Square Footage Calculator
Area in square feet and square meters.
The simplest calculator here: enter any rectangle's length and width in feet and get the area in square feet and square meters. Use it for rooms, gardens, plots, or comparing listings. It is the building block behind our paint, flooring, and tile calculators.
How it's calculated
Square feet = length × width in feet. Square meters = square feet × 0.09290304.
Frequently asked questions
How do you calculate square footage?
Multiply length by width. A room that is 10 ft long and 12 ft wide has an area of 120 square feet.
How do I convert square feet to square meters?
Multiply square feet by 0.0929. So 120 sq ft equals about 11.15 m² — our calculator shows both units side by side.
Is square footage the same as cubic feet?
No — square footage measures area (length × width). Cubic feet measure volume (length × width × height), which is a different number entirely.
