How disher numbers work
A disher is a portion scoop with a number stamped on it. The Institute of Child Nutrition explains the system on its USDA-funded “Basics at a Glance” poster: the number on the scoop is how many level scoopfuls make one quart.
That makes the math simple. There are 32 fluid ounces in a quart, so a scoop’s size in fluid ounces is about 32 divided by its number. For example, 8 level #8 scoops fill a quart, and each holds 4 fluid ounces.
The printed level measures do not always match that division exactly. A #10 is listed as 3/8 cup, which is 3 fluid ounces, while 32 divided by 10 would be 3.2. The chart uses the printed level measures.
The bigger the number, the smaller the scoop. A #6 is large. A #40 is a small bite.
Reading the chart: ounces, milliliters and grams
For each disher number, the chart gives:
- The level measure in cups or tablespoons
- Fluid ounces
- Milliliters
- Grams
- Scoops per pint, quart, half gallon and gallon
A few common sizes, in prose:
- A #6 is 2/3 cup level, about 5.33 fluid ounces or 158 milliliters.
- A #8 is 1/2 cup level, 4 fluid ounces or 118 milliliters.
- A #12 is 1/3 cup level, about 2.67 fluid ounces or 79 milliliters.
- A #16 is 1/4 cup level, 2 fluid ounces or 59 milliliters.
- A #30 is 2 tablespoons level, 1 fluid ounce or 30 milliliters.
All of these assume a level scoop. A rounded or heaped scoop holds more than the chart shows.
Why the grams are an estimate
Ice cream is part air. Makers call the added air “overrun,” and it changes how much a scoop weighs. The chart’s gram column uses 0.55 grams per milliliter. That figure comes from the University of Guelph’s Ice Cream Technology e-Book and describes a standard ice cream at 100% overrun, made from a mix that weighs 1.1 kilograms per liter.
Denser ice cream weighs more per scoop. At 50% overrun it comes to about 0.73 grams per milliliter, so a #8 scoop would weigh about 87 grams instead of the chart’s 65 grams. If you are weighing portions of a dense, premium-style ice cream, expect heavier scoops than the chart lists.
How many scoops in a gallon
To find scoops per container, divide the container’s fluid ounces by the scoop’s fluid ounces. Use these container sizes:
- Pint: 16 fluid ounces
- Quart: 32 fluid ounces
- Half gallon: 64 fluid ounces
- Gallon: 128 fluid ounces
So a gallon gives 32 level #8 scoops, 48 level #12 scoops, or 64 level #16 scoops. Some numbers do not divide evenly. A #10 gives about 42.7 scoops per gallon, and a #20 gives about 76.8. Round down when you plan.
Here is a planning example. You are serving 60 guests one #8 scoop each. A gallon gives 32 #8 scoops, so 2 gallons give 64. That covers everyone with a small cushion. If you would rather not do the math, the Scoop Planner is linked right after the chart. Like our other calculators, it runs in your browser, and the numbers you type are not sent to our server.
Scoops per 3-gallon tub
Scoop shops dip from 3-gallon cans, which hold 384 fluid ounces. Level scoops per can:
- #6: 72
- #8: 96
- #10: 128
- #12: 144
- #16: 192
- #20: 230
- #24: 288
- #30: 384
- #40: 460
Ice cream serving size: what counts as one
Since the 2016 Nutrition Facts label update, the U.S. Food and Drug Administration sets the reference amount for a serving of ice cream at 2/3 cup. Before that, it was 1/2 cup.
In scoop terms:
- A level #6 (2/3 cup) is one current label serving.
- A level #8 (1/2 cup) matches the old serving size.
You do not have to serve a label serving. A smaller scoop, like a #12 or #16, works well next to cake or pie. The label serving is simply a useful reference when you are matching portions to a carton’s nutrition panel.
Picking a scoop for your kitchen
For hosts. A #8 or #10 makes a generous single scoop in a bowl or cone. If you are serving dessert alongside something else, a #12 or #16 keeps portions sensible and stretches each gallon further.
For school and church kitchen volunteers. Consistency matters most when you are feeding a line of people. The same Institute of Child Nutrition poster notes that level scoops, ladles and portion servers give more accurate portion control than serving spoons, which are not a standard volume. Pick one disher number, level each scoop, and your count per gallon will hold up.
For small shop owners. Shops keep 3-gallon cans in a dipping cabinet. Cabinet makers such as Master-Bilt rate their cabinets by how many 9 1/2 inch, 3-gallon cans they hold. When you settle on one disher number for your standard scoop, you know how many scoops each can should give, using the 3-gallon figures above. That count is the starting point for pricing a scoop, which is what our Cost per Scoop tool helps with.
Read the number, not the color
Many dishers have colored handles, and it is tempting to remember sizes by color. Do not rely on it. Colors and handles differ between makers, and the poster marks its color column as brand-specific. A blue handle from one brand may be a different size from a blue handle from another. Always check the number stamped on the scoop.
FAQ
What size is a #8 scoop?
A #8 scoop holds 1/2 cup level, which is 4 fluid ounces or about 118 milliliters. Eight level #8 scoops fill a quart, and 32 fill a gallon.
How many scoops are in a quart?
It depends on the scoop. The disher number is the answer for a level scoop: 8 for a #8, 12 for a #12, 16 for a #16. For a #10, the printed measure gives about 10.7 per quart.
What scoop gives one FDA serving of ice cream?
A level #6 scoop holds 2/3 cup, the reference serving since the 2016 label update. A level #8 holds 1/2 cup, the serving size before that update.
Why does my scoop weigh more than the chart says?
The chart’s grams assume a standard ice cream at 100% overrun. Denser ice cream with less air weighs more per scoop, and a rounded scoop holds more than a level one.
Can I tell a scoop’s size by its handle color?
Not reliably. Colors differ between brands, so read the number stamped on the scoop instead.
