    I just started today a new project and I’m facing a problem with WooCommerce thumbnails: while single and catalogue images look perfect (all images are 960x960px), the thumbnails beside the main image on the single product page look blurry. I already used Regenerate Thumbnails with no results. Starting this new project, I uploaded all the images and installed WooCommerce before switching to GP Premium… inspecting the item in Chrome I found some reminiscences of the original WP theme in WooCommerce CSS… but frankly speaking I have no idea if this might be the cause…

    Hi there,

    Your URL is going to a 404. Can you double check?

    Thanks! 🙂


    Hi Tom,

    sorry for delay but I wanted to check if the issue was eventually related to image quality and compression. So I decided to start from scratch once again. So, fresh new install and now all the product images that have been upload are higher quality and less compressed…

    take a look at this address…


    All images are quite sharp and well defined, but if you go in a single product page, for example:


    you’ll see that the thumbnails are quite blurry… while the main image is sharp and well defined…

    Hi there, you may want to try regenerating your thumbnails with this plugin:



    Hi David, tried that already but with no results at all…

    OK, Woo’s latest update set the gallery thumbnail to a fixed 100px x 100px size. Which is being scaled up by the layout. You can use this filter to change that to a higher resolution.

    add_filter( 'woocommerce_get_image_size_gallery_thumbnail', function( $size ) {
        return array(
        'width' => 150,
        'height' => 150,
        'crop' => 0,
    } );

    Try increasing it using this method and then regenerate thumbnails.


    Thank you very much David, where should I place this piece of code without messing up the whole site (I’m not that confident in this kind of programming…).

    Here is an article on adding PHP, which includes a link to the Code Snippets plugin which is the simplest way to add these codes:
