How it works
Calculate how much paint you need for your walls from surface area, product coverage and number of coats.
Frequently asked questions
How much paint do I need?
Required paint is surface area times coats divided by product coverage.
Should I subtract doors and windows?
Yes, subtracting large openings improves the estimate.
Why might I need two coats?
The number of coats depends on the colour, surface and product coverage.
