Every material calculator on the site starts here, which is why this one also gives square yards and square meters. Odd shapes get broken into rectangles and added on, because a rectangle is the only shape a tape measure is honest about.

What else matters here

A hundred and ninety two square feet is a generous main bedroom, a decent family room, or the most common shed and deck footprint in the country. It is also close to the largest room that a single twelve foot wide floor covering will cross without a seam.

The perimeter is 56 feet, which is what you need for baseboard and for paint. Note that the perimeter of a 12 by 16 is barely larger than that of a 14 by 14, which has the same floor area, but the square room needs less trim and less paint. Room shape costs money in a way floor area does not show.

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.
