Calculating the average row length

Hello experts,

I am trying to conduct a sizing exercise for my database.  I am using the tried and tested approximation that a table size is approx = num rows * average row length.

The problem is that I am struggling to figure out the average row length for the table(s).  From business predictions I can figure out the number of rows but without the avg row length I'm stuffed.

I know in Oracle I can (after running stats) select DBA_TABLES.AVG_ROW_LENGTH for just this thing - is there an easy way in SQL Server.  I have a development database which I can use for test data if only I can figure out how to do it.

Can anybody help

Regards, Meowsh
