Development focus: Fun, movement, and coordination.

For toddlers and very young children, tennis should feel like play. A 17‑inch tennis racket is extremely lightweight and easy to manoeuvre, helping kids explore movement and basic ball skills without strain.

Key priorities at this stage:

• Developing hand‑eye coordination.
• Learning basic movement skills such as running and balancing.
• Building confidence and enjoyment on court.

Development focus: Basic swings and ball contact.

A 19‑inch racket is ideal for young children who are beginning to swing at the ball with more intent. Lightweight rackets paired with soft or low‑compression balls help children experience success early.

Key priorities at this stage:

• Simple forehand and backhand swing shapes.
• Tracking and timing the ball.
• Keeping sessions short, engaging, and fun.

Development focus: Fundamentals and rally skills.

The 21‑inch tennis racket is a popular choice for early primary school‑aged players. At this age, children are better able to coordinate their movements and begin learning basic tennis fundamentals.

Key priorities at this stage:

• Grip awareness and basic technique
• Short rallies over the net.
• Developing footwork through games and drills.

Development focus: Technique and consistency.

A 23‑inch junior racket provides more reach and stability
while remaining easy to control. This size suits children who are starting to
rally consistently and generate their own swing speed.

Key priorities at this stage:

• Improving forehand and backhand technique.
• Learning a basic serve motion.
• Rallying with better control and direction.

Development focus: Control, movement, and point play.

The 25‑inch racket is a key transition size for juniors moving toward full‑court tennis. It allows players to handle faster rallies while maintaining control and good technique.

Key priorities at this stage:

• Consistent baseline rallies.
• Footwork, balance, and court positioning.
• Introduction to scoring, tactics, and match play.

Development focus: Match play and preparation for adult rackets.

A 26‑inch tennis racket is typically the final junior size before progressing to a full‑length 27‑inch adult racket. This size suits stronger juniors who are competing regularly and developing full swings.

Key priorities at this stage:

• Generating pace with control.
• Developing a reliable serve.
• Understanding basic match tactics and patterns.

The transition from a junior tennis racket to a full-size 27-inch adult racket is an important milestone. While age is a helpful guideline, factors such as height, strength, coordination, and technique should carry more weight than age alone.

Most juniors are ready to move to a 27-inch racket between the ages of 11 and 13, once they are comfortable using a 26-inch racket and can swing with control and consistency.

It is generally better to delay the switch rather than move up too early. Juniors who transition to an adult racket too soon may struggle with timing, control, or arm discomfort. When in doubt, staying with a 26-inch racket for longer often supports better long-term development.
