Animal Height Comparison

This animal height comparison chart puts animals side by side and against a person, all drawn to the same scale, so you can see how they measure up. From a 0.85-metre gray wolf to a 5.5-metre giraffe. Free on LK Forge — no sign-up.

Scroll sideways if figures run off the edge. The ruler fits the tallest figure.

How the comparison works

Every animal is drawn at the same scale — a fixed number of pixels per metre — so the chart is a true side-by-side comparison. The ruler automatically fits the tallest figure, so adding the giraffe rescales everything below it. Add yourself as a person to feel just how big these animals really are.

Where the heights come from

Heights are nominal, widely-cited figures for a typical adult animal — measured at the shoulder or withers for four-legged animals, and full standing height for others (a rearing polar bear, a standing gorilla). Individuals vary, so treat them as good round reference points rather than records.

Frequently Asked Questions

How does the height comparison chart stay to scale?
The ruler axis automatically fits the tallest figure on the chart, and every figure is drawn at the same pixels-per-metre scale. So when you add something very tall, everyone else shrinks to match — the proportions between figures always stay true. Very short figures keep a small minimum size so they never disappear entirely.
What can I compare on this page?
This page lets you compare a gray wolf (0.85 m), emperor penguin, lion, red kangaroo, horse, gorilla, moose, ostrich, polar bear, African elephant, T. rex and a 5.5 m giraffe — plus people for scale. Add your own people by name and height too.
Can I switch between centimetres and feet and inches?
The unit toggle on this animal height comparison flips the whole chart, the ruler and every label between metric (cm / m) and imperial (feet and inches). When adding a height you can type it either way — for example 178 cm, 1.78 m, or 5'10 — and it is converted automatically. A bare number is read in whichever unit is active: inches in imperial, and in metric anything above 3 is treated as centimetres while anything smaller is read as metres. Every height is stored internally in metres, so switching units only relabels the chart and never rounds or alters the figures you added.
Where do the silhouettes come from?
The animal silhouettes are real vector artwork released into the public domain or under Creative Commons Zero — the wolf, lion, kangaroo, horse, gorilla, moose, ostrich, polar bear, elephant, giraffe and T. rex come from PhyloPic contributors, and the human figures used for scale come from Wikimedia Commons. Every artist is credited by name in the silhouette credits section at the bottom of this page, with a link to the licence. Buildings on the companion page use the tool's own drawn shapes rather than third-party artwork. Each silhouette keeps a fixed aspect ratio as it is scaled, so an animal drawn small has exactly the proportions it has when drawn large.
Is my data saved or uploaded anywhere?
Nothing from this animal height comparison is uploaded. The figures you add are stored only in your own browser using localStorage, so they are still there when you come back on the same device, and clearing them removes them completely. Your unit preference is saved the same way, in a separate key. There is no account and no server behind the chart, so your list does not follow you to another browser or another device.
