Animal Size Comparison

Choose two or more animals—or open a popular comparison—then view them together in centimetres, inches, or feet.

For land animals we use shoulder height with all four feet on the ground—the usual wildlife listing—not crown or tip-of-horn height (so a giraffe looks shorter here than "how tall is a giraffe" headlines). Whales, dolphins, sharks, and reptiles like crocs use body length. Each card shows which measure applies.

Among living animals in this list, the blue whale is by far the longest. Open Blue whale vs megalodon or Blue whale vs orca to feel that scale next to another ocean giant.

Among living bears, polar bears and Kodiak bears are the largest. Polar bears often edge out on mass and length; Kodiaks are among the tallest at the shoulder. Compare them here with grizzlies and black bears.

A typical adult orca is longer and much heavier than a great white. Use the Orca vs great white shortcut, or open the ocean animal size guide for more whale and shark pairings.

Both are stout mustelids, but a wolverine usually stands taller at the shoulder and weighs more. The Wolverine vs honey badger shortcut puts typical adults side by side.

Shoulder height can overlap, but Beagles usually weigh more while Maine Coons often look longer in the body. Use the Maine Coon vs Beagle shortcut, or open the Maine Coon size guide for more breed pairings.

A mature billy goat often stands slightly taller at the shoulder than a typical sheep, but breed matters. Billy goat vs sheep is the quickest shortcut; the farm animal guide covers more livestock pairings.

Figures are typical adult mid-range values for relative size. Real animals vary by sex, age, and region—use them to understand scale, not as a veterinary measurement.

Megalodon is extinct. Fossil estimates usually fall around 14–24 metres long. We use a commonly cited large-adult figure and mark it approximate so it is not confused with a measured living animal.

Yes. After you pick a lineup, share the link so others open the same animals.
