1. What is the Vinyl Siding Calculator?

The Vinyl Siding Calculator estimates the number of siding squares needed for your home based on total wall area minus openings. Home Depot vinyl siding is typically sold in squares (100 square feet per square).

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( house\_sqft \) — Total exterior wall area in square feet
• \( openings \) — Area of windows and doors in square feet
• 100 — Conversion factor (1 square = 100 sq ft)

Explanation: The equation calculates net wall area by subtracting openings, then converts to siding squares.

3. Importance of Accurate Siding Calculation

Details: Proper calculation helps avoid material shortages or excess purchases, saving time and money on your siding project.
