Every slide uses the same size
For a continuous image, all exported slides must use one ratio and one height. This version supports square 1080 × 1080 and portrait 1080 × 1350 slides. Additional publishing ratios require channel-specific testing.
Calculate your continuous canvas
Multiply the width of one slide by your slide count. Five portrait slides require a 5400 × 1350 canvas. The height stays constant: only the width grows.
Check the seams before publishing
Use the swipe preview and inspect subjects near each cut. Add the images to a single post in slide_01, slide_02 order. Avoid individual crops or filters that would break the shared image. Instagram’s help page describes up to 20 items; third-party publishers may differ.
