About this calculator
L-shaped rooms split into two rectangles. Measure both legs of the L separately, then sum the areas. Watch the dimensions: the "width" of the smaller leg is the depth from the inside corner.
Frequently asked
L-shapes don't have a single L×W. Splitting into two rectangles is the cleanest method.
