What it means

A 12×12 room is 144 square feet. Square footage is length × width, so 12 ft × 12 ft = 144 sq ft. In metric that's about 13.38 square meters, and it's 16 square yards. The calculator above is pre-filled with 12 × 12 — change the numbers for any other size.

Formula & guide

How it's calculated

Square footage is an area, found by multiplying the two side lengths in feet. For a rectangular room, that's simply length times width.

1Measure the two sides in feet — here they are 12 ft and 12 ft.
2Multiply them: 12 × 12 = 144 square feet.
3To get square meters, multiply by 0.0929 → about 13.38 sq m.
4To get square yards, divide by 9 → 16 sq yd.

Worked example

Accuracy & assumptions

Assumes a rectangular room measured wall to wall in feet.
Measure to the inside of the walls at floor level for usable area.
For an L-shaped or irregular space, split it into rectangles and add each area.
Order flooring with a 5–10% waste factor on top of the raw area.
