Caster Wheel by Tread Width
It’s easy to confuse a caster wheel’s width with its diameter. But while the diameter of a caster wheel measure’s the caster’s overall height, the width measures the tread of the caster, the part that makes contact with the ground when it rolls.
Caster Sizing Information
When measuring a caster wheel’s width, you’re measuring the tread of the wheel: the part that makes contact with the ground when it rolls. Simply measure from the outside of one end of the tread to the outside of the opposite end.
