How to Enable or Disable Shipping Based on Product Dimensions in WooCommerce?

Managing shipping options effectively in WooCommerce is crucial, especially when dealing with products of varying sizes and weights. Some products might be too large to ship via standard methods, while others may qualify for special delivery options. The ability to enable or disable shipping based on product dimensions can help you control costs and improve customer satisfaction.

Why Control Shipping Based on Product Dimensions?

Enabling or disabling shipping based on product dimensions can be beneficial for several reasons:

• Cost Management: Prevent shipping charges that are too high for oversized items.
• Delivery Feasibility: Avoid offering shipping methods that are not possible for large or irregularly shaped products.
• Customer Experience: Ensure buyers receive accurate shipping options with no surprises at checkout.

By implementing this feature, you can customize the shipping process and ensure compliance with carrier restrictions.

How to Enable or Disable Shipping Based on Product Dimensions in WooCommerce

There are multiple ways to achieve this in WooCommerce. Let’s explore the most practical methods.

1. Using a Shipping Plugin

The easiest way to manage shipping based on product dimensions is by using a dedicated plugin. Some popular plugins that allow this functionality include:

• Table Rate Shipping for WooCommerce
• Advanced WooCommerce Shipping
• Flexible Shipping for WooCommerce

These plugins let you create rules based on height, width, and depth. Simply:

1. Install and activate the plugin.
2. Navigate to the Shipping Settings.
3. Create custom rules where specific dimensions enable or disable certain shipping methods.
4. Save changes and test the functionality.

This method is user-friendly and does not require coding knowledge.

2. Custom Code Snippet via Functions.php

If you prefer a manual approach, adding a custom snippet in your functions.php file allows you to enable or disable shipping methods based on product dimensions.

Here’s how you can do it:

function disable_shipping_based_on_dimensions($rates, $package) {
    foreach ( $package['contents'] as $item ) {
        $product = wc_get_product( $item['product_id'] );
        $width = $product->get_width();
        $height = $product->get_height();
        $length = $product->get_length();

        if ( $width > 50 || $height > 50 || $length > 100 ) { 
            unset( $rates['flat_rate'] ); 
            unset( $rates['free_shipping'] );
        }
    }
    return $rates;
}
add_filter( 'woocommerce_package_rates', 'disable_shipping_based_on_dimensions', 10, 2 );

In this example:

• Products exceeding 50cm in width or height, or 100cm in length, will have Flat Rate and Free Shipping disabled.
• This snippet ensures that oversized items do not qualify for certain shipping methods.

Always test the changes thoroughly and create a backup before modifying the code.

3. Configuring WooCommerce Shipping Classes

An alternative method involves using Shipping Classes to manage shipping exclusions based on product dimensions.

Follow these steps:

1. Go to WooCommerce > Settings > Shipping.
2. Select Shipping Classes and create a new class like Oversized Items.
3. Edit the product and assign this Oversized Items class to products exceeding your desired dimensions.
4. Next, go to Shipping Zones, and under a chosen shipping method, ensure that the Ovesized Items class disqualifies certain options.

This method is effective and does not require additional plugins or coding.

Testing Your Shipping Rules

Before going live with any changes, always test the shipping rules:

• Try different products: Ensure the correct options appear based on dimensions.
• Use a staging site: Prevent disruptions to live sales.
• Check multiple shipping zones: Certain exclusions might not apply globally.

Final Thoughts

Whether you use a plugin, custom code, or WooCommerce’s built-in shipping classes, enabling or disabling shipping based on product dimensions can significantly enhance the efficiency of your store.

By implementing smart shipping rules, you can save on unnecessary costs, meet logistical constraints, and simplify product handling for your customers.
