The phrase 'LinkedIn post size' hides several placements. Identify whether you mean a shared URL image, uploaded image, article cover, document, or video before exporting.

## There is no single LinkedIn post image size

**Answer:** LinkedIn publishes different guidance for different sharing surfaces, so first name the placement and asset type.

A post can contain a photo, a link preview, a document, an article, or video. Their media rules and presentation differ. LinkedIn Help recommends a 1.91:1 image for certain Page URL previews, while its article publishing FAQ lists a 2000 by 600 pixel optimal cover photo. Those are two named contexts, not a general rule for every image attached to a member's post.

The starting question is therefore 'where will this image appear?' rather than 'what is the LinkedIn image size?' If you are sharing a web URL from a Page, use the Page preview guidance. If you are designing an article cover, use the article tool guidance. If you are uploading a document or photo, check the current upload controls and preview for that format.

The matrix's intent and top-10 evidence remain incomplete, so this guide does not claim these are all possible specs or a ranking opportunity. Its practical value is a placement decision method and a source ledger that prevents recommendations from being detached from their original context.

- Uploaded feed photo or multi-image post
- Article cover image
- Document or carousel-like upload
- Video thumbnail and video file

## Page post with a website URL preview

**Answer:** LinkedIn Help recommends a 1.91:1 image, with 1200 by 627 pixels as the example, for a customized LinkedIn Page URL preview.

LinkedIn's help page about customizing a Page post preview says to use a 1.91:1 ratio, illustrated as 1200 by 627 pixels. It also notes a width threshold for larger preview display and says mobile images are shown in full rather than cropped, with subtle padding when the ratio differs. These statements are scoped to a Page administrator customizing a URL preview.

This should not be confused with the image on the destination website itself. LinkedIn may use Open Graph metadata to create a preview, and Page admins may be able to replace the preview image in the composer. Check that the selected image matches the link and that title and destination are accurate before posting. A correctly sized preview cannot repair an outdated, unavailable, or mismatched landing page.

Do not assume that the same 1.91:1 recommendation governs a standalone photo post or every member's profile. The source names a Page-post URL scenario. If your use case differs, consult the matching current help document and test the actual preview.
- Documented example: 1200 x 627 pixels
- Use for Page URL-preview context only
- Inspect image, title, URL, and mobile appearance

## Article cover images use another canvas

**Answer:** LinkedIn's article publishing FAQ lists 2000 by 600 pixels as an optimal cover image size for articles.

An article cover is a wide banner-like image, not the same asset as a 1.91:1 link preview. The LinkedIn Publishing Platform FAQ lists JPG, static GIF, and PNG as supported article image formats and says the file-size limit for images added to articles is 10 MB; it names 2000 by 600 pixels as the optimal cover size. The help page is older, so verify the current article editor and preview before preparing a release asset.

At 2000 by 600, the ratio is 10:3, or about 3.33:1. That very wide shape can crop differently in cards and article views. Keep key text and subjects away from the outer edges as a prudent composition choice, then inspect how the current editor displays the uploaded cover. That advice is not an official pixel-safe margin.

A cover image carries context for a long-form article. It should be relevant and licensed, and any text embedded in the art must remain legible at the smaller display size. If the cover depends on details too small to read in a feed preview, place the essential meaning in the article title and introduction too.
- Published article cover example: 2000 x 600
- Source page lists 10 MB and JPG/static GIF/PNG for article images
- Verify the current article editor before export

## Uploaded photos and document posts need a different review

**Answer:** LinkedIn's media reference lists supported file types and upload limits, but it does not prescribe one universal aspect ratio for all organic photos and documents.

LinkedIn's current media file-type reference lists JPEG, PNG, WEBP, and other formats across devices, and states a 100 MB file limit, a 300-page document limit, and a 36-megapixel maximum image resolution. These are file and upload constraints, not a target composition. Device support differs for some media types, so check the current table before relying on a specific extension.

A document post can function as a sequence of pages, but the documentation cited here does not define one universal document-slide ratio. Choose a page canvas that keeps type readable and the sequence coherent, then upload a test draft and inspect it in the current feed viewer. Do not label a chosen landscape or portrait page size as LinkedIn's official carousel dimension without a source for that exact claim.

For a single uploaded photo, preview the actual composer and post. The Page URL image guidance cannot simply be copied across. Keep the original high-resolution asset, prepare the intended crop, and inspect on desktop and mobile if those are the audiences you need to serve.
- Supported media list is not a composition recommendation
- Documents: check page count, readability, and actual preview
- Photo crop: inspect the exact upload surface

## Video dimensions are a separate LinkedIn question

**Answer:** LinkedIn's official video-sharing ranges include several shapes; select the rule for organic uploads or advertising rather than mixing them.

LinkedIn Help's video-sharing troubleshooting page lists an aspect ratio range from 1:2.4 through 2.4:1, alongside resolution and duration limits for the upload path it documents. LinkedIn's video-ad specifications separately provide recommended ad ratios including landscape, square, 4:5 vertical, and 9:16 vertical. Advertising recommendations do not define every organic video display or imply that an organic video will be cropped the same way.

