Square Footage Calculator

Add any number of areas — rectangles, circles, or triangles in feet & inches — to get exact total square footage, unit conversions, and material cost, with a downloadable PDF report.

Measure each area at its widest points and break odd layouts into separate rectangles, circles, or triangles. Estimates are for planning only — confirm final quantities with your supplier before buying material.
