avg_row_length for index ?

Is there a way to figure out the average row length of an index ?

I looked dba_indexes and index_stats, there is no such information.

I could use avg_col_len in dba_tab_columns plus whatever is needed for rowid to guess it out. But is there a more reliable and more direct way to get this information ?
