Tyrannosaurus was large, but 53 feet is ridiculous; Tyrannosaurus was probably up to 40 feet. Spinosaurus, Carcharodontosaurus, Giganotosaurus were probably larger than Tyrannosaurus. It might be possible that Mapusaurus, Saurophagnax, Tyrannotitan, and Acrocanthosaurus were rivaled or larger in size, but I do not have enough evidence to create a strong statement. Many other animals, such as Tarbosaurus,  were close to Tyrannosaurus's size, but not quite there.
