> **What aspect ratios does LinkedIn use in 2026?**
>
> LinkedIn uses **4:5 portrait (1080×1350 px)** for feed posts and document carousels, and **9:16 vertical (1080×1920 px)** for short-form video, with **1:1 (1080×1080 px)** for cross-platform assets. Its 2024 vertical video feed made 9:16 a first-class, lightly-contested format.

This guide covers every LinkedIn aspect ratio, image size and video dimension across feed, video, documents, banners and ads, verified against LinkedIn's current 2026 specs.

LinkedIn rolled out a dedicated vertical video feed through 2024, and that single change shifted its recommended aspect ratios more than anything in the previous five years. 9:16 is no longer "TikTok-only" content on LinkedIn; it is a first-class format with its own placement, its own analytics surface and a meaningful organic boost. At the same time, 4:5 portrait became the recommended feed ratio for static images and document posts. If your LinkedIn aspect ratios have not been updated since 2023, you are probably leaving reach on the table.

## The LinkedIn Aspect Ratio Cheat Sheet

| Format | Aspect Ratio | Recommended Pixels |
|--------|--------------|--------------------|
| Feed (portrait) | 4:5 | 1080×1350 |
| Feed (square) | 1:1 | 1200×1200 |
| Feed (landscape) | 1.91:1 | 1200×627 |
| Feed video (landscape) | 16:9 | 1920×1080 |
| Feed video (square) | 1:1 | 1080×1080 |
| Vertical video | 9:16 | 1080×1920 |
| Document carousel | 4:5 or 1:1 | 1080×1350 / 1080×1080 |
| Profile photo | 1:1 | 400×400 |
| Personal background banner | 4:1 | 1584×396 |
| Company logo | 1:1 | 300×300 |
| Company page banner | ~5.9:1 | 1128×191 |
| Hero image (Life tab) | 3:1 | 1128×376 |
| Single image ad | 1.91:1, 1:1, 4:5 | 1200×628 / 1200×1200 / 1080×1350 |
| Video ad | 16:9, 1:1, 4:5, 9:16 | varies |
| Carousel ad | 1:1 | 1080×1080 |
| Message ad banner | 300×250 | desktop only |

**The 2026 default:** 4:5 portrait (1080×1350) for static and document posts, and 9:16 vertical (1080×1920) for short-form video. Keep banner artwork distinct for personal (4:1) versus company (~6:1), because they are different aspect ratios.

## LinkedIn Feed Post Dimensions and Aspect Ratios

LinkedIn now ranks portrait content higher than square or landscape on the mobile feed, the same pattern as Instagram and Facebook. LinkedIn accepts uploaded photos from 3:1 (wide) up to 4:5 (tall).

### 4:5 portrait (1080×1350): recommended

The recommended ratio for static images and document carousels in 2026. Portrait images take up roughly 25% more vertical screen space on mobile than square, which matters because most LinkedIn engagement happens on mobile.

### 1:1 square (1200×1200)

Works on desktop and mobile equally. Best for assets that need to render cleanly across devices without aspect-ratio surprises. Slightly lower mobile engagement than 4:5.

### 1.91:1 landscape (1200×627)

The classic LinkedIn link-share ratio. Useful for Open Graph cards, blog post promotions and external article shares. For pure feed engagement on mobile, 4:5 outperforms.

### File specs

- Format: JPG, PNG, GIF
- Recommended minimum: 1080 px wide (552×276 absolute minimum)
- Max file size: 5 MB for feed images; LinkedIn caps Page images at around 3 MB

---

## LinkedIn Vertical Video (9:16)

This is the biggest LinkedIn change in years. LinkedIn rolled out a dedicated vertical video feed on mobile through 2024 and expanded its video tools, analytics and search in February 2025. The platform reported **video uploads up 36% year over year, viewership up 36%, and video creation on the platform up 100%** ([TechCrunch](https://techcrunch.com/2025/02/04/linkedin-amps-up-vertical-video-tools-as-uploads-jump-36/)).

