A comparison of the sizes of various microorganisms, cells, and viruses

Microorganisms are so small compared to humans that you might be tempted to think that they’re all about the same size. As this video shows, that is not at all the case. The rinovirus and polio virus are 0.03 micrometers (μm) wide, a red blood cell is 8 μm, a neuron 100 μm, and a frog’s egg 1 mm. That’s a span of 5 orders of magnitude, about the same difference as the height of a human to the thickness of the Earth’s atmosphere.
