The ball used in football (soccer) is called a football (or soccer ball). Law 2 of the game specifies that the ball is an air-filled sphere with a circumference of 68–70 cm (or 27–28 inches), a weight 410–450 g (or 14–16 ounces), inflated to a pressure of 8–12 psi, and covered in leather or "other suitable material".[1] The weight specified for a ball is the dry weight: older balls often became significantly heavier in the course of a match played in wet weather. The standard ball is a Size 5. Smaller sizes exist; Size 3 is standard for team handball; others are used in underage games or as novelty items.

[edit] Construction

Most modern footballs (soccerballs) are stitched from 32 panels of waterproofed leather or plastic: pigskin, 12 regular pentagons and 20 regular hexagons. The 32-panel configuration is the spherical polyhedron corresponding to the truncated icosahedron; it is spherical because the faces bulge due to the pressure of the air inside. The first 32-panel ball was marketed by Select in the 1950s in Denmark. This configuration became common throughout Continental Europe in the 1960s, and was publicised worldwide by the Adidas Telstar, the official ball of the 1970 World Cup.

Older balls were usually stitched from 18 oblong non-waterproof leather panels, similar to the design of modern volleyballs and Gaelic footballs, and laced to allow access to the internal air bladder. This configuration is still common.

The official FIFA World Cup football for Germany 2006 matches was the 14-panel Adidas +Teamgeist. It was made in Thailand by Adidas, who have provided the official match balls for the tournament since 1970, and is a "thermally bonded" machine-pressed ball, rather than a traditionally stitched one. For future world cups, FIFA is hoping to alternate between Nike and Adidas for match balls.[citation needed]

Another ball with an innovative pattern is the 26-panel Mitre PRO 100T.

There are also indoor footballs, which are made of one or two pieces of plastic. Often these have designs printed on them to resemble a stitched leather ball.
