Instagram Reels
Buffer 2026 Instagram size guideFormat
Export the Reel itself as vertical 9:16 at 1080 x 1920, but treat the cover as its own asset because profile grid previews crop to 3:4. Keep the face, title, and product in the center-safe area.
Captions
Use readable burned-in captions for feed viewers, but keep them away from the lower UI and do not let large caption blocks ruin the cover frame.
Thumbnail / cover
Highest priority. Design the cover like a still photo: clear face/product, one short title, and a grid-safe crop. A random speaking frame usually looks worse on the profile grid.
Title / copy
Caption text and hashtags still matter, but the first visual impression on profile visits is the cover image.
