Post listings of stories and articles in feeds are determined based on placement of images and text in your story and are created automatically. Currently, Medium does not provide a preview tool for visualizing post listings before publication because they will appear differently on desktop, mobile web and in our apps. (Each platform renders post listings differently.)
At this time, the best practice for post listings to reliably include both an image (wide horizontal rectange format) and story title, and at least partial subtitle are:
- Upload an image as the first item in your story, following our preferred image sizes.
- Click on that image (on desktop) to select it. Press Shift + F on your keyboard to set it as featured image.
- Press Alt / Opt and click to set a focal point in the image, which will guide any automatic cropping that may occur.
- Begin your story's title and subtitle.
