How much does an NFL football weigh?

An official NFL football weighs between 14 and 15 ounces when properly inflated (396 to 425 grams). The length is 11 inches, and the circumference is 22 inches. 

When it was formed in 1920, the NFL was known as the American Professional Football Conference. After another name change, it wasn’t until 1922 that it was given its current moniker, the National Football League.

The Super Bowl is, of course, the most popular event in the NFL. Every year, more than 100 million people watch it. A 30-second commercial during the Super Bowl will cost you about $3 million. However, that expense rises year after year.

Mass of American football

Textbooks and lectures frequently convey material in such a way that it appears to be true. In the instance of football mass, every source I discovered had the same numerical figure for football mass. 

According to the Oxford Companion to World Sports and Games, the official National Football League Encyclopedia, the NFL make the right callbook, and the football fun facts sheet, the weight of a football used in an NFL game must be between 14 and 15 ounces (0.40 to 0.43 kg).

Football developed from rugby, which grew from soccer. All that was official when the game of football (American) was created was the shape of the ball, which looked like “an elongated pumpkin” and was later dubbed a prolate spheroid. The weight of a football was determined in 1912 to be 14 to 15 ounces.

The referee must check all twenty-four balls (if the game is played in a domed stadium) or thirty-six balls (if the game is played in an open-air stadium) before each professional football game. This is done visually, ensuring that each ball is a Wilson ball signed by the NFL commissioner.

The size and form of the ball are further checked by inserting each ball in a mold that each referee owns.

What Is the Official Size of NFL Football?

The National Football League (NFL) is a professional football league composed of the greatest players in the globe. The NFL, like other levels of football, utilizes an egg-shaped football, but the size, form, and materials used for the football are all regulated by the NFL. The NFL Digest of Regulations provides the official size specifications for footballs, as well as other essential rules for playing the game.


The NFL has established measuring guidelines for the total length and greatest circumference at the football’s center. An official NFL football is somewhat larger than a high school football or a football from another professional league. The length should be around 11 inches from tip to tip, and the diameter should be about 22 inches in the middle of the football.


Overall weight and air pressure are also important in the NFL. The football and materials weigh around 14 to 15 ounces, and the ball is inflated to approximately 12.5 to 13.5 lbs. per square inch. These weight and air pressure measurements provide uniformity among the several footballs used in a game.


The dimensions of materials, the number of layers, and the pattern of design are all governed by NFL regulations. Before being stitched together, four leather panels are weighed, measured, and examined for flaws. White leather laces are used to sew the top two panels together. A 3-ply VPU rubber bladder or inner lining retains the air inside the leather panels.


The home club provides 36 footballs for outdoor games and 24 footballs for indoor games before each NFL football game. An extra 12 footballs are labeled with the letter “K” and are only used for kicking. Every football is inspected by the referee two hours before the game to verify it matches the official size, weight, and air pressure criteria.

Ball Supply

To satisfy League standards, each side shall make 12 primary balls accessible for testing by the Referee two hours and 15 minutes before the game begins. In addition, the host club will provide 12 backup balls for testing in all venues. 

In addition, during games played in outdoor venues, visitors may carry 12 backup balls to be examined by the Referee. For all games, eight new footballs will be opened in the officials’ locker room two hours and 15 minutes before the game’s start time, sealed in a unique box, and sent by the manufacturer to the Referee.

The Referee will mark these balls specifically and they will only be used during the kicking game. If a home team ball does not meet standards or the supply is depleted, the Referee must obtain a proper ball from the visitors or, failing that, use the best available ball. Such events must be reported to the Commissioner. A playable ball should be utilized at the request of the attacking team’s center in the event of rain or a wet, muddy, or slippery field. The Game Clock shall not be stopped as a result of such action (unless undue delay occurs).


Finally, the Referee is the sole decider of whether all balls provided for a play meet these requirements. The host club must supply a pump, and the balls must stay under the observation of the Referee until they are given to the ball attendant immediately before the start of the game.
