Most sports brands will label kids’ shin guards according to age until about 16. So for kids, it is best to measure how tall the child is in comparison to the average height for that age and then buy the shin guards depending on this. At the same time, if you’re wearing shin guards that don’t fit, injuries are just as likely. It will also cause lots of discomfort for the player as the shin guards will potentially move around while running. Certain types of collisions could force the guards into the leg and could actually cause an injury worse than if the performer wasn’t wearing any shin guards at all. This is why it is vital that you buy a pair of shin guards that are fitted to your leg... no one wants an injury and you should ask yourself 'What Size Shin Guards do I need?"

These are measured on the height of the adult and as mentioned, for the soccer players that are slightly thinner or wider than the average person, sports brands make shin guards specifically to fit these people.
