Which Tennis Racket Should My Kid Use? The Complete Junior Racket Guide
Choosing the right tennis racket for your child might seem simple, but it has more impact than most parents realize. A racket that does not match your child's age, skill level, or height works against their technical development and even increases the risk of injury.
In this guide, we walk you through, step by step, what to look for when choosing a junior tennis racket: from the right racket length based on height and racket weight, to the different materials, quality levels, junior rackets by playing level and experience, and the transition to a senior racket. This way, you can help your child get the most fun and best performance out of the ideal junior racket.

How do you choose the right junior tennis racket?
When choosing a junior tennis racket, one thing matters most: the racket needs to match your child's physical development. A racket that is too heavy or too long makes technique harder and drags on the ground during play, while a racket that is too small holds back a taller child in terms of reach, stability, and power.
Before you start looking at specific models, it helps to think through the following:
How old is your child? This gives you a first indication of the right racket length.
How tall is your child? Height is hugely important for determining the right racket length. Taller kids can often handle a bigger junior racket sooner.
What is their skill level? Is your child just starting out with tennis, or have they been playing for a while? Are they taking lessons, and are they progressing quickly?
How often does your child play? Are you working toward competitive tournaments, or is this mainly for recreational fun? Does your child play once a week for leisure, or do they have training sessions and matches several times a week?
Answering these questions lets you search specifically for a racket that supports your child's development instead of getting in the way of it.
Racket length: based on height and age
Racket length is the most important factor when choosing a junior tennis racket. A racket that is too long is hard to swing without hitting the ground and is often too heavy, which leads kids to develop flawed technique. A racket that is too short does not offer enough reach and forces the child into unnatural movement relative to the ball. It also takes extra effort to generate enough ball speed with a racket that is both too short and too light.
Junior tennis rackets come in standard lengths that are often matched to age groups, but your child's height is the most reliable measure to go by.
| Racket Length | Body Height | Age |
|---|---|---|
| 17 in | Up to 90 cm (3 ft) | 2-3 yrs |
| 19 in | 90–105 cm (3–3.5 ft) | 3-5 yrs |
| 21 in | 105–120 cm (3.5–4 ft) | 4-6 yrs |
| 23 in | 120–130 cm (4–4.3 ft) | 6-8 yrs |
| 25 in | 130–140 cm (4.3–4.6 ft) | 8-10 yrs |
| 26 in | 140–150 cm (4.6–4.9 ft) | 10-12 yrs |
| 27 in | From 150 cm (4.9 ft) | 12+ yrs |
How do you check for the right racket length?
Getting the racket length right is essential for your child's tennis development, both for effectiveness and safety. Here is how you and your child can check whether a junior racket is the right size, in three simple steps!
1. The correct grip
Make sure your child holds the grip correctly. Place the hand at the bottom of the grip, with all fingers relaxed around it. There should be about half a centimeter (roughly a quarter inch) of space left at the end of the grip, between the hand and the butt cap.
2. Stand up straight
Make sure the child stands upright with shoulders square and legs together.
3. Racket to ankle
Let the racket hang straight down along the body. If it is the right length, it should end around the ankle. If the racket touches the ground, it is too long and you will need a smaller size. If it stops well above the ankle, it is time to move up to a bigger racket.
Why does the right racket length matter so much?
A racket that is too big for a child means their strokes end up coming from the arm alone, instead of the shoulder and body. This leads to flawed technical fundamentals that are harder to correct later on. On top of that, a racket that is too heavy raises the risk of overuse injuries to the arm, wrist, and shoulder.
A racket that is too small limits stability at ball impact and restricts a child's reach, which gets in the way of developing full strokes as the child grows. A smaller, lighter racket also has less mass, forcing a bigger child to compensate too much and hit harder with strength rather than technique.
The weight of a junior racket
Just like with adult rackets, the weight of a junior tennis racket is a crucial factor. Junior racket weight naturally increases as racket length increases: a 17-inch racket weighs considerably less than a 26-inch one.
The right weight for your child is always the racket they can swing through completely, with a full motion, without having to put in extra effort or sacrificing technique.
The bigger the child, the heavier the racket
Junior rackets from 17 to 21 inches, made for the youngest players, typically weigh between 135 and 195 grams (about 4.75–6.9 oz). From 23-inch frames onward, weight climbs above 200 grams, sometimes reaching as much as 255 grams (roughly 9 oz) in a 26-inch racket.
