What size should a LinkedIn infographic be?
A LinkedIn infographic for a single feed image should be built at 1200×1500px (4:5 portrait), the tallest ratio the feed displays without cropping. If the infographic has more content than a single portrait frame can hold legibly, split it across a carousel at 1080×1350px per slide instead of shrinking everything to fit one image.
Infographics are the image type most likely to fail from being sized wrong, because they usually pack in more text, data points, and visual hierarchy than a quote card or a photo does. At 1200×1500px, small text and detailed charts are still legible on a phone screen if the layout keeps a clear hierarchy — a headline, a small number of clearly separated sections, and enough white space that nothing feels cramped. Push much more content into that same single frame and text sizes drop to the point where they're unreadable at typical mobile viewing size, no matter how correct the pixel dimensions are.
This is the actual decision point for infographic sizing: it's not really about finding a bigger canvas, since LinkedIn's feed won't display a meaningfully larger single image than 1200×1500px in a useful way, but about whether the content fits at readable text sizes within that frame at all. When it doesn't, splitting the same information across a carousel — each slide at 1080×1350px, covering one section of the infographic per slide — solves the problem properly instead of fighting it. This also plays to LinkedIn's format strengths, since carousels tend to hold attention longer than a single dense image because the swipe interaction itself demands active engagement.
A good rule of thumb: if an infographic needs more than roughly 4-5 distinct data points or sections to make its point, it's very likely a carousel candidate rather than a single-image candidate, regardless of how technically correct its dimensions are.
Key Points
- 1200×1500px (4:5 portrait) is the ideal single-image infographic size for LinkedIn's feed
- Legibility at mobile viewing size matters more than fitting everything into one frame
- Infographics with more than roughly 4-5 sections usually work better as a carousel
- Carousel slides for split infographic content should use 1080×1350px per slide
Example
A supply-chain consultant tries to cram a 7-step process into one 1200×1500px infographic and the text becomes unreadable on mobile; splitting the same 7 steps across a 7-slide carousel at 1080×1350px each keeps every step legible and the post ends up with a noticeably higher completion rate through the swipes.
Related Questions
Should a LinkedIn infographic be one image or a carousel?
It depends on content density. A simple infographic with a few clear sections works as one image; anything with several distinct data points or steps usually reads better split across a carousel.
What's the minimum text size for a readable LinkedIn infographic?
There's no universal number since it depends on the design, but as a practical check, view your export at actual phone screen size before posting — if body text is straining to read there, it's too small or the frame has too much content.
