Web5 Dec 2024 · Bacterial cells are much smaller than human cells. Bacterial cells can measure from about 1 to 10 μm long. Most of them are only about 1 to 2 μm in diameter. 1 μm, or micrometre, is 1 000 times smaller than a millimetre. That is very tiny! It’s much smaller than the human red blood cell, which is (on average) about 7 μm in diameter. http://www.annualreport.psg.fr/hVUnjfH_bacterial-classification-structure-and-function.pdf
