I use this chunk of code at least once a week. It gives you a quick and easy reference on how big your tables are. This is about as accurate as the system stored procedure sp_spaceused (since it uses the same base tables), but it's handier, since it runs on all the tables in a database, and you can order it by whichever column you want.
Enjoy!
select TableName = convert(varchar(100),sysobjects.name) ,TotalRows = max(sysindexes.rows) ,MbData = floor(sum(convert(real,sysindexes.dpages)) * spt_values.low / 1048576) ,MbTotal = floor(sum(convert(real,sysindexes.used)) * spt_values.low / 1048576 ) from sysobjects join sysindexes on sysobjects.id = sysindexes.id join master.dbo.spt_values spt_values on spt_values.number = 1 and spt_values.type = 'E' where sysobjects.type = 'U' and indid in (0,1,255) group by sysobjects.name ,spt_values.low order by 4 desc
