# How To Calculate Exterior Square Footage Of The Gable?

Measure from the bottom of roof/top of your home’s side to the peak of your roof. Write down the calculation, then divide it by 2. Multiply this number by the width of your home (#2 in the section above). This is the square footage of your gable and should be added to your original home area number.

Measure the width of the gable and the height of the gable, from the base of the triangle to the peak. Then multiply the width and height, just like you would to find the area of a rectangle. Finally, divide the area in half to get the final square footage. Divide by 100 to get the number of squares.

### How do you find the square footage of a gable?

Calculate the area of the gable using the formula: gable area = width x (height / 2). Using the example width of 25 feet and gable height of 10 feet, the surface area of the gable is 125 square feet: 25 x (10/2) = 125.

### How do you calculate siding coverage?

To find the number of squares of siding needed for an installation, measure each walls width and height in feet. Multiply the width and height to get the area of the wall in square feet. Divide the square footage by 100 to get the number of squares needed for the wall.
