Acrylic Pouring Paint Calculator

Free Online Tool for Fluid Artists

With this Acrylic Pouring Paint Calculator, you can quickly figure out how much paint needed for the size of the canvas that you have including the edges and round format canvases! This tool helps to minimize the waste of paint as well as prevents the uncovered corners when you mix not enough.

The calculation is now available in inches and centimeters.

NEW Acrylic Pouring Paint Calculator:

  • Rectangular  Canvas
  • Round Canvas

Entering Data:

1. Choose the shape (rectangular or round) and preferred measurement units (inches or centimeters)

2. Enter consistency of your paint pouring mixture: thin, medium, or thick. 

3. Enter dimensions of your canvas/panel (length & width or diameter for round shape)

4. Enter depth (thickness) or your canvas/panel. If you don’t want to cover the sides, leave that field empty or enter “0”. 


The calculated result includes the total amount of pouring mixture (paint, pouring medium and/or water) required to cover the canvas in ml or fluid oz.


I have designed this acrylic pouring paint calculator based on my personal experience and lots of experimenting with different formulas. Please note that these are approximate calculations, and many factors affect the amount of paint needed to cover the canvas (read factors below).

Factors Affecting the Amount Of Paint Needed

When Working With This Acrylic Pouring Calculator

Please keep in mind that the number calculated above is approximate, and you need to adjust depending on the technique that you are planning to do. If you are going to do a lot of tilting to stretch cells, rings, or any other elements, you would need more paint as you are going to lose some during the tilting. And if you are going to do very little to no tilting (like for swipe, straw blown flowers, or dutch pour), less paint mixture is needed.

If you prefer to apply the base layer first, you should decrease the total of your paint mixture by 30%-50% (depending on whether you prefer to leave any negative space or not).
