What is the diameter of human red blood cell?

The discocyte shape of human RBCs is approximately 7.5 to 8.7 μm in diameter and 1.7 to 2.2 μm in thickness.

How do you calculate the diameter of a red blood cell?

The mean diameter of blood cells is determined by using the wave length of laser light λ = 632,2nm.

According to Rayleigh's expression (William Strutt) cell diameter d can be written as d = 1.22 λ/ tanθ. By replacing tanθ the equation for erythrocyte diameter d is obtained: d = n·λ·L/r 1.
