Etsy moderator Cheyne published the following announcement on the Etsy discussion board, explaining changes to the seller listing page:
Starting today, some of you will begin noticing a few visual adjustments to your listing pages. This is a continuation of work we began before the holidays.
These adjustments primarily aim to improve accessibility for visually impaired visitors. The information on your listings will now fill more of the page. Images are larger than before and your content will take up more space, allowing your items to be the true focus of the page. Listing pages will contain the same information as before.
When we began testing changes to the listing page before the holidays, we heard a lot of feedback and questions from you about the layout and focus on images. We are not currently changing the recommendation for image sizes and you aren’t required to update your photos. Since your listing images are presented differently based on the many different screen sizes that buyers use to visit Etsy, there is no one perfect size for an image on Etsy.
- If you see that your photos are blurry, check the sizes you have uploaded. In the listing process, we encourage you to upload images 1000px in either dimension but you are welcome to upload an even larger image.
- You may see bars on either side of an image with a portrait aspect ratio (the image is taller than it is wide). This allows the page to display the entire photo without stretching or cropping. We don’t recommend cropping or changing these images to optimize for the listing page layout.
We’ll closely monitor the effects of these changes and update you when this work is complete.
