What is the maximum size of a row?

This table specifies the maximum sizes and numbers of various objects defined in Microsoft SQL Server databases, or referenced in Transact-SQL statements. The table does not include Microsoft SQL Server 2000 Windows® CE Edition.

SQL Server Maximum Capacity Specifications

1 Network Packet Size is the size of the tabular data scheme (TDS) packets used to communicate between applications and the relational database engine. The default packet size is 4 KB, and is controlled by the network packet size configuration option.
2 The maximum number of bytes in any key cannot exceed 900 in SQL Server 2000. You can define a key using variable-length columns whose maximum sizes add up to more than 900, provided no row is ever inserted with more than 900 bytes of data in those columns. For more information, see Maximum Size of Index Keys.
3 The data portion of a database cannot exceed 2 GB in size when using the SQL Server 2000 Desktop Engine (MSDE 2000) or the Microsoft Data Engine (MSDE) 1.0. The total size of the database, including log files, can exceed 2 GB provided the sum of the sizes of the data files remains 2 GB or lower.
4 Database objects include all tables, views, stored procedures, extended stored procedures, triggers, rules, defaults, and constraints. The sum of the number of all these objects in a database cannot exceed 2,147,483,647.
