The two best image sizes for a LinkedIn post are 1080 x 1080 pixels (square) or 1080 x 1350 pixels (portrait). For link previews, use 1200 x 627 pixels. Your profile photo should be 400 x 400 pixels.
That's the quick answer. The complete answer - every post type, profile element, company page graphic, and ad format - is in the cheat sheet below. Bookmark this page: we keep it updated as LinkedIn changes its specs.

Feed post images: the three formats that matter
Your feed content is where image size has the biggest impact on engagement, so let's start there.
Square posts (1080 x 1080, 1:1) are the reliable default. They display consistently on desktop and mobile without cropping, and they occupy a solid block of the mobile feed. Use them for quotes, announcements, product showcases, and anything you'll also repost to other platforms.
Portrait posts (1080 x 1350, 4:5) are the mobile-first power play. Over half of LinkedIn browsing happens on phones, and a 4:5 image fills significantly more vertical screen space than a square - pushing competing content out of view while someone considers yours. Use portrait for infographics, step-by-step visuals, and before-and-after reveals.
Landscape posts (1200 x 627, 1.91:1) match LinkedIn's link preview format. Whenever you share a URL, this is the size LinkedIn wants for the preview image - get it wrong and the platform crops it for you, usually badly. If your shared links pull in the wrong image or no image at all, the fix is in your page's Open Graph tags - our guide to Open Graph previews walks through it.
Carousel and document posts
Carousels are LinkedIn's highest-dwell-time organic format - people stop and swipe. Keep every card 1080 x 1080 for a smooth, consistent swipe experience. Mixing sizes mid-carousel causes visible jumps between cards.
Uploading a PDF as a document post? Use a 4:5 cover (1200 x 1500) so the first page displays fully in the feed.
Profile images: your digital handshake
Profile photo: 400 x 400 pixels. LinkedIn displays it as a circle, so center your face and keep important detail away from the corners. Upload high resolution - the photo appears everywhere from search results to comment threads at various sizes, and a blurry headshot at any of them undermines trust.
Background banner: 1584 x 396 pixels. The most under-used space on LinkedIn. Don't leave it as the default blue - use it for your value proposition, a key achievement, or your company branding. One design warning: your profile photo overlaps the banner's bottom-left area (bottom-center on mobile), so keep text and logos out of that zone.
Company page images
Logo: 300 x 300 pixels. A clean PNG with a transparent background works best - your logo appears in search results, on employee profiles, and beside every company update, often at small sizes. Simple and high-contrast wins.
Company banner: 1128 x 191 pixels. This is a wide, short strip - much shorter than the personal banner - so design for it specifically rather than reusing a personal banner. Your logo occupies part of the left side; keep focal points right of center.
Life tab: if you use LinkedIn's Life tab for recruiting, the main hero image is 1128 x 376 and the smaller custom module images are 502 x 282.
Ad specs: where wrong sizes cost money
Organic posts with wrong sizes look bad. Ads with wrong sizes get rejected or silently underperform while spending your budget.
Single image ads: 1200 x 627 (1.91:1). The workhorse format for traffic and lead gen campaigns.
Carousel ads: 1080 x 1080 per card. Square, consistent, every card the same size.
Event ads: 1776 x 444 for the event banner - a wide 4:1 header that displays on your event page.
Message ads: 300 x 250 for the banner that accompanies sponsored InMail. Small canvas; make the branding instantly readable.
Video ads: LinkedIn supports landscape (16:9), square (1:1), and vertical (4:5, 9:16) up to 5 GB in MP4 format. Duration can run 3 seconds to 30 minutes, but shorter wins - and since most people watch on mute, burn in captions.
The five sizing mistakes that make posts look amateur
1. Uploading low-resolution images. LinkedIn stretches small images to fill the space, producing pixelation. Always work at the recommended pixel dimensions or larger.
2. Ignoring aspect ratio. A beautiful photo in the wrong proportions gets auto-cropped, and LinkedIn's crop rarely lands well - it cuts off faces, text, and logos. Crop to the target ratio yourself before uploading.
3. Text too close to the edges. Different screens crop differently at the margins. When overlaying text on an image, leave a generous safe zone around all four edges.
4. Wrong file format for the content. Use PNG for graphics with text, logos, and sharp lines - compression artifacts on text are instantly visible. Use JPG for photographs - smaller files, and the quality loss is invisible in complex images.
5. Never previewing before publishing. What looks perfect in your design tool can crop differently in the live feed, especially on mobile. Post, check on your phone, and edit if needed - or better, preview with LinkedIn's own tools before publishing.
Frequently asked questions
What happens if I upload the wrong size? LinkedIn auto-crops or compresses to fit. Sometimes that's fine; often it produces blur, awkward framing, or amputated text. Resizing before upload is the only way to control the result.
What's the best image size for mobile? Portrait, 1080 x 1350 (4:5). It occupies the most feed real estate on a phone screen, and most of your audience is on mobile.
Do image dimensions affect reach? Indirectly, yes. LinkedIn's algorithm favors content that people engage with, and cropped or blurry images depress engagement. Correctly sized visuals aren't a ranking factor by themselves - they're a prerequisite for the engagement that is.
JPG or PNG? PNG for graphics, logos, and anything with text. JPG for photos. If in doubt: does it have sharp lines and text? PNG.
