The four numbers most people came for: profile banner 1584 × 396, Company Page cover 1512 × 256, square post 1080 × 1080, link preview 1200 × 627.

Everything else is below, grouped by where the image goes, each section opening with the answer. Every number was read off LinkedIn’s own help centre, ad specifications and developer documentation on 1 September 2026, and each one says which page it came from — because on two of these surfaces LinkedIn publishes more than one answer.

Why LinkedIn image sizes matter

Less than on other networks, and it is worth knowing why before you redo your whole library.

LinkedIn does not usually crop a post image. Its own guidance says the image “will be enlarged to fit the feed”, that images on mobile “won’t be cropped”, and that images of other ratios “will appear in full size with subtle white padding”. So the wrong shape in a post costs you screen space and sharpness, not the picture.

Two places it does cut: your profile banner, which LinkedIn trims to fit the screen, and the link preview, which falls back to a small left-hand thumbnail when the image is under 200 pixels wide. Those two are worth getting exactly right. For everything else, upload big and pick the shape that fills the most phone screen.

LinkedIn personal profile image sizes

Profile photo: 400 × 400

400 × 400 pixels minimum, anything up to 7680 × 4320 accepted, under 8 MB, PNG or JPG. It displays as a circle, so centre the face or the logo and expect the corners to go. If it looks soft, LinkedIn’s own fix is to upload a larger file rather than a compressed one. GIFs are refused here.

Background banner: 1584 × 396

1584 × 396 pixels, 4:1, JPG or PNG, under 8 MB. LinkedIn calls it the background photo; most people call it the banner. GIFs are refused here too — LinkedIn’s own sentence is “We don’t support GIFs.”

What gets cropped, and the safe zone

The crop matters more than the size. LinkedIn says a cover image “might be adjusted to fit the screen, which might trim the image horizontally or vertically”, and its advice is to keep key details away from the edges, especially the lower-right corner, because putting them in the centre “ensures that it is always visible”.

The 1200 × 300 safe zone quoted around the web is somebody’s measurement, not LinkedIn’s. Centre your text, leave the corners empty, and the box does not need to be exact.

LinkedIn Company Page image sizes

Page logo: 400 × 400

400 × 400 recommended, 268 × 268 minimum, PNG or JPEG, 3 MB maximum. That 3 MB cap covers every Page image. One thing worth designing for, in LinkedIn’s own words: the logo is shown on both light and dark backgrounds, and a transparent logo is placed on white.

Page cover: 1512 × 256

1512 × 256 pixels, PNG or JPEG, 3 MB maximum.

This is the surface with three answers in circulation, and the reason is that the number changed.

  • 1128 × 191 is a display size from LinkedIn’s older layout. Still copied into guides, and it will look soft on a modern screen.
  • 1512 × 256 is what LinkedIn’s help page says today — that page carries a “last updated: 2 weeks ago” stamp.
  • 4200 × 700 is what guides published through the middle of 2026 say, and cached copies of the same LinkedIn help answer still show it. They were right when they were written.

Upload 1512 × 256. If you want the file to survive the next change, keep the same ~5.9:1 shape at a higher resolution: LinkedIn scales a cover down to fit, and its own advice is to use “a high-resolution JPEG instead of a PNG file” — the opposite of what most design advice says.

Life tab images: 1128 × 376 and 502 × 282

Main image 1128 × 376, custom modules 502 × 282, company photos 900 × 600 recommended (264 × 176 minimum). Same 3 MB cap, same two formats. The Life tab only exists on Pages enhanced with Career Pages, which is a paid product — if you do not have it, skip this row.

LinkedIn post image sizes

Single image post: 1080 × 1080 or 1080 × 1350

1080 × 1080 for a square, 1080 × 1350 for a portrait. Both are industry convention, and here is the honest part: LinkedIn publishes no size at all for a plain image post.

So the shape is your choice and only the resolution really matters — 1080 pixels wide is enough that nothing softens. Portrait is the better default on a phone: 4:5 takes about a third more vertical space than a square and roughly twice a 16:9 landscape.

Multi-image post: how many images one post can carry

Up to 20 from the LinkedIn app. Through a scheduling tool it depends on which LinkedIn API the tool was built on, and nine is common.

LinkedIn’s current publishing endpoint documents the app’s number exactly: a multi-image post takes “a minimum of 2 images and a maximum of 20 images”, each under 36,152,320 pixels, as JPG, GIF or PNG. The older share endpoint — the one LinkedIn’s own documentation now titles “UGC Post API (Legacy)”, and the one many integrations including ours still publish through — documents no image count at all. Its media field is simply “an array”, so you find the ceiling by hitting it. We hold ours at nine and say so on the tool that takes the files: that is our integration’s ceiling, not LinkedIn’s.

One limit is LinkedIn’s own and applies whatever tool you use: a single share carries one kind of media. Attach photos and a video to the same post and LinkedIn answers “Cannot mix media types”. Your tool then either publishes the video and quietly drops the photos, or refuses the post and tells you why.

