Oracle 9i and null values

Hi all,

I have a question regarding null values in tables. In the db-handbook it is said, that null values at the end of a row do not consume disk space at all as the header of the next row indicates the beginning of a new entry.

But what is with null values somwhere else in a table? How much disk space does such a null value consume? If have a table with lots of null values and would like to know how valuable it is to redesign the structure to save disk space.

Best regards,
