Char(1) And Char(2) Take Same Space?

I create two tables:

create table table1
(
col1 char(1)
)

go

create table table2
(
col2 char(2)
)

go

I add some records to two tables after createing operation completed.

Then i use dbcc page command to oversee the structures of data page in two tables.
I found some interest things:
The rows in two tabes take up same space:9 bytes

You can see the "9" on top of the data, for example:Slot 0, Offset 0x60, Length 9, DumpStyle BYTE
or calculate from the offset array



Any suggestions?
