Both marked spans share one linear scale. Artwork keeps its proportions; poses and surface detail are illustrative.
A little perspective
The length of 2 nanometres and the helix diameter of DNA double helix are approximately the same.

DNA double helix
A 2 nm diameter scale for B-form double-stranded DNA. The pictured strand length is illustrative, not the selected measurement.
University of Utah — Cell size and scale
The marked helix diameter is calibrated. Unmeasured illustration details are representative.
Measurement details
Why these numbers?
The visual compares length with helix diameter. The records below preserve each value’s basis and caveats.

- Comparing
- Length ↔ Helix diameter
- 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.
- DNA double helix is labelled representative; treat the displayed value as a comparison anchor rather than false precision.
