How to Estimate Total Square Footage

You will need a tape measure and some simple calculations for total square footage.

For a rough estimate, you should be able to divide your siding into squares, rectangles and triangles

Squares and rectangles use the simple formula: square footage = height x length

Triangles use the formula: square footage = (height x length)/1.5


Remember to subtract the window areas

Squares & Rectangles


square footage = HxL
This works for any square or rectangle shape



square footage = HxL/1.5
The area of any triangular shape is the height times the length divided by 1.5
