Perfect Ice Cream Calculator
Check how airy or dense your churned ice cream turned out by calculating its overrun, the standard measurement ice cream makers use for texture and yield.
What overrun measures
Overrun is the standard industry measurement of how much air gets whipped into ice cream during churning. Air is what gives ice cream its light, scoopable texture instead of being a solid block of frozen cream — but too much air makes it taste watery and thin, while too little makes it dense and icy.
The standard way to measure it is to weigh the same volume (like one cup) of your liquid mix before churning and your finished ice cream after churning and freezing. Because air weighs essentially nothing, the difference in weight for the same volume tells you how much air was incorporated. The formula is Overrun % = ((weight of mix – weight of ice cream) / weight of ice cream) × 100, using equal volumes of each.
- Premium, dense homemade ice cream typically has 20-50% overrun.
- Standard commercial ice cream often runs 50-100% overrun.
- Soft serve is usually on the higher end, around 30-60% or more, for its light texture.
This is a general kitchen-science reference for hobbyist ice cream makers; results depend on your churn method, mix recipe, and freezer performance.
