LinkedIn Carousel Dimensions (Exact Pixel Sizes)
LinkedIn carousels work at two dimensions: 1080x1350px for a 4:5 portrait layout, or 1080x1080px for a 1:1 square layout. Those are the two sizes CarouseLabs builds carousels at, and they cover the two aspect ratios LinkedIn's document post viewer supports well. Whichever one you pick applies to the entire carousel — LinkedIn doesn't allow mixing ratios within a single post, so every slide, usually 7 to 9 of them, has to share the same pixel dimensions. If you're building slides manually, getting this exact and consistent across every single one is tedious and easy to get slightly wrong. CarouseLabs sets the dimensions automatically the moment you choose your ratio, and every slide it generates comes out at that exact size, with margins and layout already accounted for.
How It Works
- 1
The two exact sizes
4:5 portrait is 1080x1350px. 1:1 square is 1080x1080px. Both are standard, high-resolution dimensions that display cleanly in LinkedIn's feed and document viewer without any downscaling artifacts or compression softness, whether someone's viewing on a phone or a desktop browser. There is no other size CarouseLabs outputs — every carousel is one of these two, chosen upfront.

Portrait (1080x1350px) fits more vertical content
The extra height gives text-heavy slides room to breathe, which is useful for step-by-step breakdowns, longer captions per slide, or quotes with attribution that need a second line. It's the closer of the two to a full-screen mobile read, and it tends to occupy more of the visible feed as someone scrolls past it, which can make a post harder to scroll past without stopping.
- 3
Square (1080x1080px) is more compact
Square trims the vertical space, which suits slides built around a single strong statement, an icon, or a simple diagram rather than paragraphs of text. It reads as tighter and more image-forward, and it can feel less demanding to swipe through when the content per slide is intentionally minimal, which some formats benefit from more than others.

CarouseLabs sets the pixel dimensions for you
You choose portrait or square once, at the start of generating a carousel, and CarouseLabs locks every slide to that exact pixel size automatically. There's no manual canvas setup, no resizing between slides, and no risk of one slide coming out a few pixels off from the rest the way it easily can when building slides by hand in a design tool, slide by slide.

Export at full resolution
Slides are generated ready to post directly to LinkedIn or download at full 1080px-wide resolution, so nothing looks soft or pixelated once it's live. Downloading and uploading as a PDF is what activates LinkedIn's native swipeable carousel viewer if you're not posting directly from CarouseLabs to the platform, and the exported file keeps the exact dimensions you generated at.
Who Uses This
Anyone who searched specifically for the pixel numbers because they're setting up a carousel manually and need exact values before opening a design file and starting from a blank canvas
Designers double-checking dimensions before building a carousel template in an external design tool from scratch, so nothing needs correcting after slides are already laid out
Developers or marketers documenting brand specs who need the precise LinkedIn carousel sizes written down and on record for a team to reference repeatedly across projects
Creators comparing 1080x1350px against 1080x1080px side by side to decide which fits an upcoming post's specific content before committing to either one
Teams standardizing carousel exports so every file matches LinkedIn's expected dimensions exactly before it ever gets uploaded, avoiding rejected, cropped, or misformatted posts going live
