Finally, you decided to bite the bullet and start your very first DIY painting project for your home. You’ve read up on how to prepare the tools, prepare the work area and surface, how to choose the paint color, what kind of finish you want, and where to go to buy it. But how do you estimate the amount of paint you would need?

There are three ways you can do that.

Boysen Paint Calculator

1.   Boysen App

How Do You Estimate the Amount of Paint You Would Need?

If you’re a digital native, you could always use the Boysen App to calculate for you. Click this link to find out the step-by-step instructions on the download and use of the app.

2.   Paint Calculator

A second option would be to use the paint calculator available in the Boysen website. 

How Do You Estimate the Amount of Paint You Would Need?

What’s great about the first two methods is that the paint calculator will give you the paint system that you will be using. 

It will ask you the following:

– the kind of surface you will be painting
– the surface type, i.e. whether it’s interior or exterior walls, and whether it’s plain or texture
– the surface condition, whether it’s new painting or repainting
– the paint type, or the different Boysen paint brands
– the sqm area of the wall

You will not only be given the number of liters of paint that you will need but you will also get the other products that come with the paint system such as putty, neutralizer and primer. 

3.   The Manual Way

If you want to check your paint calculations, you can use the manual way, using the mano-mano formula:

((height x width) / coverage)) x number of coats

Sample Calculation of a Wall

Let’s say your ceiling height is 5 meters and the width of the wall is 10 meters. if you want to use Boysen Permacoat Latex to paint your concrete wall, you will see from the product description that the product coverage is 25 square meters. Assume further that you will paint 2 coats. 

((5 meters x 10 meters) / 25 square meters)) x 2 coats
= (50 / 25) gallons x 2 coats
= 2 gallons x 2 coats
= 4 gallons

This means that for one coat, you would need 2 gallons/coat. But if you want to make two coats, then you would be needing 4 gallons for the whole DIY project. 

Since 1 gallon = 4 liters, you will be needing 16 liters to complete your project, 

4 gallons x 4 liters = 16 liters

The Boysen paint packaging available are 1-liter, 4-liter and 16-liter cans. It is best to buy all the paint you need for a room before you start your DIY project. This is to make sure that the paint color is consistent for the whole area you’re working on!

If you have any questions about using the formula, you can have your calculations checked in a Mix & Match Station in a home depot close to you before you buy your paint.
