Football ball

A foot ball is a spherical or oval object used in some sports. In most of them, the ball must be moved across a pitch by means of body parts or some utensil, in order to be introduced into the goal area. Balls come in different shapes, sizes, weights and materials, depending on the sport in which they are to be used. The ball used in football is made of leather or similar, and has undergone many transformations throughout its history. Although it is usually called a sphere, the truth is that a common football is formed by a truncated icosahedron with twelve pentagons and twenty regular hexagons. The faces of the ball are slightly curved, which influences its aerodynamics, making it easier to apply and control passes.

Dimensions and weight of the football

The football used in professional leagues has the following measurements: its circumference ranges from 79 to 71 centimetres, its weight varies from 400 to 450 grams, its inflation pressure is between 8.5 and 15.6 PSI, its diameter can be between 22 and 23 centimetres and its radius ranges from 11 to 11.5 centimetres. These measurements correspond to a size 5. However, the size of the football is different depending on the age of the players and the game played.

Sizes: football ball for children and youths

  • Size 3 corresponds to the footballs used by children under eight years of age. They weigh around 300 grams and have a circumference of 60 centimetres, making them easier to control.
  • Size 4 is used for playing 7-a-side football. This is also a great choice for children between the ages of eight and twelve. They weigh approximately 350 grams and range in circumference from 64 to 66 centimetres.
  • Size 5 is used in professional football as mentioned above, but is also recommended for children over the age of thirteen.

Therefore, in order to choose the right football, the following should be taken into account: the size, the number of panels, the air chamber, the design and the ground on which it will be used.
