Both marked spans share one linear scale. Artwork keeps its proportions; poses and surface detail are illustrative.
A little perspective
The length of 15 centimetres and the representative front-to-back length of Human brain are approximately the same.

15 centimetres
The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.
Human brain
A defined adult-brain specimen 15 cm front to back and 1.4 kg. Brain size and mass vary by person; these values are comparison anchors, not health benchmarks.
Defined examples — our methodology
The marked representative front-to-back length is calibrated. Unmeasured illustration details are representative.
Measurement details
Why these numbers?
The visual compares length with representative front-to-back length. The records below preserve each value’s basis and caveats.

A defined adult-brain specimen 15 cm front to back and 1.4 kg. Brain size and mass vary by person; these values are comparison anchors, not health benchmarks.
- Comparing
- Length ↔ Representative front-to-back length
- Relative size
- The two selected measurements are approximately equal.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Human brain uses a 15 cm central value within a recorded range of 14 cm–17 cm.
- Human brain is labelled defined specimen; treat the displayed value as a comparison anchor rather than false precision.
- The recorded ranges overlap, so the ordering can vary even though the central values differ.
