The adult Great Plains toad averages 4.8-9 cm in length. On its back it has large dark blotches. Each blotch is boldly bordered by light pigment and contains many warts. The colors of this toad are generally yellowish, brown, greenish, or gray on top. Below is unspotted, cream to white, with a yellow or orange-yellow seat patch. Some specimens have been found with a narrow, light mid dorsal stripe. The head of the Great Plains toad is relatively small with a well-developed cranial crest. Their snout is blunt and rounded.
The Great Plains Toad call is a high pitched, long mechanical trill resembling the burst of a machine gun. A breeding chorus can be heard for up to two kilometers across the prairies.
