21/25 means there are approximately 21 to 25 shrimp per pound. The lower the count, the larger each shrimp is. For example, 16/20 shrimp are larger than 21/25 shrimp, while 31/40 shrimp are smaller.
Shrimp size is only one part of the label. Terms such as HOSO, HLSO, PDTO, and PD describe the shrimp product form rather than the size.

The actual size of shrimp can vary slightly by species and origin, but this gives you a good idea.
What is 21/25 Shrimp Best For?
21/25 shrimp are a versatile size that works especially well when you want the shrimp to stand out in the dish. They are a good choice for gambas (Spanish-style garlic shrimp), grilled shrimp, garlic butter shrimp, and shrimp-focused pasta dishes. For pasta, the best size depends on whether the shrimp or the pasta is meant to be the star of the dish. For dishes like fried rice, where shrimp is usually one of many ingredients, a smaller size may be a more practical choice.
Does Shrimp Size Affect Price?
In general, larger shrimp tend to be more expensive. However, size is not the only factor that affects shrimp prices. Origin, species, product form, processing, and supply and demand can also influence the price.
How to Choose the Right Shrimp Size
There is no single “best” shrimp size for every recipe. As a simple rule, choose larger shrimp when shrimp is the star of the dish and smaller shrimp when it is mixed with several other ingredients.
