Size: The main difference between a cloud drop and a raindrop is their size. Cloud droplets are typically much smaller than raindrops. Cloud droplets are usually less than 0.05 millimeters (0.002 inches) in diameter, while raindrops are typically between 0.5 and 6 millimeters (0.02 and 0.24 inches) in diameter.

Weight: Cloud droplets are much less massive than raindrops. A single cloud droplet weighs about one millionth of a gram, while a single raindrop can weigh up to hundreds of milligrams.

Speed: Due to their difference in size and mass, cloud droplets fall much more slowly than raindrops. Cloud droplets fall at speeds of about one centimeter per second (0.4 inches per second), while raindrops can fall at speeds of several meters per second (several feet per second).
