Then multiply by 1 5 and you ll have enough siding to cover the two sides of the dormer.
How to measure for exterior siding.
Start by measuring the height and width of each wall of the building.
If you re also applying siding to your gable you ll want to measure the square footage of this as well.
Add up all of your square footage measurements to get the total and divide by 100 to determine the number of siding squares you will need to purchase.
Measure gables dormers and any other areas not included in the sides.
A square is a unit that covers 100 square feet.
Measure the height and width of each side.
Divide the total by 100 to find the number of squares of vinyl siding to order.
Multiply height by width to get that side s surface area in square feet.
H x w x 0 75 number of squares to cover your gables.
Please enter side s surface area.
Multiply each length and height measurement to find the square footage of each wall then add them together to find the total square footage.
Height times width and then multiply by 0 75 to account for the angle.
If the gable is hard to reach try measuring the height of the siding profile then multiply that number by the number of courses on the wall section.
In order to calculate the siding needed for gables measure the height and width of one then multiply that number by 75.
Add side measurements and enter them here.
However for all siding options siding is measured in squares when estimating siding materials.
Write down the calculation then divide it by 2.
