How to Display Attachment File Size in WooCommerce

The WooCommerce Product Attachment Pro plugin lets you show the file size of attachments on the frontend. This helps customers understand how large a file is before downloading it, which improves transparency and user experience.

You can easily enable or disable this option using a simple Yes / No setting.

Why Show Attachment Size?

Displaying the attachment size helps to:

• Set clear expectations before downloading
• Improve trust and transparency
• Help users with limited bandwidth
• Reduce unnecessary download attempts

Steps to Display Attachment Size

Enable Attachment Size Display

1. Go to Product Attachment → Settings

   Locate the option Show Attachment Size

   Select Yes to display the file size

   • Select No to hide the file size
2. Click Save Changes

Once enabled, the attachment size will appear next to the attachment name on the frontend.

Frontend Display

• When enabled, customers will see the file size (for example: PDF – 2.4 MB)
• When disabled, only the attachment name or link will be shown
• This applies to both file uploads and downloadable attachments

Important Notes

• File size is displayed only for uploaded files
• External URLs do not show file size
• The setting applies globally to all attachments
• Styling follows your theme but can be customized using CSS

Conclusion

Showing attachment file size is a small but useful feature that improves clarity for customers. With a simple Yes or No option, you can decide whether to display file size across your WooCommerce store and create a better download experience.
