LinkedIn Post Size 2026: Every Format, From LinkedIn's Help

LinkedIn post sizes for each format

Each row below is LinkedIn's own rule, as its help pages stated it on 26 October 2026. A ratio such as 4:5 means 4 units wide for every 5 tall; as a decimal, 4 divided by 5 is 0.8.

Images for a profile or a company Page follow rules of their own: a profile photo of 400 x 400 pixels and up to 8 MB, a profile banner of 1584 x 396, and for a company Page a 400 x 400 logo and a 1512 x 256 cover of up to 3 MB (a549049, a568217, a563309).

How the shape decides what LinkedIn cuts

The shape matters more than any of these numbers, because it decides what people see. LinkedIn's photo help puts it in two sentences: "The photo's aspect ratio can range from 3:1 to 4:5 (width:height). If the ratio is larger, the image will be centered and cropped to fit the max ratio." In plain terms, a picture wider than 3:1 or taller than 4:5 is cropped: its edges are cut away so it fits the frame, and the middle stays.

So divide your image's width by its height. Between 3.0 (three times wider than tall) and 0.8 (a little taller than wide), the feed, the stream of posts people scroll through, shows the whole picture. Outside that range, LinkedIn keeps the middle and cuts the rest.

A screenshot from an iPhone 15 shows how much that can be. It measures 1179 x 2556 pixels, a ratio of 0.46. At its width, the tallest frame LinkedIn allows is 1179 divided by 0.8 (the 4:5 shape), or 1474 pixels. The other 1,082 pixels of its height disappear, half at the top and half at the bottom, often with the line that mattered.

To keep it all, place the screenshot on a 1080 x 1350 background and scale it down until it fits inside. Then check the preview before you post, because "Uploaded photos can't be resized after they have been posted."

The 3:1 to 4:5 rule is also where the two famous sizes come from. LinkedIn recommends a width, "1080 (w) pixels", and the range of shapes; it publishes no height. 1080 x 1350 is the tallest shape at that width (exactly 4:5) and 1080 x 1080 the square. Any shape in between works just as well: a 1080 x 720 photo, the 3:2 of most cameras, shows in full too, only less tall in the feed.

1200 x 627 is for links, not photos

A link post shares the address of a web page. LinkedIn then shows a link preview, an image with the page's title and site name, built from the page itself. LinkedIn's help gives that preview "a 1.91:1 ratio and 1200 (w) x 627 (h) pixels", and asks website owners for an image of at least that size and at most 5 MB.

Two consequences follow. A post can carry "either a URL link or an image in a post, but not both at the same time", so a post with an attached photo shows no link preview. And the preview image is chosen on the website, in a line of its code called the og:image tag, not in LinkedIn's post editor. When a preview comes out wrong or stale, LinkedIn Post Inspector makes LinkedIn read the page again.

LinkedIn Pages, the accounts of companies, may be able to give a link its own image: their help page speaks of "custom images to a page post with a URL", again at 1.91:1, and says no more. For a Page post with a photo and no link, that rule "doesn't apply", so the photo rules above hold.

The near-miss numbers come from ads. 1200 x 628 is the size LinkedIn gives for a single image ad, the same 1.91:1 shape one pixel taller. 1200 x 626, also common in guides, appears on none of LinkedIn's specification pages.

Several photos in one post

A multi-image post holds 2 to 20 photos, which LinkedIn shows together in one frame that is at most 4:5. LinkedIn says "the post will have a greater visual emphasis on the first image", and that first image decides the layout:

• Two photos appear next to each other, each in its own shape.
• With three or more, a wide first image ("landscape or shorter than a 4:3 ratio") takes the top, and the rest line up in a row beneath.
• A tall or square first image fills a column on the left while the rest stack up on the right.

Photos in the second row get equal widths, and when the rows overflow the 4:5 frame, the bottom ones "will be cropped to fit". So put the photo that matters first, and give the others one shared shape so none of them gets cut.

