Inflate soccer balls to the pressure of 6-8 PPI (pounds per square inch). A pressure gauge will tell you when the air is enough. Under or over-inflating a soccer ball will shorten its life in one way or another. When under-inflated, the ball will not be resistant to the impact of kicks. On the other hand, over inflation will stretch out the bladder and put pressure on the panel stitches.
Today's footballs are more complex than past footballs. Most modern footballs consist of twelve regular pentagonal and twenty regular hexagonal panels positioned in a truncated icosahedron spherical geometry. Some premium-grade 32-panel balls use non-regular polygons to give a closer approximation to sphericality. The inside of the football is made up of a latex bladder which enables the football to be pressurised. The ball's panel pairs are stitched along the edge; this procedure can either be performed manually or with a machine. The size of a football is roughly 22 cm (8.65 inches) in diameter for a regulation size 5 ball. Rules state that a size 5 ball must be 68 to 70 cm in circumference. Averaging that to 69 cm and then dividing by π gives about 22 cm for a diameter.
Furthermore, cleaning the ball is a very important task that you must do on a regular basis. It could help you avoid water absorption issues, and it will help make it last longer. Clean a soccer ball with some mild soap and lukewarm water to maintain its performance. Don’t use harsh cleaning agents as this might damage the ball’s construction material. Storing the ball in low temperatures is ideal to avoid warping or water retention. https://www.youtube.com/watch?v=_TX8dExPIWc
