Sheets Needed
— 4×8 sheets
Rounded up.

Usage Tip

Lay out your cuts on paper first; smart nesting often saves a full sheet on cabinet and built-in jobs.

THE MATH
sheets = round up( area × (1 + waste ÷ 100) ÷ 32 )
Each 4×8 sheet covers 32 square feet
Plywood comes in 4-foot by 8-foot sheets, each covering 32 square feet. Sheet count is the project area divided by 32, plus a waste allowance for cuts.
Enter the project area and a waste percentage (10 percent is typical).
The result rounds up to whole sheets.
