Calculate floor area
Choose a rectangle, triangle or circle, enter dimensions in feet or inches, and set the number of equal areas. The calculator reports square footage, adds a configurable waste allowance and can estimate material cost per square foot.
For irregular rooms, divide the floor into simple shapes and add their areas. Measure carefully and confirm supplier recommendations for extra material.
