What is the smallest to biggest size for drive size for ratchet to socket because I know there's 3/8 and 1/4 and 1/2 either there any other sizes that I'm missing?

 

1/4
3/8
1/2
3/4
1

The 1/4, 3/8, and 1/2 are the most common. I've only seen the 3/4 and 1" for heavy trucks (dump trucks, 18-wheelers big) and heavy industry. For working on cars, I've never needed anything larger than 1/2" drive. The 3/8" is what I use the most.
