Tufted puffins are around {{convert|35|cm|in|abbr=on}} in length with a similar wingspan and weigh about three-quarters of a kilogram (1.6&nbsp; lbs), making them the largest of all the puffins. Birds from the western Pacific population are somewhat larger than those from the eastern Pacific, and male birds tend to be slightly larger than females.<ref name="Gaston">{{ cite book|author1=Gaston, A.

They are primarily black with a white facial patch, and, typical of other puffin species, feature a very thick bill, primarily red with some yellow and occasionally green markings. Their most distinctive feature and namesake are the yellow tufts ({{langx|la|cirri}}) that appear annually on birds of both sexes as the summer reproductive season approaches. Their feet become bright red and their face is also bright white in the summer. During the feeding season, the tufts molt off and the plumage, beak, and legs lose much of their luster.

As among other alcids, the wings are relatively short, adapted for diving, underwater swimming, and capturing prey rather than gliding, of which they are incapable. As a consequence, they have thick, dark [[myoglobin]]-rich breast muscles adapted for a fast and [[Aerobic exercise|aerobically]] strenuous wing-beat cadence, which they can nonetheless maintain for long periods of time.

Juvenile tufted puffins resemble winter adults, but with a grey-brown breast shading to white on the belly, and a shallow, yellowish-brown bill.<ref name="Gaston"/> Overall, they resemble a horn-less and unmarked [[rhinoceros auklet]] (''Cerorhinca monocerata'').
