How Big Is an NFL Football? Official Size & Weight

By Sarah Miller · April 27, 2047

An NFL football is 11 to 11.25 inches long, has a circumference of 28 to 28.5 inches at its widest point, and weighs between 14 and 15 ounces (397–425 grams). These precise dimensions are standardized by the National Football League to ensure consistency in gameplay, grip, and performance across all official games.

Official NFL Football Dimensions Explained

The size and weight of an NFL football are strictly regulated to maintain fairness and uniformity in professional American football. These standards apply to all game balls used during regular-season and postseason play.

Key Size Specifications

Length: 11 to 11.25 inches (27.9 to 28.6 cm)
Circumference (long axis): 28 to 28.5 inches (71.1 to 72.4 cm)
Circumference (short axis): 21 to 21.25 inches (53.3 to 54 cm)
Weight: 14 to 15 ounces (397 to 425 grams)
Bladder pressure: 12.5 to 13.5 psi

These measurements ensure that the ball fits comfortably in a quarterback’s hand while allowing for accurate throwing, catching, and handling under various weather conditions.

Comparison Across Football Leagues

Different levels of football use slightly different ball sizes. While the NFL enforces strict regulations, other leagues such as college (NCAA), high school (NFHS), and youth football have their own specifications tailored to player age and strength.

League	Length (inches)	Long Circumference (inches)	Weight (oz)	Ball Designation
NFL	11.0–11.25	28.0–28.5	14–15	Pro Grade
NCAA (College)	10.875–11.125	27.75–28.5	14–15	College Football
NFHS (High School)	10.875–11.125	27.75–28.5	14–15	Youth/HS Ball
Youth Football	8.5–10.5	24.5–26.5	12–13.5	Youth Size

The data shows minimal differences between NFL and college/high school footballs, with youth versions being significantly smaller and lighter. The near-identical specs for NCAA and NFHS allow players to transition smoothly into professional play.

Materials and Construction of an NFL Football

NFL footballs are made from genuine leather, specifically cowhide, tanned to provide durability and grip. The ball features eight panels stitched together with nylon thread, including a distinctive white lace at the top seam to assist quarterbacks in gripping and aligning the ball during throws.

Why Cowhide Leather?

Superior grip compared to synthetic materials
Withstands harsh outdoor conditions (rain, cold, turf)
Breaks in naturally over time for better feel
Preferred by elite quarterbacks for control

Each ball is handcrafted by Wilson Sporting Goods, the exclusive supplier of NFL game balls since 1941. Approximately 70,000 official game balls are produced annually for league use.

How Size Impacts Game Performance

The standardized size of an NFL football directly affects gameplay mechanics, including passing accuracy, catching ability, and running efficiency.

Impact on Quarterbacks

Larger hands can wrap around the ball more securely
Precise finger placement on laces enables spiral throws
Consistent weight allows for reliable arm motion and timing

Receivers and Running Backs

Optimal size improves one-handed catches
Textured leather enhances ball security during contact
Uniform shape aids in tracking flight trajectory
