How to Read Shrimp Sizes

So how do you read shrimp sizing? In the seafood industry, shrimp are labeled by the number of pieces in a pound. You can find this number on 1) the bag of frozen shrimp or 2) labels at the seafood counter.

This bag of frozen shrimp is labeled “16-20,” which means 16 to 20 shrimp in one pound.

Note: some brands may call 16/20 “Jumbo,” while others refer to the same count as “Extra Jumbo.” For this reason, we recommend buying shrimp based on counts vs. their general size names.

16 20 Count Label on Package of Shrimp

A label with “51/60 count” means there are 51 to 60 pieces of shrimp per pound, which is often called “Small” shrimp. Whereas “U/10 count” refers to 10 or fewer pieces in a pound or “Extra Colossal” shrimp. The smaller the number, the larger the shrimp.


The smaller the number, the larger the shrimp.

E.G., Extra Colossal 10 and under, Tiny shrimp 71+

Common Shrimp Sizes and Counts per Pound

Here is a breakdown of common shrimp sizes and what they mean:

Extra colossal – 10 or under pieces of shrimp in a pound. (U/10 count)

Super colossal – 12 or fewer pieces of shrimp in a pound. (U/12 count)

Colossal – 15 or under pieces of shrimp in a pound. (U/15 count)

Extra jumbo – 16 to 20 pieces of shrimp in a pound. (16/20 count)

Jumbo – 21 to 25 pieces of shrimp in a pound. (21/25 count)

Extra large – 26 to 30 pieces of shrimp in a pound. (26/30 count)

Large – 31 to 40 pieces of shrimp in a pound. (31/40 count)

Medium-large – 36 to 40 pieces of shrimp in a pound. (36/40 count)

Medium – 41 to 50 pieces of shrimp in a pound. (41/50 count)

Extra small – 61 to 70 pieces of shrimp in a pound. (61/70 count)

Tiny or salad style – 71+ pieces of shrimp in a pound. (71+ count)

Note: while these numbers will give you an estimated size range and count per pound for each type of shrimp, there will always be some variation.

In non-coastal or rural areas, it might be harder to find the “Colossal” and larger shrimp without special ordering or visiting a specialty seafood market. For example, here in Montana, we can usually find sizes ranging from “Extra Small” to “Extra Jumbo” at our local grocery stores. (Frozen or thawed-from-frozen in the fresh seafood case.)

What is the average size of a shrimp?

What is the serving size of shrimp?

Let’s look at shrimp serving sizes in terms of both ounces and shrimp counts.


According to the FDA, the serving size for seafood, including shrimp, is 3 ounces, cooked. However, shrimp count is the number of pieces in a pound of raw, uncooked shrimp. Because shrimp can lose up to 25% of their weight after cooking, a serving size is 3 ounces cooked, and approximately 4 ounces raw.


4 ounces raw × (1 – .25) = 3 ounces cooked

*shrimp can lose about 25% of their weight after cooking


The number of shrimp per serving depends on the size of the shrimp. A serving of tiny salad shrimp (71+ per pound) is close to 17+ shrimp, while a serving of Colossal (U/15) shrimp is 3 to 4 shrimp. See the serving size column in the chart above for the approximate serving size for each shrimp size (in terms of cooked shrimp).


Count per lb ÷ 16 oz = count per ounce

Count per ounce × 4 oz = # of shrimp per serving

*71+ count/lb ÷ 16 oz x 4 oz/serving = 17+ tiny shrimp per serving

How much shrimp per person?

If shrimp is the main entrée, plan to use at least 4 ounces per person, raw (approximately 3 ounces cooked). Some people plan for 6 to 8 ounces per person to have plenty and be on the safe side. If your meal is similar to a shrimp boil where many other ingredients will be added, you can use safely use 4 ounces per person.

Baking – for baked shrimp, stick to larger sizes like Extra Large to Colossal. Smaller sizes are easy to overcook in the oven.

Barbecue/Grilling – plan to use Large to Colossal sizes, and skewer when possible.

Deep Frying – all sizes can be easily fried, but consider butterflying anything Jumbo or larger to help them cook properly.

Pan Frying/Sautéing, Steaming, Boiling, and Broiling – will work great for all sizes, just be careful not to overcook the smaller sizes.
