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.
1. Selecting an Image. Original image size cannot exceed 1252Ã626 pixels (with a max file size of 5MB).

The header image is a horizontal bar, so any landscape-oriented photo will look better than a portrait (vertical) photo. Although you can resize the image, it doesn't appear to align 100% accurately.
