To calculate the square footage of an 18x13 room, multiply the length by the width. So, 18 feet multiplied by 13 feet equals 234 square feet. Therefore, the room is 234 square feet in size.
To calculate the square footage of a room, multiply its length by its width. For a 9 x 12 room, the calculation is 9 feet multiplied by 12 feet, which equals 108 square feet. Therefore, the room is 108 sq ft in size.

measure the square footage of your house when you go to purchase your furnace. Then they can change that figure to BTU's.
Multiply the length times the width.

Square footage estimates on drywall are based on the square footage of wall and ceiling that need to be covered.
A general rule of thumb in estimating the size of furnace needed to heat a home is to find the square footage of the home, and multiply that by 45 BTU (British Thermal Unit). For a 3200 square foot home a furnace somewhere in the range of 144,000 BTU would be a reasonable estimation of the furnace size needed to heat the home. To find the most efficient furnace for any given home, however, it would be best to contact an HVAC professional who can perform a load-calculation.
The size of your house can be determined by measuring the square footage of the living space.
