# How to Change Thumbnail Product Image Size in WooCommerce Emails
WooCommerce emails are crucial for customer engagement and order management. A key aspect of these emails is the product image thumbnail. If your thumbnails are too large or too small, it can negatively impact the email’s appearance and user experience. This article will guide you through how to efficiently change the size of product image thumbnails in your WooCommerce emails, ensuring they are optimized for readability and visual appeal.
Understanding the Issue: Why Change Thumbnail Sizes?
Poorly sized thumbnails can lead to several problems:
- Cluttered Emails: Large thumbnails can make your emails look bulky and unprofessional, leading to lower engagement.
- Slow Loading Times: Large images increase email loading time, frustrating recipients on slower connections.
- Poor Mobile Experience: Large thumbnails can look distorted or require excessive scrolling on mobile devices.
- Inconsistent Branding: Images that are too small might appear blurry and unprofessional, damaging your brand image.
- Ease of Use: Usually involves simple settings adjustments within the plugin’s dashboard.
- No Coding Required: Perfect for users without coding experience.
- Additional Features: Often includes other email customization options beyond image size.
- Plugin Dependency: Requires installing and maintaining an additional plugin.
- Cost: Some plugins are premium and require a purchase.
Therefore, controlling the size of your product image thumbnails is essential for a polished and professional email experience.
Methods to Change WooCommerce Email Thumbnail Size
There are several ways to adjust the size of product thumbnails in WooCommerce emails. The best method depends on your technical comfort level and the specifics of your WooCommerce setup.
Method 1: Using a WooCommerce Email Plugin (Recommended)
The easiest and most reliable method is to use a dedicated WooCommerce email plugin. Many plugins offer granular control over email design and settings, including image sizes. These plugins often provide a user-friendly interface, eliminating the need for code editing.

Method 2: Customizing the `woocommerce_email_order_items_table` Function (Advanced)
This method involves directly modifying WooCommerce’s core functionality through a child theme or a custom plugin. It offers more precise control but requires coding skills. Proceed with caution, always backing up your files before making any code changes.
To change the thumbnail size, you’ll need to modify the `woocommerce_email_order_items_table` function. Here’s an example of how you might modify it:
add_filter( 'woocommerce_email_order_items_args', 'custom_order_item_thumbnail_size' );
function custom_order_item_thumbnail_size( $args ) {
$args['size'] = 'thumbnail'; // Change 'thumbnail' to your desired size. Example: 'shop_thumbnail' or array(100,100)
return $args;
}
Replace `’thumbnail’` with your desired image size. You can use predefined sizes (e.g., `’shop_thumbnail’`, `’medium’`, `’large’`) or specify custom dimensions as an array (e.g., `array(100, 100)` for a 100×100 pixel image). Remember to register your desired image sizes in your theme’s `functions.php` file if you are using custom dimensions.
Advantages:
- Precise Control: Allows for highly specific adjustments to thumbnail size.
Disadvantages:
- Requires Coding Skills: Modifying core functions requires coding expertise.
- Risk of Conflicts: Incorrect modifications can break your website’s functionality.
- Lost on Updates: Changes might be overwritten during WooCommerce updates.
Method 3: Using CSS (Intermediate)
You can attempt to control the image size using CSS, but this approach is less reliable and might not work consistently across all email clients.
This method involves adding custom CSS to your WooCommerce emails using a plugin or your theme’s custom CSS area. You would target the image element within the email template. However, due to the variability in email client rendering, this method isn’t guaranteed to work consistently.
Conclusion: Choosing the Right Method
The best method for changing WooCommerce email thumbnail sizes depends on your technical skills and comfort level. For most users, a WooCommerce email plugin offers the easiest and most reliable solution. If you’re comfortable with coding and require precise control, modifying the `woocommerce_email_order_items_table` function is a viable option, but remember to back up your files and proceed cautiously. Avoid relying solely on CSS for this purpose due to its inconsistency across various email clients. By implementing one of these methods, you can significantly improve the visual appeal and user experience of your WooCommerce order emails. Remember to always test your changes thoroughly after implementation to ensure everything works as expected.
