Tyrannosaurus rex was one of the largest land carnivores of all time, about 12 to 13 meters (40 to 43.3 feet) long, and 4.5-5 m (14-16.6 ft) tall, when fully-grown. Mass estimates have varied widely over the years, from more than 7,200 kilograms (8 short tons to as much as 7.5 tons).

The largest known T. rex skulls measure up to 1.5 m (5 ft) in length. Compared to other theropods, the skull was heavily modified. The skull was extremely wide posteriorly, with a narrow snout, allowing some degree of binocular vision. Some of the bones, such as the nasals, were fused, preventing movement between them.
