note caution CAUTION Note that in AEM, crop aspect ratios are defined as height/width. This differs from the conventional definition of width/height and is done for legacy compatibility reasons. The content authors will not be aware of any difference as long as you provide a clear name of the ratio since the name is shown in the UI and not the ratio itself.
