This diagram compares the approximate sizes of large and small aerosol particles with raindrops and cloud droplets. A typical cloud droplet is 20 microns in diameter, a large aerosol particle is 100 microns in diameter, a small aerosol particle is 1 micron in diameter, and a typical raindrop is 2 millimeters (2000 microns) in diameter.
