Gregory S. Paul estimates Carcharodontosaurus iguidensis at 10 m (33 ft) and 4 t (4.4 short tons). It is currently known to include two species,C.saharicus andC.iguidensis, which were among the larger theropods, slightly bigger thanTyrannosaurus and possibly slightly larger thanGiganotosaurus, but not quite as large asSpinosaurus.