A video's thumbnail may also have a rule tied to a specific ad placement. The ad source states that the thumbnail ratio and resolution should match the video for that ad context. Do not export a thumbnail using that requirement for unrelated organic posts without checking their own composer.

If a LinkedIn post contains a video, keep the video dimensions, cover or thumbnail, and any external preview image as separate fields in your asset record. Each belongs to a different surface and may be rendered differently.
- Organic sharing and video advertising are distinct contexts
- Thumbnail requirements may be placement-specific
- Record video and preview image properties separately

## A placement-first export checklist

**Answer:** Use a short decision tree to select a source, then verify its crop in LinkedIn's current preview.

First record the publishing surface and who is posting: a member profile, LinkedIn Page, article, document, or Campaign Manager ad. Next identify whether the media is an uploaded image, a URL preview, a document page, or video. Consult the matching official source and record its access date. Avoid carrying dimensions from another row of the decision tree.

For each export, save the source filename, output dimensions, ratio, format, file size, destination, version, and reviewer. Inspect text, logos, faces, and essential product details in the actual preview. Recheck the link, title, and page metadata when posting a URL. If the account uses a placement that the official guide does not cover, mark the spec as unconfirmed rather than guessing.

This guide intentionally avoids a generic 'safe-zone' overlay for all LinkedIn formats. LinkedIn video help does advise keeping key elements away from edges where interface elements may overlap, but it does not make one fixed inset valid for every device and format. Use the destination preview as the visual check.
- Name profile, Page, article, document, or ad
- Match file type and source to placement
- Record dimensions and version
- Inspect current preview and link metadata

## Worked example: a fictional consulting Page

**Answer:** A fictional Page chooses different images for a URL preview and an article cover instead of reusing one crop blindly.

Suppose 'Meridian Field Notes' is a fictional consulting Page sharing a blog post and separately publishing a native LinkedIn article. For the URL post, the designer prepares a 1200 by 627 image based on LinkedIn's Page preview guidance. For the native article, the designer prepares a separate 2000 by 600 cover based on the article FAQ. Both use the same approved illustration but crop to different compositions.

The Page admin checks that the URL title and destination are current and reviews the generated preview. The article editor checks the cover after upload and confirms the title remains legible in the actual display. These are fictional workflow steps, not an observed LinkedIn result. No real company, asset, post, or preview is represented.

If the article editor has changed or the available account controls differ, the team records that uncertainty and checks current LinkedIn Help. A dated source and an actual preview are both needed to claim the workflow has been verified.
- URL preview: 1200 x 627 example
- Article cover: separate 2000 x 600 example
- Review each surface independently

## Get a source-bounded size review

**Answer:** Ask a reviewer to identify unknowns and cite the precise placement guide rather than return a context-free pixel recommendation.

Prompt: 'Review this planned LinkedIn asset. Publisher and placement: [member/Page/article/document/ad]. Asset type: [image/video/document/URL preview]. Intended audience devices: [details]. Source file dimensions and format: [verified metadata]. Current official source links: [URLs and dates]. Return the correct source-specific recommendation, show ratio arithmetic, identify whether it is an organic or ad rule, list unsupported assumptions, and give preview checks. Do not invent a universal feed size or safe-zone margin. If the official source does not specify this exact placement, say so. Mark any example fictional. A human reviewer will verify the current help page and inspect the real uploaded preview.'

The prompt does not test a LinkedIn profile or Page. Supply real metadata and a source for the relevant publishing surface. Have the person responsible for the account confirm permissions and current controls, especially for Page administration and Campaign Manager.

## Which image guidance belongs to which placement?

Use these examples only in the named contexts; check the linked official source and current preview before publishing.

| Placement | Officially documented example | Important boundary |
| --- | --- | --- |
| LinkedIn Page URL preview | 1.91:1, illustrated as 1200 x 627 | Not a universal organic photo-post ratio |
| Article cover | 2000 x 600 optimal cover example | Older help page; confirm current editor |
| Uploaded media/document | File type and upload limits are documented | Those are not a universal slide canvas |
| Video ad | Placement-specific landscape, square, 4:5, and 9:16 options | Do not apply ad specs to every organic upload |

## Frequently asked questions

### What size should a LinkedIn post image be?

It depends on placement. LinkedIn's Page URL-preview guidance gives a 1.91:1 example, while article covers use a different recommendation. Check the exact surface.

### Is 1200 by 627 the right size for all LinkedIn posts?

No. LinkedIn recommends that size for certain Page post URL previews. It is not a universal requirement for photos, documents, article covers, and videos.

### What size is a LinkedIn article cover?

LinkedIn's article publishing FAQ lists 2000 by 600 pixels as an optimal cover example. Verify the current article editor because the help page is older.

### What size should LinkedIn carousel slides be?

The official sources reviewed here do not establish a single universal organic document-slide ratio. Choose a readable page design and inspect the actual document post preview.

### Can I use vertical images on LinkedIn?

LinkedIn supports multiple media shapes in some contexts. Current advertising specs include vertical video options, but those ad rules should not be generalized to every organic image surface.

### Does a correct image size guarantee LinkedIn will display it as expected?

No. Account type, placement, device, metadata, and the current renderer affect display. Review the actual preview and post.
