What are the size ranges of mammalian cells?

Posted August 6, 2018


Most mammalian cells are between 10 and 100 µm in diameter.

HeLa cells are normally 20 - 40 µm in diameter depending on the culture conditions. Red blood cells, one of the smallest human cells, have a diameter of ~8 µm. Muscle fiber cells and neurons on the other hand can be extremely large.
