How much clearance does a mobile pedestal need under a desk?

A mobile pedestal needs a minimum of 1"–2" clearance between its top surface and the underside of the desk surface above to roll freely in and out. Standard commercial desks have 24"–28" of clear knee space height, and standard mobile pedestals are 22"–27" tall — so there is typically 1"–6" of clearance depending on the combination. Measure your desk's clear height before purchasing to ensure the pedestal will fit. Also account for any cable trays, power strips, or other undersurface accessories that may reduce the effective clearance.
