Portrait works for feeds, Story / Status for vertical sharing, Square for profiles, and Landscape for screens.

Room for real words
Use a short paragraph rather than squeezing everything into a decorative overlay.
Photo-safe composition
Editorial layouts keep text away from faces and important details.
Easy to send
Export a portrait card, phone wallpaper, or landscape image ready for messaging.
