What are the Storage Limits of MySQL's TINYTEXT, TEXT, MEDIUMTEXT, and LONGTEXT Data Types?

Optimizing Text Storage: Understanding the Storage Limits of TINYTEXT, TEXT, MEDIUMTEXT, and LONGTEXT

MySQL provides four data types tailored for storing text data: TINYTEXT, TEXT, MEDIUMTEXT, and LONGTEXT. Each type varies in its maximum storage capacity. Let's delve into their respective storage limits.

TINYTEXT: Compact Storage for Short Text

TINYTEXT caters to columns storing small amounts of text, allowing a maximum length of 255 bytes. This equates to 255 characters if using UTF-8 character encoding. TINYTEXT is ideal for storing short descriptions, titles, or any text that fits within this modest limit.

TEXT: Standard Solution for Moderate-Length Text

TEXT provides a more generous storage capacity, accommodating up to 65,535 bytes (64 KiB). Under UTF-8 encoding, this translates to 65,535 characters. TEXT is a suitable option for columns containing moderate-sized text, such as biographies, product descriptions, or short articles.

MEDIUMTEXT: Ample Storage for Medium-Sized Text

MEDIUMTEXT significantly increases the storage potential, offering a maximum of 16,777,215 bytes (16 MiB) or 16,777,215 characters in UTF-8. This data type is designed for storing medium-sized text, including blog posts, customer reviews, or forum discussions.

LONGTEXT: Unrestricted Storage for Extensive Text

LONGTEXT reigns supreme for storing vast amounts of text, providing a maximum storage capacity of 4,294,967,295 bytes (4 GiB). With UTF-8 encoding, this translates to an astounding 4,294,967,295 characters. LONGTEXT is the ultimate choice for storing large text documents, research papers, or any text content that requires an expansive storage capacity.

It's important to note that the actual storage requirements in bytes vary based on the character encoding used. UTF-8, being a variable-length encoding, consumes more bytes for certain characters than fixed-length encodings like ASCII.
