Knowing how much paint to use can be a frustration to some artists. While it is best to mix more paint than needed for your project, mixing too much paint can be very time consuming and sometimes wasteful. When I first started learning about paint mixing, I watched so many videos that said “use about this much” or “just eyeball it”. These techniques of learning may work for some but I had a hard time feeling confident to start learning until I watched more to learn what “just eyeball it” really meant.
It’s time to take the guess work out of the mix!
I have created two calculators for you to use to help determine how much paint is needed for your project. These calculators are a FREE resource to assist you with your project. And, they are simple to use! You will enter the height and width of your square or rectangle surface (or diameter if using a circle surface), and the depth of the side of your surface. The calculators will give you the approximate ounces of paint you will need to complete your project!
Acrylic Paint Calculators:
Tips for using the calculators
- The calculations above are provided as approximate measurements needed of fluid paint to complete your project, including any base paint layers you start with.
- Fluid paint is defined as a combination of acrylic paint, water and pouring medium.
- If your surface does not have sides you wish to cover, please enter “0” in the “Depth” field.
- Different variables will alter these measurements such as paint consistency and the pouring technique used. If you use a thicker consistency of mixed paint, you will need to add between 5%-10% more paint to the calculated measurement.
QUICK GUIDE FOR COMMON SURFACE SIZES
For your convenience, I am also providing a chart that I use with some common canvas sizes. This chart uses the same formulas as the calculators above but it provides quicker AT GLANCE information for the flat surface. This chart does not include the side measurements of your surface, you will need to add that measurement in.
