LinkedIn Aspect Ratios: Image & Video Sizes for Posts, Profiles & Ads
Updated March 2026
LinkedIn is the one social platform where looking polished actually matters for your career. A blurry profile picture, a stretched banner image, or a video that gets cropped in the middle of your face - those things make a worse impression on LinkedIn than they would on Instagram or Twitter because the audience is paying closer attention to professionalism.
The tricky part is that LinkedIn's image requirements are different from every other platform. The banner ratio is unique, the feed handles images its own way, and the ad formats have specific constraints you won't find elsewhere. This guide covers every image and video dimension on LinkedIn so you can get it right the first time.
Quick Reference: LinkedIn Dimensions
| Placement | Aspect Ratio | Resolution | Notes |
|---|---|---|---|
| Feed Image (Landscape) | 1.91:1 | 1200 × 627 | Standard share image |
| Feed Image (Square) | 1:1 | 1080 × 1080 | More engagement than landscape |
| Feed Image (Portrait) | 4:5 | 1080 × 1350 | Maximum feed real estate |
| Profile Photo | 1:1 | 400 × 400 | Cropped to circle |
| Profile Banner | ~4:1 | 1584 × 396 | Personal profile |
| Company Cover | ~5.9:1 | 1128 × 191 | Company/org page |
| Video Post | 1:1 or 16:9 | 1080 × 1080 or 1920 × 1080 | Up to 10 min |
| Carousel Post | 1:1 or 1.91:1 | 1080 × 1080 or 1200 × 627 | PDF upload, up to 300 pages |
| Article Cover Image | 1.91:1 | 1200 × 627 | LinkedIn Articles hero image |
Feed Post Images
LinkedIn's feed supports three main image orientations. Unlike Instagram where portrait images dominate, LinkedIn's algorithm doesn't strongly favor any particular ratio. But the amount of screen space your post occupies does affect engagement, and taller images take up more space in the scroll.
Square images take up a good amount of real estate in the feed without looking like you're trying too hard to game the algorithm. They also work if you repurpose the same image on Instagram or Facebook.
Portrait images fill the most screen space on mobile. On desktop, they're still prominent but LinkedIn may add a "click to see full image" button for very tall images. The 4:5 ratio is the sweet spot before that happens.
This is what LinkedIn auto-generates when you share a link. It's fine for link shares, but for image-only posts, you lose vertical space compared to square or portrait. Use it when the content naturally suits a wide format - data charts, team photos, or product screenshots.
LinkedIn accepts JPEG, PNG, and GIF (static only - animated GIFs play on some clients but not reliably). Maximum file size is 10 MB for images. If you're uploading multiple images to a single post, LinkedIn allows up to 9 images and will arrange them in a grid.
Profile Photos
Your LinkedIn profile photo uses a 1:1 square aspect ratio and gets cropped into a circle. The recommended minimum is 400 × 400 pixels, though LinkedIn accepts images up to 8000 × 8000 pixels and 8 MB.
LinkedIn displays your profile picture at different sizes depending on context. On your own profile page it's large - about 200px across. In the feed next to your posts, it's around 48px. In comment threads, it shrinks to about 36px. So your photo needs to be recognizable as a small circle.
- Headshot from the shoulders up - fill the frame with your face
- Simple, uncluttered background (solid color or soft blur)
- Good lighting on your face - no heavy shadows
- Professional but approachable expression
- Keep the circular crop in mind - your face should be centered
LinkedIn data shows that profiles with a photo get up to 21 times more views than those without one. And recruiters are significantly more likely to engage with profiles that have clear, professional headshots rather than casual photos, group shots, or logos.
Banner Images (Profile & Company)
LinkedIn has two different banner image slots, and they use different dimensions. Getting them mixed up means your carefully designed banner will get cropped awkwardly.
Roughly a 4:1 aspect ratio. This sits behind your profile photo and headline at the top of your personal profile. On mobile, the left third gets covered by your profile picture, so put important text or graphics on the right side.
