Default Aspect Ratio: Proportional relationship between its width and its height.
If you'd like to change the default aspect ratio for your Cover Images, click the edit pencil icon on a page cover and then click "Customize". In the next popup, click the "Aspect Ratio Options" and then the dropdown that appears will give you a few different view options.
To change the size of your Cover Images, you'll need to do one or two things:
1) Edit the number of columns within the Layout Options. You can access this from the Remote when in a Gallery. Fewer columns will result in larger images.
2) Change the size, margins of the "Website Container" from the floating Remote. This will change the overall size of the entire site, but it also affects cover images.
3) A combination of both! It's definitely useful to experiment. We recommend previewing your site when you've made changes so you can see how it will look when it's live.
