A little perspective
Climbing piton vs Human brain: length comparison
The overall length of a climbing piton is approximately equal to the front-to-back length of the human brain.
A climbing piton is a metal spike driven into rock cracks to provide protection or anchor points during climbing.
The human brain is the organ that processes sensory information and coordinates thought, memory, movement and many body functions.
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions.

Climbing piton
Defined overall length: 15 cm; defined specimen; range 10 cm–20 cm.
A defined forged-steel angle piton 15 cm long and 90 g. Pitons vary by crack type and manufacturer; overall length includes the eye and excludes a separate carabiner or hammer.
Defined examples — our methodology
The marked defined overall length is calibrated. Unmeasured illustration details are representative.
Human brain
Representative front-to-back length: 15 cm; defined specimen; range 14 cm–17 cm.
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.

Why this measurement?
Why we use 15 cm
We compare the overall length of a climbing piton. This is an illustrative comparison value, not a claim that every example is the same. The recorded range is 10 cm to 20 cm.
A defined forged-steel angle piton 15 cm long and 90 g. Pitons vary by crack type and manufacturer; overall length includes the eye and excludes a separate carabiner or hammer.
