| Pallet Rack Measuring and Sizing Guides
In addition to showing
the correct way to measure pallet rack, the diagram below
shows the two basic components of
pallet rack: 1) an upright (also called a frame), and 2)
a beam. For a more detailed breakdown of rack components,

A Guide to Sizing Your Rack Order
This guide will help you determine the required heights
and depths of the upright frames and the beam lengths and
capacities needed to meet your load requirements.
Rack Height
Rack Height is the height of the uprights/frames. Determine
by adding the following:
•
Height of pallet loads (including the pallet)
•
Height of beams
•
4” vertical clearance between top of load and bottom
of beam
•
Sum of above dimensions equals frame/upright height
• If pallet loads are stored on the top of the rack,
beam location should be at least 6” less than the fork
truck’s lift height.
• Also keep in mind ceiling height and the ceiling
clearance required by local codes.
Rack Depth
Rack depth is the depth of a single upright/frame. It depends
on the design and size of pallet used.
•
The front and back of the pallet should overhang approximately
3”. Example: a 48” deep pallet requires a 42” deep
frame. (3” overhang for both front and back.)
Beam Length
Beam length is the distance between a pair of uprights/frames
in each rack bay.
•
Required beam length is determined by adding the width of
pallet loads, plus 4” clearance between pallet loads,
plus 4” clearance between loads and each upright/frame.
Beam Capacity
Beam capacities are based on a pair of beams supporting an
evenly distributed load.
•
Determine the weight of each pallet load and multiply times
the number of loads per shelf. Example: a pallet load weighs
2000lbs and there are two pallets per shelf. A beam capacity
in excess of 4000lbs is required.
