The moustached warbler is 12–13 cm (4.7–5.1 in) long, slightly smaller than the similar sedge warbler (Acrocephalus schoenobaenus). The adult has a finely streaked brown back and white underparts. The forehead is flattened, there is a prominent whitish supercilium, grey ear coverts, and the bill is strong and pointed. The sexes are identical, as with most warblers, but young birds are more heavily streaked and have markings on the breast.
