varchar(max)

hi all,
i have a table with three columns.
First Col is defined varchar(50),Second col is defined char(50),Third col is varchar(max)
i inserted all colums a simple word like 'example'
and i wonder how many bytes each columns occupy on my table?
For eg second columns occupies 50 byte for each record.
Thanx in advanced

and also depends on if how the SET ANSI_PADDING is set on that table and if allows NULL or not on that column. So it could be net data size or use more space depending on the incoming data. char data type typically use more if PADDING in ON or not trimmed on the data source.

i know it depends on the length of the data but i can not explain question clearly.
I wanna to store Customers name on a table.I can select date type varchar(50) or Varchar(Max).
but i wonder what is the main differences between varchar(50) and varchar(Max)?
which one shoul be prefered when i store customers name? and why?

i still can not explain my question clearly I did not think to store customer name in a varchr(max) Coloum when i defined a column data type char(50) and insert frank to this column it occupies 50 byte
if i defined varchar (50) and insert frank to this column how many bytes does it occupies?
