What Age Group Uses a Size 4 Rugby Ball?
Size 4 is the standard rugby ball for junior players from roughly U10 through to U14. It sits between the size 3 used in mini rugby and the full-size 5 used from U15 upward. Here's the rough age guide:
- Size 3 - mini rugby, Ages 6 - 9 years old
- Size 4 - junior rugby, Ages 10 - 14 years old
- Size 5 - senior rugby, Ages 15 and above
Some clubs vary slightly in how they apply these guidelines, but this is the standard framework across most junior rugby in the UK. If you're buying for a specific age group and unsure, a size 4 covers most players in the 10-14 age bracket.
Size 4 Rugby Ball Dimensions
A size 4 rugby ball is smaller than a full-size 5 but noticeably larger than a size 3 ball. It measures approximately 25-27cm in length and 54-57cm in circumference when properly inflated. The correct inflation pressure is broadly the same as a size 5 - around 9-10 PSI - though junior training balls are sometimes inflated slightly softer for easier handling.
Match, Training and Replica Size 4 Balls
Size 4 balls split into the same categories as the full range. Match balls are built to proper specifications for competitive junior fixtures. Training balls are more durable and suited to heavy use on the training ground. Replica balls carry a team or tournament design and are popular as gifts for junior players who support a specific nation.
