Classic tool
Square Footage Calculator
Calculate square footage for rooms, flooring, yards, lots and simple layout projects.
Use this square footage calculator to measure the area of a room, floor plan, yard, lot or other simple space. It is useful when you need quick numbers for flooring, carpet, grass, paint coverage on flat sections, or real estate listings that rely on square footage as the main reference.
The tool supports rectangle, triangle and circle layouts. You can enter dimensions in feet, inches, yards, meters or centimeters, and it returns the base area in square feet along with quick conversions to square meters and square yards.
You can also add an extra waste percentage. That makes the result more practical for flooring, carpet, laminate and similar materials where you often buy a little more to cover cuts, fitting adjustments and normal installation loss.
Use clear inputs to get a more useful result.
