Limit post titles with a character limit within the WordPress dashboard. The plugin works with default post types (posts/pages) as well as any custom post types defined by plugins or themes.
Simply set the character limit in the plugin’s settings pane and check which post types you wish to limit.
The title is limited within the dashboard only and pre-existing titles may need to be updated to match the new limit.
