Before you call up home painters, there are many decisions you’ll need to make. You’ll need to determine which colours you’ll want in each room of your home. You’ll need to determine which brand of paint you’ll want to purchase. And you should also determine how much paint you’ll need.
Curious to find out how many gallons of paint you’ll need? Follow this easy 5-step process.
1. Measure the Room
The first step to calculating how much paint you’ll need for your project is to measure the room to be painted. You can do this by determining the surface area of the room without including the ceiling or floor. First, measure the walls you want to paint, both from wall to wall and from floor to ceiling. Then, add up all the width measurements of the walls you want to paint. Multiply this number by the height of the room. This will give you the square metre size of the room to be painted.

2. Account for the Doors and Windows
You already discounted the measurements for the ceiling and the floor. Now you need to do the same with the windows and doors, which you, of course, will not be painting. All you need to do to discount the doors from your calculations is to subtract approximately 1.85 square metres for every door from the square metre number you calculated in step one. Windows, on the other hand, vary widely in sizes, so to account for them, you’ll need to measure their square metre measurements then subtracting the number you get from your initial calculation.
3. Consider the Paint You’ll Purchase
The surface area of the room you’ll be painting isn’t the only consideration when it comes to how much paint you should buy. You also need to factor in the type and the viscosity of the paint you want to use. Generally speaking, a 4-litre container of paint will enable you to paint a single coat of approximately 32 square metres.
4. Determine the Number of Coats You’ll Require
Many homeowners choose to continuously paint over the walls until the old paint colour is no longer visible. However, professional painters typically advise them to use a primer coat in order to create a blank canvas on the walls for the new paint. They may also use a tint layer to bring out the vibrancy of the paint colours.
The best way to determine how many coats you’ll need to account for is to use a tester pot of your paint and colour of choice on a small area on your wall. This will enable you to tell how well the paint holds up before you end up purchasing half a dozen containers. You may decide to go with a higher-quality paint that requires fewer coats rather than purchasing a lower-cost paint that requires several coats.
5. Complete the Calculations
Finally, with the surface area of the room and the number of coats you’ll need for your paint of choice, you can finalize your calculations by dividing the surface area by the square-metre capacity of the paint cans you’ll purchase. This will vary depending on the size of the paint cans.
