Giganotosaurus was one of South America's largest predators. A representative reconstruction reaches about 13 m, putting it close to T. rex in length but with a different, lighter-built skull and body.

What 13 metres feels like
Thirteen metres equals about 7.6 reference-human heights. Its hip line would sit around the height of a single-storey roof.
More than one number
Length, height and body mass
It may have been slightly longer than many T. rex specimens, while estimates around 7.2 tonnes make it lighter than the largest tyrannosaurs.

How certain is this size?
No complete skeleton is known. Missing portions must be reconstructed from related carcharodontosaurids, so both length and mass should be read as representative estimates.
Why compare it
The question this animal answers
Giganotosaurus separates cinematic reputation from anatomy: it is a close length rival to T. rex, but the fossil record does not support a simple winner in every dimension.
