Calculating the Exterior Surface Area of Your 1600 Sq Ft House: Understanding How to Measure Your Home's Exterior Surface Area

Quick Summary

- The total exterior surface area equals the sum of the wall area and the roof area.

- For a 40 ft by 40 ft single-story house with 10 ft wall height and 144 ft perimeter, the wall area is 1440 sq ft.

- The roof area is typically equal to the floor area for a flat roof.

Calculating the exterior surface area of your 1600 sq ft house involves several steps. First, it's essential to understand that the total square footage typically refers to the interior space. To find the exterior surface area, we need to consider the dimensions of the house's walls, roof, and any additional structures such as garages or porches.

Most homes are rectangular or square in shape, so let's assume your house is a single-story rectangle for simplicity. The formula for the perimeter (P) of a rectangle is P = 2(length + width). To find the length and width, you can use the formula for area (A = length x width) to determine the dimensions based on your total square footage.

Calculating the Dimensions:

If your house is 1600 sq ft, and assuming it is rectangular, you might have variations like 40 ft by 40 ft (for a square) or 50 ft by 32 ft. Once you determine the dimensions, you can calculate the perimeter.

Calculating the Total Exterior Surface Area:

For a single-story home, the exterior surface area can be calculated by adding the wall surface area and the roof surface area. The wall area can be determined by multiplying the perimeter by the height of the walls. For instance, if the wall height is 10 ft, and the perimeter is 144 ft (for a 40 ft by 40 ft house), the wall area would be 144 ft x 10 ft = 1440 sq ft. The roof area is typically the same as the floor area for a flat roof or can be calculated using specific formulas for pitched roofs.

Conclusion:

In summary, the total exterior surface area of your house would include the walls' area and the roof area. Remember to include any additional structures in your calculations. Taking accurate measurements and considering the house's shape can help you achieve a more precise calculation.
