The key difference between varchar and nvarchar indicates how data are stored in a database. â¢ Varchar stores ASCII values and nvarchar stores Unicode characters. â¢ Varchar uses one byte per character while nvarchar uses two bytes per character.
If the number of characters entered in an NCHAR data type column is less than the specified column length, spaces are appended to it to fill up the whole length. Another difference is in the storage size wherein the storage size for NCHAR is two times n bytes while for NVARCHAR is two times the number of characters entered (in bytes). You should use NCHAR data type when the data values in a column are expected to be consistently close to the same size.
