Google sent out an email to Google Merchant Center advertisers and users that the minimum size for product images is going up to 500 x 500 pixels starting on January 31, 2027. Google recommends at least 1500x1500 pixels or above, but the minimum size requirement is 500x500, which, in my opinion, is way too small.
Google also updated the help documentation with a big notice that reads:
We recently announced new image size requirements of at least 500 x 500 pixels for all products beginning January 31, 2027. However, to ensure best performance in all listing formats, we recommend that you provide images 1500x1500 pixels or above.
Here is a screenshot of the top of that page:
If you have images smaller than 500 × 500 pixels, you will see the warning "Image too small" or "Image too small due to upcoming policy changes" in your Merchant Center account.

Update: Well, tiny one:
Small update here for Google Merchant Center, Google labeled this box as "important" because making it red was not enough - older story on this update at https://t.co/qTS575b2vT pic.twitter.com/woz0kuBhwe
