How to make seamless Instagram carousel mockups that swipe as one story

The panoramic-split technique that makes device mockups flow across all 10 Instagram slides with matching backgrounds.

Instagram carousels get 1.4× the reach of single-image posts. Seamless carousels — where the background flows across every slide — outperform basic ones by another 20–30%.

The panoramic-split workflow

  1. Design one wide canvas at 10800×1350 (10 slides × 1080 wide, portrait height).
  2. Place your device mockups and text across the full width. Let backgrounds bleed across slide boundaries.
  3. Split into 10 individual 1080×1350 images.
  4. Upload in order — Instagram stitches them into a swipe story.

Why device mockups work here

A phone moving across four slides — screen changing each time — reads like a sequence, not a slideshow. That's the whole trick.
