Exterior Paint Calculator

Calculate Your Exterior Paint Needs with Precision

Planning an exterior painting project can feel overwhelming—especially when you're trying to figure out how many gallons to buy. Too little paint means emergency runs to the store and mismatched batches; too much means wasted money and storage headaches. This Exterior Paint Calculator helps homeowners, contractors, and property managers estimate paint quantities with accuracy, taking into account your home's siding material, architectural details, and surface texture.

Whether you're refreshing a single-story cottage or tackling a multi-level Victorian with complex trim, this calculator considers all the variables that impact coverage: the type of siding (wood, vinyl, stucco, brick), the condition and texture of surfaces, the number of doors, windows, shutters, and trim elements, and even whether you're changing colors or applying primer.

Built with Paperform, this template transforms a complex calculation into a simple, guided experience. Instead of juggling spreadsheets or outdated formulas, you answer a series of clear questions and receive an instant, personalized estimate—complete with paint quantities, recommended products, and estimated project costs. It's perfect for painting contractors offering instant quotes, hardware and paint stores providing value-added customer service, or DIY homeowners planning a weekend project.

With Paperform's calculation engine, the form updates totals in real time as you adjust your inputs. Conditional logic means you only see questions relevant to your project, and the results page can be customized to include product recommendations, links to purchase, or even an option to schedule a professional consultation. You can embed the calculator on your website, share it on social media, or send it directly to customers—and every submission is logged automatically for follow-up.