### Spec summary

- **Aspect ratio:** 9:16
- **Recommended pixels:** 1080×1920
- **Length:** 3 seconds to 10 minutes (under 60 seconds recommended for the vertical feed)
- **Frame rate:** 30 fps
- **Codec:** H.264 video, AAC audio
- **File:** MP4, up to 5 GB natively, though keeping vertical clips under ~500 MB uploads faster

### Where it lives

The vertical video tab is mobile-first. On desktop, vertical videos still appear in the organic feed but with letterboxing. As paid creative, vertical assets only deliver to mobile placements.

### Why this matters for B2B creators

LinkedIn vertical video is far less competitive than TikTok or Reels for the same content. Many B2B niches have very few vertical creators on LinkedIn, which means the same 30-second clip you would struggle to grow with on TikTok can earn serious reach on LinkedIn. The format mismatch is the opportunity, and it is the easiest [cross-posting](/cross-posting) win in B2B.

---

## LinkedIn Video Dimensions (Standard Feed Video)

For traditional landscape or square video posts, not the dedicated vertical feed:

| Orientation | Aspect Ratio | Recommended Pixels |
|-------------|--------------|--------------------|
| Landscape | 16:9 | 1920×1080 |
| Square | 1:1 | 1080×1080 |
| Portrait | 4:5 | 1080×1350 |
| Vertical | 9:16 | 1080×1920 |

**Length:** 3 seconds to 10 minutes on mobile (up to 15 minutes from desktop). **File:** MP4 or MOV, up to 5 GB, with under 200 MB recommended for fast processing.

**Safe zone:** keep captions and key text in the centre 1080×1080 region so the same asset renders cleanly on the desktop 16:9 preview and the mobile vertical tab.

---

## LinkedIn Carousel Size (Document Posts and PDF Carousels)

LinkedIn's document carousels, uploaded as PDFs, are one of the highest-engagement organic formats on the platform. They are often cited at roughly triple the engagement of a standard image post.

### Spec summary

- **Recommended ratio:** 4:5 portrait (1080×1350) for highest mobile engagement
- **Common alternative:** 1:1 square (1080×1080), which native carousel ads also use
- **Also accepted:** 16:9 landscape (1920×1080)
- **File:** PDF preferred; PPTX and DOC or DOCX also supported
- **Max file size:** 100 MB
- **Max pages:** 300
- **Optimal slide count:** 8 to 15 (drop-off after slide 10)

**The data:** 4:5 portrait carousels consistently outperform 1:1 square because they occupy roughly 25% more vertical space on mobile, where most swipes happen. If you are producing document carousels, default to 1080×1350.

LinkedIn renders a small "swipe" indicator overlay on slide 1, so avoid thin text near the bottom edge of your cover slide. The [LinkedIn carousel maker](/tools/linkedin-carousel-maker) outputs slides at the right 4:5 dimensions.

## Profile Photo and Personal Banner

### Personal profile photo

- **Aspect ratio:** 1:1 (cropped to a circle)
- **Recommended:** 400×400 px
- **Accepted:** 200×200 to 20,000×20,000
- **File:** JPG or PNG, up to 8 MB
- **Pitfall:** displayed as a circle, so keep the face centred; logos with square corners get clipped

### Personal background banner

- **Dimensions:** 1584×396 px (4:1 aspect ratio)
- **Safe zone:** centre 1200×300 px
- **Pitfall:** the profile photo overlays the lower-left corner (roughly 568×264 px on desktop, top-centre on mobile), so keep text to the right or upper-right

---

## LinkedIn Banner Size (Company Page Assets)

LinkedIn company pages have different banner dimensions from personal profiles, so do not reuse artwork between them.

### Company page logo
- **Recommended:** 300×300 px (1:1)
- **Minimum:** 300×300
- **Max file size:** 4 MB
- **Format:** PNG with transparency preferred

### Company page banner (cover image)
- **Dimensions:** 1128×191 px (~5.9:1)
- **File:** JPG, PNG or GIF, up to 8 MB
- **Pitfall:** a much wider and thinner ratio than the personal banner (4:1), so do not reuse personal banner artwork
- **2026 status:** no change; 1128×191 has been standard since 2020 and remains current

### Hero image (Life tab)
- **Dimensions:** 1128×376 px (3:1)
- **File:** JPG or PNG, up to 8 MB
- **Optional larger modules:** 1536×768

LinkedIn ads support multi-ratio creative, so ship a kit rather than a single asset.

