Resin Calculator: How Much Resin Do You Need?

Last updated

You're ready to start on your next resin project. You have the vision, the tools, and a general idea of the process. There's one question in your head; "How much resin do I need?" 

At Carved, all our wooden phone cases are made to the exact specifications of the Apple iPhone & Samsung Galaxy phones. Because of this, we use nearly the same amount of resin and hardener for almost every phone case. But when we make new monoliths, wallets, and pocket knives, we ask ourselves the same question: "How much resin do we need to make this?"

We built this resin calculator to make it easy on ourselves (and you).

Calculate Based on Dimensions (in inches)

Just enter your project's length, width, and height in inches, and our calculator will tell you how many fluid ounces of resin you need to bring your vision to life. 

For the math nerds, this is the equation we use to calculate how much resin we'll need for a project: 

((Length * Width * Height) / 1.805)

Length, width, and height are all in inches, and output is in fluid ounces.

NOTE: To convert fluid ounces to gallons (for larger resin projects), divide the output by 128. 

Calculate Based on Ratio (by volume)

Resin has two parts, the resin and the hardener. These are also called parts A and B. Various resins have different ratios when mixing those two parts, some by weight and some by volume. Once you've calculated the volume of resin required (in fluid ounces), click "Calculate Side A and Side B" on the second calculator to find your ratio by volume in fluid ounces.

Why Resin Measurements Are Important

The first step to creating beautiful resin art is figuring out how much resin you'll require for your project. Overestimating the amount leads to resource waste, costing you more money than it should. Refraining from overestimating the resin quantity for art or any project can interrupt the creative flow and might lead to imperfect outcomes. An accurate volume calculation for resin ensures the correct thickness of the artwork or furniture, improving the aesthetic appeal and durability. 

Frequently Asked Questions

How much does a gallon of resin cover?

Typically, tabletop and bartop epoxies provide approximately 12 sq feet of coverage per mixed gallon at a thickness of 1/8".

What happens if you pour too much resin?

Pouring too much resin can cause the epoxy to crack due to overheating during curing. It's, therefore, essential to maintain the correct depth, often not exceeding 1/2" for tabletop epoxy.
