Estimate resin for dice molds and cube-shaped resin casts by side length, waste buffer, and project cost.
Cube Resin Calculator
A cube is simple, but a dedicated page removes confusion for dice blanks, block molds, and square casting forms. Enter the side length and let the calculator handle volume and buying buffer.

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.

How much resin does a cube mold need?
A cube holds side³, so doubling the side multiplies the resin by eight: a 2 in cube needs about 131 ml (4.4 fl oz) and a 4 in cube about 1,049 ml (35.5 fl oz) before waste. The table adds the calculator's default 12% for overflow and trimming.
| Inside side length | Raw resin | With 12% waste |
|---|---|---|
| 1 in (2.5 cm) | 16.4 ml (0.55 fl oz) | 18.4 ml (0.62 fl oz) |
| 2 in (5.1 cm) | 131 ml (4.4 fl oz) | 147 ml (5 fl oz) |
| 3 in (7.6 cm) | 442 ml (15 fl oz) | 496 ml (16.8 fl oz) |
| 4 in (10.2 cm) | 1,049 ml (35.5 fl oz) | 1,175 ml (39.7 fl oz) |
| 6 in (15.2 cm) | 3,540 ml (119.7 fl oz) | 3,964 ml (134.1 fl oz) |
Use one consistent side length
A 4 cm cube contains 64 cm³ = 64 mL. Two identical cubes with 12% waste require 143.36 mL. A rounded or beveled mold contains less than a sharp-cornered cube with the same outside size. Cube geometry is a planning approximation; known cavity capacity is preferable when available. The quantity field counts identical filled pieces, not unrelated dice shapes.
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 one side length for true cube molds.
- Works for block castings, dice blanks, and square resin forms.
- Shows raw cube volume, waste-adjusted quantity, and cost.
- Links to dice and rectangular pages when shape assumptions differ.
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
- Using a cube calculator when the mold is actually rectangular.
- Entering outside mold dimensions instead of the inside cavity.
- Ignoring sprues or overflow channels.
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
What if my mold is not a perfect cube?
Use the rectangle calculator when length, width, and depth are not all the same.
Can this page estimate dice blanks?
Yes for cube-style blanks. Use the dice page if you want dice-specific batching guidance.
Should I add extra for sanding?
Yes if you intentionally overfill or expect trimming and sanding loss.
