Square Footage Calculator
Add up the area of several rooms.
Measuring a space
Measure each room’s length and width in feet, and the calculator multiplies and adds. For L-shaped rooms, split them into rectangles and enter each part as a separate room.
Example
With the starting values shown (Room 1 length 14 ft; Room 1 width 12 ft; Room 2 length 12 ft; Room 2 width 10 ft; Room 3 length 10 ft; Room 3 width 10 ft), Total area comes out as 436. Other results include in square metres: 40.5; in square yards: 48.4.
Real estate listings follow their own measuring rules (for example whether walls and stairs are included), so listed floor areas may differ from your own measurements.
