Both marked spans share one linear scale. Artwork keeps its proportions; poses and surface detail are illustrative.
A little perspective
The characteristic size of Pollen grain is about 1.5 times the length of 20 micrometres.

Pollen grain
A chosen 30 µm pollen grain. Plant species produce very different grains.
University of Utah — Cell size and scale
The marked characteristic size is calibrated. Unmeasured illustration details are representative.

Why these numbers?
The visual compares length with characteristic size. The records below preserve each value’s basis and caveats.
Pollen grain
30 µmCharacteristic size · representative
A chosen 30 µm pollen grain. Plant species produce very different grains.
- Comparing
- Length ↔ Characteristic size
- Relative size
- Pollen grain is larger on this measurement by a factor of about 1.5. Pollen grain's selected measurement is approximately 50% greater than 20 micrometres's.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Pollen grain is labelled representative; treat the displayed value as a comparison anchor rather than false precision.