### Single image ad

| Aspect Ratio | Recommended Pixels | Placement |
|--------------|--------------------|-----------|
| 1.91:1 horizontal | 1200×628 | Desktop + mobile |
| 1:1 square | 1200×1200 | Desktop + mobile |
| 4:5 vertical | 1080×1350 | Mobile-first (recommended to avoid borders) |
| 1:1.91 vertical | 628×1200 | Mobile only |

- **Length:** 3 seconds to 30 minutes (15 to 30 seconds performs best for awareness)
- **File:** up to 200 MB
- **Vertical only delivers to mobile**

### Carousel ad

- **Aspect ratio:** 1:1 cards at 1080×1080

## What Changed for LinkedIn in 2024 to 2026

**1. Dedicated vertical video feed rolled out.** Through 2024, with video tools and analytics expanded in February 2025. 9:16 vertical (1080×1920) is now a first-class format.

**2. 4:5 portrait became the recommended feed ratio.** Mobile engagement data drove the shift away from 1:1 square.

**3. Document and carousel engagement boom.** Document posts now report among the highest engagement of any organic format, with 4:5 portrait leading the way.

**4. LinkedIn Stories did NOT return.** Despite rumours, classic Stories were retired in September 2021 and have not come back. The "Stories return" chatter all refers to the vertical video feed.

**5. Video creation up sharply.** LinkedIn reported video creation on the platform up 100% year over year, making it a meaningful video platform for B2B creators, and the algorithm rewards consistent video posting.

---

## Common LinkedIn Aspect Ratio Mistakes

1. **Reusing the personal banner (1584×396, 4:1) as a company banner (1128×191, ~6:1).** Different ratios. Resize each separately.

2. **Designing document carousels at 1:1 because "LinkedIn is professional."** 4:5 portrait engagement is materially higher. Switch the default.

3. **Posting 16:9 landscape video to the vertical feed.** It letterboxes badly. The vertical feed is a 9:16-only surface.

4. **Burning critical text into the bottom of vertical video.** Caption tools and engagement icons overlay this zone, the same pattern as TikTok and Reels.

5. **Ignoring the vertical video feed entirely.** Many B2B niches have low competition here. The format mismatch is the opportunity.

6. **Defaulting every post to square 1:1.** Square works but underperforms 4:5 on mobile. If you are optimising for engagement, default to 4:5.

7. **Logos in the lower-left of the personal banner.** The profile photo overlays this corner on desktop. Move logos right or up.

8. **Using stock photo dimensions (3:2 or 16:9) for feed posts.** Resize to 4:5 before posting. The [image resizer](/tools/image-resizer) handles this.

## LinkedIn File Sizes, Formats & Upload Limits

Ratios tell you how an asset is framed; file specs decide whether it uploads cleanly and renders sharp. Here is every LinkedIn format with its max file size and accepted formats in one place.

| Format | Dimensions (px) | Max File Size | Accepted Formats |
|--------|-----------------|---------------|------------------|
| Feed post image | 1080×1350 / 1080×1080 / 1200×627 | 5 MB | JPG, PNG, GIF |
| Document carousel | 1080×1350 or 1080×1080 | 100 MB total PDF | PDF (PPTX, DOC/DOCX also supported) |
| Article cover image | 1200×644 | 10 MB | JPG, PNG |
| Feed video | up to 1920×1080 / 1080×1920 | 5 GB | MP4, MOV, AVI, FLV, MKV, WebM |
| Profile photo | 400×400 | 8 MB | JPG, PNG |
| Personal banner | 1584×396 | 8 MB | JPG, PNG |
| Company logo | 300×300 | 4 MB | PNG (transparency preferred) |
| Company page banner | 1128×191 | 8 MB | JPG, PNG, GIF |
| Single image ad | 1200×628 / 1200×1200 / 1080×1350 | 5 MB | JPG, PNG, GIF |
| Carousel ad | 1080×1080 per card | 10 MB per card | JPG, PNG |
| Video ad | 1920×1080 / 1080×1920 | 200 MB | MP4 |
| Message ad banner | 300×250 | 2 MB | JPG, PNG, GIF (non-animated) |
| Dynamic ad logo | 100×100 | n/a | JPG, PNG |
| Dynamic ad background | 300×250 | n/a | JPG, PNG |

### Article cover image

LinkedIn's native articles take a **1200×644 px (1.91:1)** cover image, up to 10 MB, in JPG or PNG. The cover shows both at the top of the article and in the feed when the article is shared. If you skip it, LinkedIn pulls a random image from the article body, which rarely looks intentional. Keep key text and visuals in the centre 1000×500 px area to allow for slight cropping across devices.

