Paint Calculator

Enter room sizes, doors and windows and see gallons of paint and primer to plan for.

These tools give planning-level estimates from typical values. They are not quotes, designs or engineering, and results depend on your actual home, materials, access, local rules and conditions. Only a visit can confirm what your home needs, and we give you a clear price before any work begins.

Questions

About this tool.

Is this exact?

No. It is a planning guide. Paint coverage varies by product and surface, and we confirm quantities in your quote.

How much does one gallon cover?

About three hundred and fifty square feet for one coat on a smooth wall. Rough surfaces use more.

Do I need primer?

On bare drywall, stains, repairs and big color changes, yes.
