8″) |
But don’t just go by the numbers—feel matters too. A slightly smaller grip allows more wrist movement (helpful for topspin), while a slightly larger grip offers more stability and comfort, especially for volleys and one-handed backhands.
What If You’re Between Sizes?
If you’re stuck between two grip sizes—say L2 and L3—choose the smaller one. You can always:
- Add an overgrip (adds ~1.5 mm / 1/16″)
- Use a heat shrink sleeve to increase the grip permanently (~2–3 mm)
It’s much easier to size up than to size down. If a grip is too large, your only fix is to replace the handle or switch rackets—neither are ideal.
Signs You Have the Wrong Grip Size
If you already have a racket but something feels off, here’s what to watch for:
Grip Too Small
- You’re squeezing the handle too tightly for control
- Hand cramps or gets tired quickly
- Too much wrist movement, loss of stability
Grip Too Big
- Hard to generate spin or whip through the ball
- Grip feels clunky or hard to maneuver
- Forearm or elbow soreness after long sessions
Final Thoughts from the Court15 Team
Getting the grip size right isn’t about being technical—it’s about being comfortable, confident, and injury-free. Whether it’s for your first racket or your next upgrade, take a few extra minutes to get the size that feels just right in your hand.
Try a few rackets at your local shop if possible, ask someone experienced, and don’t be afraid to experiment a little. It’ll make a huge difference on court.
