The origin of Rugby in England goes back long into the 19th century and even earlier. In 1800's formalities were introduced to football rules in the seven major public schools of England. Six of the seven schools were largely playing the same game (including Eton, Harrow and Winchester) - while the seventh, Rugby School (founded in 1567) at Warwickshire, was playing a markedly different version of football.

Therefore in the 1860s, it came as great relief when the inflatable rubber bladder was invented by Richard Lindon to replace the pigs'. Indeed, with the ease of handling rubber as opposed to the stiffly circular bladders of pigs, this led to a change in shape of the rugby ball from a sphere to an egg. Interestingly though, the rugby football never came to be termed footegg. Susceptible to water-logging even with the use of preservative cod oil and tallow rubs, the leather casing at the end of the ball was possibly too long, and it was only during the 1980s that modern weather-proof synthetics were introduced. In 1892, the RFU set oval dimensions for the ball and the ball was progressively flattened over time.
In 1892, the dimensions and features of the ball were fixed at:
- Length: 11 to 11 ¼ in
- Circumference (end to end): 30 to 31 in
- Circumference (in width): 25 ½ to 26 in
- Weight: 12 to 13 oz
- Hand-sewn with 8 or more stitches to the inch.
Nowadays, the modern ball is a hybrid of polyurethane, synthetic leather, foiled polyester, latex and adhesive, effective in keeping the ball intact and durable.
At present, the 2004 IRB (International Rugby Board) officiates:
- Structure of the ball: oval and constitutes 4 panels
- Length in line: 280 to 300 mm
- Circumference (end to end): 740 to 770 mm
- Circumference (in width): 580 to 620 mm
- Material: Leather or appropriate synthetic material (allowed to be conditioned for better grip and to make the ball water-resistant)
- Weight: 410 to 460 g
- Internal air pressure at start of game: 65.71 to 68.75 kPa (or 0.67 to 0.70 kgcm -2)
