People also ask, what thickness plywood should I use for flooring?
Thickness of Plywood The thickness of your plywood subfloor depends on the joist spans. The National Wood Flooring Association recommends a minimum plywood panel thickness of 7/8-inch for joist spans of 19.2 to 24 inches, and a minimum plywood panel thickness of 5/8-inch for joist spans of 16 inches or less.
Beside above, how thick should a subfloor be? Typically made of plywood or OSB and ranging in thickness from 19/32" to 1 1/8" thick, the subfloor is truly structural, second only to joists in this respect.
