Velociraptor Size Comparison
The Velociraptor 3D Viewer shows a small dromaeosaurid at published turkey scale: length about 2 m, hip height about 0.5 m, weight about 15-20 kg. Turn on Size vs human and a 1.8 m person appears at the true length ratio, so the film-versus-fossil gap is readable at a glance.
Velociraptor published figures
These are real published measures, given as a range where sources disagree:
| Measure | Figure | Vs a 1.8 m person |
|---|---|---|
| Length | about 2 m (range 1.5-2 m) | ~0.8x to ~1.1x a person end-to-end; model uses representative ~2 m |
| Hip height | about 0.5 m | ~0.3x adult standing height |
| Weight | about 15-20 kg | roughly a large turkey, not a human-mass predator |
| Sickle claw | more than 6.5 cm outer curve | second toe of each foot; function still debated |
| When it lived | 75-71 million years ago | Late Cretaceous, Gobi Desert, Mongolia |
What the on-screen facts panel shows next to this table
The facts panel beside the Velociraptor canvas is deliberately shorter than the table above, and it carries one representative figure per row rather than a range: Length 2 m, Weight 18 kg, When it lived 75-71 Mya (Late Cretaceous), Diet Carnivore, and Described - 1923, Gobi Desert, Mongolia (named by Osborn, 1924). There is no hip-height row in the panel, so the about 0.5 m figure lives here in the table instead. Below the rows the panel repeats the claw and feather notes: a sickle-shaped claw over 6.5 cm long tipped the second toe on each foot, and a 2007 fossil find showed quill knobs, evidence of feathers this model does not render. It closes by naming the model as an artistic reconstruction and crediting its author, because fossils do not preserve soft tissue or color.
How the Velociraptor size-vs-human toggle stays honest
The Velociraptor model is normalised to a fixed on-screen length so that any species fits the canvas the same way. Size vs human then scales the 1.8 m figure by the same units-per-metre factor derived from the representative 2 m length, which is why the person ends up at the true ratio rather than at a guessed one. Tap Size vs human under the canvas to show the figure, and the button flips to Hide human to put it away. The comparison is proportional, not a decorative sticker.
What a person would see beside a Velociraptor
What a person would see is how much smaller it really is: at about 0.5 m at the hips, a Velociraptor hip joint sits well below a 1.8 m person's waist. From snout to tail the animal spans roughly 2 m, so it is closer to a large turkey than to the human-sized predator of the films. Turn on the person in the viewer and orbit beside a hind leg to feel the difference.
The four Velociraptor controls under the canvas
Open the Velociraptor 3D Viewer and the status line reports its own progress. It first reads that the 3D engine is loading, about 0.7 MB, one time and then cached; once the scene is live it switches to drag to rotate, scroll or pinch to zoom, click a body part for a fact. Drag with the pointer to orbit, and use the scroll wheel or a two-finger pinch to zoom. Four controls sit under the canvas:
- Fullscreen - expands the wrapper around the scene, so the buttons stay visible instead of disappearing with the page
- Stop rotation / Auto-rotate - freezes the auto-spin, then resumes it
- Idle motion / Stand still - adds subtle breathing and leg sway, then holds the pose
- Size vs human / Hide human - shows or hides the 1.8 m scale figure described above
Part inspection is a short click rather than a drag: the viewer only treats a press as a click when the pointer travelled under about 8 pixels, so an orbit never fires a part note by accident. Clicking the head, the neck, the body, an arm, a leg, or the tail swaps the panel for a note on that part, and clicking empty space returns to the fact sheet. The arm note is a good example of the tone: short but strongly muscled, with the number of fingers known from the fossil hand.
The in-browser viewer against phone AR apps and museums
These rows compare what the Velociraptor viewer actually ships against typical phone AR apps, a museum hall visit, and a still photo:
| Aspect | In-browser 3D viewer | Phone AR app | Museum / static image |
|---|---|---|---|
| Install / download | 0 MB app install; the engine is vendored and cached after first load | Often 50 to 500 MB store download | Travel time; or 0 MB for a photo |
| Time to first view | Seconds - one page load; engine lazy-loads after paint | Minutes - install, permissions, tracking setup | Hours for a visit; instant for a photo |
| Place in a physical room | No - orbit on a flat screen only | Yes - true AR placement when tracking works | Hall scale in person; none in a photo |
| Desktop without a phone | Yes - current browser with WebGL | Usually no | Photo yes; museum no |
| Published size figures on hand | Yes - about 2 m length, hips about 0.5 m, about 15-20 kg, 75-71 Mya | Varies by app | Labels vary; photo rarely carries full sheet |
| Reconstruction honesty | Artistic skin; feathers are not rendered despite the 2007 quill-knob evidence | Often sells film-scale raptor skins | Bones are real; color still interpretive |
Two details behind the first two rows are worth knowing. The engine is fetched after the page paints rather than before, so the layout and the numbers are readable while the 3D scene is still arriving, and the browser keeps it cached for later visits. A first-paint shape of the animal is drawn immediately, then a real published model, about 0.29 MB and released under CC0 by Quaternius, replaces it when available; the status line changes to say it is showing a real 3D model of this species. If a device has WebGL turned off the scene cannot draw, and the page says so plainly while the facts panel keeps working, so the measurements are never locked behind the graphics.
Everything runs on your device, so there is no account and nothing about the visit is sent to a server - which is what makes it usable on a locked-down classroom laptop. Pick a phone AR app instead when you need the silhouette standing on your own floor, since this viewer never claims room placement. A museum wins for walking beside mounted dromaeosaur bone at hall scale, where the real sickle claw is small enough to be easy to miss. A static image wins only when you need one shareable frame with no interactivity.
What the Velociraptor size numbers are not
These are published bone-based estimates carrying an honest range, not precision measurements of one animal. Skin color is an artistic reconstruction, the model does not render feathers even though the 2007 quill knobs are real evidence for them, and the sickle claw's use stays debated - neither the viewer nor this guide asserts a film-style killing method for it. The viewer is a screen-based model: it does not place the animal in your room, does not claim soft-tissue accuracy, and is not a ranking of commercial AR brands.
Other dinosaurs to compare
Other dinosaurs in the collection make useful size comparisons too: Velociraptor is a small, agile theropod, so for a similarly fast runner at larger scale, see the Gallimimus 3D Viewer, or for the giant apex predator at the opposite end of the size scale, see the Tyrannosaurus rex 3D Viewer.
