Every summer in Sarasota, a parent walks up to me at Potter Park holding a racquet still wrapped in plastic and asks the same honest question: “Did I buy the right one?” It’s a fair thing to worry about. Junior racquets come in eight or nine different lengths, the weights all sound the same, and the packaging is covered in marketing words that don’t tell you much. I’m Michael Boothman, and after 30-plus years coaching juniors here, I can tell you the racquet matters less than the salesperson wants you to believe and more than most parents assume. Get the size roughly right and your child can learn. Get it badly wrong and you’ve handed them a tool that fights them on every swing.
This guide is meant to save you the guesswork. No brand names, no “best racquet of the year” lists. Just the handful of things that actually change whether your kid can hit the ball cleanly.
Start with length, not brand
Length is the one measurement that matters most for a young player, and it’s the easiest to get wrong because kids grow so fast. Junior racquets run from about 19 inches up to 26 inches, and then adult frames start at 27 inches. The rule I use on the court is simple: have your child stand up straight, arm hanging at their side, and hold the racquet so the head points at the floor. The end of the frame should sit right around the floor or an inch above it. If the racquet is dragging on the ground, it’s too long. If it stops well above their ankle, it’s too short.
As a rough starting point by age: kids around 5–6 usually fit a 21–23 inch frame, 7–8 year olds a 23–25 inch, 9–10 year olds a 25–26 inch, and by 11 or so many are ready for a 26-inch or a light 27-inch adult frame. But treat age as a hint, not a rule. I’ve had tall eight-year-olds on 26-inch frames and small ten-year-olds who hit far better on a 25. The floor test beats the birthday every time. The USTA publishes a clear junior sizing reference that lines up with this, and it’s worth a two-minute read: USTA coaching resources.
Why the right length protects clean contact
Here’s the part that connects to how we actually teach. One of our Six Pillars at SRQ Tennis is Technique Is Geometry — the idea that a good shot comes from center contact and a square racquet face, not from a feeling or a fancy motion. When a racquet is too long or too heavy for a child, they can’t control where the strings meet the ball. The frame drops late, the tip lags, and contact drifts off-center. The kid isn’t doing anything wrong; the equipment is making clean geometry physically impossible.
A properly sized racquet lets a young player get the sweet spot to the ball repeatedly, and that repetition is what builds a real swing. When I see a junior shanking ball after ball, the first thing I check isn’t their form — it’s whether they’re swinging a racquet built for someone twice their size. Fix the tool and half the “technique problems” disappear on their own.
Weight and grip: keep both on the light side
For weight, lighter is almost always better for developing players. A racquet a child can swing freely with a relaxed arm will teach a better motion than a heavier frame they have to muscle around. If your kid finishes a rally shaking out their wrist or dropping the racquet head, it’s too heavy. You want them swinging with ease, not survival.
Grip size trips up a lot of parents, so here’s a quick check that doesn’t require a chart. Have your child hold the racquet in a normal forehand grip, then slide the index finger of their other hand into the gap between their fingertips and the base of their palm. One finger should fit snugly. No gap means the grip is too small; more than a finger means it’s too big. For most juniors, err slightly small — a grip that’s a touch small is easy to build up with an overgrip, while one that’s too big is hard to fix and encourages a death-grip that kills wrist freedom.
What not to overthink
Parents often ask me about string tension, head size, and material. For a junior who is still learning to rally, these are rounding errors. A slightly larger head gives a more forgiving sweet spot, which is genuinely helpful for beginners, so that’s the one small edge worth taking. Beyond that, don’t spend an extra hundred dollars chasing a spec sheet. I’d rather see a family put that money toward court time, because reps on a live ball do far more for a ten-year-old than a premium frame ever will.
And please don’t buy three sizes up “so they can grow into it.” A racquet your child grows into is a racquet they can’t hit with today, and today is when they’re building the habits that stick. Buy for who they are now. When they outgrow it in a year, that’s a good problem — it means they’re getting bigger and better.
A simple decision for a Sarasota summer
If you’re standing in a store this week trying to get a racquet ready for camp or a summer group, here’s the whole thing in three steps. Do the floor test to pick the length. Do the one-finger test to pick the grip, leaning slightly small. Choose the lighter of two options they can both swing. That’s it. You don’t need to be a stringing expert to get this right — you need a child who can make clean contact and enjoy the game enough to come back tomorrow.
If you want a second opinion before your junior starts a summer program, bring the racquet to the first session and I’ll check it in about ten seconds. It’s a small thing, but a racquet that fits is one of the quietest, most underrated ways to help a kid fall in love with tennis. You can read more about how we approach junior development on our coaching page, and if you have a specific question about your child’s setup, I’m easy to reach.
Get the tool right, and let the swing take care of itself.
