The Swedish Blue is a medium-sized bird: the male weighs between and the female usually weighs . Swedish ducks are regularly compared to the body type of Cayugas and Orpingtons, however Swedish should have shorter bodies with more width compared to what is seen in those two breeds. Blue Swedish have medium, oval-shaped heads. Color should be a consistent blue-slate with darker lacing around the border of each feather. Drakes are generally darker than ducks. The only part of the birds that is not some variety of blue is the white, heart-shaped bib found on the breast, extending up the front of the neck terminating towards the mandible of the bird. It is distinguished from the Pomeranian Duck by its white primaries.
