Project Materials Calculator

Measure a project. Know what to buy. Project Materials Calculator turns room, wall, slab, and bed measurements into a clear purchase quantity — cartons, cans, sheets, bags, or yards — with the arithmetic and assumptions shown underneath so you can check them before you shop.

Six guided flows cover paint, flooring, tile, drywall, concrete slabs, and mulch/soil/gravel. Enter dimensions the way the tape reads — feet, inches, and fractions — set the coverage or yield printed on your actual product, adjust the waste allowance, and save several estimates under one named project. The purchase list groups matching materials, marks what's bought, and copies or shares as plain text.

Everything runs on your device: no account, works offline, and every result is a planning estimate to verify against your product label and project conditions — not a guarantee. Prices are the ones you enter — not retailer feeds.

Free: all six calculators, breakdowns, up to 5 active projects, and text sharing.
Pro: PDF/CSV export, reusable products, unlimited projects and no ads. One-time purchase; no subscription.
