Ceiling Sheetrock Thickness Guide

What Thickness Sheetrock for Ceiling?

The thickness of sheetrock for a ceiling depends on the spacing of the ceiling joists. For joists spaced 16 inches or less apart, 1/2-inch thick sheetrock is adequate. For joists spaced 24 inches apart, 5/8-inch thick sheetrock is recommended to provide additional strength and rigidity.
