Flooring Calculator
Estimate flooring in square feet and boxes with waste included.
Use the flooring calculator to estimate the square footage and number of boxes required for a room or whole house. Multiply the room’s length by its width, include a 10% waste allowance, and divide the total by the manufacturer’s stated box coverage to calculate how many boxes you need.
