Shrimp range in size from colossal to extra-small, but how can we be sure what exactly we’re getting?
Shrimp size names are not standardized. Because these names vary from vendor to vendor and store to store, one company’s large is another company’s extra large. The best way to eliminate ambiguity is to disregard the name and select shrimp based on the actual count per pound, which is clearly labeled on the packaging.
According to the American Shrimp Processors Association, “The shrimp count on a bag of wild-caught U.S. shrimp is the number that denotes how many shrimp are approximately in the bag ‛per pound.’”
The letter U (for “under”) means that there should be fewer than that number of shrimp in a pound; two numbers separated by a slash indicates the range of shrimp per pound in that particular size.
The smaller the number per pound, the bigger the shrimp.
U/12: no more than 12 shrimp per pound
16/20: between 16 and 20 per pound
21/25: between 21 and 25 per pound
26/30: between 26 and 30 per pound
41/45: between 41 and 45 per pound
51/60: between 51 and 60 per pound
