About Resin Calculator

Resin Calculator is a free online tool built for epoxy resin crafters, artists, and professionals. Whether you make coasters, river tables, jewelry, or art canvases, getting the resin-to-hardener ratio right is the difference between a perfect pour and a sticky mess.

Why We Built This

We got tired of guessing. Most resin packaging gives you a ratio but no easy way to figure out how many milliliters of each component you actually need for your specific mold. So we built a calculator that does exactly that — enter your dimensions, pick a shape, choose your ratio, and get precise measurements in ml, grams, or liters.

How the Resin Calculator Works

The tool calculates the volume of your mold using standard geometry formulas (length × width × depth for rectangles, π × r² × depth for circles). Then it splits the total volume according to your mixing ratio. The result is the exact amount of Part A (resin) and Part B (hardener) you need to pour.

Who It's For

• Beginners learning how to measure resin for the first time
• Experienced crafters who want precision without mental math
• Professionals calculating material costs for large projects
• Teachers and workshop leaders who need quick references
