The length should measure about 11 inches from tip to tip, and the in circumference at the center of the football should measure about 22 inches. Weight. Overall weight and air pressure are specific in the NFL, too. The football and materials weighs about 14 to 15 oz., and is the ball is inflated to about 12.5 to 13.5 lbs. per square inch.
Youth footballs have an average weight of 12.5 ounces, with a roughly 26.25 inch long circumference and a roughly 19.25 inch short circumference.These footballs are slightly smaller than the high school/college size, which allows younger players to get a better grip when holding the ball.
Law 2 of the game specifies that the ball is an air-filled sphere with a circumference of 68–70 cm (27–28 in), a weight of 410–450 g (14–16 oz), inflated to a pressure of 0.6 to 1.1 atmospheres (60–111 kPa or 8.7–16.1 psi) "at sea level", and covered in leather or "other suitable material".
Y ear round strength and conditioning is now a must for any football team that aspires to a high level of performance.
