How to Use This Vinyl Siding Calculator
This calculator is designed to help you estimate the amount of vinyl siding you’ll need for your project.
Here’s a brief explanation of how to use it:
- Enter the Wall Length in feet.
- Enter the Wall Height in feet.
- Enter the number of Windows you have on the wall.
- Enter the number of Doors on the wall.
- Enter the Average Window Area in square feet.
- Enter the Average Door Area in square feet.
- Enter the Extra Material percentage to account for waste (typically around 10%).
Once you’ve entered all the required values, click the Calculate button to get the total amount of siding material needed in square feet.
How the Calculation Works
The calculator follows these steps to compute the result:
- Calculate the total area of your wall by multiplying the length by the height.
- Subtract the total area of the windows and doors from the total wall area to get the net wall area.
- Add a waste factor to the net wall area by multiplying it with the extra material percentage (converted to a factor).
- The result is the total siding material needed in square feet.
Limitations
This calculator provides an estimate based on the inputs you provide and assumes regular rectangular shape walls:
- It does not account for irregular wall shapes or additional architectural features.
- Averages an area for windows and doors which might not precisely match real-world dimensions.
- Additional framing or trim required is not included in the calculation.
Always consult with a professional for precise measurements and material requirements.
