What else matters here
A hundred and thirty two square feet for a plain rectangle. Very few real rooms are a plain rectangle, and the fix is simpler than people expect.
Split the floor into rectangles and add them. A room with a closet bumped out of one wall is one big rectangle plus one small one. An L shaped living and dining space is two rectangles that share a line. A bay window is a rectangle plus a triangle on each end, and for material ordering it is close enough to treat the bay as a rectangle at its deepest point. Run this calculator once per rectangle, or put the second piece into the extra area field.
What this calculator assumes
- Length times width, times how many areas are that size. For an L shaped room, split it into two rectangles and run this twice.
- Square yards are square feet divided by nine, which is how carpet is still quoted in much of the country.

132 square feet, which is 14.67 square yards and 12.26 square meters.
How do you measure an L shaped room?
Split it into two rectangles along a straight line, work out each one, and add them. That is exactly what the extra area field on this calculator is for.
Do I include closets in the square footage?
For flooring and paint, yes, if they are getting the same material. For a listing, a reach in closet is usually counted within the room it opens onto.
The square footage calculator takes any dimensions you like and hands back the same list.
