Red Blood Cell (RBC) Size Variation. Normal RBCs have a diameter of 6 - 8 μm. On a peripheral blood smear, normal RBCs are disc-shaped with a pale-staining central area called the central pallor. When judging red cell size on a blood smear, the classic rule of thumb is to compare them to the nucleus of a small normal lymphocyte. The normal ...
The head of a pin is about 2mm in diameter. Use this animation to compare the relative sizes of cells and organisms sitting on a pinhead. Nearly invisible without magnification, dust mites dwarf pollen grains and human cells. In turn, bacteria and viruses are even smaller.
There are normally between 4×10 9 and 1.1×10 10 white blood cells in a liter of blood, making up approximately 1% of blood in a healthy adult. This is also called leukocyte count and may be expressed as 4,000 to 11,000 cells per cubic millimeter (cmm). RBC Count. RBC count is the number of red blood cells in a volume of blood.
The size of red blood cells usually falls within a range of 6 to 8 micrometers in random blood samples that have been analyzed by laboratory testing. Mature forms of the red blood cells (RBCs) are called erythrocytes, which constitute around 40 to 45% of human red blood cells.
Eukaryotic cells are typically 10 times the size of prokaryotic cells (these cell types are discussed in the next Chapter). Plant cells are on average some of the largest cells, probably because in many plant cells the inside is mostly a water filled vacuole.

The shapes and sizes of cells span a large range as shown in Table 1. Size and shape, in turn, are intimately tied to the function of each type of cell. Red blood cells need to squeeze through narrow capillaries and their small size and biconcave disk shape achieve that while also maximizing the surface area to volume ratio.
Most animal cells are between 10 to 100 microns in size. The size depends partially on the type of cell and its function. Red blood cells, which don't need to divide and replicate are only about 8 microns in diameter, while many muscle and nerve cells are thin, spindly and extremely long.