1200 × 627 pixels, 1.91:1. This is a different image from a feed photo: it is the card LinkedIn builds when your post carries a URL, and it is the one feed number LinkedIn does publish.

The rule to remember is the minimum. The image must be more than 200 pixels wide; below that, LinkedIn renders a small thumbnail to the left of the text instead of a card above it.

Square 1080 × 1080 or portrait 1080 × 1350 slides, exported as one PDF, up to 100 MB and 300 pages. A LinkedIn carousel is not a multi-image post — it is a document post, and what you upload is a document.

LinkedIn also accepts PPT, PPTX, DOC, DOCX, ODT, ODS and PPSX, but a PDF is the only one whose page shape you fully control. Use one shape for every page or the deck jumps as people swipe.

Worth checking in whatever tool you use: some schedulers publish a “carousel” as a document post and others as a multi-image post. They look similar in the feed and report differently in analytics.

Article cover: 1920 × 1080

1920 × 1080, 16:9. LinkedIn says article covers are “cropped to a 16:9 aspect ratio” and accepts JPEG, JPG, PNG and WEBP for this one surface. GIFs “can no longer be used for the cover photos”.

A second LinkedIn help page gives a different number for the same thing — 2000 × 600 — and caps images inside an article at 10 MB. Use 1920 × 1080: it is on the newer page and it matches the crop that page describes.

LinkedIn video specs

MP4, 256 × 144 up to 4096 × 2304, aspect ratio between 1:2.4 and 2.4:1, 3 seconds to 15 minutes on desktop or 10 minutes in the mobile app, 75 KB to 5 GB. LinkedIn also documents 10–60 fps and a bit rate of 192 kbps to 30 Mbps, and accepts MOV, AVI, WEBM, MKV and WMV alongside MP4.

Two practical notes. Vertical video at 1080 × 1920 sits inside that aspect range and takes the whole phone screen, which is why it is the shape most brands now upload. And a scheduling tool’s own ceiling is far below 5 GB — ours is 64 MB per video, and we cannot check duration or frame size before sending at all, because nothing in our pipeline reads a clip’s metadata. We say that on the tool rather than pretending to check.

LinkedIn ad image sizes

If you also run Sponsored Content, the specs are stricter and — this is the irony of the whole subject — far better documented than the organic ones.

Single image ad: JPG, PNG or GIF, 5 MB maximum, up to 7680 × 4320. Recommended sizes are 1200 × 1200 for a square (1:1), 1200 × 628 for horizontal (1.91:1) and 720 × 900 for vertical (4:5). An animated GIF must be 250 frames or shorter, and an image under 401 pixels wide is shown as a thumbnail.

Carousel ad: 2 to 10 cards, JPG or PNG, 1:1, at least 1080 × 1080, 10 MB per card. Cards are displayed at 312 × 312, so anything small in the artwork disappears.

Document ad: PDF, DOC, DOCX, PPT or PPTX, up to 100 MB and 300 pages — the same caps as an organic document post.

File size and format limits

The five file-size caps

There is no single answer, and that is not a simplification: LinkedIn’s own pages give five caps, by surface.

Cap Applies to LinkedIn’s page
3 MB every Company Page image: logo, cover, Life tab Image specifications for your LinkedIn Pages, updated 2 weeks ago
5 MB a single image ad Single image ads advertising specifications
8 MB profile photo and background photo Add or change the cover image on your profile
10 MB images inside a published article, and each carousel ad card Publishing Platform FAQ / carousel ad specs
100 MB media in a post, and documents Media file types supported on LinkedIn, updated a year ago

The resolution ceiling splits the same way: the media-types page caps images at 36 megapixels, the profile media page at 120 megapixels. Design against 36 — it matches the 36,152,320-pixel figure in LinkedIn’s developer documentation, so it is the number two sources agree on.

LinkedIn's media file types page: WEBP ticked for Android only, and notes capping files at 100 MB, 300 pages and 36 megapixels

Which formats LinkedIn accepts

  • JPEG and PNG work on every surface. For Page images LinkedIn asks for one of the two and nothing else, and recommends a high-resolution JPEG over a PNG.
  • GIF is fine in a post, capped at “500 frames or 36,152,320 pixels” per the help centre and at 250 frames per the developer docs and the ad specs. Refused on your profile photo, refused on your background photo, and no longer allowed on an article cover.
  • WebP is listed as supported on Android and blank for desktop and iOS — yet the article-cover page lists WEBP as supported. Convert it to JPEG and the question goes away.
  • HEIC, what an iPhone shoots by default, is listed for iOS only. Convert it before it reaches a scheduler.

Why you will find three different sizes for the same surface

Three reasons, and none of them is that the guides are careless.

Display size versus upload size. 1128 × 191 is how wide the old Page cover was rendered, not what LinkedIn wanted you to upload. A guide that copies a display size produces a soft image on a retina screen.

