Approximate square footage of an attic.

Federal housing authority recommends a minimum of at least 1 square foot of attic ventilation evenly split between intake and exhaust for every 300 square feet of attic floor space. The area calculator can be used to calculate the area of a variety of simple shapes that together can comprise the area of the roof. For example if your length is 40 feet and your width is 20 feet then 40 20 800 square feet. Multiply step 1 and step 2 together to get the area of the attic floor.

Some people wonder if an attic can be included in the finished square footage of a home if there is a pull down ladder or existing stairway to the space. So just 1 inch of the 6 ft wide closet is 7 ft tall. Obviously issues such as gables dormers styles of roofing ac and electrical installations etc. One might then assume that the floor of the attic might approximate those same measurements.

Enter square footage calculate or enter the square footage of the attic or area to be vented. Might alter that. Step 5 add together the square footage values of the square rectangular and triangular floor areas to find the total square footage of your attic. The calculator cannot account for complex shapes based on a measurement of square footage alone.

For example if the base is 12 feet and the height is 10 feet the square footage is 6 x 10 60 feet. Always have a balanced ventilation system. If your home is a perfect two story with the second floor perfectly over the first floor you can usually measure the foundation of the home to get the approximate total of the attic. To be included in the square footage an attic would first need to meet the same criteria as any other space heating flooring ceiling and wall covering.

Finished attic square footage is included if an area has at least seven minimum feet of clearance. If the foundation measured 50 x 30 the foundation and footprint of the attic will be 50 x 30 1500 sq ft. Assume for a moment that a house at 1800 sq. The bedroom in the finished attic has 7 ft ceiling and is 220 square feet.

Garages pool houses guest houses or any rooms that require you to leave the finished area of the main house to gain access are not. The closet adjoining the room has a 7 ft tall ceiling center that dives down to 5 ft tall walls.
