The maximum row size for the used table type, not counting BLOBs, is 65535. Now, however, you can go up to 65,535 characters on VARCHAR, so if you're still using '255. Explanation: Prior to MySQL 5.0.3 (give or take a few point releases - I forget) a VARCHAR column could be 255 characters in length maximum, so VARCHAR (255) was often used as a default. `f1` varchar(32766) NOT NULL, //INCREASED LENGTH BY 1 Because 255 is now just an arbitrary choice for a VARCHAR length. Total length will be 32765+2(for storing length) + 32766 + 2 = 65535.ĬREATE TABLE IF NOT EXISTS `test_table` (īut when I create increase the column length with a single character as below:ĬREATE TABLE IF NOT EXISTS `test_table2` ( I have created below table with two columns as "f1" varchar with the length of 32,765 and "f2" with 32766. It means including all columns it should be less than 65,535 bytes. But after Mysql version 5.0.3 varchar can store maximum of 65,535 characters.īut again this limit is having limitation of maximum row size which is 65535 bytes. The limit is enforced regardless of storage engine, even though the storage engine may be capable of supporting larger rows. Don't make the exception to be the rule - I know for auto-generated emails with 300 max characters.Maximum data what we can store in varchar in mysql was 255. The MySQL maximum row size limit of 65,535 bytes is demonstrated in the following InnoDB and MyISAM examples. ![]() See the syntax, examples, and rules for character sets and collations. The VARCHAR data type can have a maximum length of 65,535 characters, which is the same as the maximum row size.
