Tennis Size Guide for Schools: Choosing the Right Rackets, Balls, and Nets for Every Age Group

Having the right size tennis equipment is essential for supporting students’ development and progression in the sport. Using correctly sized rackets, balls, and nets helps young players learn proper technique, build confidence, and enjoy the game from the start. Equipment that’s too large or heavy can hinder coordination and slow skill development, while age-appropriate options make tennis more accessible and engaging for all ability levels. This tennis racket size guide is designed to help PE teachers and schools choose the right equipment for each age group, ensuring every pupil has the best possible foundation to develop their skills safely and effectively.

Which Tennis Racket Size Is Best for Children?

Selecting the correct tennis racket size is vital for helping school pupils learn and progress with confidence. The right racket allows children to develop proper technique, improve control, and reduce the risk of injury as they grow.

Using a racket that’s too heavy or long can make strokes harder to master and slow development. By following a trusted Tennis Racket Size Guide, schools, coaches, and parents can ensure every pupil uses equipment suited to their height and ability.

Choosing the right size from the start helps young players build good habits, enjoy the game more, and develop at the right pace. Below, you’ll find our easy-to-read size guide graphic, followed by detailed explanations of each racket size to help you choose the perfect fit for every pupil.

The following information, along with that found in the size guide above, is based on details outlined by the Lawn Tennis Association (LTA, 2021). It’s important to note that the correct tennis racket size for children depends on multiple factors — including their age, height, arm length, and playing ability. The information provided should therefore be used as a general guide to help identify the most suitable racket size.

Simple Racket Sizing Trick from the LTA

A simple way to check if a tennis racket is the right length for a child is to have them stand upright with their arms relaxed by their sides. Ask them to hold the racket pointing downwards. If the tip of the racket reaches their ankle, it’s likely the correct size.

17-23" Racket – Ages 8 and Under (Reception–Year 3)

Children aged 8 and under usually need a junior racket between 17 and 23 inches — lightweight and easy to handle for better control and confidence.

When selecting a racket size, consider height, arm length, and experience. A 19-inch racket is a popular choice for beginners, offering a good balance of comfort and control. As children grow in both height and skill level, 21" and 23" rackets provide a smooth progression. These sizes offer better reach and power while still being manageable for younger players.

23–25" Racket – Ages 8–9 (Year 4)

Children aged 8 to 9, typically in Year 4, benefit from using a junior tennis racket sized between 23 and 25 inches. This range supports growing players who are developing better coordination, strength, and technique. A 23-inch racket is ideal for those still building confidence, while a 25-inch racket suits taller or more advanced players. Choosing the right tennis racket size for kids at this age helps improve control, swing mechanics, and overall enjoyment of the game. Whether you're a PE teacher, coach, or parent, this guide makes selecting the best junior tennis racket simple and effective.

25–26" Racket – Ages 9–10 (Year 5)

A 25-inch tennis racket is ideal for most children in Year 5 who are developing stronger coordination and technique. It offers a good balance of control and reach, making it suitable for players who are still refining their swing mechanics.

For taller or more advanced players in Year 5, a 26-inch racket provides additional reach and power. It’s a great choice for children who are ready to transition toward larger frames and more competitive play.

26–27" Racket – Ages 10+ (Year 6+)

As children reach the final year of primary school and Key Stage 2, many will benefit from using a 26-inch tennis racket — the last step in junior racket sizing before transitioning to a full-sized model. This size supports their physical development and growing technical ability, helping them prepare for more advanced play. Once ready, they can move on to the final progression: a 27-inch adult racket, designed for players with the strength, coordination, and skill to handle full-size equipment confidently.

Our tennis ball range is colour-coded in line with LTA recommendations LTA (2025), ensuring each ball type supports the appropriate stage of player development. This alignment helps schools and coaches deliver sessions that meet national standards for progression and play.

Matching Ball Type to Player Progression: Why It Matters

Just as tennis racket sizing is linked to a player’s age, height, and ability, the type of tennis ball used should also reflect their stage of development. While progression is based on skill rather than age alone, many coaching resources provide rough age guidelines to help schools and coaches choose the right equipment. Reputable coach Elly Shearman offers a helpful breakdown of the different coloured balls and their uses on her website, explaining how each supports specific stages of learning and play. You can read her full explanation here.

Choosing the right tennis ball for each age and stage helps young players develop skills, build confidence, and enjoy the game at the right pace. Below, you’ll find our easy-to-follow colour guide graphic, followed by a breakdown of each ball type to help you make the best choice for your pupils.

Red Ball – Ages 5-8 (Reception-Year 3)

Red Ball tennis is the perfect introduction to the sport for children aged 5 to 8. These low-compression balls bounce slower and lower, making it easier for young players to develop coordination, timing, and basic rallying skills. Played on mini courts, Red Ball sessions focus on fun, movement, and learning to serve, rally, and score—building a strong foundation for future progression.

Orange Ball – Ages 7-9 (Years 2-4)

Orange Ball tennis is designed for children aged 7 to 9 who are ready to build on their foundational skills. These medium-compression balls bounce lower and slower than standard balls, allowing players to develop proper technique and tactical awareness on a slightly larger court than Red Ball tennis. At this stage, children begin to play structured points, understand positioning, and explore singles and doubles play—laying the groundwork for confident, competitive tennis.

Green Ball – Ages 9-10 (Year 5-6)

Green Ball tennis is ideal for players aged 9 to 10 who are ready to transition to a full-sized court. These slightly decompressed balls offer a balance of control and speed, helping children refine their technique, timing, and movement. With standard tennis scoring and shorter sets, Green Ball matches introduce players to more realistic gameplay while keeping it manageable for their age and strength. It’s also a great option for older beginners looking to build confidence and skill.

Green Ball – Ages 9-10 (Year 5-6)

Yellow Ball – Age 11+ (Year 6+)

Yellow Ball tennis is the final stage in the development pathway, typically for players aged 11 and up. At this level, children play with standard tennis balls on a full-sized court, using full scoring and match formats. For those who’ve progressed through Red, Orange, and Green stages, Yellow Ball tennis focuses on refining technique, improving movement, and developing tactical awareness. It’s also suitable for older beginners, who may revisit skills from earlier stages while building confidence and game understanding.
