How does this paint calculator work?

House painting means choosing the colors, measuring the place you need to paint and eventually starting to wonder how much paint do you need. This tool comes in handy in such situations and only requires you to enter basic information:

■ the dimensions of the room you want to paint;

■ the number of windows and doors;

■ the number of coats of paint you want to apply;

■ the coverage of the paint you are using.

Example of a calculation

In case you need to paint 75.35 square meters, for a number of 2 times. This means a total of 150.71 square meters and the tool will return that you need 12.56 liters of paint.

How to calculate how much paint you need

First of all you will need to calculate the surface on which you want to apply the paint. Don't forget about the ceiling! The paint calculator helps you do the math fast.

You only need to enter the length, width and height of the room you want to paint. From the resulting surface the calculator will subtract an average dimension for your selected number of doors and windows.

You will also need to decide how many coats of paint you want to apply. It is usual to apply two coats for better results and even consider using a primer.

In the paint coverage field you can choose from the average values. The spread rate of the paint depends on the surface irregularities, porosity and material loss when mixing.

The order in which you paint a room is commonly from top to bottom. So start with the ceiling, go down on the walls and then paint the windows, doors and trim.
