It is a small, short-winged, warbler like bird with relatively long legs. It is 12 cm in length and weighs 7-14.5 g, with a wing length of 54.5 mm. Sexes look similar to each other. It has grayish brown upperparts and is pale warm buff in colour under. The nominate species has a cold grayish brown head and upperparts, with the sides of head and neck being a lighter grayish-brown. Its tail is also grayish brown, with off-white undertail coverts.
