Siding Lineal Feet Calculator


This siding calculator will calculate the lineal length of siding in feet, needed to cover a wall and the square feet of the wall.

  1. Siding width and overlap need to be entered in inches. (decimal format) eg an 8 1/4" board with 1 1/4" overlap = 8.25 for width, 1.25 for overlap.
  2. Wall length in feet
  3. Wall height in feet
  4. Add the combined square feet of Windows and Doors as required for your wall
