The cheetah has a yellowish tan or rufous to greyish white skin, that is covered with nearly 2,000 solid black spots. The underbelly is completely white. It has a slender body, deep chest, a small rounded head, black tear-like streaks on the face, long thin legs and a long spotted tail. The head-and-body length ranges from 112–150 cm (44–59 in). Adult cheetahs average 70–90 cm (28–35 in) at the shoulder, and weigh 21–72 kg (46–159 lb).  Its lightly built, slender form is in sharp contrast with the robust build of the big cats.  It is taller than the leopard, which stands nearly 55–70 cm (22–28 in) at the shoulder. The weight range of the cheetah overlaps with that of the leopard, which weighs 28–65 kg (62–143 lb). On the other hand, the cheetah is significantly shorter than the lion, whose average height is nearly 120 cm (47 in). Moreover, it is much lighter than the lion, among which females weigh 126 kg (278 lb) and the much heavier males weigh 186 kg (410 lb).  Based on measurements, the smallest cheetahs have been reported from the Sahara, northeastern Africa and Iran. A sexually dimorphic species, males are generally larger than females.
