Free Paint Calculator: Estimate Litres & Reduce Waste
Stop guessing how much paint you need. Whether you are refreshing a single room or decorating an entire property, our easy paint calculator gives you the exact volume required for walls, ceilings, and trim.
Most online calculators use generic numbers. Ours is different. We have pre-loaded the specific coverage rates for the UK’s leading trade paints, including Dulux Trade, Johnstone’s Trade, and Crown Trade. Simply enter your measurements, select your desired finish, and we’ll tell you exactly how much to buy.
