varchar(max) won’t take extra space.
One dangerous thing about varchar(max) is that someone can potentially but a huge amount of data in it. This can hurt if a malicious user. or faulty program, enters a 1MB address line. No client or web application will expect that, and it might cause them to crash.
So, as a best practice, create varchar fields with a specified maximum length.
