Estimate resin for silicone molds, casting molds, trays, blocks, and simple mold cavities with waste and cost guidance.
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.

Use the estimate to narrow the resin class first. Then confirm product limits, cure behavior, and measurement assumptions before you make a buying decision.
Measurement diagram
How much resin does a cylinder mold need?
Cylinder volume is π × radius² × height. A mold 3 in wide and 6 in tall holds about 695 ml (23.5 fl oz), and a 4 × 8 in mold about 1,647 ml (55.7 fl oz) before waste. Measure the inside diameter and the height you will actually fill; the table adds the calculator's default 10%.
| Inside diameter × fill height | Raw resin | With 10% waste |
|---|---|---|
| 2 × 4 in (5.1 × 10.2 cm) | 206 ml (7 fl oz) | 227 ml (7.7 fl oz) |
| 3 × 4 in (7.6 × 10.2 cm) | 463 ml (15.7 fl oz) | 510 ml (17.2 fl oz) |
| 3 × 6 in (7.6 × 15.2 cm) | 695 ml (23.5 fl oz) | 764 ml (25.9 fl oz) |
| 4 × 6 in (10.2 × 15.2 cm) | 1,236 ml (41.8 fl oz) | 1,359 ml (46 fl oz) |
| 4 × 8 in (10.2 × 20.3 cm) | 1,647 ml (55.7 fl oz) | 1,812 ml (61.3 fl oz) |
Measure the inside diameter and filled height
A solid cylinder 3 cm in inside diameter and 5 cm high contains π × 1.5² × 5 = 35.343 mL. Four such pieces with 10% waste need 155.51 mL. This model is solid: a tumbler wall or hollow insert needs its inside void subtracted, or a known mixed capacity. It does not estimate an outside coating from a full solid cylinder.
Product data before mixing
Use the exact product documentation for mixing basis, maximum layer depth, mixed batch volume and cure or recoat conditions. A dimensional estimate and a purchase allowance do not supply those material limits.
What this calculator covers
- 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
- Choose inside geometry for a regular shape, or use a known cavity capacity where that mode is available.
- Set the number of identical pieces; the main quantity is the total batch, with a separate loss allowance.
- Check the raw quantity against a hand calculation or a product's published mixed capacity.
- Enter product ratio, limits and total kit mixed yield only when confirmed; purchase quantity is not a batch-mixing instruction.
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.
