The Ultimate Guide to LinkedIn Post Dimensions

Nailing your visual dimensions on LinkedIn can mean the difference between a post that stops the scroll and one that gets instantly ignored. Because LinkedIn compresses, crops, and renders content differently across mobile screens and desktop monitors, using the exact, optimized pixel dimensions ensures your graphics, documents, and videos look crisp and professional.

This comprehensive guide breaks down the optimal dimensions and file specifications for every type of LinkedIn post.

1. Single Image Posts

Single images are the workhorse of the LinkedIn feed. Depending on the layout you want, you can choose from three main aspect ratios:

• Square ($1200 times 1200text{ px}$, $1:1$ ratio): Highly recommended for general feed posts, info-graphics, and quote graphics. It takes up a healthy amount of vertical space on both mobile and desktop screens.
• Vertical / Portrait ($1200 times 1500text{ px}$ or $1080 times 1350text{ px}$, $4:5$ ratio): Excellent for mobile-first storytelling. Vertical images dominate mobile screen real estate, pushing competing posts out of view.
• Landscape ($1200 times 627text{ px}$, $1.91:1$ ratio): Best used for link previews, press releases, or wide landscape photography.

Pro-Tip for Image Files: Keep your images under $5text{ MB}$. Save text-heavy graphics as PNG files to keep text sharp, and standard photos as JPEG. Always design in the sRGB color space.

2. Document Carousels (PDF Slides)

Document carousels are one of the highest-performing content formats on LinkedIn for organic reach and engagement. When you upload a multi-page PDF, LinkedIn renders it as a swipeable slide deck.

• Recommended Size: $1080 times 1350text{ px}$ ($4:5$ ratio) per page.
• Alternative Size: $1080 times 1080text{ px}$ ($1:1$ square ratio).
• Technical Limits: Maximum file size of $100text{ MB}$ and up to 300 pages (though 5 to 10 pages is the sweet spot for audience retention).
• Design Best Practices: Over 60% of LinkedIn consumption happens on mobile. Make sure your body text is at least 24pt so it remains legible on smaller smartphone screens.

3. Video Posts

Video content commands massive engagement, especially when optimized for how people naturally hold their phones.

• Vertical Video ($1080 times 1920text{ px}$, $9:16$ ratio): The top choice for high watch-through rates because it fills the entire mobile screen.
• Horizontal Widescreen ($1920 times 1080text{ px}$, $16:9$ ratio): Ideal for desktop-heavy enterprise content, webinar clips, and traditional landscape demos.
• Square Video ($1080 times 1080text{ px}$, $1:1$ ratio): A safe middle ground that looks balanced on both desktop feeds and mobile feeds.
• Technical Specs: Videos can range from 3 seconds to 10 minutes, with a maximum file size of $5text{ GB}$. Format files as MP4 or MOV.

4. Profile and Company Page Branding Assets

Don’t let blurry branding undermine your authority. Ensure your profile and company page graphics fit these exact parameters:

• Personal Profile Photo: $400 times 400text{ px}$ minimum ($1:1$ ratio; max $3text{ MB}$).
• Personal Background / Cover Banner: $1584 times 396text{ px}$ ($4:1$ ratio; max $8text{ MB}$).
• Company Page Logo: $400 times 400text{ px}$.
• Company Page Cover Image: $1128 times 191text{ px}$.

Summary Checklist Before You Publish

1. Double-check your aspect ratios: Stick to $1:1$ or $4:5$ for feed dominance.
2. Watch the margins: Keep crucial text and elements away from the absolute edges of your layout so they aren’t clipped by platform UI elements.
3. Preview on mobile: Always upload your asset or check it via a mobile device before hitting publish to ensure readability and formatting look pristine.
