How to measure square footage
Measure each room's length and width in feet at the longest points, then multiply the two numbers. For L-shaped rooms, split the space into two rectangles and enter each as its own row. The calculator adds every room and keeps a running total, so you can price flooring, paint, or an entire house listing. Measuring in inches? Divide by 12 first (e.g. 12'6" = 12.5 ft).
