How to Post on LinkedIn: Formats, Length and Ideas for Profiles and Pages

The button is easy to find. The hard part is choosing a format, knowing what fits, and writing something a colleague stops to read. This guide covers both a personal profile and a company Page, and says where they differ.

How to post on LinkedIn from your profile

The steps below follow LinkedIn Help, "Post and share updates" (checked November 2026, source).

On desktop

1. Click Start a post at the top of your LinkedIn home page.
2. Click the menu with your name to choose who can see the post, who can comment, and whether to turn on Brand Partnership.
3. Write your text. Add an emoji, media, an event or a celebration, or use the + icon for a job, a poll, a document or a service.
4. To publish later, click the clock icon and pick a time.
5. Click Post.

In the app

1. Tap Post in the navigation bar.
2. Tap the Anyone menu next to your photo to set visibility, comments and Brand Partnership. If you manage a Page, this is also where you choose to post as yourself or as the Page.
3. Write in the "Share your thoughts" box. The media icon adds a photo or a video; the + opens Media, Event, Celebration, Job, Poll or Document.
4. Tap the clock icon to schedule, or tap Post to publish now.

How to post on LinkedIn as a company Page

Only a Page super admin or content admin can post as the Page. Without one of those roles, you have to request admin access first, according to LinkedIn Help, "Post as your LinkedIn Page" (checked November 2026, source). If the Page or the roles are not set up yet, start with our LinkedIn profile and company Page guide.

A Page can post text, images, videos, documents and a website or article URL, and it can mention members and other Pages.

On desktop: go to your Page super admin or content admin view, click Page posts in the left menu, then Start a post. Type text or paste a URL. The pencil icon uploads a photo, video or document. Click the Page name to choose Anyone or Targeted Audience and to set Comment Control, then click Post.

In the app: open the admin view, tap Dashboard in the top left and choose Page posts. Tap Post in the top right, add an image or tap Add a document, set Comment Control if you want, and tap Post.

You can also save the post as a draft or schedule it.

LinkedIn post formats and their limits

Every format starts from the same box; what changes is the attachment. The limits below come from LinkedIn Help (checked November 2026).

Format	Limit	Source
Text	Up to 3,000 characters per post	Post and share updates
Image or multiple images	Up to 20 photos in one post, up to 5 MB per upload, at least 552 x 276 px, 1080 px wide recommended, aspect ratio from 3:1 to 4:5	Share photos on LinkedIn
Video	MP4, from 75 KB to 5 GB, at least 3 seconds, resolution from 256 x 144 to 4096 x 2304, aspect ratio from 1:2.4 to 2.4:1	Video sharing troubleshooting, Video specifications for Pages
Document	One per post; PDF, PPT, PPTX, DOC or DOCX; up to 100 MB and 300 pages	Document uploads FAQ
Link	Paste the link or type the URL into the post; the preview image sits in a 1.91:1 frame, 1200 x 627 px	Share articles or links
Poll	2 to 4 options; runs for one day, three days, one week (the default) or two weeks	Create LinkedIn Polls, LinkedIn Polls
Article	Up to 125,000 characters	Posting updates vs. publishing articles

A few notes that the table cannot hold:

• Documents are the format people use for the swipeable slides you see in the feed. Building one is its own topic, covered in how to make a LinkedIn carousel.
• Polls show the creator who voted and how. On a Page, every admin sees it.
• Video length is left out on purpose: LinkedIn's help pages give different maximums. Check the upload screen before you film something long.

Post or article?

A post is the everyday unit: up to 3,000 characters, shown in the feed. When your text runs longer, LinkedIn Help suggests writing an article instead (source). Articles go up to 125,000 characters, and members as well as Page super admins and content admins can publish them.

Newsletters sit one step further. All LinkedIn members can create one. Pages have to meet criteria, including an audience base, recent original posts and a good record with LinkedIn's Professional Community Policies; Pages with more than 150 followers and/or connections are eligible to be evaluated (source).

How long should a LinkedIn post be?

