The ash-winged antwren is 9.5 to 11 cm (3.7 to 4.3 in) long and weighs about 6.5 to 7.5 g (0.23 to 0.26 oz). The sexes have different plumage. Adult males of the nominate subspecies have a whitish supercilium and a thin dark line through the eye on an otherwise gray face. Their crown and nape are black, their back, rump, and uppertail coverts rufous-chestnut, and their tail gray-brown. Their wing coverts are black with white tips that form two bars on the closed wing and their flight feathers black with pale gray edges. Their entire underparts are pale gray that is lightest on the throat and belly. Adult females have a yellowish brown crown, nape, and upper back; their supercilium, throat, breast, and flanks have a buffy-brown tinge. Subadults of both sexes have olive-green edges on their flight feathers. Subspecies E. s. signata males have chestnut lesser wing coverts. Subspecies E. s. meridionalis has olive edges on its flight feathers and a greenish yellow tinge on the tips of the wing coverts and the belly.
