Separating crabs into various sizes is known as "grading". Over the years, individual markets have graded crabs differently, for marketing reasons. There is no industry standard for a "large" or "medium" crab. We have always tried to remain consistent and will tell you exactly what you are getting.

Live and steamed crabs average in size from 5" x 7", and are graded as follows, in our Annapolis Seafood Markets:

Females: 5" and up

Medium Males (#2's):
5" - 5 3/4"

Large Males (#1's):
5 3/4" - 6 1/2"

Jumbo Males:
6 1/2" and up
