Guessing paint quantities usually ends with a half-empty can, or a second trip to the shop. This free paint calculator works out exactly how much paint you need from your room measurements, so you buy the right number of cans the first time.
How to Use This Tool
- Measure your walls, length, width and ceiling height, and enter them above.
- Add your doors and windows so they are taken off the painted area.
- Choose your coats and paint coverage, then read your paint plan.
- Check the cans to buy and the estimated cost before you shop.
Why It Helps
Buying the right amount saves money and avoids waste. With the exact litres, cans and cost worked out in advance, you can budget properly and finish the job without running out halfway through a wall.
