Learn How to Measure a Siding Project

Its simple to measure your home for new siding. You'll need a tape measure and some paper to write your figures.

To estimate the amount of siding and accessories you'll need, follow the instructions below:

Rectangular Wall Surfaces:

Measure height (H) (excluding gables), measure width (W) (including windows and doors)

             W X H = Surface area 

 Triangular gable end surfaces

Measure height (H) at center (add 1' to allow for waste). Measure width (W)  and divide by half.  Repeat for remaining gables.

             H X 1/2 W = Surface area 

Add together surface area for all sides and gable ends for total surface square footage.
