Hardwood Flooring Calculator

Calculate how much hardwood flooring to order. Hardwood typically uses a 15 percent waste allowance for cuts, defects, and grain matching.

Hardwood Needed
— sq ft
Includes waste.

Usage Tip

Order all the wood from one batch so color and grain match, and let it acclimate in the room for several days before installing.

THE MATH
order = area × (1 + waste ÷ 100)
linear feet = order × 12 ÷ board width
Solid and engineered hardwood is sold by area but installed as long boards. It needs a higher waste allowance for defects, end trim, and grain matching.
Enter the floor area, the board face width in inches, and a waste percentage (15 percent is typical for hardwood).
Linear feet estimates the total run of boards you will lay.
