SR.NO.	CHAR	VARCHAR
1.	CHAR datatype is used to store character string of fixed length	VARCHAR datatype is used to store character string of variable length
2.	In CHAR, If the length of string is less than set or fixed length then it is padded with extra memory space.	In VARCHAR, If the length of string is less than set or fixed length then it will store as it is without padded with extra memory spaces.
3.	CHAR stands for “Character”	VARCHAR stands for “Variable Character”
4.	Storage size of CHAR datatypes is equal to n bytes i.e. set length	Storage size of VARCHAR datatype is equal to the actual length of the entered string in bytes.
5.	We should use CHAR datatype when we expect the data values in a column are of same length.	We should use VARCHAR datatype when we expect the data values in a column are of variable length.
6.	CHAR take 1 byte for each character	VARCHAR take 1 byte for each character and some extra bytes for holding length information
9.	Better performance than VARCHAR	Performance is not good as compared to CHAR
