Males measure 39–40 mm (1.5–1.6 in) and females 55–64 mm (2.2–2.5 in) in snout–vent length.
The head is comparatively flat.
Males have white throats.
Parotoid glands are moderately developed.

The adult frogs live in patches of shrubby vegetation occurring on the inselbergs or gneiss domes in the forest on which it lives.
Tadpoles are unusual compared to other Sclerophrys species: they are not aquatic but semi-terrestrial, living in shallow water-films on wet, sometimes nearly vertical rocks.
