Size is the fastest way to rule methods in or out. Find your range on the scale — where two methods overlap, the questions below decide.

Dynamic light scattering (DLS) 0.8 nm – 6500 nm

Nanoparticles, emulsions, proteins, inks

Laser diffraction (LD) 10 nm – 5 mm

Powders, suspensions, sprays, cement

Dynamic image analysis (DIA) 0.8 µm – 135 mm

Granules, pellets, abrasives, coffee, seeds — and particle shape

Sieve analysis 10 µm – 125 mm

Coarse material, existing sieve specifications

Logarithmic scale. Ranges are instrument maxima across the respective product family; the usable range for your material may be narrower.
