L Shaped Room Calculator

Many homes contain rooms that are shaped like an L rather than a perfect rectangle. If you need to know the area and perimeter of an L-shaped room for remodeling purposes, you can calculate these measures easily by hand or with the calculator on the left.

An L-shape has six sides, five concave corners, and one convex corner. For purposes of calculation, you only need to know the width and length of the outer part of the L, and the width and length of the inner part of the L.
