+**Particle size** is the physical dimension of individual particles within a sample. This fundamental property profoundly influences a material's behavior, from its [Surface Area](/wiki/surface_area) to its interaction with light and flow. Understanding [Particle Distribution](/wiki/particle_distribution) is crucial across disciplines.
