I'm a little late to the party, but I just ran into this issue too. I ended up just creating a blog on how to do it, since I had some previous experience with CSS. Hopefully it'll be corrected in a future Squarespace update. https://codyturk.com/blog/how-to-change-squarespace-video-gallery-thumbnail-images-to-16x9 Edit: Sorry this blog post was removed awhile back. Big thanks for someone emailing me to bring it to my attention. Try this code. Class name might be different for some. // Video Thumbnails 16x9 .lessons.collection-content-wrapper .grid-image-wrapper { padding-bottom: 56.25%; }
