Project Material Calculator
Free material estimates for home improvement projects
Free paint calculators for interior walls, ceilings, exterior siding, primer, wall area, coats, coverage, waste allowance, and estimated material cost.
Hi Product Hunt! 👋
I built Project Material Calculator after noticing how difficult it can be to get a clear answer to a simple home improvement question: “How much material should I actually buy?”
Many calculators provide only a final number, without explaining the assumptions behind it. I wanted to create something more transparent and practical.
The site includes free calculators for paint, primer, spray paint, concrete, drywall, flooring, tile, wallpaper, caulk, deck stain, and other common projects. Users can adjust dimensions, coverage rates, coats, waste allowances, package sizes, and prices. Each calculator shows the formula and turns the result into a purchase-ready estimate.
The tools work directly in the browser, require no account, and support both metric and imperial measurements across multiple languages.
I’m continuing to improve the formulas, real-world examples, and project coverage. I’d especially appreciate feedback on:
• Which calculator would be most useful for your next project?
• Are any inputs or results unclear?
• What material or project should I add next?
Thanks for taking a look!
