When using WooCommerce and a product has many variations, you may want to increase the number of variations that show in the backend of the site on one pagination page for editing. This can make it easier to edit multiple variations without constantly having to choose the next page of variations.

It can be even more useful for when you are reordering a long list of variations manually.

Place the following code anywhere in your child theme’s functions.php document. The following will show 50 variations per pagination page for editing. You can change the number on line three to any amount you want to see per pagination page.

Be careful though, increasing the amount to something super high like 1000 could crash WordPress or the browser.

// increase variation per pagination page
function increase_variations_per_page() {
	return 50;
}
add_filter( 'woocommerce_admin_meta_boxes_variations_per_page', 'increase_variations_per_page' );
