Human scale
What 1.7 metres feels like
This page is the baseline: one reference human equals 1.7 m from floor to crown. Every human count elsewhere on ScaleCheck divides an animal's representative length by this height.
More than one number
Length, height and body mass
The reference mass is 70 kg. It keeps weight ratios readable, but age, sex and population variation mean real people can differ substantially from this display setting.

Evidence boundary
How certain is this size?
Unlike a fossil reconstruction, the uncertainty here is a design choice rather than missing evidence. The values are deliberately rounded so comparisons stay consistent from page to page.
Why compare it
The question this animal answers
Metres become intuitive when the same person stands beside every subject. A 33 m blue whale is no longer an abstract number: it spans roughly nineteen of these reference heights.
