How To Increase Default Number of Fields in Custom Fields Dropdown

Snippets by IsItWP

Are you looking for a way to increase the default number of fields in the custom fields dropdown? While there’s probably a plugin for this, we have created a quick code snippet that you can use to increase the default number of fields in the custom fields dropdown from the default of 30 to 60.


All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

Keep in mind the same dropdown is displayed for each custom field metabox you have, so you may want to set the limit to a reasonable number if you decide to change line 3.

add_filter( 'postmeta_form_limit' , 'set_customfield_limit' );
function set_customfield_limit( $limit ) {
    $limit = 60;
    return $limit;
