One way is to look at the sys.dm_db_index_physical_stats output. 

的min_record_size_in_bytes,max_record_size_in_bytes和avg_record_size_in_bytes会给你你想要的大小。

If you want to see the size of a particular record, another way is to find the physical row location, see 

SQL Server 2008: New (undocumented) physical row locator function.

然后,您可以转储行物理结构,看到记录的剖析。
