Type varchar mysql limit

Question

Can anyone explain what the varchar limit is? I read the following:

a Mysql database has a limit of 65,535 bytes (for the entire line)

However, how byte counting is performed?

My initial thought is that the count is performed by adding to other varchar type fields.

Rohan, the account considers all columns except the columns of blob and text types. See details in the Mysql documentation: Limits on Table Column Count and Row Size.