Document posts, the "carousel" people mean

What most people call a LinkedIn carousel is a document post: a PDF, a PowerPoint or a Word file that readers swipe through page by page in the feed. LinkedIn's limits are 100 MB and 300 pages, one document per post, and a title. "PDFs with multiple sized pages must be fit to the same page size." Animations and videos inside the file "display as static images", and anyone who can see the post can download the document as a PDF.

LinkedIn publishes no pixel size for document pages. The 1080 x 1350 and 1080 x 1080 that most guides give are the photo shapes carried over, and they work well; the rule LinkedIn does state is that every page has the same size. Its help also advises to "convert files to PDFs whenever possible to ensure the highest quality upload". To decide between a photo, a document and a video for the same idea, see LinkedIn post formats.

The word carousel has a history. In July 2022 LinkedIn launched a real carousel post, made of swipeable photos and videos (Social Media Today). It stopped letting people create them on 26 June 2023, and from 14 December 2023, "any posts that contained a carousel will no longer be available" (LinkedIn's help, archived).

The paid Carousel Ad still exists, and its numbers are the ones that leak into document advice: 2 to 10 square cards, 1080 x 1080 recommended, 10 MB per card, and "Images will be scaled to 312 x 312px".

Video sizes, and the safe zone

LinkedIn's limits for a video in a post:

LinkedIn treats an animated GIF as an image. Its video player doesn't take them, and a post image can be a GIF of up to 500 frames. LinkedIn can also caption a video automatically in ten languages, and on a computer you can upload your own caption file.

On a phone, LinkedIn lays its buttons, the author's name and the post's text over the video. Its help asks you to "keep the edges (top, bottom, and sides) of your video free of key elements, text, and logos", and its diagram puts numbers on it for a 1080 x 1920 frame: 260 pixels at the top, 560 at the bottom, 112 on the left and 210 on the right. What remains is the safe zone, the part of the frame the app never covers, about 758 x 1100 pixels in the middle.

Video ads follow other limits (up to 500 MB and 30 minutes), which is where some guides' smaller file sizes come from.

Does 9:16 work on LinkedIn?

For video, yes. 9:16, the shape of a phone held upright, sits inside the accepted 1:2.4 to 2.4:1, and LinkedIn draws its own safe-zone diagram on a 1080 x 1920 frame. In the full-screen player of the mobile apps, LinkedIn warns that videos "with a larger aspect ratio may be cropped on the sides as well as at the top and bottom", so the safe zone matters most there.

For a photo, no. 9:16 is 0.56, taller than 0.8, so under LinkedIn's rule a 1080 x 1920 image is centred and cut to 1080 x 1350: 570 pixels go, split between the top and the bottom. Tall photos belong at 4:5.

Why an image looks blurry after posting

What people see is not always the file you uploaded. LinkedIn's ads help says images are "automatically scaled down regardless of the original size", and its photo help warns that "small, low-resolution photos may appear in a low-quality" form. Experts on Adobe's forums who compared a designer's file with the posted version found it had been compressed, with the damage worst in the reds (June 2021).

What helps:

• Upload at least 1080 pixels wide, LinkedIn's recommendation, so the picture is reduced rather than enlarged.
• Avoid thin red or other saturated text on a coloured background, the combination that suffers most.
• Export in RGB colours, the ones screens use, not CMYK, which is for print. "It needs to be RGB of course," as an Adobe Community Expert answered about a carousel PDF (September 2025).
• For images on a company Page, LinkedIn itself advises "a high-resolution JPEG instead of a PNG file".

Alt text

Alt text is a short written description of an image, which screen readers read aloud to people who can't see it. After adding a photo to a post, click Alt.text below it on a computer, or tap ALT in the mobile app, and type the description.

If you skip it, "LinkedIn may automatically add alt-text to images that don't have it." On a computer you're told when that happens; "you won't be alerted if you're uploading an image from a mobile device." LinkedIn's help sets no length. Its developer documentation allows up to 4,086 characters and recommends "less than 120".

Why the guides disagree

Most numbers that seem to contradict each other are real LinkedIn numbers, from another format, another product, or an older version of a help page. LinkedIn dates none of its changes; the dates below come from the Internet Archive's copies of its pages.

The rules on this page were read on LinkedIn's help pages on 26 October 2026, and each links to its source.
