What else matters here
Three hundred and twenty square feet is a large living room, a one bay shop, a single car garage with room to work, or a substantial deck. It is also almost exactly the size of a standard American one car garage plus a little.
At this size a floor is no longer one piece of anything. Sheet goods, carpet and underlayment all come in at 12 feet or less, so plan the seams and the direction before ordering rather than after. Running planks along the 20 foot dimension makes the room read longer; running them across makes it read wider.
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.
