Smart and Ghost optimize your images out of the box, so there's not much you need to worry about 🤷
For best results, follow these two rules:
- Homepage hero images should be in a 1:1 aspect ratio (square). 2000 by 2000 px is a great place to start, but sizing is flexible.
- All feature images should be in an HD aspect ratio (16 / 9). 2000 by 1125 px is, again, a great place to start, but sizing is flexible.
For images in a post, upload whatever you like–Ghost will optimize it for you!
