Square footage is the area of a floor or surface in square feet. For a rectangular room, multiply length by width: 30 ft × 20 ft = 600 sq ft. Measure wall to wall at floor level and round up slightly.
Divide L-shaped or irregular spaces into rectangles, triangles, circles or trapezoids, calculate each with the matching section and add them. Subtract areas you will not cover, such as built-in cabinets.
Flooring, tile, carpet, paint and sod are priced per square foot or yard. Add 5–10% for waste and cutting, more for diagonal tile patterns. Enter a price to see the total cost.
Worked example: 600 sq ft of flooring at $3.50 per square foot costs $2,100 before waste.
How many square feet in a square yard? 9.
How many square feet in an acre? 43,560.
Does a home's listed square footage include garages? Usually not; it counts finished, heated living space.
