Detailed LinkedIn Post Dimensions by Format
Below you'll find specific guidance for every LinkedIn image format — recommended pixel dimensions, file size limits, pro tips, and what goes wrong when you use the wrong size.
Profile Photo
Dimensions
400 × 400 px (minimum)
Aspect Ratio
1 : 1 (square)
Max Size
8 MB
File Types
JPG, PNG, GIF
💡 Tips
- Upload at least 400 × 400 px — LinkedIn will crop it into a circle.
- Use a clear headshot with a simple background for maximum recognition in the feed.
- Avoid logos or text — they become unreadable at thumbnail size.
⚠️ What happens with wrong dimensions?
LinkedIn crops non-square images from the center, which may cut off your face or key elements. Low-resolution photos appear blurry on desktop.
Cover / Banner Image
Dimensions
1584 × 396 px
Aspect Ratio
4 : 1
Max Size
8 MB
File Types
JPG, PNG
💡 Tips
- Keep key information (text, logos) in the center — mobile crops about 30 % from each side.
- Use this space for branding, a tagline, or a subtle call-to-action.
- Design at 2× (3168 × 792 px) for Retina displays, then export at 1584 × 396.
⚠️ What happens with wrong dimensions?
Too-narrow images get stretched, creating a pixelated look. On mobile, the left and right edges are cropped, potentially hiding important details.
Feed Post Image — Landscape
Dimensions
1200 × 627 px (recommended)
Aspect Ratio
1.91 : 1
Max Size
10 MB
File Types
JPG, PNG, GIF
💡 Tips
- This is LinkedIn's default aspect ratio for link previews and single-image posts.
- Use high-contrast text overlays sparingly — the feed is already text-heavy.
- Always include alt text for accessibility and SEO.
⚠️ What happens with wrong dimensions?
Images that aren't 1.91 : 1 will be letterboxed with white bars, reducing visual impact and taking up less feed space.
Feed Post Image — Square
Dimensions
1080 × 1080 px
Aspect Ratio
1 : 1
Max Size
10 MB
File Types
JPG, PNG, GIF
💡 Tips
- Square images take up more vertical feed space than landscape, stopping the scroll.
- Great for infographics, data visualizations, and quotes.
- If posting multiple images, keep them all the same aspect ratio for a clean gallery.
⚠️ What happens with wrong dimensions?
Non-square uploads in a square frame will be auto-cropped. Key information at edges may be cut off.
Feed Post Image — Portrait
Dimensions
1080 × 1350 px
Aspect Ratio
4 : 5
Max Size
10 MB
File Types
JPG, PNG, GIF
💡 Tips
- Portrait images take up the most feed real estate — excellent for engagement.
- LinkedIn supports up to 4 : 5 ratio. Anything taller (like 9 : 16) gets cropped.
- Ideal for tall infographics, step-by-step visuals, and comparison charts.
⚠️ What happens with wrong dimensions?
Images taller than 4 : 5 are cropped from the bottom. Critical info at the bottom of tall images will be hidden.
Carousel / Document Posts
Dimensions
1080 × 1080 px or 1920 × 1080 px
Aspect Ratio
1 : 1 or 16 : 9
Max Size
100 MB (PDF), up to 300 pages
File Types
PDF, PPT, PPTX, DOC, DOCX
💡 Tips
- Upload as PDF for the best quality — PowerPoint conversions can lose formatting.
- Square (1080 × 1080) works best on mobile; landscape (1920 × 1080) is better for desktop-heavy audiences.
- LinkedIn carousels consistently get 2-3× the engagement of single-image posts.
⚠️ What happens with wrong dimensions?
Non-standard sizes render unpredictably. Text may appear too small on mobile or get cut off at page edges.
Video Posts
Dimensions
1920 × 1080 px (landscape) or 1080 × 1920 px (portrait)
Aspect Ratio
16 : 9 (landscape) or 9 : 16 (portrait)
Max Size
5 GB, 3 seconds – 10 minutes recommended
File Types
MP4 (recommended), ASF, AVI, FLV, MKV, MOV, WebM
💡 Tips
- LinkedIn auto-plays videos on mute — always add captions or burned-in subtitles.
- The first 3 seconds are critical. Start with a hook, not a logo intro.
- Keep videos under 90 seconds for the highest completion rates.
⚠️ What happens with wrong dimensions?
Videos over 5 GB fail to upload. Non-standard aspect ratios get letterboxed with black bars, looking unprofessional in the feed.
Article Cover Image
Dimensions
1200 × 644 px
Aspect Ratio
1.86 : 1
Max Size
10 MB
File Types
JPG, PNG
💡 Tips
- This is the hero image for LinkedIn articles (long-form blog posts).
- Keep text minimal — the article title overlays this image on mobile.
- Use an eye-catching visual that creates curiosity about the article content.
⚠️ What happens with wrong dimensions?
Wrong dimensions cause awkward cropping. The title overlay on mobile may clash with busy images, making both the image and title hard to read.
Company Page Logo
Dimensions
300 × 300 px
Aspect Ratio
1 : 1
Max Size
4 MB
File Types
PNG (recommended), JPG
💡 Tips
- Use a clean, recognizable logo — it appears tiny in search results and comments.
- PNG with transparent background works best for a professional look.
- This logo also appears on employee profiles under 'Experience.'
⚠️ What happens with wrong dimensions?
Non-square logos get distorted. Low-res logos look unprofessional when displayed alongside competitor company pages.
Company Page Banner
Dimensions
1128 × 191 px
Aspect Ratio
5.9 : 1
Max Size
4 MB
File Types
PNG, JPG
💡 Tips
- Use this space to communicate your value proposition or latest campaign.
- Keep text centered — mobile crops the sides significantly.
- Update it quarterly to keep the page looking fresh.
⚠️ What happens with wrong dimensions?
Oversized images are compressed and lose quality. Undersized images stretch and pixelate. Mobile crops up to 40 % from the sides.
LinkedIn Ad Image
Dimensions
1200 × 627 px
Aspect Ratio
1.91 : 1
Max Size
5 MB
File Types
JPG, PNG
💡 Tips
- Follow the same dimensions as organic feed images for a native feel.
- LinkedIn recommends keeping text to under 20 % of the image area.
- Use bold colors and clear CTAs — ads compete with organic content in the feed.
⚠️ What happens with wrong dimensions?
Non-standard ad images may be rejected or displayed with white bars. This wastes ad spend on low-impact placements.

Not all image sizes perform equally. Based on engagement data, here's how the main feed formats rank:

Takes up the most screen real estate. Ideal for infographics and step-by-step guides. Highest average engagement rate.
Carousel / Document (1080 × 1080)
Multi-page carousels drive high dwell time and saves. LinkedIn's algorithm rewards the swipe interaction.
Square (1080 × 1080)
A solid middle ground — larger than landscape, works well for single data points, quotes, and announcements.
