This is a super handy script that can be found in original source here: http://www.keyboardface.com/archives/2007/06/12/mssql-table-size-for-all-tables/

It basically lists all the tables with their sizes on your db

declare @RowCount int, @tablename varchar(100)
declare @Tables table (
PK int IDENTITY(1,1),
tablename varchar(100),
processed bit
)
INSERT into @Tables (tablename)
SELECT TABLE_NAME from INFORMATION_SCHEMA.TABLES where TABLE_TYPE = 'BASE TABLE' and TABLE_NAME not like 'dt%' order by TABLE_NAME asc

declare @Space table (
name varchar(100), rows nvarchar(100), reserved varchar(100), data varchar(100), index_size varchar(100), unused varchar(100)
)
select top 1 @tablename = tablename from @Tables where processed is null
SET @RowCount = 1
WHILE (@RowCount <> 0)
BEGIN
insert into @Space exec sp_spaceused @tablename
update @Tables set processed = 1 where tablename = @tablename
select top 1 @tablename = tablename from @Tables where processed is null
SET @RowCount = @@RowCount
END

update @Space set data = replace(data, ' KB', '')
update @Space set data = convert(int, data)/1000
update @Space set data = data + ' MB'
update @Space set reserved = replace(reserved, ' KB', '')
update @Space set reserved = convert(int, reserved)/1000
update @Space set reserved = reserved + ' MB'

select * from @Space order by convert(int, replace(data, ' MB', '')) desc