The hard cap is 3,000 characters. The cap that matters more is the one you cannot see: the feed shows only the first lines of a post, and the rest sits behind "see more". LinkedIn does not publish where that cut falls, and the numbers that circulate online disagree with each other, so write as if your reader sees one or two lines and decides from there.

Beyond that, match length to the point. An announcement can be three lines; a project lesson can use most of the 3,000 characters if each paragraph earns the next.

How to write a LinkedIn post

Most posts that work have three parts.

The hook. The first line has one job: earn the tap on "see more". State the result, the surprise or the question up front. Skip the warm-up ("I have been thinking a lot lately about...").

The body. Make one point, in short paragraphs with a blank line between them; a wall of text on a phone looks like work. Give one concrete detail: a number you can back up, a step, a mistake.

The close. End with one ask: a question to answer in the comments, a link to open, a document to download. Two asks split the reader.

Here is the structure at work, for a fictional bookkeeping firm in Denver:

> We stopped sending clients a monthly report. Questions went down. > > For years, we emailed a 12-page PDF on the 5th of each month. Almost nobody opened it, and the same three questions arrived by email every week. > > So we replaced it with a five-line summary: cash in, cash out, what changed, what to watch, what we need from you. > > Clients now reply to the summary instead of calling us. > > If you run a firm, what does your client report look like?

A few habits help every post:

• Tag a person or a Page only when they are part of the story.
• Put the link where your close asks for it, and say what the reader gets on the other side.
• When you post matters too. Our guide on the best time to post on LinkedIn covers that.

LinkedIn post ideas by goal

Twenty ideas, grouped by goal, each marked for a profile, a Page or both. A profile speaks as a person and a Page as the company, so opinions and personal stories fit profiles better.

Build authority

1. A mistake you see clients make, and the fix. (Both)
2. A checklist for a task your customers often do, as a PDF document. (Both)
3. A term from your field explained in five lines. (Both)
4. Three questions to ask before hiring someone in your field. (Profile)

Show the work behind the scenes

1. How a typical project moves from first call to delivery. (Page)
2. A photo series of the team at work, as a multi-image post. (Page)
3. A tool or process you changed this quarter, and why. (Both)
4. A new hire's first week, told by the new hire. (Page)

Share client results

1. A before and after, told as a story, with the client's permission. (Both)
2. A short case study as a PDF: problem, what you did, outcome. (Page)
3. A client quote with a photo, when the client agrees to it. (Page)
4. The question a client asked that changed how you work. (Profile)

Give an opinion

1. A common practice in your industry you disagree with, and what you do instead. (Profile)
2. A poll on a choice your audience faces, then a follow-up post with your take. (Both)
3. What you would tell someone starting in your field today. (Profile)
4. A reaction to a piece of news in your sector, in three points. (Both)

Invite people in

1. An open role, with what the person will actually do in month one. (Page)
2. An event or webinar, posted with the LinkedIn event feature. (Page)
3. A free resource for download, as a document post. (Both)
4. A call for people to share their own experience on a topic you are researching. (Profile)

Profile or Page: what changes

The posting box looks the same, but two things differ, both from the LinkedIn Help articles cited above:

• Who can post. Any member posts from a profile. Only super admins and content admins post as a Page.
• Audience controls. A profile chooses who sees the post, who comments and whether it is a brand partnership. A Page chooses between Anyone and Targeted Audience, plus Comment Control.

Where Zynta Flow fits

Zynta Flow publishes to LinkedIn as text, image, video, document (PDF), multiple images and link, on a personal profile and on a company Page. If your Page is the main channel, see how to publish to a LinkedIn company Page automatically.

Native long-form articles stay on LinkedIn: its posting API has no route to publish them.

Scheduling is free in Zynta Flow, and publishing costs 5 credits per post per network. You can also have the AI build an editorial plan for LinkedIn, from 1 to 7 posts per week over 1 to 12 weeks. To set up the queue, see how to schedule Instagram and LinkedIn posts.
