What causes raindrops to be different sizes?

I ask because when it rained today, I looked up at a streetlight and saw that rain was coming down in sheets though I was barely getting wet. What makes these drops so small as compared to when it rains and the drops are huge and get you soaked?

A raindrop gets bigger in the cloud by combining with other drops, also called coalescence. Coalescence happens in the air, and the cloud, so the raindrops that combine in the air, are larger than the ones that don't.
Another reason why raindrops vary in size is because a raindrop can be ripped into pieces on a windy day, creating tiny droplets of water that fall to the ground.
Hope this helped :)
