Wheel Size: Inline skate wheels for kids typically run in size between 70-79mm. These wheels are found on recreational skates. Kids are just learning how to skate and are much smaller than adults and therefore don’t need the big speed skating wheels. On aggressive skates the wheels are between 50-59mm which is much smaller as aggressive skaters are less interested in acceleration, and more interested in control for performing tricks and jumps.