LinkedIn changes the numbers and does not date the change. The Page cover spec moved recently; its help page shows only “last updated: 2 weeks ago”, which makes every guide written before that stale rather than wrong.

LinkedIn’s own pages disagree. An article cover is 1920 × 1080 on one help page and 2000 × 600 on another. The resolution ceiling is 36 megapixels on one and 120 on another. A GIF is 500 frames in the help centre and 250 in the developer docs. When two of the vendor’s own pages disagree, every guide downstream picks one and looks confidently wrong to whoever read the other.

The defence is the same in all three cases: prefer the page with the newest stamp, prefer the number two sources agree on, and when the shape is unchanged, upload at the higher resolution.

Common LinkedIn image mistakes

Designing the banner for your own screen. It is trimmed differently at every window width, and the lower-right corner is where LinkedIn itself warns you not to put anything.

Using a display size as an upload size. Every “why is my banner blurry” thread ends here. Upload two to three times the rendered width and let LinkedIn scale it down.

Landscape by default in the feed. A 16:9 image is not wrong, it just buys about half the screen height of a 4:5 one on a phone, where most of the feed is read.

One image for every network. LinkedIn pads almost any shape; Instagram refuses anything outside 0.75:1 to 1.91:1. The refusal in our own logs reads “Aspect ratio 1.97:1 is outside Instagram’s allowed range (0.75 to 1.91)”. A tall image LinkedIn accepts happily is the one Instagram bounces.

Trusting a documented file cap in either direction — which deserves its own section.

What actually gets a LinkedIn image rejected

Rarely the size. From a year of publishing other people’s posts, the documented number is often not the binding one, in both directions.

Instagram’s docs say 8 MB. We wrote that down, and it killed the Instagram half of four production posts before we measured what Meta actually takes — an 11.79 MB PNG went up without a complaint. Facebook documents 4 MB and Threads 8 MB, and we have watched both publish the same 12 MB image.

LinkedIn is the opposite case, and the reason we hold no file-size rule for it at all: its 100 MB and 36 megapixels sit above our own ceiling of 32 MB per image, so LinkedIn’s limit can never be the thing that stops you. Your tool’s limit is the one you will hit, whichever scheduler you use.

The PostPost.ai social media post checker, which reports for each network whether an image publishes as it is, gets trimmed, or is refused

To check one file instead of reading a table, our post checker runs the same code our publish path runs: drop the image in and it reports, per network, whether the file goes out as it is, gets trimmed, or is refused — with the reason in the network’s own words. Nothing is uploaded; your browser measures the file and sends only its size, type and dimensions.

LinkedIn image size FAQ

What is the best image size for a LinkedIn post in 2026? 1080 × 1080 for a square, 1080 × 1350 for a portrait. LinkedIn publishes neither — it accepts what you send and pads other ratios — but both are large enough to stay sharp, and portrait takes the most room on a phone.

What size is a LinkedIn cover photo? It depends which cover: 1584 × 396 for a personal profile, 1512 × 256 for a Company Page, 1920 × 1080 for an article. Three surfaces, three shapes, one word.

What is the maximum size of the LinkedIn banner in 2026? 1584 × 396 pixels, under 8 MB, JPG or PNG. There is no larger banner spec; a bigger file is scaled down.

How do I make a LinkedIn banner fit? Match 4:1 exactly and keep every word in the middle. LinkedIn trims the edges to fit the screen and warns specifically about the lower-right corner.

Does 1920 × 1080 work on LinkedIn? Yes — it is LinkedIn’s own recommendation for an article cover. In a post it works but wastes space: a 16:9 image takes about half the height of a portrait one on a phone.

Is a LinkedIn post 16:9? Only a link preview has a fixed shape, and it is 1.91:1 (1200 × 627), close to 16:9 but not the same. A plain image post has no fixed ratio.

How do I resize a photo to fit LinkedIn? Export at the target size rather than scaling a small file up. LinkedIn’s own advice for a blurry cover is to upload a larger file, as a high-resolution JPEG rather than a PNG.

Getting the shape right before you publish

One image reused across every network is where a table stops being enough. X takes four images per post, LinkedIn nine through the endpoint we use, Instagram ten. Text splits the same way — LinkedIn’s commentary stops at 3,000 characters, which our LinkedIn character counter counts the way the API does.

The PostPost.ai LinkedIn post preview, with a 3,000-character counter and an images control capped at nine

Two things are worth having whatever tool you use. A per-channel preview, so you see the crop before it publishes — ours is the LinkedIn post preview, which also shows the ~140-character cut where LinkedIn hides the rest behind “…see more”. And a tool that reports a rejected file in the network’s own words rather than as a generic failure.

If you post carousels too, the Instagram carousel limit is this same story in another network: the app allows 20 slides, every scheduler stops at 10, and the reason is the API.

If you would rather not think about shapes at all, PostPost.ai reads your brand from your own website and writes a month of on-brand posts, each one already at the right shape for the network it goes to.
