The common warthog is a medium-sized species, with a head-and-body length ranging from 0.9 to 1.5 metres (2 feet 11 inches to 4 feet 11 inches), and shoulder height from 63.5 to 85 cm (2 ft 1 in to 2 ft 9+1⁄2 in). Females, at 45 to 75 kilograms (99 to 165 pounds), are typically slightly smaller and lighter in weight than males, at 60 to 150 kg (130 to 330 lb).[4][5] A warthog is identifiable by the two pairs of tusks protruding from the mouth and curving upwards.
