Gummy Mold Size Chart: Weight, Volume & Cavity Planning
Example cavity volumes from target grams: 1 g, 2 g, 3 g, 5 g, 10 g at a 1.20 g/mL planning density. Confirm with your pectin or gelatin.

Choosing a gummy mold size starts with the finished gummy requirement: target piece weight, dimensions, formula, shape, logo/detail and production method.
The tables on this page are planning examples, not industry standards. Gummy density and final weight vary by formulation and process, so the final cavity should be validated with the actual formula and a prototype before production.

Start With Target Weight and One Known Dimension
A practical early-stage brief includes:
- target grams per gummy
- formula type: pectin, gelatin or other
- shape
- one or more known dimensions
- logo/detail
- target cavity count
- tray-size limit
- depositor pitch/nozzle count if applicable
The goal of the first cavity is to create a testable geometry, not to claim a universal “standard gummy size.”
Weight and Cavity Volume Are Related, but Formula Density Matters
Use:
Weight = Volume × Density
or
Volume = Target Weight ÷ Density
The density value must come from the actual formulation or a documented process assumption.
If the formula density is not known, use a planning assumption only to create the first prototype and then correct the cavity using actual filled weight.
Example
If the target gummy is 3.0 g and the actual formula density is measured at 1.20 g/mL:
Required volume ≈ 3.0 ÷ 1.20 = 2.50 mL
This is a design starting point. The final cavity may still need adjustment for process, meniscus, fill level and finished product geometry.
Example Gummy Size Ranges — Not Industry Standards
The examples below are only for early planning. They do not define an industry standard and do not guarantee the finished gummy weight.
For the example volumes, assume a planning density of 1.20 g/mL only for illustration. Replace that assumption with the real formulation density before final cavity approval.
| Example Category | Target Weight | Illustrative Cavity Volume at 1.20 g/mL | Example Design Direction |
|---|---|---|---|
| Mini | 1.0 g | about 0.83 mL | compact icon, small bear, simple square |
| Small | 2.0 g | about 1.67 mL | small branded shape, bear, rounded block |
| Medium | 3.0 g | about 2.50 mL | ring, bar, larger logo shape |
| Medium-Large | 5.0 g | about 4.17 mL | larger branded shape or novelty piece |
| Large | 10.0 g | about 8.33 mL | large novelty or functional gummy shape |
These volumes come from target weight ÷ assumed density. They are not production specifications. Final geometry must still account for shape, fill level, draft, logo detail and the actual formula.
Two Gummies Can Have the Same Weight and Very Different Dimensions
A 3 g gummy can be:
- short and thick
- wide and shallow
- tall and narrow
- ring-shaped
- sculptural
The shape affects:
- surface area
- logo/detail
- release
- cavity spacing
- depositor access
- how the gummy looks at the target weight
Do not choose dimensions from weight alone.
Leave Enough Geometry for the Brand Mark
When a logo is required, review:
- stroke width
- depth
- corner radius
- spacing
- draft
- gummy thickness behind the logo
- release direction
A small gummy with an overly complex mark may need simplified artwork.
Cavity Count Comes After the Gummy Geometry
Once the cavity is approved, define:
- tray width/length
- cavity pitch
- number of cavities
- filling method
- depositor pitch
- filled weight
- support tray/frame
- demolding sequence
Do not maximize cavity count before the handling method is known.
Lock Nozzle Pitch Before Final Tray Layout
For machine-filled gummy production, send:
- number of nozzles
- center-to-center pitch
- indexing direction
- machine reference points
- maximum tray dimensions
A production tray should be designed around the filling equipment rather than forcing the machine to match a finished tray later.
Pectin and Gelatin Are Not One Universal Density
Do not use one density number for every pectin or gelatin formula.
For final design:
- use actual formulation density if available
- fill the prototype
- weigh the finished gummy
- revise cavity volume if needed
- approve before production
Send:
- target grams
- formula type
- shape or CAD/artwork
- finished dimensions if known
- logo/detail
- tray size
- desired cavity count
- depositor pitch if used
- quantity
- destination market if food-contact documentation is required
Is there a standard gummy mold size?
There are common market examples, but there is no single industry-standard cavity size that guarantees a specific gummy weight. Weight depends on formulation, volume and process.
Can I calculate gummy weight from cavity dimensions?
You can estimate it if the cavity volume and actual formula density are known. Validate the final result with the real formula.
How many cavities should be in one tray?
It depends on cavity size, tray limits, filling method, filled weight, support and demolding workflow.
Should I choose pectin or gelatin before finalizing the mold?
If possible, yes. The formula affects density and release behavior, so validate the actual production formula before final approval.
