Sizing Up Your King Crab Legs

Sizing Up Your King Crab Legs

When customers are shopping for King Crab Legs and see sizes listed like 4/7, 6/9, 9/12 and others, they often wonder what those numbers represent. In addition to those numbers, consumers will hear terms like Jumbo, Colossal, Super Colossal and others used to describe the different sizes of King Crab, which often only adds to their confusion. As a result, one of the most commonly asked questions we receive at Custom Seafoods regarding our King Crab is, “What do all the different numbers and terms mean”? The most important thing to remember is that King Crab sizes are NOT based on one-pound measurements. Instead, King Crab Legs are marketed and sized according to the number of crab legs it would take to make a ten-pound box. For example, crab legs sized as 6/9 indicate that it would take 6 to 9 of that size crab legs to make a ten-pound package. Similarly, crab legs sized as 14/17 indicate that it would take 14 to 17 of those size legs to fill a ten-pound box. As a general rule, the smaller the number, the larger the individual crab leg would be. To help with understanding what all of this means, we have put together this handy infographic to explain the differences:
