A little perspective
About 1.43 times the diameter of 70 µm hair.
70 µm hair: A hair is a slender strand of protein that grows from the skin of humans and other mammals.
Measurements, assumptions & sources +
Sheet of paper
A 0.1 mm thick sheet. Paper stock and compression change thickness.
Defined examples — our methodology
The marked thickness is calibrated. Unmeasured illustration details are representative.
70 µm hair
A 70 µm diameter example; hair thickness varies.
Defined examples — our methodology
The marked diameter is calibrated. Unmeasured illustration details are representative.

Why we use 100 µm
For comparison, this page uses thickness. This is labelled example: an explicit comparison model rather than a claim that every example has the same value.
