How much paint do you need to paint a room?

How many liters of paint do you really need for walls, ceilings or entire rooms? This guide shows you how to calculate surface area, coats and paint coverage – clearly and simply.
Good to know: Always plan for two coats and an additional buffer of about 10% when painting highly absorbent or uneven walls.

FAQ

How do I calculate the wall area?
Multiply the height by the width of each wall and add all areas together to get the total wall area.
Do I need to subtract doors and windows?
Yes, for a more accurate result. Our calculator automatically helps you with this.
How many coats should I apply?
One coat is usually sufficient, but for darker walls or low-coverage paints, we recommend two coats.
Which paint coverage should I choose?
High-quality paints typically cover around 8 m² per liter. For cheaper or very light paints, select ‚Medium‘ or ‚Low‘.
How can I avoid paint wastage?
Stir the paint thoroughly and use high-quality rollers for an even coat.
