For example, if D50=5.8 um, then 50% of the particles in the sample are larger than 5.8 um, and 50% smaller than 5.8 um. D50 is usually used to represent the particle size of group of particles. particle-size-distribution-d50.

Classification by Distribution of Grain Sizes.

Particle‐Size Distribution Curve.  The results of sieve and hydrometer analyses can be plotted to show the distribution of grain sizes.   Soils with an even‐distribution of grain sizes are called "well‐graded" and soils with predominantly one grain size are called "poorly‐graded" (see Figure 4 below).  Well‐graded soils, having a variety of particles sizes, can be packed "tighter" than poorly‐graded soils leading to higher unit weight and therefore higher strength and lower settlement potential.
