How to use the Epoxy Calculator

Our epoxy calculator is easy to use!

Simply choose your epoxy formulation, enter your project dimensions, and we’ll let you know how much resin you’ll need to get the job done.

Including how many gallons, fluid ounces, or milliliters of epoxy you need!

If you’d rather do it yourself simply measure the length, width, and height of your pour area by inches, multiply them together (L x W x H), and finally – divide that number by 1.805.

This will give you the fluid ounces needed for your pour! We go into further detail on this below.

Round Project Epoxy Volume Calculator

Working on a less than square project? Don't worry—we've got your back!

Just measure the diameter of your pour area (in inches), determine how deep you plan to pour your epoxy, and select your formulation.

Easy as that! If you want to do it yourself, check out the details below:

For round or circular applications you will follow these steps:

  • First, measure the diameter of your substrate, and divide by 2 to get your radius. (Diameter / 2 = Radius)
  • In order to get your volume in cubic inches you will follow this formula: (radius squared) x pi (3.14159265) x (preferred depth of pour)
  • Finally, divide that number by 1.805 to convert the cubic inches to U.S. fluid ounces. (Cubic Inches / 1.805 = Fluid Ounces)
  • Bonus Tip: To convert ounces to gallons, you can divide by 128. (Fluid Ounces / 128 = Gallons)

Cubic Inches & Weight Ratio Calculators

These calculators help you determine the exact amount of epoxy resin needed for your project. Simply enter your measurements and select your formulation to get precise mixing ratios.

Our calculators work with all Superclear epoxy formulations including Liquid Glass Deep Pour, Table Top Epoxy, and more.

Here's how to use them:

  1. Measure the length, width, and depth of your project in inches.

  2. Enter these measurements into the calculator fields.

  3. Select your epoxy formulation from the dropdown menu:

    • Each formulation has specific mixing ratios

    • Choose the one that matches your product

  4. Click Calculate to see your results.

  5. The calculator will show you the total volume needed and the exact amounts of resin and hardener to mix.

If you're on a mobile device, scroll down to use both of these handy calculators!

How do you calculate the mix ratio by weight?

Epoxy resin systems are mixed by weight rather than volume. This is because the density of the resin and hardener components can vary, and measuring by weight ensures the correct chemical ratio for proper curing.
Different epoxy formulations require different resin-to-hardener weight ratios. Using the wrong ratio can result in incomplete curing, sticky surfaces, or compromised strength and durability.
Each of our epoxy formulations has a specific resin-to-hardener ratio:

What are the actual formulas used?

The formulas used to calculate the epoxy volume needed, depends on the type of project you are working on.

For most applications (rectangular) you will follow these steps:

  • Measure the substrate (or piece) you will be using. Find the length and width in inches, and determine the depth that you would like to pour the epoxy (.25”, 1”, etc.)
  • Next multiply the 3 dimensions (L x W x H) together to calculate the volume of the top of your substrate in cubic inches.
  • Finally, convert the cubic inch volume to U.S. fluid ounces. To do this you will divide your cubic inches by 1.805. (Cubic Inches / 1.805 = Fluid Ounces)
  • Bonus Tip: To convert ounces to gallons, you can divide by 128! (Fluid Ounces / 128 = Gallons)

How do I calculate the weight ratio myself?

To calculate the liquid volume needed of each side for your mix, you will follow these steps:

  • First, determine the total amount of epoxy needed.
  • Next, take the total weight of epoxy needed and divide by the ratio percentage to calculate the weight of Base Resin need: (Total Weight / Ratio Percentage = A Side)
  • Finally, subtract your A side weight from the total weight needed for the project to calculate your amount of Curing Agent: (Total Weight – A Side = B Side).

Especially in smaller mix volumes, it is incredibly important to keep the ratios exact.

Calculating your mix by volume can help to avoid a lot of math and limit the room for error.

Remember that some epoxy may be lost in the calculating stage, so it is a good idea to account for more epoxy than you need for your project.

It is always better to have left over epoxy, rather than to not have enough for your project.
