The size of a shrimp is indicated by the count or number of shrimp per pound. The smaller the number, the larger the shrimp. Shrimp size terminology varies from place to place, so the count is the most accurate way to call for shrimp in a recipe. A basic guideline is: 11 to 15 is jumbo; 16 to 20 is extra large; 21 to 30 is large; 31 to 35 is medium and 36 to 45 is small.
