Rugby Balls

Question
What is the difference between an American football and a rugby ball?

Answer
Mr Guest,

American Football:
-11 to 11.25 inches long
-28 to 28.5 inches around lengthwise,
-21 to 21.25 inches around widthwise
-inflated to 12.5 to 13.5 pounds psi
-The NFL and NCAA use the more expensive leather balls, while more junior leagues tend to use synthetic leather or rubber which are less expensive.

Rugby Union ball
-oval with four panels
-traditionally made of brown leather, now generally white synthetic materail.
-28?0 cm (11?1.8 inches) long
-58?2 cm (22.8?4.4 inches) in circumference at its widest point.
-weighs 410?60 grams (14.5?6.2 ounces)
-inflated to 65.71?8.75 kPa (or 9.5?0 psi).

The quick and dirty is the rugby ball is a fat football with no laces and rounded (not pointed tips)

Thank you,
