Dust particle
Dust is a mixture of tiny solid particles from sources such as soil, fibres, skin and pollen. Its particles vary widely in material and size.

A little perspective
Dust particle vs Cell: length comparison
The characteristic size of a dust particle is approximately equal to the diameter of a cell.
Dust is a mixture of tiny solid particles from sources such as soil, fibres, skin and pollen.
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions.

Dust particle
Characteristic size: 10 µm; representative.
A chosen 10 µm particle. Dust is a mixture, not a single size or material.
University of Utah — Cell size and scale
The marked characteristic size is calibrated. Unmeasured illustration details are representative.
Cell
Diameter: 10 µm; example.
A 10 µm diameter teaching example, not a universal cell size.
Defined examples — our methodology
The marked diameter is calibrated. Unmeasured illustration details are representative.

Why this measurement?
Why we use 10 µm
We compare the characteristic size of a dust particle. This is a representative comparison value; individual specimens or conditions can vary.
