What contains more small pieces or particles of sugar granulated sugar or powdered sugar?

Powdered sugar contains more small particles than granulated sugar because it is finely ground and has a much smaller particle size. While granulated sugar consists of larger, coarser crystals, powdered sugar is essentially granulated sugar that has been processed into a fine powder, resulting in a higher number of smaller particles by volume. Consequently, if you compare equal volumes of both, powdered sugar will have a greater quantity of tiny sugar particles.
