Epoxy Calculator
This epoxy resin calculator handles how much epoxy you need for common shapes and projects. Enter dimensions, and it converts raw geometry into an order-ready recommendation with waste, Part A / Part B split, and cost guidance.

Match the result to the right resin class
Use the estimate to narrow the resin class first. Then confirm product limits, cure behavior, and measurement assumptions before you make a buying decision.
Why this page exists
- Best for regular shapes, simple slabs, basic fills, and fast sanity checks.
- Shows raw volume, recommended order quantity, part A / Part B split, and budget.
- Helps you decide when to stay here and when to move to a more specific calculator.
- Covers rectangular and round inputs, including metric entries for people searching for a circle or resin volume calculator.
How to measure or set the inputs
- Pick the shape that most closely matches the cavity or pour area you are planning.
- Enter finished dimensions, not rough board size or mold outside dimensions.
- Use round mode for circular pours, round table estimates, and epoxy calculator circle searches.
- Switch the unit toggle before entering values if your notes are in metric.
- Increase the waste buffer if the project has porous edges, cup loss, runoff, or uncertain measurements.
Common mistakes that cost money
- Using the general page for river tables, garage floors, or other jobs with their own constraints.
- Treating raw geometric volume as the amount you should order.
- Choosing a resin before checking whether the job needs casting, deep-pour, or coating behavior.
Project checklist before you buy
- Confirm the mold or surface is sealed before mixing resin.
- Measure depth twice at the deepest point of the project.
- Add extra material for waste, seepage, and edge soak-in.
- Confirm the resin type matches the intended pour depth.
- Prepare cups, stir sticks, gloves, and a level work surface.
FAQ
Questions people ask before buying epoxy
When should I switch to a more specific calculator?
Use a scenario-specific page when the project introduces unique measurement or product constraints, such as river tables, garage floors, or countertop coatings.
Is this the right page for a first pass estimate?
Yes. This page is intended to be the fastest broad estimate for standard shapes. Once you know the project is irregular or product-limited, switch to the matching scenario page.
Why does this page show more resin than the raw math?
Because a buying decision is not the same as a pure geometry problem. Waste, mixing loss, and small measuring errors are normal, so the recommendation is intentionally more conservative than the raw volume.
How accurate is this epoxy calculator?
It is designed for planning and procurement, not for replacing the manufacturer data sheet. The calculator is most useful when you add the right waste buffer and choose the page that matches your project type.
Why does the recommended amount exceed the raw volume?
Real projects lose material to mixing cups, edge soak-in, seepage, and safety margin. Raw volume alone is often too optimistic.
Should I still check the resin brand instructions?
Yes. Always confirm maximum pour depth, cure conditions, and mix ratio with the product documentation you plan to buy.
