What is the maximum size for a Textpattern article?
Is there a limit on comment size?


Textpattern uses a MySQL mediumtext field for article bodies. This limits the maximum size to about 16 megabytes per article—including any HTML tags that form part of the article body, but not counting images or files, since these are stored separately.

You’re more likely to run into a PHP memory limit than reach the article storage limit. Some hosts set the PHP memory limit to 8 megabytes.

The limit on comment size is 64 kilobytes.