That said, weight can also vary between models of the same size, often tied to the racket's playing characteristics. For example, the Wilson Blade 26 V10 weighs 255 grams, giving this control-oriented model some extra pop on the ball, while a power-oriented frame like the HEAD Boom Jr. 26 2026 weighs 245 grams, for extra maneuverability and more control over the racket during the swing.
| Racket Length | Typical Weight |
|---|---|
| 17 in | 135–150 g (4.75–5.3 oz) |
| 19 in | 150–170 g (5.3–6 oz) |
| 21 in | 180–195 g (6.3–6.9 oz) |
| 23 in | 195–215 g (6.9–7.6 oz) |
| 25 in | 210–220 g (7.4–7.8 oz) |
| 26 in | 225–240 g (7.9–8.5 oz) |
| 27 in | 240–255 g (8.5–9 oz) |
Too light vs. too heavy
Too light
A child using a racket that is too light will not get enough benefit from the racket's stability and mass. They will notice the ball does not come off the strings with much pop, which can take away from the fun. For older, stronger juniors, a racket that is too light can actually work against them, since it does not match the power they are already able to generate.
Too heavy
A child using a racket that is too heavy does not have enough strength to control it well. The arm has to work too hard, technique suffers, and the risk of overuse injuries goes up. This is especially important to watch for with young kids who are still developing physically.
The balance of a junior racket
Just like with adult tennis rackets, the balance point of a junior racket affects maneuverability, stability, and how much mass gets transferred to the ball at impact. Relatively speaking, junior rackets almost always have a higher (more head-heavy) balance point. That is partly just because they are shorter, but it is also intentional: a higher balance point helps a child generate ball speed even with short, not-yet-fully-developed strokes. This makes the game more accessible and adds to your child's enjoyment.
As junior players get bigger and stronger and their stroke technique develops further, they will move on to longer rackets, eventually reaching 27-inch adult frames. Over time, balance points tend to shift toward even balance or head-light, for the ideal combination of maneuverability, stability, control, and the power that comes with it.
The different frames and quality levels of junior rackets
Junior rackets are made from a range of different materials, which have a huge impact on the playing experience. You will find rackets made of aluminum, composite, and even full graphite.
Aluminium
Aluminium junior rackets are available in every size, from 17 to 26 inches. They generally come at a lower price point, making them an appealing first racket for young beginners. That said, these are entry-level kids' rackets with the least amount of comfort. They are perfectly suited for getting started and getting a feel for the game. Is your child playing several times a week? Then it is worth considering one of the two higher quality levels and picking up a composite or graphite junior racket instead.
Composite
Composite junior rackets are available from 21 to 26 inches. "Composite" means they are built from a combination of aluminum and graphite, sometimes with fiberglass mixed in too. The exact material mix can vary a lot within this category, so playing experience and comfort vary between models as well. Generally speaking, though, composite kids' rackets offer good value for money and a more enjoyable, more comfortable playing experience than aluminum rackets. That makes them a good fit for beginners and slightly more advanced young players. Is your child playing a lot of tournaments and matches, and training several times a week? Then consider a full graphite junior racket for more comfort and a better playing experience.
Graphite
Graphite junior rackets are mainly produced in the larger sizes, 25 and 26 inches. These are the highest-quality rackets and offer the most comfortable playing experience with the best vibration dampening. Starting at this category, kids' rackets also show a clearer distinction between frame types and their matching specs, bringing them closer to the adult rackets in the same racket family. For example, a Yonex EZONE is designed for extra power, while a Wilson Blade offers more control. From beginners to dedicated tournament players, graphite junior tennis rackets suit any young player ready for a 25- or 26-inch frame.
| Aluminium | Composite | Graphite | |
|---|---|---|---|
| Experience | ✪ | ✪✪ | ✪✪✪ |
| Basic, less refined | Good balance of power and control | Great feel and control | |
| Comfort | ✪ | ✪✪ | ✪✪✪ |
| Less vibration dampening | Average to Good | Great vibration dampening | |
| Price | ✪ | ✪✪ | ✪✪✪ |
| Pros | Lower purchase price | Good value for money | Power, control, and comfort |
| Cons | Less feel and comfort | Characteristics vary a lot by material mix | Higher purchase price |
Junior rackets by playing level and experience
While racket length and weight are the foundation, your child's playing level and experience also matter when making a choice. For dedicated young players, having top-quality materials becomes increasingly important, not just to minimize injury risk, but also for optimal performance and to support their tennis development.