### Video technical specs

For feed video, LinkedIn accepts MP4, MOV, AVI, FLV, MKV and WebM, but **MP4 with H.264 video and AAC audio** is the safest choice and takes the least compression. Minimum resolution is 256×144 and maximum is 4096×2304. Frame rates from 10 to 60 fps are supported, with 30 fps the standard, and bit rates range from 192 Kbps to 30 Mbps.

### Dynamic ads

Dynamic ads pull the viewer's profile photo automatically, so your creative only needs a **100×100 px company logo** and an optional **300×250 px background image**, both JPG or PNG.

### File quality tips

- **Match the recommended dimensions exactly.** Uploading oversized images forces LinkedIn to downscale, which adds compression. Resize before you post.
- **Use PNG for text-heavy graphics.** Screenshots, data charts and quote images stay crisp as PNG; use JPG at 90 to 95% quality for photographs.
- **Keep images under 3 MB where possible.** The organic limit is 5 MB, but smaller files upload faster and display more reliably on slow connections.
- **Export in sRGB colour space.** LinkedIn strips other colour profiles, which can shift your colours. sRGB keeps what you see matching what gets displayed.
- **Keep carousel slides a single size.** Mixed dimensions inside one PDF create an uneven, unprofessional viewing experience.
- **Test on desktop and mobile.** LinkedIn's layout varies significantly between devices; a banner that looks perfect on desktop can crop poorly on a phone.

## Frequently Asked Questions

### What is the best LinkedIn aspect ratio in 2026?

4:5 portrait (1080×1350 px) for feed posts and document carousels, and 9:16 vertical (1080×1920 px) for short-form video. These two ratios fit LinkedIn's mobile-first algorithm and the new vertical video feed launched in 2024.

### What's the LinkedIn vertical video aspect ratio?

9:16 (1080×1920 px), MP4 H.264, 30 fps, 3 seconds to 10 minutes (under 60 seconds recommended for the vertical feed), max 500 MB. LinkedIn rolled out the dedicated vertical video tab in late 2024 with expanded analytics in February 2025.

### Has LinkedIn brought back Stories?

No. Classic LinkedIn Stories were retired in September 2021 and have not returned. The "Stories return" rumours all refer to the new vertical video feed, which is full posts, not 24-hour ephemeral Stories. Vertical video is the modern replacement.

### What's the LinkedIn document carousel aspect ratio?

4:5 portrait (1080×1350 px) for highest engagement. LinkedIn also accepts 1:1 square and 16:9 landscape, but 4:5 occupies ~25% more vertical screen space on mobile and consistently outperforms in engagement metrics. Document carousels overall report ~3× the engagement of standard image posts.

### What's the LinkedIn company page banner size?

1128×191 px (~5.9:1 aspect ratio), JPG/PNG/GIF, up to 8 MB. This is different from the personal background banner (1584×396, 4:1), don't reuse artwork. Both spec sizes have been stable since 2020 with no recent changes.

### What's the LinkedIn personal profile photo size?

400×400 px (1:1 square, displayed as circle), JPG/PNG up to 8 MB. The accepted range is 200×200 to 20,000×20,000, but 400×400 is the recommended sweet spot for sharp rendering across desktop and mobile.

### Should I post vertical video on LinkedIn?

Yes, especially for B2B creators. LinkedIn's dedicated vertical video feed (launched late 2024) is dramatically less competitive than TikTok or Reels for similar content. Many B2B niches have few vertical creators on LinkedIn, which makes the format mismatch a real growth opportunity.

### Can I cross-post my Reels or TikToks to LinkedIn?

Yes, that's the cross-posting case. Export at 1080×1920 (9:16) and the same asset works natively on LinkedIn's vertical video tab. Keep the bottom 250–340 px clear (caption zones differ by platform) and the right edge ~120 px clear (engagement icons).
