What size should an Instagram carousel be?

Square (1080x1080) or portrait (1080x1350) both work well, and portrait fills more of the feed. Use one size for every slide so the swipe stays aligned.

What size is a LinkedIn carousel or document post?

A portrait ratio works best - a 4:5 shape such as 1080x1350 reads well as a page. Keep every page the same size so the set feels like one document.

Can I use a custom carousel size?

Yes. Set any width and height you like in Emaki Studio - just keep every slide identical so the swipe lines up and the set looks consistent.

Carousel size guide: the best dimensions to use

The right carousel size keeps every slide sharp and the swipe lined up, whatever you are posting - an Instagram set, a LinkedIn document post, or a TikTok photo carousel. The trick is to pick one size, use it for every slide, and design inside safe margins. Here is how to choose it and set it up in Emaki Studio.

1. Start from where it will be posted Instagram carousels are square (1080x1080) or portrait (1080x1350); LinkedIn document posts and TikTok photo carousels favour portrait. Pick the shape that fills the most feed space where you are posting.
2. Use one size for the whole set Every slide should be the same size so the swipe stays aligned and nothing jumps. A 4:5 portrait generally takes up the most room in a feed, which makes it a safe default.
3. Set the size in the editor On the setup screen choose a square or portrait preset (or type a custom size) and your slide count. Every frame is created at that exact size, so they line up cleanly.
4. Design inside safe margins Keep text and key elements away from the edges so nothing is clipped by rounded corners or the platform interface. Snapping and alignment guides help you place things the same way slide to slide.
5. Export at full resolution Export each slide at the size you set (1080px on the long edge is plenty), so it uploads sharp instead of being over-compressed by the app. Everything renders locally in your browser.