Beginners (just starting out with tennis)
For kids picking up a racket for the first time, who want to find out whether they enjoy tennis before deciding whether to stick with it, entry-level junior rackets are usually a great fit. Aluminum rackets in the right size let your child experience the sport and are available at the most accessible price point.
Is your child starting to play tennis and planning to play several times a week over a longer period? Then go for a composite or full graphite racket in the right size. These add to the fun, offer a more comfortable playing experience, and provide better support for developing proper strokes.
For beginning junior players: a relatively light racket with as much stability as possible and easy access to power helps with learning the basic techniques of tennis.
Slightly more advanced junior players (regular training or club tennis)
Kids who have been playing tennis for a while and are taking lessons generally need a racket that feels comfortable over longer periods, offers enough consistency, and has the mass and stability to handle the higher ball speeds that come with a rising skill level.
With that in mind, aluminum rackets typically will not cut it anymore for kids with some tennis experience under their belt. Go for a composite or full graphite junior racket instead. These materials simply offer better vibration dampening and more stability, even at a lower weight.
For slightly more advanced junior players: comfort and stability become more important for frequent, long-lasting enjoyment and consistent racket performance. As technical development progresses and skill level rises, the playing characteristics of different junior racket types become increasingly relevant.
Advanced juniors (competitive players)
Kids who have been playing tennis for a long time, take lessons, and also compete in matches and tournaments benefit the most from top-quality junior rackets. They are experienced and usually technically developed enough to choose a racket that matches their playing style: more power, more control, lighter and more maneuverable, or heavier and more stable.
You will find these characteristics mainly in full graphite junior rackets. On top of that, rackets made from this material also offer the smoothest transition to adult tennis rackets.
For advanced junior players: comfortable materials matter a great deal, given how often they play and the more powerful ball impact during strokes. The racket's characteristics need to support the child's playing style and make the eventual move to adult tennis rackets feel as natural as possible.
The transition to an adult racket
A question parents ask often: when can my child move up to a 27-inch adult racket? The answer depends on three factors: height, technical development, and physical strength.
When is a child ready for an adult tennis racket?
From a height of around 150 cm (4.9 ft), a child could try out a light 27-inch adult racket, with the emphasis on light. For a junior player making the move to their first adult racket, rackets weighing 255 to 270 grams (about 9–9.5 oz) are often the best choice. Since adult rackets are longer than junior rackets, frames in this weight range make it as easy as possible for junior players to keep executing proper, full strokes.
Do not base your weight choice on height alone. Technical ability and physical strength matter just as much.
Strong juniors with well-developed strokes tend to do better with rackets around 270 grams, while slightly less strong kids, whose strokes still have a lot of technical development ahead of them, are usually better off choosing the lightest adult racket possible, around 255 grams.
The last step: the 26-inch junior racket
A 26-inch junior racket is an excellent last step before actually moving up to a senior racket. It is the largest size in kids' tennis rackets and differs by only one inch, about 2.5 cm, from most adult tennis rackets. Some 26-inch junior rackets even match the weight of the lightest senior rackets. This makes the eventual jump to an adult racket as seamless as possible.
Not sure if your child is ready for an adult racket, and are they currently still playing with a 25-inch or smaller junior racket? Then a 26-inch junior racket might be a safe in-between step.
Would you rather skip that last step entirely? Then we would always recommend trying out a senior racket first. That way, your child can experience on court how a 27-inch racket plays and whether it is the right choice, before you have to commit to a purchase.
Grip size for junior rackets
Just like with adult rackets, grip size matters for comfortable, effective, and safe play with a junior racket. Junior rackets generally come with smaller grips than adult rackets, matched to kids' smaller hands.
How do you determine the right grip size for a junior player?
For the very youngest players, using 17 to 21-inch rackets, there is usually only one grip size option: a small one. The racket simply comes with the grip that matches the smallest kids' racket sizes. With larger junior rackets, from 23 to 26 inches, there is some variation, though it is limited. Often there is little to no choice available. The handle on junior rackets tends to grow along with the racket size. Smaller kids' rackets have smaller grip sizes, while larger kids' rackets have slightly bigger ones.
