What else matters here
One hundred and twenty square feet is the standard second bedroom in a great deal of American housing stock, and it is the size a 12 foot wide carpet roll covers in one piece with no seam. That is not a coincidence; broadloom comes 12 feet wide precisely because so many rooms are.
If the room is going to take carpet, orient the roll along the 12 foot dimension and the whole floor is one cut with no seam anywhere in it. Turn it the other way and you have a seam plus an offcut you cannot use.
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.
