Approximate Square Footage Of An Attic

Multiply step 1 and step 2 together to get the area of the attic floor.

Approximate square footage of an attic.

Assume for a moment that a house at 1800 sq. Covered enclosed porches can only be included if they are heated using the same system as the rest of the house. Using the aggregate area of these simple shapes can yield a more accurate roof area to be used with the roofing. Of living space measures 40 by 45 at the exterior.

One might then assume that the floor of the attic might approximate those same measurements. Let owens corning roofing help you calculate exactly how much ventilation you will need for a healthy and balanced attic with our 4 step ventilation calculator. The bedroom in the finished attic has 7 ft ceiling and is 220 square feet. Always have a balanced ventilation system.

The calculator cannot account for complex shapes based on a measurement of square footage alone. So just 1 inch of the 6 ft wide closet is 7 ft tall. For example if your length is 40 feet and your width is 20 feet then 40 20 800 square feet. For example if the base is 12 feet and the height is 10 feet the square footage is 6 x 10 60 feet.

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. Enter square footage calculate or enter the square footage of the attic or area to be vented. 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. 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.

Obviously issues such as gables dormers styles of roofing ac and electrical installations etc. The closet adjoining the room has a 7 ft tall ceiling center that dives down to 5 ft tall walls. 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. If the foundation measured 50 x 30 the foundation and footprint of the attic will be 50 x 30 1500 sq ft.

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. 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.
