How Much Paint You Need for a Wall
Paint (L) = wall area (m2) x coverage rate. For two coats use about 0.13 L/m2: a 30 m2 wall needs 30 x 0.13 = about 3.9 L.

Frequently asked questions
How much paint for a 30 m2 wall?
About 3.9 L for two coats: 30 m2 x 0.13 L/m2.
Why two coats?
Two coats give even color and coverage; the 0.13 L/m2 figure already combines both coats.
Does surface texture matter?
Yes. Rough or porous surfaces absorb more paint, so add a margin above this estimate.
