1 (or 2) byte(s) + length of data. As far as I know if record is updated, it is always written into the new space in database file (regardless of longer or shorter varchar or char values). So no need to worry...

I do not insist on 255, I just thought there is no need for artificial limitations such as 32 or 64 or 80 :)
