A rugby ball is an elongated ellipsoidal ball used in both codes of rugby football. Its measurements and weight are specified by World Rugby and the Rugby League International Federation, the governing bodies for both codes, rugby union and rugby league respectively.
The rugby ball has an oval shape, four panels and a weight of about 400 grams. It is often confused with some balls of similar dimensions used in American, Canadian and Australian football.
William Gilbert started making footballs for the neighbouring Rugby School in 1823. The balls had an inner-tube made of a pig's bladder. Both men owned boot and shoe making businesses located close to Rugby school.[1] In 1870, Richard Lindon introduced rubber inner-tubes and because of the pliability of rubber,
the shape gradually changed from a sphere to an egg. Lindon and Bernardo Solano started making balls for Rugby School out of hand stitched, leather casings and pigs' bladders. The rugby ball's distinctive shape is supposedly due to the pig's bladder, although early balls were more plum-shape[clarification needed] than oval. The balls varied in size in the beginning depending upon how large the pig's bladder was.[2]
