Where can i edit admin thumb size?

Question

I already lost many hours without success. Does anyone know where we can increase admin products thumb grid? By default it generates a cached picture with 75px but limited to 55px in grid.

Many thanks.

Open vendor/magento/theme-adminhtml-backend/etc/view.xml and change width and height

<media>
    <images module="Magento_Catalog">
        <image id="product_listing_thumbnail" type="thumbnail">
            <width>75</width>
            <height>75</height>
        </image>
    </images>
</media>

Also you need to change width of following css class:

.data-grid .data-grid-thumbnail-cell

.data-grid .data-grid-thumbnail-cell img

NB: Don't modify core file
