In SQL Server specifically, does Varchar(50) take same amount of space as Varchar(MAX)?

Question

For example, if I wanted to store a 20 byte character string, would a VARCHAR(50) field use the same space as a VARCHAR(MAX) field ?

Answer 1

Varchar(50) stores a maximum of 50 characters. Varchar(max) stores a maximum of 2,147,483,647 characters. But, varchar(50) keeps the 50 character space even if you don't store 50 characters. but varchar(max) is flexible to any size. size doesn't matter.
