The selected measurement follows the object’s longest or specifically defined linear direction.
The physical boundary or individual size can change. Vastoscope uses a documented reference value to make comparison possible.
Vastoscope compares the SI value in metres for this representative body length. A ratio is mathematically valid as a linear span, while the interface identifies when the two selected definitions differ.
Familiar scale bridges
These anchors are selected by logarithmic proximity from familiar human, engineered, planetary and cosmic references.
A representative adult human — the central reference point for moving both inward and outward.

Evidence trail
Vastoscope keeps the displayed number separate from its measurement type and certainty. Representative and model-dependent values are intentionally labelled instead of presented as exact edges.
