The [[carapace]] of ''C. pagurus'' adults is a reddish-brown colour, while in young specimens it is purple-brown. It occasionally bears white patches, and is shaped along the front edge into nine rounded lobes,<ref name="Macrobenthos"/> resembling a pie crust.<ref name="ARKive"/> Males typically have a carapace {{convert|60|mm|in|frac=4|abbr=on}} long, and females {{convert|98|mm|in|frac=4|abbr=on}} long, although they may reach up to {{convert|150|mm|in|frac=4|abbr=on}} long in exceptional cases.<ref name="Macrobenthos"/> Carapace width is typically {{convert|150|mm|in|frac=4|abbr=on}}, or exceptionally up to {{convert|250|mm|in|frac=4|abbr=on}}.<ref name="Marlin">{{cite web |url=http://www.marlin.ac.uk/speciesinformation.php?speciesID=2872 |title=Edible crab – ''Cancer pagurus'' |publisher=[[Marine Life Information Network]] |author1=Ken Neal |author2=Emily Wilson |year=2008}}</ref> A fold of the carapace extends ventrally to constitute a branchial chamber where the [[gill]]s lie.<ref name="Ingle">{{cite book |author=Ray W.

The first pereiopod is modified into a strong cheliped (claw-bearing leg); the claw's fingers, the [[arthropod leg|dactylus]] and propodus, are black at the tips.<ref name="Macrobenthos"/> The other pereiopods are covered with rows of short stiff [[seta]]e; the dactylus of each is black towards the tip, and ends in a sharp point.<ref name="Macrobenthos"/>

From the front, the [[antenna (biology)|antennae]] and [[antennule]]s are visible. Beside these,  the orbits are where the [[compound eye|eyes]] are situated.<ref name="Ingle"/> The [[Arthropod mouthparts|mouthparts]] comprise three pairs of [[maxilliped]]s, behind which are a pair of maxillae, a pair of maxillules, and finally the [[Mandible (arthropod mouthpart)|mandible]]s.<ref name="Ingle"/>
