What else matters here
A hundred and twenty one square feet. Odd numbered room sizes look like a mistake and are usually the truth, because a room is drawn to framing and lived in to drywall.
A wall framed with 2 by 4 studs and half inch board on both sides is about 4.5 inches thick, so a run of rooms laid out on a 12 foot grid comes out closer to 11 feet 7 inches inside. Measure to the face of the drywall, at the floor, on both ends of the wall, because a room that is 11 feet 2 inches at one end and 11 feet 5 inches at the other is normal and the flooring has to cover the larger number.
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.
Questions people ask
How many square feet is an 11x11 room?
121 square feet, which is 13.44 square yards and 11.24 square meters.
Why are room dimensions not round numbers?
Plans are drawn to the framing and rooms are measured inside the drywall. A wall eats about 4.5 inches, so a 12 foot bay becomes an 11 foot 7 inch room.
Where should I measure a room from?
From the face of the drywall, at floor level, and at both ends of each wall. Old houses are rarely square and the flooring has to fit the widest point.
