I donât know if it has changed, but as for the Carousel ads, Facebook recommends 1800Ã1800 when i create a new ad. Hi Jon, I was previously able to replace the 470Ã246 thumbnail pulled from websites with an uploaded image on facebook.
2018 Update: Facebook Event Cover Photo Size. Checked and verified January 2, 2018: The recommended Facebook event cover photo size is 1200 x 628, same as a link share. This is a 1.91:1 ratio. I strongly recommend you use a larger photo! I checked the display size on iPhone, iPad and desktop, in both the Event and the linked Group.
