According to the National Fisheries Institute, over one billion pounds of shrimp are consumed in the United States every year, with much of it sold in packages labeled with confusing number ranges. So, is 20/30 shrimp big? The simple answer is that it depends, as the 20/30 refers to the count per pound, not a specific length.

Quick Summary

The size of shrimp is determined by its count per pound, not a standardized name. The numbers 20/30 indicate that there are 20 to 30 shrimp in a single pound. These are considered extra-large to jumbo in size and are highly versatile for many dishes.

Key Points

Count Per Pound: Shrimp size is indicated by the number of shrimp in a pound; a lower number means a larger shrimp.
Extra-Large to Jumbo: The 20/30 shrimp count places it in the extra-large to jumbo category, making it substantial for many dishes.
Versatile for Cooking: This size is ideal for grilling, pan-searing, or featuring as the main protein in a recipe.
Reliable Measurement: Unlike descriptive names, the count-per-pound system is the most accurate way to compare shrimp sizes across different suppliers.
Impacts Cooking and Presentation: The size of the shrimp affects both how it should be cooked and its visual impact in the finished dish.
Cooking Quickly: Due to their size, 20/30 shrimp cook quickly and require careful attention to avoid overcooking and a rubbery texture.

Deciphering Shrimp Sizing: The 'Count Per Pound' System

Shrimp size is commonly indicated by a number range like 20/30, which represents the approximate number of individual shrimp per pound. A lower number signifies larger shrimp, while a higher number means smaller shrimp. This count-per-pound system is considered more reliable than descriptive terms such as "jumbo" or "large," which can vary by supplier. The count can also differ depending on whether the shrimp is sold with or without the shell.

How to Choose the Right Shrimp Size

Selecting the appropriate shrimp size depends on your recipe and how you plan to use it. Smaller shrimp (e.g., 51/60) are better for dishes like popcorn shrimp, while larger counts like 20/30 or U/15 are preferred for shrimp cocktail or main courses.
