Maximum length of a varchar field in SQL Server?

12,500 is the maximum length of a varchar field. The nVarchar field has the same limitation however you will use twice the data store space with an nVarchar as it is effectively the same as a varchar with the exception that it will store data required for international character sets. If you support a multi-language system then you will want to use a nVarchar character type for these fields.
