What are the Maximum Storage Capacities of MySQL's TEXT Data Types?

MySQL TEXT Data Type Maximum Storage Capacity

MySQL provides four TEXT data types with varying storage capacities: TINYTEXT, TEXT, MEDIUMTEXT, and LONGTEXT. Determining the appropriate type for your specific needs is crucial to optimize database performance and avoid storage limitations.

Let's delve into the maximum storage size for each TEXT data type assuming a UTF-8 character encoding:

TINYTEXT

TINYTEXT is the smallest TEXT data type with a maximum storage capacity of 255 bytes. This translates to 255 characters or approximately 255 single-byte UTF-8 characters.

TEXT

TEXT has a significantly larger storage capacity than TINYTEXT and can hold up to 65,535 bytes. This corresponds to approximately 64 kilobytes of data or 64,535 UTF-8 characters.

MEDIUMTEXT

MEDIUMTEXT is designed for larger text content and supports a maximum storage capacity of 16,777,215 bytes. This equates to 16 megabytes of data or approximately 16,777,215 UTF-8 characters.

LONGTEXT

LONGTEXT is the most spacious TEXT data type and can store up to 4,294,967,295 bytes. This massive storage capability translates to 4 gigabytes of data or 4,294,967,295 UTF-8 characters.

It's important to note that the maximum number of characters that can be stored in a given TEXT column ultimately depends on the specific character encoding used.
