Square Footage Calculator
Work out the square footage of a room or area from its dimensions.
Measuring an area
Square footage is the area of a space, the figure behind buying flooring, paint, tiles and turf, and quoting property sizes. This works it out from the dimensions, including for rooms that are not simple rectangles, so you have the number every area-based purchase depends on.
Enter the dimensions to see the square footage.
Handling awkward shapes
Simple rectangular rooms are easy; real spaces often are not, with alcoves, bays and L-shapes. The reliable approach is to break an irregular room into rectangles, work out each, and add them up — and to subtract areas you are not covering, like a kitchen island's footprint when flooring around it. Because so many purchases scale directly from square footage, an error here multiplies into buying too much or too little of everything.
Square Footage Calculator FAQ
How do I measure an irregular room?
Break it into rectangles, calculate each, and add them together — and subtract areas you are not covering, like a fixed island.
Why does getting square footage right matter?
Because flooring, paint, tiles and turf all scale from it, so an error multiplies into buying too much or too little of everything.
