Main Characteristics. Cheetahs are tall, slender cats that are built for speed. They have a body length between 1.1 and 1.5 m (3.5 - 5 ft), a tail length between 60 - 80 cms (23.5 - 32 inches) and they weigh between 21 and 72 Kgs (46 - 160 lbs). They have long, muscular legs with blunt, semi-retractable claws which enables them to have better traction while running.
