How to Use the Siding Calculator

The Siding Calculator is a tool designed to help you determine the amount of siding material needed for a building project. Follow the steps below to input your data and calculate the required siding area efficiently.

Step 1: Gather Your Measurements

  • Wall Height: Measure the height of the wall in feet. Ensure your measurement is within the range of 1 to 100 feet.
  • Wall Width: Measure the width of the wall in feet, making sure it falls between 1 and 1000 feet.
  • Number of Windows: Count the total number of windows on the wall.
  • Average Window Height: Measure or estimate the average height of the windows in feet. This should be between 0 and 20 feet.
  • Average Window Width: Similarly, measure or estimate the average width of the windows, ensuring it is also between 0 and 20 feet.
  • Number of Doors: Count the total number of doors present on the wall.
  • Average Door Height: Measure the average height of the doors in feet. Ensure it is within the range of 0 to 20 feet.
  • Average Door Width: Measure the average width of the doors, keeping within the same height range.

Step 2: Choose Your Siding Type

Select the type of siding material you are planning to use. The options are:

  • Vinyl Siding
  • Wood Siding
  • Fiber Cement Siding
  • Metal Siding

Step 3: Enter the Waste Percentage

Enter a percentage to account for material waste. This percentage should be a number between 0 and 100. This figure helps ensure you have enough material to cover any potential waste during installation.

Step 4: Calculate the Results

Once you have entered all your inputs, the calculator will automatically compute the following areas:

  • Total Wall Area: This is calculated as the product of the wall height and width.
  • Total Window Area: This is the total window area calculated by multiplying the number of windows by the average window height and width.
  • Total Door Area: Calculated by multiplying the number of doors by the average door height and width.
  • Net Siding Area Required: The net siding area is determined by subtracting the total window and door areas from the total wall area, then adjusting for your waste percentage.

The results will help you understand the amount of material necessary to cover the net siding area, ensuring efficient planning and utilization.
