Frequently Asked Questions

What is the default WooCommerce thumbnail size?
The default WooCommerce thumbnail size is 300x300 pixels. This is used in the shopping cart, sidebar widgets, and related product sections. You can change this in WooCommerce > Settings > Products.
Can I change WooCommerce thumbnail dimensions?
Yes, go to Appearance > Customize > WooCommerce > Product Images to adjust thumbnail sizes. After changing, use the Regenerate Thumbnails plugin to update all existing product images.
Why are my WooCommerce thumbnails blurry?
Blurry thumbnails usually mean the original uploaded image was too small. WooCommerce can shrink images but cannot improve quality when scaling up. Always upload images larger than your thumbnail size.
Should I manually create WooCommerce thumbnails?
Usually no — WooCommerce auto-generates thumbnails from your main product image. However, if you want different cropping or a different composition for thumbnails, you can manually upload a custom thumbnail.