Max file size: 8 MB | Formats: JPG, PNG
Much narrower than the personal banner at about 5.9:1. Company logos overlay the bottom-left corner. This is a tricky canvas to work with because it's so thin - keep designs simple and horizontal.
Max file size: 4 MB | Formats: JPG, PNG
A common mistake is designing a beautiful banner at the personal profile dimensions and then uploading it to a company page (or vice versa). They look completely different, so design separately for each. And always check how the banner looks on mobile - the crop is noticeably different from desktop.
LinkedIn Video
LinkedIn video has grown significantly and the platform's algorithm tends to favor native video over link shares to YouTube. The platform supports aspect ratios from 1:2.4 to 2.4:1, giving you plenty of flexibility.
Min 256 × 144, max 4096 × 2304
1080p is the practical ceiling. Uploading 4K works but LinkedIn compresses it down anyway. Stick to 1920 × 1080 for landscape or 1080 × 1080 for square.
H.264 (MP4)
MP4 with H.264 video and AAC audio. LinkedIn also accepts ASF, AVI, FLV, MOV, and WebM, but MP4 is the most reliable.
3 seconds to 10 minutes
Company pages can upload videos up to 10 minutes. LinkedIn Live streams have no practical limit. Short videos (30-90 seconds) tend to perform best for engagement.
Max 5 GB
Generous limit, but smaller files upload faster and start processing sooner. Aim for under 200 MB for a typical 1-2 minute video at 1080p.
Square video (1:1) tends to outperform landscape on LinkedIn because it occupies more vertical space in the mobile feed. Vertical video (9:16) works too, though LinkedIn's feed isn't optimized for vertical content the way TikTok or Instagram Reels are.
LinkedIn auto-plays videos on mute in the feed, so add captions or text overlays. The platform now offers auto-captioning, but it's not always accurate - review and edit the generated captions before publishing, especially for industry-specific terminology.
Carousel Posts (Document Uploads)
LinkedIn carousels are one of the platform's highest-engagement formats. They're technically PDF uploads that display as swipeable slide decks in the feed. You can upload PDFs, PowerPoint files, or Word documents with up to 300 pages.
Design your slides at 1080 × 1080 pixels. Square carousels look great on mobile and desktop. Most LinkedIn carousel creators use this format because it maximizes the viewable area in the feed.
1080 × 1350 pixels. Takes up even more screen space than square, though it looks slightly less conventional. Works well for step-by-step instructions and listicles.
Standard presentation aspect ratio. If you're repurposing an existing PowerPoint deck, this is what you'll get. It works but takes up less feed space than square or portrait formats.
LinkedIn carousel posts typically get 1.5 to 3 times more engagement than standard image posts. Keep each slide focused on one idea with large text (at least 24pt equivalent). People swipe quickly, so make each page scannable in a few seconds. Max file size is 100 MB for document uploads.
LinkedIn Articles & Newsletters
LinkedIn Articles (long-form blog posts published on the platform) and Newsletters use a cover image at the top. The ideal size is 1200 × 627 pixels (1.91:1 landscape), which is the same ratio LinkedIn uses for link share previews.
When someone shares your article in their feed, the cover image becomes the preview thumbnail. A strong cover image can be the difference between someone clicking through or scrolling past.
- Cover image: 1200 × 627 px (1.91:1)
- In-article images: up to 1300px wide, any height
- Max file size: 10 MB per image
- Formats: JPG, PNG, GIF (static)
For in-article images, there's no fixed aspect ratio constraint. LinkedIn will scale them to fit the article column width (about 700px on desktop). But if you're including charts, infographics, or diagrams, design them at 1300px wide for the sharpest display.
LinkedIn Ad Dimensions
LinkedIn's ad platform has some of the most specific image requirements of any social network. Using the wrong dimensions won't just look bad - your ad may get rejected during review.
| Ad Format | Aspect Ratio | Resolution | Notes |
|---|---|---|---|
| Sponsored Content (Image) | 1.91:1 or 1:1 | 1200 × 627 or 1080² | In-feed ads |
| Sponsored Content (Video) | 16:9 or 1:1 | 1920 × 1080 or 1080² | Up to 30 min for ads |
| Carousel Ad | 1:1 | 1080 × 1080 | 2-10 cards |
| Message Ad (InMail) | ~2.6:1 | 300 × 250 | Banner in sponsored messages |
| Dynamic Ad | 1:1 | 100 × 100 min | Personalized sidebar ads |
| Event Image | 16:9 | 1920 × 1080 | LinkedIn Events cover |
For sponsored content (the most common LinkedIn ad type), 1:1 square images at 1080 × 1080 tend to outperform 1.91:1 landscape because they take up more feed space. LinkedIn's own marketing team has confirmed that square images drive higher engagement rates in their Campaign Manager best practices.
Events, Groups & Other Formats
Beyond posts and ads, LinkedIn has several other places where images show up. Here are the ones that catch people off guard most often:
Event cover images use 16:9 at 1920 × 1080. This is the same ratio used for YouTube thumbnails, so you can repurpose event graphics between platforms. The bottom portion gets partially covered by the event title, so keep important visuals in the top two-thirds.
Group cover images are 1536 × 768 pixels. The group logo displays at 60 × 60 as a 1:1 square. These are low-priority assets since LinkedIn Groups don't get much visibility anymore, but if you admin a group, at least set them so the page looks complete.
Company page logos should be 300 × 300 pixels (1:1 square). This appears next to your company's posts in the feed and on the company page itself. Keep it simple - just the logo mark, no tagline or extra text.
LinkedIn vs Other Platforms
If you're managing content across multiple networks, here's how LinkedIn stacks up against the other major platforms:
| Content Type | Twitter/X | ||
|---|---|---|---|
| Feed Image | 1:1 (1080×1080) | 16:9 (1600×900) | 4:5 (1080×1350) |
| Video | 1:1 or 16:9 | 16:9 (1920×1080) | 9:16 (1080×1920) |
| Banner | 4:1 (1584×396) | 3:1 (1500×500) | N/A |
| Profile | 1:1 (400×400) | 1:1 (400×400) | 1:1 (320×320+) |
The biggest difference: LinkedIn favors square (1:1) content for feed posts, while Twitter leans landscape (16:9) and Instagram leans portrait (4:5). If you need one image that works on all three, 1:1 square is your best bet - it's optimal for LinkedIn and acceptable on the other two.
Frequently Asked Questions
What is the best image size for LinkedIn posts?
For single-image LinkedIn posts, 1200 × 627 pixels (1.91:1 landscape) or 1080 × 1080 pixels (1:1 square) work best. Square images tend to get more engagement because they take up more vertical space in the feed. LinkedIn also supports portrait images at 1080 × 1350 (4:5), which fill even more screen real estate on mobile.
What size is a LinkedIn profile picture?
LinkedIn profile photos should be 400 × 400 pixels minimum, using a 1:1 square aspect ratio. The platform crops it into a circle. Upload at least 400 × 400 for clear display, though LinkedIn accepts up to 8 MB and 8000 × 8000. Keep your face centered since it appears as small as 36px in comment threads.
What are the LinkedIn banner dimensions?
LinkedIn personal profile banners should be 1584 × 396 pixels, which is roughly a 4:1 aspect ratio. Company page cover images are slightly different at 1128 × 191 pixels (about 5.9:1). Both get cropped differently on mobile versus desktop, so keep important content centered.
What aspect ratio should LinkedIn videos be?
LinkedIn supports video aspect ratios from 1:2.4 to 2.4:1. The most effective formats are 1:1 square (1080 × 1080) for maximum feed visibility, 9:16 vertical (1080 × 1920) which fills mobile screens, and 16:9 landscape (1920 × 1080) for professional presentations. Videos can be up to 10 minutes long for regular posts.
