That one is not really possible. There is no internal functionallty that does
that and macros do not operate while a cell is in edit mode.

The best options that I can give you are to use a non-proportional font like
courier new where every character is the same size and then just size your
cell accordingly. The other option would be to use a text box where you will
have greater control over the data entry.

to show how many characters have been typed as they type.
