Size of the ball

[Aout]

Hi there,

I'd like to know what is the official size of rugby union balls (i.e. the ones that are used for the Hcup, Top14, Guiness Premiership, ...).

After a quick search on the web I found this text :

<div class='quotetop'>QUOTE </div>

It [the ball] weighs 410–460 grams (14.5–16.2 ounces) and is inflated to 65.71–68.75 kPa (or 9.5–10 psi).[/b]

(source : Wikipedia , http://en.wikipedia.org/wiki/Football_(ball)#Rugby_union)

and here is the weighs of the XT400 Gilbert balls :

Size 3 0.34 kg
Size 4 0.37 kg
Size 5 0.45 kg

Does it mean that the only official size is the size 5 (because it's the only one whose weigh is between 410-460 grams) ?

Yup, size 5 is the official size for games and the such

Size 5 for adult rugby.
The other sizes are smaller for age group games.
