Find the area of a room or space in square feet, square meters, and square yards — useful for flooring, paint, carpet, and tile estimates.
Area = length × width, converted to a common unit (feet) first if the input is in inches, meters, or yards.
Square footage is the standard measurement for pricing flooring, paint, carpet, tile, and other materials that are sold by area rather than by length or volume.
Example: a 12 ft × 10 ft room has an area of 12 × 10 = 120 square feet.
| Room size | Square feet | Square meters |
|---|---|---|
| 10 ft × 10 ft | 100 | 9.29 |
| 12 ft × 15 ft | 180 | 16.72 |
| 20 ft × 20 ft | 400 | 37.16 |
How do I calculate square footage of a room? Multiply the room's length by its width, in feet, to get the area in square feet.
How do I convert square feet to square meters? Multiply the square-foot value by 0.092903 to convert it to square meters.
How do I calculate square footage for an irregularly shaped room? Split the room into rectangles, calculate the area of each separately, and add them together for the total square footage.
How much flooring or paint do I need based on square footage? Most material calculators use square footage directly, but it's common to add 10% extra to account for cuts, waste, and pattern matching.
Can I use this calculator for square yards? Yes — the result includes square yards alongside square feet and square meters, which is useful for carpet and turf that are often priced per square yard.
