Questions people ask

How much paint do I need for a room?
Wall area = 2 × (length + width) × height, less doors and windows, + the ceiling if you paint it. Litres = area × coats ÷ the coverage printed on your paint tin.
Why do I have to enter the coverage?
It differs by paint brand, product and surface — use the figure on your tin.
Is my data uploaded?
No. Everything is worked out in your browser and the PDF is made on your device.
