How to Calculate Plywood Sheets
Formula
A standard 4×8 sheet of plywood covers 32 square feet. Divide your total area (with waste factor) by 32 to determine how many sheets you need.
Common plywood thicknesses include 1/4, 3/8, 1/2, 5/8, and 3/4 inch. Thicker sheets cost more but provide greater structural strength.
Common use cases:
- Subfloor installation
- Roof sheathing
- Wall sheathing and shelving
