There are a few variables to keep in mind. If you want to practice your skills and footwork, a size 1 ball is recommend. A size 3 ball is best suited for children ages 8 and younger, whereas a size 4 ball is best for ages 8-12, or a size 5 ball for ages 13 and up. With that in mind, many soccer leagues and clubs have their own specifications when it comes to ball size. If you play on a league, it is recommended to check their regulations first.
In the year 1863, the first specifications for footballs were laid down by the Football Association. Previous to this, footballs were made out of inflated leather, with later leather coverings to help footballs maintain their shapes. In 1872 the specifications were revised, and these rules have been left essentially unchanged as defined by the International Football Association Board. Differences in footballs created since this rule came into effect have been to do with the material used in their creation.
Size 5 is the official size for professional matches. Therefore, this ball is only available in this size. Do not use this soccer ball on concreted areas. Its unique rubber uses Puma Airlock Valve Technology (PAL) in order to facilitate proper airlock technology. This ball features Perimeter Balance Technology (PBT) which enables it to maintain impressive flight characteristics. https://www.youtube.com/watch?v=j2Xn84L3Kcs
