1. What is the House Paint Calculator?

The House Paint Calculator estimates the amount of Sherwin Williams paint needed based on house area, paint coverage per gallon, and number of coats required. It helps homeowners and contractors accurately plan paint purchases.

2. How Does the Calculator Work?

The calculator uses the paint formula:

Where:

• \( A_{\text{house}} \) — Total house area to be painted (square feet)
• \( C \) — Paint coverage per gallon (square feet per gallon)
• \( N \) — Number of coats required (unitless)

Explanation: The formula calculates total paint needed by dividing the house area by the coverage per gallon, then multiplying by the number of coats.

3. Importance of Paint Calculation

Details: Accurate paint calculation prevents over-purchasing or under-purchasing, saves money, ensures project completion, and helps with proper paint mixing for consistent color.
