Board Sizing

The tables below are a reference for all common lumber / shelf board sizes. Both standard lumber sizes & white melamine shelving sizes are shown. All of the tabulated sizes are readily available at most home center stores. 3/4″ plywood is also an economical choice for wide shelving. Most home center stores will rip a sheet of plywood at no or minimal charge. Note that all shelf hanger widths are actually 1/8″ wider than their labeled width. This is the inside measured dimension of the shelf hanger.
