LinkedIn Post Size: The Complete 2026 Guide

LinkedIn allows up to 3,000 characters in a regular post.

That is the official maximum for a standard LinkedIn feed update.

The limit is based on characters, not words, so your total can include letters, spaces, punctuation, line breaks, symbols, and emojis.

A post with 2,900 characters is within the published limit. A post exceeding 3,000 characters will need to be shortened before it can be published as a regular update.

How many words is 3,000 characters?

There is no exact conversion because word lengths vary.

For example:

• A paragraph containing many short words will fit more words into 3,000 characters.
• A technical post containing longer words and terminology will fit fewer.
• Extra line breaks, punctuation, and formatted symbols also use part of your character allowance.

As a rough illustration, 3,000 characters may represent around 400–500 English words, depending on writing style.

However, a character counter is more reliable than estimating from the number of words.

Does your LinkedIn post need to be 3,000 characters long?

Not at all.

The character limit tells you how much LinkedIn permits. It does not tell you how much your audience wants to read.

A short announcement may need only a few sentences.

A personal experience or case study might benefit from several paragraphs.

A technical explanation may require more space.

The best approach is to write enough to communicate the idea clearly without adding unnecessary text simply to reach a certain length.

LinkedIn post length examples

When you scroll through LinkedIn, longer posts often appear collapsed.

Instead of displaying everything immediately, LinkedIn shows an opening section followed by a “see more” option.

Many online guides offer an exact character number for this cutoff.

The problem is that LinkedIn does not publish one universal, guaranteed “see more” character limit.

The visible text can vary according to device, screen width, feed layout, and interface changes.

A post may therefore appear differently on desktop and mobile.

How to write a better opening

Because the cutoff is not fixed, concentrate on the first one or two lines instead of trying to hit a supposedly perfect character count.

Compare these openings:

The second example gives readers an immediate reason to pay attention. You can then use the rest of your LinkedIn post to explain what happened, what you learned, and why it matters.

Practical formatting tips

• Keep your opening understandable on its own.
• Use short paragraphs where they make reading easier.
• Avoid placing an unnecessary introduction before your main point.
• Keep important words and context together.
• Preview your post before publishing because the visible cutoff may differ between devices.

Images are another important part of LinkedIn post sizing.

The most common mistake is assuming that there is only one correct image dimension for every post.

In reality, a directly uploaded photo, a shared link image, and a multi-image post can have different display requirements.

LinkedIn's official guidance for uploaded photos supports aspect ratios from 3:1 to 4:5. It recommends images at least 1080 pixels wide for better presentation, with specific minimum dimensions and upload limits.

1. Square LinkedIn image: 1080 × 1080 pixels

A square image uses a 1:1 aspect ratio. It is a practical choice for:

• Professional announcements
• Educational graphics
• Simple infographics
• Quote graphics
• Branded content

Square images are convenient because the layout is balanced and can be reused across many content types and social networks.

2. Portrait LinkedIn image: 1080 × 1350 pixels

A portrait image uses a 4:5 aspect ratio. This shape can be useful when your design needs more vertical space.

For example, you might choose it for a checklist, a short visual guide, or a graphic with several clearly separated sections.

The extra height gives you more room to arrange information without forcing everything into a square.

However, remember that multi-image layouts can crop or rearrange individual images, so keep essential text away from the edges.

3. Landscape LinkedIn image: 1200 × 627 pixels

A landscape image at approximately 1.91:1 is commonly used for wide graphics and link previews. It can work well for:

• Website article previews
• Wide illustrations
• Business announcements
• Graphs and charts
• Featured blog images

There is an important distinction here: LinkedIn specifically recommends 1200 × 627 pixels for custom images associated with Page posts containing a URL. That does not mean every directly uploaded photo must use these exact dimensions.

Which LinkedIn image size should you choose?

For a standalone professional graphic, start with 1080 × 1080 pixels if you want a simple, flexible layout.

Choose 1080 × 1350 pixels when vertical space improves the design.

Use approximately 1200 × 627 pixels for a wide link-preview-style image.

Before publishing, check that labels, faces, logos, and important details remain visible. The correct dimensions help preserve the design, but they do not guarantee more impressions or engagement.

Dimensions describe the width and height of an image. File size describes how much storage the image uses. Both matter.

LinkedIn's photo-sharing guidance states that uploaded photos must meet its minimum dimension requirements and have a file size no greater than 5 MB.

Supported image formats vary by device, but JPEG and PNG are common choices.

• For a photo with many colors, JPEG is often suitable.
• For an infographic containing text, shapes, or diagrams, PNG can be useful because it can preserve sharp edges without compression artifacts.

