Want to show extra info on your WooCommerce product pages — like Refund Policies, or Product Videos? The best way to do that is by adding a custom tab.

In this tutorial, you’ll learn how to add a custom tab to WooCommerce product pages using code — no plugins required!

Why Add a Custom Tab?

WooCommerce comes with default tabs like Description, Reviews, and Additional Information. But sometimes you need more flexibility, for example:

• Display a Refund & Return Policy
• Share Shipping Info
• Embed a Product Demo Video

Let’s get started!

Add Custom Tab Using WooCommerce Filter

Use the woocommerce_product_tabs filter to insert your own tab:

add_filter( 'woocommerce_product_tabs', 'custom_product_tab' );

function custom_product_tab( $tabs ) {
    $tabs['extra_tab'] = array(
        'title'    => __( 'Size Guide', 'your-textdomain' ),
        'priority' => 50,
        'callback' => 'custom_product_tab_content'
    );
    return $tabs;
}

function custom_product_tab_content() {
    echo '<h2>' . __( 'Size Guide', 'your-textdomain' ) . '</h2>';
    echo '<p>This is the Size guide details for this product. You can insert images, tables, or any HTML here.</p>';
}

This code adds a new tab called Size Guide after the default tabs.

Make the Tab Conditional

Want to show the tab only for specific categories or products? No problem!

Example: Show Only for Products in “Clothing” Category

function custom_product_tab( $tabs ) {
    global $product;

    if ( has_term( 'clothing', 'product_cat', $product->get_id() ) ) {
        $tabs['extra_tab'] = array(
            'title'    => __( 'Size Guide', 'your-textdomain' ),
            'priority' => 50,
            'callback' => 'custom_product_tab_content'
        );
    }

    return $tabs;
}
add_filter( 'woocommerce_product_tabs', 'custom_product_tab' );

Need More Flexibility?

you can make the tab content dynamic by fetching custom fields or meta data.

Load from a Custom Field

function custom_product_tab_content() {
    global $post;
    $value = get_post_meta( $post->ID, '_your_meta_key', true );
    echo wp_kses_post( $value );
}

Final Thoughts

Adding a custom tab to WooCommerce product pages is a powerful way to provide helpful info to your customers. Whether it’s size guides, policies, or videos — it improves user experience and can boost conversions.
