Please note that our Legacy Themes have been replaced by new Thrive Theme Builder Themes. While our Legacy Themes are still functional, we are no longer actively developing them. This article explains why the Thrive Theme Builder themes don't need fixed "Featured Image" sizes.
Storied is a theme optimized for blogging and it looks fantastic with the use of images and other media. It can also be customized to a simple, minimalist site for text-only content.
Recommended Image Sizes
Here are the recommended image sizes for use in the Storied theme:
Wide, full width featured image: 1270px
Wide featured image with sidebar or narrow layout: 978px
Thumbnail featured image: 320px
Page section background image: 1270px
Site background image: 1920px
Author image (author widget, custom image): 120px
Author background image: 700px
Blog masonry or grid layout: 320px
On a style like you see on the demo site, the recommended image width for (almost) all featured images is 978px.
