Dulux is one of the easiest paints to find in Canada (Canadian Tire and other PPG retailers). This Dulux paint calculator uses your room size plus the spread rate on Diamond, Lifemaster, or Ultra — the same gallon math, your can’s coverage.
Default 10% for touch-ups
Running out mid-wall means a second trip and a possible batch mismatch. 768 sq ft of two-coat coverage ÷ 400 = 1.9 gallons. Buy 2 of Diamond or Lifemaster for smooth primed 12×12 walls; buy 3 if you skipped primer on a colour change.
Weathershield and exterior products cover less per gallon — switch paint type in the calculator and read the exterior label, not the interior Diamond number.
Home Depot cans are usually Behr. Home Hardware is often Beauti-Tone. Lowe’s is often Valspar. Chart: Canadian paint coverage by brand.

Typically 2–3 gallons of interior latex for two coats. Diamond / Lifemaster often list ~400 sq ft per gallon on ideal walls. Canadian Tire staff cannot override a short can — round up in this calculator before you check out.
Both are PPG brands in Canada. Dulux is the national consumer name (Canadian Tire). Sico is especially strong in Quebec. Use the [Sico calculator](/sico-paint-calculator) when that is the label on the can.
Often yes. 37 m² per 3.78 L ≈ 400 sq ft/gallon. Convert before entering sq ft per gallon, or use the imperial line if the bilingual label shows both.
No. Independent tool, not affiliated with Dulux, PPG, or Canadian Tire.
