How to Size SNS Carousel Slides
Carousel (multi-image) posts are swiped through slide by slide, so every slide needs the same size and aspect ratio. Most platforms — Instagram, Facebook, LinkedIn, and X — support a 1080px-wide base at either square (1:1) or vertical (4:5) ratio. Square slides display consistently on both desktop and mobile, while vertical slides take up more mobile screen space and grab more attention.
To design multiple slides so they flow together like one big image, create a canvas as wide as one slide's width multiplied by the number of slides, design across the whole thing, then slice it evenly and export each section as a slide. For five 1080px slides, for example, you'd work on a 5400×1080px canvas.
Feed thumbnails and profile grids can crop the edges of an image, so keep important text or logos about 8% away from the edges (the safe zone) to avoid losing key content.
