Which one is Dylan Sprouse and which cole?

You're likely referring to the Sprouse twins, Dylan and Cole. It can be difficult to tell them apart! Here's a way to differentiate them:

* Dylan Sprouse: He is generally considered to be the slightly taller of the two. He often has longer hair, and some people say his face is slightly more defined.

* Cole Sprouse: He's generally considered the slightly shorter of the two. He often has shorter hair.
