The ashy-throated chlorospingus is 13 to 14 cm (5.1 to 5.5 in) long and weighs 14.5 to 21 g (0.51 to 0.74 oz). The sexes have the same plumage. Adults of the nominate subspecies C. c. canigularis have a mostly gray head with slightly darker ear coverts and a grayish white throat.

The centers of their breast and belly are whitish to grayish white and their undertail coverts olive-yellow. Voice: In Peru, subspecies C. c. signatus of the ashy-throated chlorospingus sings "an accelerating series of high chipping notes that falls, then rises in pitch". There its call is "a dry, metallic tik, usually given in a stuttered series". In Colombia the species sings "tsuk...tsuk...chit-chit chi’t’t’t’t’t’t’a’a’a’a’i’i’it’it-tit, trill rising slightly, then descending, and rising again at end".
