About Paint Calculator

Paint Calculator helps homeowners and DIYers estimate how much paint to buy before heading to the store. Enter room dimensions and ceiling height, choose walls or ceiling, add coats and waste, and get gallon counts rounded up so you do not run short mid-project. We also publish short beginner notes on rollers, brushes, tape, and drop cloths — general DIY guidance, not a store or brand how-to.

Paint Calculator is independent. We are not affiliated with, endorsed by, or sponsored by Behr, Benjamin Moore, Sherwin-Williams, Cloverdale Paint, Dulux, Sico, Beauti-Tone, CIL, Valspar, or their parent companies. Brand names appear so you can match typical Canadian can labels. See our disclaimer.

The calculator runs entirely in your browser — no account, no uploads, no sales calls. Copy the shopping list and take it with you.
