Ankylosaurus Size Comparison
Ankylosaurus 3D Viewer pairs published armored figures with a 1.8 m person on screen - length about 6.25 m, hip height about 1.7 m, and weight about 4.8 tonnes (4800 kg) - so the club-tailed scale gap stays readable at a glance.
Ankylosaurus published figures
The Ankylosaurus facts panel and this table use the same commonly cited peer-reviewed measures for incomplete specimens, with the NHM alternate listed where it differs:
| Measure | Figure | Vs a 1.8 m person |
|---|---|---|
| Length | about 6.25 m (Carpenter-scale context); NHM also lists about 8.0 m | ~3.5x a person end-to-end at the 6.25 m figure |
| Hip height | about 1.7 m (common reconstructions) | ~0.9x adult standing height; model uses this for Size vs human |
| Weight | about 4800 kg / 4.8 tonnes; peer-reviewed estimates often about 4.8-8 t (NHM lists 8000 kg) | facts panel shows about 4.8 t; literature carries a wider range |
| When it lived | 68-66 million years ago | Late Cretaceous; herbivore; Barnum Brown 1906 Hell Creek, Montana; described 1908 (A. magniventris) |
How the Ankylosaurus size-vs-human toggle stays honest
The Ankylosaurus model is drawn to a fixed on-screen length so it fits the canvas; the Size vs human control then places a 1.8 m person at the true length-to-hip-height ratio for the about 6.25 m figure (hip height about 1.7 m). Tap Size vs human under the canvas to show or hide the scale figure - the comparison is proportional, not a decorative sticker.
What a person would see beside an Ankylosaurus
What a person would see is a low, armored quadruped whose hip line sits near adult head height: at about 1.7 m at the hip, an Ankylosaurus stands slightly under a 1.8 m person's full standing height, with armor studs and a bony club at the tip of the tail. From snout to club the animal spans about 6.25 m - turn on the person in the viewer and orbit beside a hind leg to feel how the armored back and clubbed tail sit relative to the scale figure.
What the Ankylosaurus size numbers are not
What these size numbers are not is a claim of certainty across every source: the Ankylosaurus size comparison uses commonly cited peer-reviewed estimates (about 6.25 m / about 4.8 t) while disclosing that NHM also lists about 8 m / 8 t and wider ranges appear in the literature; skin and color are an artistic reconstruction, this is a North American Late Cretaceous armored herbivore - not a franchise movie redesign, and no free-licensed Ankylosaurus glTF is re-hosted yet so the viewer stays procedural.

Other dinosaurs to compare
Other dinosaurs in the collection make useful size comparisons too: Ankylosaurus is a shorter armored herbivore, so for a plated Late Jurassic herbivore of similar ground-hugging build, see the Stegosaurus 3D Viewer, or for a horned quadruped herbivore, see the Triceratops 3D Viewer.
