What else matters here
A hundred and eighty square feet, and a good dining room, which is a room sized by one measurement rather than by area.
The measurement is the pull back. A chair needs about 36 inches behind it to slide out and be sat in, and 44 inches if somebody has to walk behind a seated guest. So a table 42 inches wide and 72 inches long wants at least 114 by 144 inches of clear floor, which is 9 feet 6 by 12 feet. A 12 by 15 room clears that with room for a sideboard on one wall, and a 10 by 12 room does not, whatever the area says.
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.
