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 six square feet. This is the size where somebody usually asks what it takes to heat and cool, and the honest answer is that area alone does not settle it.

The rough rule of thumb, 20 BTU per square foot, puts this room at around 4,000 BTU, roughly a third of a ton. The rule is a starting point and nothing more. Ceiling height turns area into volume, and a vaulted ceiling can add half again. Window area, orientation, insulation level, air leakage, the climate zone and how many people use the room all move the answer, which is why a proper load calculation exists and why an oversized system that short cycles leaves a room clammy rather than comfortable.

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.

Questions people ask

How many square feet is a 14x14 room?

196 square feet, which is 21.78 square yards and 18.21 square meters.

What size air conditioner for a 14x14 room?

The rule of thumb is about 20 BTU per square foot, so around 4,000 BTU. Treat it as a starting point, because ceiling height, windows and insulation move it a long way.

Is bigger better when sizing HVAC?

No. An oversized system reaches temperature fast, shuts off before it has removed the humidity, and leaves the room cold and clammy.
