Adult mountain zebras have a head-and-body length of 2.1 to 2.6 m (6 ft 11 in to 8 ft 6 in) and a tail of 40 to 55 cm (16 to 22 in) long. Shoulder height ranges from 1.16 to 1.5 m (3 ft 10 in to 4 ft 11 in). They weigh from 204 to 372 kg (450 to 820 lb). Groves and Bell found that the Cape mountain zebra exhibits sexual dimorphism, females being larger than males, whereas in Hartmann's mountain zebra they are not. Hartmann's zebra is on average slightly larger than the Cape mountain zebra.
