The size of the colloidal particles though is bigger than particles of true solutions, but is smaller than the size of suspension. We know that the particles in a colloid show continuous random zigzag motion called brownian motion. This brownian motion counters the force of gravity acting on colloidal particles and helps in providing stability to colloidal sols by not allowing them to settle. The fact that colloidal particles are charged and repel each other also contributes to colloidal particles not settling down, even after being left undisturbed for a long time.

A colloid is a substance in which microscopic particles are dispersed in a medium, but are not dissolved in it. ... A suspension is similar to a colloid except that the dispersed particles tend to be larger and will eventually settle or form sediment.
