What else matters here
A hundred and forty four square feet is a square of a square: twelve by twelve feet, which is also one hundred and forty four square feet and sixteen square yards exactly. The round numbers in every unit are why this size turns up in so many worked examples.
It is the size of a typical main bedroom in an older house, a small dining room, or a single car garage bay that is tighter than it should be. For materials it is convenient: twelve foot flooring, twelve foot drywall and twelve foot carpet all cross the room in one piece.
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.
