Benson ''et al.'' (2012) estimated that ''Corythosaurus'' has an average length of {{convert|9|m|ft}}.<ref name="benson2012"/> In 1962, [[Edwin H. Colbert]] used models of specific dinosaurs, including ''Corythosaurus'', to estimate their weight. The ''Corythosaurus'' model used was modelled by Vincent Fusco, after a mounted skeleton, and supervised by Barnum Brown. After testing, it was concluded that the average weight of ''Corythosaurus'' was {{convert|3.82|t|LT ST|abbr=off|sigfig=3}}.<ref name="colbert1962">{{cite journal|last=Colbert|first=E.H.|year=1962|title=The Weight of Dinosaurs|url=http://digitallibrary.amnh.org/dspace/bitstream/handle/2246/3451//v2/dspace/ingest/pdfSource/nov/N2076.pdf?sequence=1|journal=American Museum Novitates|issue=2076|pages=1–16}}</ref> The total length of ''Corythosaurus'' specimen AMNH 5240 was found to be {{convert|8.1|m|ft|abbr=on}} long, with a weight close to {{convert|3.1|t|LT ST|abbr=off|sigfig=5}}.<ref name="seebacher2001">{{cite journal|last=Seebacher|first=F.|year=2001|title=A New Method to Calculate Allometric Length-Mass Relationships of Dinosaurs|url=http://dinoweb.ucoz.ru/_fr/4/A_new_method_to.pdf|journal=Journal of Vertebrate Paleontology|volume=21|issue=1|pages=51–60|doi=10.1671/0272-4634(2001)021[0051:ANMTCA]2.0.CO;2|citeseerx=10.1.1.462.255|s2cid=53446536 }}</ref> In 2016, Gregory S.

Proportionally, the skull is much shorter and smaller than that of ''[[Edmontosaurus]]'' (formerly ''[[Trachodon]]''), ''[[Kritosaurus]]'', or ''[[Saurolophus]]''. But, when including its crest, its superficial area is almost as large.<ref name="brown1914p561"/>
