Both marked spans share one linear scale. Artwork keeps its proportions; poses and surface detail are illustrative.
A little perspective
Bohr radius has about 1.06 times the length of 50 picometres.

Bohr radius
A characteristic length in a model of hydrogen. It is not the fixed radius of every atom.
NIST — 2022 CODATA fundamental constants
The marked length is calibrated. Unmeasured illustration details are representative.

Why these numbers?
The visual compares length with length. The records below preserve each value’s basis and caveats.

- Comparing
- Length ↔ Length
- Relative size
- Bohr radius is larger on this measurement by a factor of about 1.06. Bohr radius's selected measurement is approximately 5.84% greater than 50 picometres's.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Bohr radius is labelled measured constant; treat the displayed value as a comparison anchor rather than false precision.
