Head and throat of Marsh Tit are black with bluish metallic gloss (in fresh plumage throat is with pale edges of feathers); other upperparts are pale-grey brownish tinged. Flight feathers are dark-brownish with washed pale edges, tail feathers are dark-brownish. Cheeks and underparts are off-white with brownish tone on flanks and rear-belly. Bill is black, eyes are brownish, legs are grayish. Juveniles in first plumage have not black but dark-brownish head and throat.

Males and females are similar. Sizes: wing 60-69, tail 54-69, tarsus 15-17, bill 6.9-9.0 mm. Weight 10-12.5 gr.
