Personal note: See my SQL Monitor project
SELECT SCHEMA_NAME(so.schema_id) AS schemaname, OBJECT_NAME (sc.[id]) tablename
, COUNT (1) nr_columns
, SUM (sc.length) maxrowlength
FROM syscolumns sc
join sys.all_objects so on sc.[id] = so.[object_id]
--join sys.schemas s on so.schema_id = s.schema_id
WHERE so.is_ms_shipped = 0
GROUP BY so.schema_id, OBJECT_NAME (sc.[id])
ORDER BY SUM (sc.length) desc
