Volume Estimator
The Volume Estimator helps you predict the total volume of your finished ice cream — including the air incorporated during churning and any inclusions folded in afterward. This is essential when you need to know how many containers a batch will fill, or when planning production quantities for specific container sizes.
The tool calculates volume from three components: your base mix, the air from overrun, and the physical space taken up by inclusions like chocolate chips, fruit, or cookie pieces.
How to Access the Volume Estimator
You can open the Volume Estimator in two ways:
- Go to Tools in the navigation menu and click the Volume Estimator card.
- Navigate directly to /tools/volume-estimator in your browser.
Using a Recipe
You can either enter values manually or load them from one of your recipes. Click the Select Recipe button at the top of the page to choose a recipe. When a recipe is loaded, the following values are automatically filled in:
- Mix weight — set to the recipe’s final weight (after evaporation)
- Mix density — calculated from the recipe’s composition
- Overrun — taken from the recipe’s overrun setting, if one is set
- Inclusions — any ingredients marked as inclusions in the recipe are added automatically with their displacement values
You can switch to a different recipe with the Change Recipe button, or click Clear to remove the recipe and enter values manually.
Base Mix
The Base Mix card on the left side contains three inputs that define your ice cream base before inclusions are added.
Mix weight (g) is the total weight of your mix in grams. If you loaded a recipe, this comes from the recipe’s final weight. The default is 1000g.
Mix density (g/mL) controls how much space the mix occupies per gram. A typical ice cream mix has a density around 1.10 g/mL. Higher-fat mixes tend to be slightly less dense. If you loaded a recipe, this is calculated automatically from the recipe composition.
Expected overrun (%) is how much air is incorporated during churning, expressed as a percentage of the original mix volume. Typical ranges are:
- 20–40% for gelato
- 50–100% for ice cream
- 100%+ for very light, commercial-style ice cream
Below the inputs, the card shows two calculated values: the mix volume (weight divided by density) and the aerated volume (mix volume plus the air from overrun).
Inclusions
The Inclusions card lets you add the mix-ins that get folded into the ice cream after churning. Each inclusion takes up physical space, and the Volume Estimator accounts for this using displacement — the actual volume that 100 grams of an inclusion occupies inside the ice cream.
Displacement is not the same as measuring-cup volume. A cup of chocolate chips has air gaps between the chips, but when folded into ice cream, only the chocolate itself displaces volume. Dense items like fudge displace less space per gram, while airy items like meringue pieces displace much more.
Adding Inclusions from the Library
The built-in library contains over 80 common inclusions across seven categories: Chocolate, Candy, Nuts, Fruit, Dried Fruit, Cookie & Cake, and Cereal & Crunchy, plus Sauces & Ripples. Each comes with a pre-set displacement value based on the ingredient’s density and form.
- Type in the Search and add inclusion field. Results appear as you type, showing the name, category, and displacement value.
- Click an item to add it. It appears in the list below with a default weight of 100g.
- Adjust the Weight (g) to match your recipe.
- If needed, adjust the Displacement (mL per 100g) value. The library defaults are reasonable estimates, but your specific product may differ.
Adding Custom Inclusions
For inclusions not in the library, click Add custom inclusion. Custom inclusions have a bulkiness slider that maps to displacement values across seven levels:
| Level | Label | Displacement | Examples |
|---|---|---|---|
| 1 | Very Dense | 75 mL/100g | Fudge sauce, dulce de leche, honey |
| 2 | Dense | 85 mL/100g | Chocolate chips, raisins, gummy bears |
| 3 | Medium-Dense | 100 mL/100g | Fruit pieces, cookie dough, M&M’s |
| 4 | Medium | 115 mL/100g | Brownie pieces, chopped nuts, biscuit crumbs |
| 5 | Medium-Light | 140 mL/100g | Cake pieces, cookie chunks, sliced almonds |
| 6 | Light | 180 mL/100g | Chocolate shavings, coconut flakes, waffle pieces |
| 7 | Very Light | 220 mL/100g | Maltesers, meringue, honeycomb, puffed rice |
Think about how heavy the ingredient feels for its size. A handful of chocolate chips feels heavy (Dense). A handful of meringue pieces feels very light (Very Light). If you need more precision, click the fine-tune link below the slider to enter an exact displacement value.
Measuring Displacement Precisely
For the most accurate displacement value, you can measure it directly: submerge 100g of the inclusion in water and measure the water level rise in mL. That rise is your exact displacement value in mL per 100g.
Results
The Results card at the bottom combines everything into a final volume estimate. It shows:
- The total volume in both mL and liters, displayed prominently at the top
- The total weight in grams and kilograms
- A visual breakdown bar showing the proportion of base mix (dark blue), air from overrun (light blue), and inclusions (orange)
- A legend with exact volumes and percentages for each component
Below the breakdown, you will find per-liter statistics:
- Weight per liter — useful for labeling and container planning
- Inclusion % of volume — how much of the total space is taken up by inclusions
- Inclusion % of weight — the weight proportion of inclusions in the total
- Average density (with air) — the overall density of the finished product including air
Tips
- If you are unsure about overrun, start with 30% for gelato or 60% for ice cream as a reasonable starting point, then adjust based on your machine and process.
- Displacement values in the library are estimates. If accuracy matters for your production, measure displacement using the water submersion method described above.
- The form of an inclusion affects its displacement. For example, whole Maltesers (210 mL/100g) displace far more than crushed Maltesers (130 mL/100g) because crushing collapses the air inside.
- Sauce and ripple inclusions have the lowest displacement values (72–80 mL/100g) because they are dense liquids with no air.
- All values update in real time as you type — there is no need to click a “calculate” button.
