LinkedIn Post Dimensions: Size Guide & Cheatsheet (2026)

Nothing kills a brilliant LinkedIn post faster than a horribly cropped preview image. You spent hours refining the copy, crafting the hooks, and organizing your insights, only for the platform to chop off half your graphic or shrink your text into an unreadable thumbnail.

Getting your dimensions right is the difference between an asset that stops the thumb and one people scroll past without a second glance. Whether you are building organic authority, setting up a document carousel, or running an ad campaign, here is your complete guide to LinkedIn post dimensions.

1. Single Image Posts

When uploading a standard image directly to the LinkedIn feed, you have three primary choices depending on how much vertical screen real estate you want to claim.

| Format | Dimensions (Pixels) | Aspect Ratio | Best For |
| :— | :— | :— | :— |
| Landscape | $1200 times 627$ | $1.91:1$ | Link previews, photography, horizontal charts |
| Square | $1080 times 1080$ | $1:1$ | Balanced look across desktop and mobile |
| Portrait | $1080 times 1350$ | $4:5$ | Infographics, maximum mobile feed dominance |

• Pro Tip: Keep file sizes under 5MB, and use PNG for text-heavy graphics or JPEG for high-resolution photography.

2. Document Carousels (PDF Uploads)

LinkedIn carousels (created by uploading a multi-page PDF via the document icon) remain one of the most powerful formats for generating saves and deep engagement.

• Recommended Size: $1080 times 1350text{ px}$ ($4:5$ portrait) to capture maximum screen space on mobile devices. Alternatively, use $1080 times 1080text{ px}$ ($1:1$ square) for a uniform aesthetic.
• Crucial Rule: Keep all slides in the exact same aspect ratio. If even one slide has different dimensions, LinkedIn will force an awkward crop across the entire deck.
• Safe Zones: Leave a 10% margin (roughly 100 pixels) around the edges of your slides. Critical text placed directly on the border risks getting clipped by UI elements or responsive scaling.

3. Native Video Specs

Video content on LinkedIn has evolved, and vertical formats are taking the lead as mobile consumption dominates.

• Vertical (Recommended): $1080 times 1920text{ px}$ ($9:16$ ratio)
• Square: $1080 times 1080text{ px}$ ($1:1$ ratio)
• Landscape: $1920 times 1080text{ px}$ ($16:9$ ratio)
• Technical Limits: Organic videos can run up to 10 minutes with a maximum file size of 5 GB. Stick to MP4 formats with crisp 1080p resolution for smooth playback.

4. Profile and Banner Assets

Your personal profile or company page is your landing page. Make sure your branding elements fit their designated frames without distortion:

• Personal Profile Photo: $400 times 400text{ px}$ minimum ($1:1$)
• Personal Background Banner: $1584 times 396text{ px}$ ($4:1$)
• Company Page Logo: $400 times 400text{ px}$
• Company Page Cover Image: $1512 times 256text{ px}$

Summary Checklist for Designers

1. Design mobile-first: With over 60% of LinkedIn users browsing on phones, portrait layouts ($4:5$ for images/carousels and $9:16$ for video) win the battle for attention.
2. Double-check link previews: If you are sharing an external link, customize your Open Graph (OG) image to match the $1200 times 627text{ px}$ landscape standard so it renders cleanly.
3. Export properly: Always export your visuals in RGB color mode to ensure colors match what you designed on your monitor.
