Hardie Siding Calculator: Estimate Costs & Materials

Our Hardie Siding Calculator helps you quickly estimate the amount of siding needed for your project.






How to Use the Hardie Siding Calculator

To use this calculator, fill in the following fields:

  • Length: The length of the wall in feet.
  • Height: The height of the wall in feet.
  • Total window area: The total area of all windows combined in square feet (optional).
  • Total door area: The total area of all doors combined in square feet (optional).
  • Wastage percentage: The expected wastage percentage (between 1% and 10%).

How It Calculates

The calculator computes the area of the wall by multiplying the length by the height. It then subtracts the total window and door area to get the net wall area requiring siding. Finally, it adds the specified wastage percentage to account for material wastage and provides the final required siding area.

Limitations

This calculator assumes a regular rectangular wall and does not account for complex shapes and features. The wastage percentage should be realistic, ideally between 1% to 10%. Always consult with a professional for precise siding requirements.
