Socket size chart for metric and standard

Sockets come in many sizes and can get confusing with what is bigger than the other. In this post, you will find a socket size chart for both metric and standard (SAE), in their respective order of size. The three most common drive size types are 1/4″, 3/8″, and 1/2″. You can learn more about drive types here. Each drive type will carry from and up to a certain size socket until another drive type is needed.
