Titanoboa Size Comparison
Titanoboa 3D Viewer pairs Head et al. 2009 snake figures with a 1.8 m person - length about 12.8 m mean (up to about 14.3 m), mass about 1135 kg mean - so the scale gap stays readable at a glance.
Titanoboa published figures
The Titanoboa facts panel and this table use the same real published measures (a range where sources disagree):
| Measure | Figure | Vs a 1.8 m person |
|---|---|---|
| Length | about 12.8 m mean (up to about 14.3 m; Head et al. 2009) | ~7.1x a person end-to-end at the mean; Size vs human uses 12.8 m |
| Mid-body height | about 0.7-1.0 m (panel 0.8 m; proportionate estimate, not a published hip height) | shorter than adult standing height |
| Weight | about 1135 kg mean (about 730-1819 kg range; Head et al. 2009) | many times a human body mass |
| When it lived | about 60-58 million years ago | Paleocene; Cerrejon Formation, Colombia |
| Group | Giant boid snake (T. cerrejonensis) | not a dinosaur |
How the Titanoboa size-vs-human toggle stays honest
The Titanoboa 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 ratio to the catalogue 12.8 m mean (within the published range up to about 14.3 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 a Titanoboa
What a person would see is a scale gap of roughly seven body lengths: from snout to tip a mean Titanoboa spans about 12.8 m, about 7.1 body lengths of a 1.8 m person laid end to end. Turn on Size vs human and orbit beside the mid-body to feel how far the coils extend past the scale figure while the animal sits on the water plane.
What the Titanoboa size numbers are not
What these size numbers are not is a land-dinosaur estimate: the Titanoboa size comparison uses published bone-based estimates for a giant snake - not a dinosaur - and soft-tissue color in the viewer is still an artistic reconstruction. For the control walkthrough see how to view Titanoboa in 3D. For trade-offs versus phone AR apps see Titanoboa 3D viewer vs AR apps.
Other animals to compare
Other animals in the collection make useful size comparisons too: Titanoboa is a snake rather than a land dinosaur, so for another non-dinosaur marine carnivore of similar overall length, see the Mosasaurus 3D Viewer.
Why trust these tools
- Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
- No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
