You can share a square (1:1), vertical (9:16), landscape (16:9) or Instagram-oriented (4:5) post with Ripl. You can select your post size by tapping the three dots above your keyboard, then selecting the post size above the keyboard on the right side. We recommend using vertical posts for Instagram Stories and Facebook Stories, landscape posts for Facebook Cover Videos, YouTube and LinkedIn, and square for sharing across more than one platform. The 4:5 format (the far right in the screenshot) is a special aspect ratio developed for the updated Instagram Feed experience and goes best for Instagram Feed.
