The standard thicknesses for plywood are 1 ¼, 1 1/8, ¾, 5/8, ½, 3/8, ¼, and 1/8 inches. The corresponding actual thicknesses are 1 ¼, 1 1/8, 23/32, 19/32, 15/32, 11/32, 1/4, and ⅛, respectively. This takes into the effect of sanding throughout the process of manufacturing the plywood for each of these sizes.12-Aug-2019
