Resin Calculator- How much resin do you need?

Updated: Mar 5, 2021

Use the Mermaid Trash epoxy resin calculator to mix the right amount of resin for your next project.

Enter your project measurements below in inches.

When it comes to coating a rectangular surface, the basic formula for epoxy resin coverage is quite simple:

First, measure the piece. You’ll need to know length and width in inches. You’ll also need to know how thick you’d like the epoxy finish to be. Multiply these 3 measurements together to calculate the volume for the top of the table (or bar, or countertop) in cubic inches. To convert cubic inch volume to US fluid ounces, divide by 1.805. To convert ounces to gallons, divide by 128.

Working with a round table? Easy. For a round surface, you will need to measure the diameter. Divide the diameter by 2 to calculate the radius. To calculate volume in cubic inches: (radius squared) X pi (or, 3.14159265) x (desired epoxy coating thickness). Divide by 1.805 to convert cubic inch volume to US fluid ounces. To convert ounces to gallons, divide by 128.
