Ball
Defines the shape, size, and weight of the rugby ball used in matches.
What it says
The ball must be oval, made of four panels, and fall within a size and weight range set by World Rugby. Its irregular shape is what causes the unpredictable bounce rugby is known for.
Why it exists
A standard ball means the game plays consistently wherever it's used, from a school pitch to a World Cup final. The oval shape is also central to the sport's identity, since passing, kicking, and catching an oval ball is a different skill entirely from a round one.
In practice
Smaller ball sizes are used at junior levels to suit smaller hands, while professional and adult matches use a standard size. Weather affects handling more than in most sports because of the shape, since a wet ball is genuinely harder to catch and pass cleanly.
Common confusions
The odd bounce of the ball isn't just bad luck or poor handling. It's a direct, designed consequence of the oval shape, and turning that unpredictability to your advantage is part of the actual skill of the game.
