How does a capybara compare with a tarsier?
A capybara measures 1.2 m (3.94 ft) end to end, and a tarsier measures 28 cm (11 in) from the ground up. A capybara comes to 4.29 times the measured size of a tarsier, a difference of 92 cm (36.2 in). The two are not judged on the same axis: a capybara is quoted as a length and a tarsier as a height, so the honest statement is one figure against the other, 23% of it, and not one outline against another. A capybara is written in single metres and a tarsier in tens of centimetres, a whole band of scale apart.
| Object | Real size | Axis measured | What the figure covers |
|---|---|---|---|
| Capybara | 1.2 m 3.94 ft |
Length | Whole body or structure, end to end |
| Tarsier | 28 cm 11 in |
Height | Average Male |
Both figures, Capybara and Tarsier, come from the Size It Up measurement set, one real-world size and one measured axis per object, last checked in September 2026; outline provenance is listed on the sources page.
Why this one is hard to judge by eye
A capybara is drawn about 9.77 times as wide as a tarsier as well as 4.29 times its measured size, so the area it takes in the frame grows faster than the figure anyone quotes. Both shapes fit in a single glance here, which ought to make 4.29 to one obvious between a capybara and a tarsier, and it is not: at this size the eye compares whole outlines while the figures above compare one axis. On the drawing above a capybara is about 1.65 times as wide as it is tall and a tarsier about 2.28 times as tall as it is wide, so the two outlines fill the frame in ways that have nothing to do with the one axis being compared.
What each figure covers
Capybara. Capybaras are quoted head and body, without the tail, which barely exists on them. They are the largest rodent alive and about the size of a medium dog.
Tarsier. Tarsiers are measured head and body, tail excluded, and the tail is longer than the body. Their eyes are each larger than their brain.
A capybara is quoted as a length and a tarsier as a height: two conventions, so the ratio compares the two numbers rather than the two objects.
What else is about that size?
Measured the same way, Capybara at 1.2 m sits within two fifths of Magikarp at 90 cm, Alpine Ibex at 1.6 m and Koala at 78 cm. Tarsier at 28 cm has Papa Smurf at 27 cm, A4 Paper at 29.7 cm and Buzz Lightyear at 30 cm for company, within a tenth. Swapping any of those in for a capybara would move its ratio to a tarsier by less than 40%.
