Getting the wheel size of a caster involves two measurements: the width and the diameter. To get the width, hold the wheel upright and measure one side of the wheel to the other, including the top plate. To get the diameter, lay the wheel flat on its side and measure it from one side of the other, without the metal attachments.

Are casters standard size?
