Question

Does anybody have a solid reference source on ad sizes? I ask because it seems that right now Facebook ad manager preview and what actually displays on feeds is not accurate  

Answer 1

Facebook changes around their recommendations like every year for a long time it was the standard 1200x628 but recently they pushed to keep everything square

That's what I am noticing too, I appreciate you confirming it because I was wondering if I am losing my mind over here. All of my previews show landscape, "crop to square" is absolutely unchecked, and yet every time the ad comes across my personal feed on ANY platform, it is cropped to square -_-. Guess the answer is probably just design for square. lol
