Exact carousel dimensions for LinkedIn, Instagram, TikTok and Facebook: pixel sizes, aspect ratios, formats, slide counts and safe zones. Free reference.

LinkedIn carousels are document posts. You upload a PDF, not images, and LinkedIn renders each page as a slide.
The first slide sets the aspect ratio for the whole carousel. Mixed ratios get cropped to match slide one.
Photo mode fills the screen, so anything outside the centre 80% risks sitting under the caption and action rail.
Carousel cards crop to square in most placements, so keep text away from the edges.
LinkedIn and Instagram both recommend 1080 × 1350 at 4:5, so a single portrait design covers the two platforms where carousels perform best. Design once at 4:5, export a PDF for LinkedIn and images for Instagram, and add a 9:16 crop only if you also post to TikTok.
Design at 1080 × 1350 pixels, a 4:5 portrait ratio, and export as a PDF. LinkedIn carousels are document posts, so the upload is a single PDF file where each page becomes a slide.
LinkedIn carousels use the document post format, which was built for slide decks and reports. LinkedIn renders each PDF page as one swipeable slide, which is why an image upload creates a multi-image post rather than a carousel.
Design at 1080 × 1350 pixels, a 4:5 portrait ratio, and upload JPG or PNG images. Instagram supports up to 20 slides, and the first slide sets the aspect ratio for every slide after it.
Yes. Both platforms recommend 1080 × 1350 at 4:5, so one portrait design covers both. You only need to export twice: a PDF for LinkedIn and images for Instagram.
Between 6 and 10 works best on both LinkedIn and Instagram. Enough to develop an idea, few enough that people reach the end, which is what drives the completion signal both feeds reward.
Every size guide gives you numbers. What they cannot tell you is whether a design still reads once it is cropped to them, because none of them ships designs. We ship 33 layout families, so we render each one at every aspect the product supports and check whether the text clips. That is 165 renders, measured rather than assumed.
| Crop | Families that reflow cleanly |
|---|---|
| Feed portrait (4:5) | 33 of 33 |
| Feed square (1:1) | 31 of 33 |
| Story and Reel (9:16) | 33 of 33 |
| Pin (2:3) | 33 of 33 |
| Landscape (16:9) | 16 of 33 |
Landscape is where it hurts, and that is the honest answer to “can I reuse this at 16:9”: these layouts are tuned for a tall frame, so a wide crop is where a headline runs out of room. 3 families have not been through the audit yet (case-study, editorial-carousel, tutorial-steps), so treat those as untested rather than passing. The full table is on the templates hub.
