LinkedIn carousel size: the complete guide

Written by Sakib, LinkedIn Carousel Maker · Updated 2026-10-20

The best LinkedIn carousel size is 1080 × 1350 pixels (4:5 portrait). 1080 × 1080 (1:1) also works. Export as a PDF; LinkedIn accepts documents up to 100 MB and 300 pages as of October 2026.

Should you use 4:5 portrait or 1:1 square?

A LinkedIn carousel is a PDF uploaded as a document post. LinkedIn shows it one page at a time and readers swipe or tap through it, so the “size” of a carousel is really the shape and resolution of its pages. Get that right and your slides fill the screen; get it wrong and they shrink into a letterbox with empty bands around them.

Portrait 4:5 is the default for a reason. Most LinkedIn reading happens on phones, and a portrait page takes up more of the feed than a square one at the same width. That extra height is room for a bigger hook and more breathing space around each point. Choose square when your content is very short per slide, or when you want the carousel to match square images you already post. Avoid landscape pages: they appear small in the mobile feed and the text quickly becomes hard to read.

Both sizes share a width of 1080 pixels, so you can switch between them in the editor without losing your words. Layouts reflow to the new height.

Where should you keep text on a slide?

LinkedIn shows the whole page, but text that runs to the very edge looks cramped and is easy to miss next to LinkedIn's own page controls. Our layouts keep a 72 px margin on every side of the slide and reserve the bottom 120 px for the author line, the slide counter and the swipe hint. On a portrait slide that leaves a safe area of 936 × 1158 px.

• Keep headlines inside the margin and short enough to read at a glance on a phone.
• Put recurring details (name, handle, page number) in the same spot on every slide.
• Leave the first slide uncluttered: it doubles as the thumbnail people see before they tap.

What PDF page size and resolution should you export?

When you export, each slide becomes one PDF page with exactly the slide's proportions, 1080 × 1350 for portrait or 1080 × 1080 for square, so LinkedIn has nothing to pad or crop. Slides are rendered at 2× their pixel size (2160 × 2700 for portrait) and compressed, which keeps small text crisp on high-density screens while the file stays light enough to upload quickly.

The PNG export uses the same 2× rendering and gives you one image per slide in a ZIP, which is handy for other channels. For LinkedIn itself, upload the PDF: individual images post as a gallery, not as a swipeable document.

How many slides and how large a file can you upload?

LinkedIn accepts documents up to 100 MB and 300 pages (as of October 2026), so file size is rarely the problem. Attention is. A carousel in this editor holds up to 20 slides: one hook, one idea per slide and a closing call to action usually needs far fewer.
