Square Footage Calculator
Square Footage Calculator
Enter the length and width of a room, yard, or any rectangular space to find its area — shown in square feet, square yards (how flooring and carpet are often priced), and square meters.
Flooring, carpet, and turf are frequently priced and sold by the square yard rather than the square foot, which is why this calculator converts automatically between the two — a 12×15 ft room works out to 180 square feet, or 20 square yards, a distinction that matters directly when comparing quotes from different flooring suppliers who may price in either unit. The unit-system selector lets you enter dimensions directly in either feet or meters, useful for international projects or simply matching whatever unit your building plans or measuring tools already use.
- Imperial formula: Area = Length × Width, in feet. Example: 12×15 ft = 180 sq ft = 20 sq yd.
- Metric formula: Area = Length × Width, in meters. Example: 4×5 m = 20 m².
- Switch units using the Unit System selector to enter dimensions directly in feet or meters.
Why do flooring stores quote prices per square yard?
Carpet and some flooring materials are manufactured and sold in rolls, and square yards is the traditional unit for that trade — divide square feet by 9 to convert.
How do I handle an L-shaped room?
Divide it into two rectangles, calculate the square footage of each separately, and add the two results together for the total.
