# Change number of related products output

Add code to your child theme’s functions.php file or via a plugin that allows custom functions to be added, such as the [Code snippets](https://wordpress.org/plugins/code-snippets/) plugin. Avoid adding custom code directly to your parent theme’s `functions.php` file as this will be wiped entirely when you update the theme.

Please note that it does not work for all themes because of the way they’re coded.
