How to Calculate:
How to Measure Square Feet Coverage:
To calculate the square footage of an area, measure the length (L) multiplied
by the width (W) or height (H). This will give you the square footage needed
to cover the area. Remember if you are doing walls to include every all walls
in your calculations.
To figure the square footage of a Gable (the triangle wall area that meets the
roof line), measure the length (L) multiplied by the height (H) at the highest
point, then multiply by .60
Add all coverage areas together for your actual square footage required.
How to Figure Allowances:
You have to allow a waste factor for cutting, fitting and the occasional miss-cut.
Many times customers will fail to allow for doors, windows etc. We typically
figure in 15% to 20% for this allowance.
How to Convert Square Foot to Linear Foot:
Using 4” x 300%
Using 6” x 200%
Using 8” x 150%
Using 10” x 120%
Using 12” is the Same.
This will give you the linear footage need to cover the area. Don’t forget
to calculate for waste.