Before uploading an image:

1. Export it at a suitable resolution (at least 1080 pixels wide).
2. Confirm that the aspect ratio is appropriate (between 3:1 and 4:5).
3. Check whether the text is readable on a mobile screen.
4. Compress the file when necessary to remain well under the 5 MB ceiling.
5. Avoid putting important information too close to the outer edges.

Always check LinkedIn's current upload requirements if you are working with unusually large or specialized files.

Videos add another set of requirements to consider. A video that looks good in an editing application may not display the same way after uploading to LinkedIn.

The most useful starting point is to choose the correct video orientation.

Recommended production dimensions

These are useful production formats, not exclusive LinkedIn upload dimensions.

LinkedIn's published video upload requirements

According to LinkedIn's Help Center:

• Maximum video file size: 5 GB
• Maximum video duration: 15 minutes
• Minimum duration: 3 seconds from desktop, or 2 seconds from the mobile app
• Supported aspect-ratio range: 1:2.4 to 2.4:1
• Resolution range: 256 × 144 to 4096 × 2304 pixels
• Supported frame rates: 10–60 fps

MP4 is a practical format to use when exporting a video for LinkedIn.

Keep subtitles, labels, and other critical content away from the outer edges, where interface controls can overlap the video.

Should you use vertical or horizontal video?

There is no single format that is automatically best for every LinkedIn audience.

Vertical video (9:16) is suitable for content created primarily for mobile viewing.

Landscape video (16:9) can work well for presentations, screen recordings, interviews, or detailed visual demonstrations.

Square video (1:1) is another useful option when you want a compact, balanced composition.

Choose based on the content and how your audience is likely to consume it.

LinkedIn users often call swipeable document posts “carousels.”

These are commonly created by designing a series of pages, exporting them as a PDF, and uploading that PDF as a document.

Suggested LinkedIn carousel dimensions

Two practical design options are:

These measurements refer to the design proportions of individual slides. LinkedIn does not require every PDF page to have one of these exact pixel dimensions.

LinkedIn document upload limits

LinkedIn allows supported documents up to:

• 100 MB in file size
• 300 pages maximum

Only one document can be added to a single document post. PDF is a practical choice when you want to preserve your slide layout, fonts, and imagery.

Example: Creating a five-page LinkedIn carousel

Imagine you are publishing a guide called “Five Common LinkedIn Formatting Mistakes.” You could organize the document as follows:

• Slide 1: Five LinkedIn Formatting Mistakes (Catchy Title Slide)
• Slide 2: Writing an opening that takes too long to reach the point
• Slide 3: Using paragraphs that are difficult to scan
• Slide 4: Copying text without checking its formatting
• Slide 5: A simple checklist to review before publishing (Call-to-Action Slide)

Each slide has one clear purpose. That is more useful than filling every page with several unrelated ideas.

LinkedIn posts and LinkedIn articles serve different purposes.

A regular LinkedIn post appears directly in the feed and is limited to 3,000 characters.

A LinkedIn article uses a separate publishing editor and allows much longer content. LinkedIn documents an article limit of 125,000 characters.

Use a regular post for concise updates, professional experiences, timely questions, and everyday network conversations.

Consider a LinkedIn article when you need detailed explanations, multiple sections, comprehensive case studies, or a long-form professional guide.

If your text exceeds the standard post limit, publishing it as an article may be more appropriate than removing essential information simply to fit it into a feed update.

Have you ever copied a carefully formatted paragraph from Word, ChatGPT, or another writing application into LinkedIn, only to discover that the bold headings or bullet points no longer look the same?

This happens because LinkedIn's regular post editor does not handle rich-text formatting in the same way as a dedicated document editor.

For example, Markdown symbols do not automatically create bold headings in a regular LinkedIn feed post. A line written as:

may not retain its original rich-text styling when copied from every source.

Some formatting tools use special Unicode characters to create bold-looking or italic-looking text. These characters can be copied and pasted into LinkedIn, although their appearance and accessibility can differ across devices and assistive technologies.

A simple formatting workflow

1. Step 1: Write your message — Focus on communicating the idea before thinking about its visual appearance.
2. Step 2: Check its length — Make sure your text fits within LinkedIn's 3,000-character limit.
3. Step 3: Improve paragraph spacing — Separate major ideas with single empty lines so the text is easier to scan.
4. Step 4: Format important phrases selectively — Use emphasis only when it helps readers understand the structure.
5. Step 5: Preview and publish — Check the final result inside LinkedIn before posting.
