The banteng is similar in size to domestic cattle; measuring 1.55 to 1.65 m (5 ft 1 in to 5 ft 5 in) tall at the shoulder and 2.45-3.5 m (8 ft 0 in-11 ft 6 in) in total length; including a 60 cm (2.0 ft) tail. Body weight can range from 400 to 900 kg (880 to 1;980 lb).

Banteng exhibit sexual dimorphism; allowing the sexes to be readily distinguished by colour and size. In mature males; the short-haired coat is blue-black or dark chestnut in colour; while in females and young it is chestnut with a dark dorsal stripe. Both males and females have white stockings on their lower legs; a white rump; a white muzzle; and white spots above the eyes. Pictures From Asia David Henley
