Qianzhousaurus were medium-sized tyrannosaurids that have been estimated to be 6.3 m (21 ft) long and 757 kg (1,669 lb) in weight.
The taxon can be differentiated from other tyrannosaurids in having a highly narrowed premaxilla, a pneumatic opening on the upper extension of the maxilla, and the lack of a vertical ridge-like structure on the lateral surface of the ilium.

Unlike more "traditional" tyrannosaurids, which had prominent deep-set jaws and thick teeth, Qianzhousaurus had a particularly elongated snout, with (when restored) narrow teeth.
The holotype specimen is notably more larger and mature than the holotypes of both species of Alioramus, however, given that some sutures between the cervical and dorsal vertebrae are partially fused, the holotype was a immature animal, likely a sub-adult.
Qianzhousaurus were leggy animals with a 70 cm (700 mm) long femur and 76 cm (760 mm) long tibia.
