The buff-tailed coronet has only slight sexual dimorphism. The female is scaled with white feathers mostly throughout the chin and throat, and some on the belly. Prominent feather colorations are iridescent green with darker wing tips, and buffy hues under the wing and tail feathers. On the face, there is an obvious white post ocular spot on each side. Puffy white “boots” are present at the thighs, an orange tuft at the shoulder, and a short, dark bill. Average size for a buff-tailed coronet is 13.2-13.5 cm with a bill length of 1.8–2 cm.

The buff-tailed coronet and fawn-breasted brilliant are commonly confused due to their similar posterior coloration. The fawn-breasted brilliant has more buff coloration on its breast and underbelly.
