How many coats do I need?

Most craft painting needs 2 coats for even coverage. Dark colours over light surfaces or vice versa may need 3 coats. A primer coat can reduce the total paint needed.

Does surface texture affect coverage?

Yes. Rough or porous surfaces like bare wood or canvas absorb more paint and reduce coverage. Sealing or priming first helps paint go further.

How do I convert the result to pots?

Divide the total ml by the pot size. For example, if you need 150ml and pots are 59ml, you need 3 pots (150/59 = 2.5, rounded up).

How We Calculate This

The calculator converts your surface dimensions to square metres, then divides by the coverage rate (m² per litre) for your paint type.

This gives the volume per coat in ml, which is multiplied by the number of coats for the total.

Coverage rates vary: acrylic ~12 m²/L, chalk paint ~10 m²/L, spray paint ~6 m²/L.
