Cylinder Resin Calculator
Cylinders need diameter and height, not length and width. This page targets tumbler inserts, round columns, candle-style molds, and other straight-sided round castings.

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
- Uses diameter and height for cylinder-shaped resin casts.
- Good for straight-sided round molds and inserts.
- Shows raw cylinder volume and buffered order quantity.
- Links to sphere and circle pages for nearby shapes.
How to measure or set the inputs
- Measure the inside diameter and fill height of the cylinder.
- Use final filled height, not outside mold height.
- Add waste for pour spouts, inclusions, and trimming.
- For hollow cylinders, subtract the inner cylinder volume or use a water test.
Common mistakes that cost money
- Entering radius when the form asks for diameter.
- Using outside mold size instead of inside cavity.
- Ignoring a hollow center or large embedded object.
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
Can this calculate a hollow cylinder?
Not directly. Calculate the outside cylinder and subtract the inside cylinder volume, or use a water-fill test for the mold.
Is height the same as depth?
For cylinder molds, height is the filled vertical dimension of the resin cast.
Can I use this for a round tabletop?
Use the circle or round table page for shallow round tabletops. This page is for cylinder-style casts.
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.
