Empowering Homeowners & Contractors with Transparent Math

HousePaintCalc is an open, client-side material estimation engine built to eliminate guesswork from home improvement projects.

HousePaintCalc was built to solve a persistent frustration in renovation planning: traditional online calculators that are bloated with multi-step lead forms, hidden assumptions, and imprecise rules of thumb.

Our Core Standards

Citable Mathematical Standards: Every calculation is calibrated to established architectural coating standards (350–400 sq ft/gal or 8.6–9.8 m²/L per coat) with exact opening cutouts.
Instant In-Browser Execution: Zero latency, no signup walls, and no paywalls. All math runs instantly in your browser.
Privacy-First Architecture: Your room dimensions and project notes are never stored or sold to contractors.
Mobile-Optimized Interface: Designed for effortless use on a smartphone in the paint aisle or on the job site.

Expanding Material Estimators

Paint coverage calculation is the first step in our cluster of home improvement tools. We are actively expanding to include specialized calculators for concrete, tile, drywall, and lumber.