A good rule of thumb for junior rackets: your child's fingers should not wrap all the way around the handle so that the fingertips press into the palm, but there also should not be a large gap. The middle and ring fingers should sit comfortably and securely around the handle without needing to squeeze hard.
Overgrip for fine-tuning
Want to make the grip a bit thicker for a better fit? You can wrap an overgrip around the replacement grip. It is a simple way to make a racket more comfortable for your child if the grip size is just a touch too small.
Frequently asked questions about tennis rackets
Over the years, we've have been asked a lot of questions. Below is a list of frequently asked questions and answers.
Even though tennis brands specify which ages certain junior racket sizes are designed for, that is only a guideline. Your child's height matters more than their age.
Kids between about 90 and 130 cm (roughly 3–4.3 ft) tall usually do best with junior rackets from 19 to 23 inches. The age range that typically goes with this is 3 to 8 years old. For junior players between about 130 and 150 cm (4.3–4.9 ft) tall, it is common to use the two largest kids' racket sizes: 25 and 26 inches. These kids are estimated to be roughly 8 to 11 years old.
How often and at what level your child plays also affects which frame material makes the most sense. Beginners who do not play often can do perfectly well with an aluminum racket, while kids who play more frequently, with growing experience and technical skill, benefit more from composite and full graphite rackets.
That depends entirely on how tall, strong, and technically developed your child is, how heavy the racket is, and what materials the frame is made from. For most kids, a dedicated junior racket will be the best choice. But if your child is around 11 or older, taller than 150 cm (4.9 ft), physically strong, and has been playing tennis for a while then a very light adult racket between 255 and 270 grams could sometimes work, as long as the frame is full graphite.
This depends a lot on how fast your child is growing. Some kids use the same racket for one season, others for several seasons. It is a good idea to regularly check your child's height and playing style to see whether the racket still fits.
Your child's tennis development matters too. Is their level going up, with the ball coming faster and harder? Then they will need a more stable tennis racket to absorb the shock of ball impact and stay comfortable while playing. You will find extra stability and comfort in rackets made from higher-quality materials and in larger sizes. Just make sure the racket does not get too long for the young player. That would make it harder to execute proper swing technique.
Junior rackets are generally sold already strung. The stock string job is usually just fine for most young, recreational players. Is your child playing more intensively and are the strings starting to break, or do you want better playing characteristics? Then it is worth investing in higher-quality strings, just like with adult rackets.
Generally speaking, Tennis Kids Red players, who use red Stage 3 balls, play with junior rackets from 17 to 21 inches. Tennis Kids Orange players use orange Stage 2 balls and typically use 23 to 25-inch junior rackets. Tennis Kids Green players, who use green Stage 1 balls, are the oldest and tallest junior players. That is also why they generally use the largest junior racket sizes: 25 and 26 inches.
Playing with the right ball for each racket size creates a playing experience that matches the child's skill level. A standard yellow ball, the kind used by adults, bounces too fast and too high for young kids, which gets in the way of technical development, puts too much impact on young players' arms, and makes the game far too difficult.
Conclusion: How to choose the right junior tennis racket!
Let us run through the key points one more time:
- Use your child's height as the primary guide for racket length. Age is just an indication, kids of the same age can vary a lot in size. The racket needs to be light enough to swing all the way through.
- Make sure the weight matches your child's strength. A racket that is too light does not offer enough stability; a racket that is too heavy gets in the way of technique and raises the risk of injury.
- Determine the right material and frame quality. The more often your child plays and the higher their level gets, the more important it becomes to have enough comfort and stability in a racket. The playing characteristics of different models matter more and more too. Aluminum is mainly for beginners who want to try tennis out, composite offers somewhat higher quality, and full graphite delivers the best playing experience, the most comfort, and specific benefits like extra control, spin, or power.
- Pay attention to grip size. Fingers should not wrap all the way around the handle, but there should not be a big gap either. An overgrip can help fine-tune the fit.
- Choose the matching ball. A red, orange, or green ball makes the game a lot more fun and accessible for your child's level and age.
- Plan the move to an adult racket deliberately. A 26-inch junior racket is a great in-between step. If your child is not quite there yet, we recommend trying out a senior racket first. Only once your child has enough height, technique, and strength, a senior racket is the right choice.
