Junior Tennis Racquet Size Chart: Age & Height Guide for Kids
Choosing the wrong tennis racquet size for a child is one of the most common beginner mistakes parents make. A racquet that is too long or too heavy can slow progress, reduce control, and sometimes cause arm strain.
This guide explains the junior tennis racquet size chart clearly, using age and height, along with coaching insights we use at Infinity Racquet Club when fitting kids for lessons.
Quick Summary (What You Need to Know)
- Junior racquet size depends mainly on the child’s height
- Sizes range from 19 inches to 26 inches
- Oversized racquets slow learning and reduce control
- Correct sizing improves confidence and technique
Why Racquet Size Matters for Junior Players
Children are still developing strength, coordination, and swing mechanics. Using a racquet that is too large forces poor habits early and makes timing difficult.
In coaching sessions, incorrect sizing often leads to late contact, wrist discomfort, frustration during lessons, and slower skill development.
Junior Tennis Racquet Size Chart (Age & Height)
| Child Age | Child Height | Racquet Length |
|---|---|---|
| 3–4 years | Under 40 inches (102 cm) | 19 inches |
| 4–5 years | 40–43 inches (102–110 cm) | 21 inches |
| 6–8 years | 43–49 inches (110–125 cm) | 23 inches |
| 8–10 years | 49–55 inches (125–140 cm) | 25 inches |
| 9–12 years | 55–59 inches (140–150 cm) | 26 inches |
If a child falls between two sizes, choose the smaller racquet. Control always matters more than reach.
How Coaches Choose the Right Racquet
Charts provide guidance, but coaches also look at how a child moves and swings with the racquet.
A simple check is to have the child hold the racquet normally. If the racquet head drags on the ground when their arms are relaxed, the racquet is too long.
Common Junior Racquet Sizing Mistakes
- Buying a bigger racquet so the child can “grow into it”
- Choosing based on brand instead of size
- Letting kids use adult racquets too early
- Ignoring comfort and swing freedom
When Should Kids Switch to an Adult Racquet?
Most children transition to adult racquets when they are taller than 150 cm and can control a 26-inch junior racquet comfortably.
This usually happens between 11 and 13 years, but coordination and technique matter more than age.
Does Brand Affect Junior Racquet Size?
Racquet length is standard across brands. A 23-inch racquet is the same length whether it is Wilson, Head, or Babolat.
For beginners, correct sizing is far more important than brand choice.
Why Proper Sizing Helps Kids Improve Faster
Correct racquet size allows cleaner contact, easier swing paths, and better consistency during rallies.
Children using the right equipment gain confidence faster and enjoy lessons more.
