How much paint will I need? This is a question that will save you a lot of money and time if it’s answered correctly!

In this post, we’ve tried our best to break it down for you so you can manage your expenses without a worry. Whether it’s for an entire home or just one room we’ve divided the number of coats and litres of paint you will need into easy tables so you can get a rough estimate in just one glance!

All you have to do is measure your area and see how much paint you will need from the tables. As you can see, the tables related to an entire home and separate rooms are different. It’s important to know that although this will help you get a close idea of your expenses, each project will differ a little depending on the design and conditions.

How much paint will I need for the walls and ceilings of a room?

Walls and ceilings need the highest amount of paint and nowadays acrylic paints are the most popular choice for them. In the table below, you can see how much paint per square meter you will need in liters for each room. This can be for a room in your home or even a workspace. The numbers in the table below are for walls that are either newly built or don’t have a clean polish from before. These types of walls will most likely also need patching and sanding. As we’ve mentioned in previous posts, they will require one layer of primer and two layers of the top coat. For a detailed explanation of this process see House painting in Australia. (House painting in Australia wasn’t linked)

Paint needed for new walls and ceilings 3 coats

Room Area in square meters / First paint Wall Primer (Liter) Walls (Liter) Ceiling (Liter)
1 coat 2 coats 2 coats
4 2 3 1
6 2 4 1

50 5 8 7
100 7 12 14
200 12 17 26

The following table is for walls that have previous paint and are being repainted. In this case, we recommend two coats of the main paint and no undercoat. Although, as we said before, this could change from project to project.

In some cases, the previous paint has been done so professionally and clean that you can get the same lasting result by just applying one coat of new paint. Some may think that one coat of paint will take half the amount of two but that isn’t the case. Our specialists have put this table together that shows more accurate numbers if you’re just going for one coat.

How much paint will I need for the walls and ceilings of my home?

If you’re planning on painting your entire home, we have good news for you! With the help of this table, you won’t need to go around measuring each room separately. You’ll only need to know the area of the actual house and the table will do the rest of the work for you. The first table is for surfaces that aren’t in the best condition or are being painted for the first time. If this is the case for you, one layer of undercoat and two layers of paint is recommended.

Paint needed for new walls and ceilings of a house 3 coats

House Area in square meters / First paint Wall Primer (Liter) Walls (L) Ceiling (L)
1 coat 2 coats 2 coats
50 7 17 8
75 10 22 10
100 15 24 13
125 17 28 16
150 21 33 20
175 24 38 22
200 26 50 25
300 32 49 40
400 42 65 53
500 50 80 65

The next two tables are for homes that have been painted before and are being repainted. The first table is for walls that need two coats of paint and the second is for the walls that only need one. We only recommend going for a single coat when your painter has seen the walls and decided that the previous paint was applied good enough for this to happen. You will find that most of the time two coats is the better choice.

Once again you should remember that these are for general cases and each project may differ a little. We recommend you also talk to a professional painter as costs can quickly get out of hand when you don’t know how much resources you need!

Good luck painting!
