LinkedIn Post Dimensions & Image Sizes Guide

The Ultimate Guide to LinkedIn Post Dimensions: Size It Right, Boost Your Reach

Visual content rules the professional feed. Whether you are building your personal brand or scaling a company page, posting a pixelated or awkwardly cropped image can instantly derail your credibility. LinkedIn’s algorithms heavily favor clean, engaging visual assets—but only if they fit the platform’s specific containers.

To help you skip the guesswork, here is the ultimate, up-to-date cheat sheet for LinkedIn post dimensions and asset sizes.

1. Standard Post Image Dimensions (Single Image)

When you upload a standalone photo to your feed, you have three primary aspect ratios to choose from. Picking the right one depends heavily on your content type and whether your audience is browsing on desktop or mobile.

| Format | Recommended Dimensions | Aspect Ratio | Best Used For |
| :— | :— | :— | :— |
| Landscape | 1200 x 627 px | 1.91:1 | Data visualizations, infographics, horizontal photography |
| Square | 1200 x 1200 px (or 1080 x 1080 px) | 1:1 | Classic product shots, balanced graphic quotes |
| Vertical / Portrait | 1080 x 1350 px (or 1200 x 1500 px) | 4:5 | Mobile-first content, tall infographics, high-impact storytelling |

Pro Tip: Vertical images (4:5) take up significantly more real estate on mobile feeds, stopping the scroll much faster than landscape or square alternatives.

2. Specialized Post Formats

Beyond standard photos, LinkedIn supports dynamic formats that require unique sizing considerations:

• Link Previews: When you drop a URL into a post, LinkedIn automatically pulls a thumbnail. For optimal control, make sure the destination website uses an Open Graph image sized at 1200 x 627 px (1.91:1).
• Carousel & Document Posts (PDFs): Document carousels are a powerhouse for engagement. Use a square (1080 x 1080 px) or vertical portrait (1080 x 1350 px) layout per page. Always export your slides as a clean, high-resolution PDF.
• Native Videos:
  • Landscape: 1920 x 1080 px (16:9)
  • Square: 1080 x 1080 px (1:1)
  • Max file size: Up to 5 GB, with durations ranging from 3 seconds to 10 minutes.

3. Profiles & Company Pages

Your first impression starts well before your first post. Make sure your profile assets look crisp:

• Personal Profile Photo: 400 x 400 px minimum (1:1 aspect ratio). Remember that LinkedIn crops profile pictures into a circle, so keep your face centered.
• Personal Background Banner: 1584 x 396 px (4:1 aspect ratio). Watch out: Mobile viewports crop the sides of your banner, so keep vital information and text safely centered within a middle safe zone.
• Company Page Logo: 400 x 400 px (1:1).
• Company Page Cover Banner: 1128 x 191 px.

4. Golden Rules for Flawless LinkedIn Visuals

• Watch the File Size Cap: Standard photo uploads are capped at 5 MB. Stick to optimized JPEGs for photographs and PNGs for graphics featuring sharp text or transparent elements.
• Mind the Text-to-Image Ratio: Keep text overlays clean and legible. If your font size is too small, it will become an unreadable blur on mobile screens.
• Prioritize Accessibility: Always add descriptive alt text to your images before publishing. It improves accessibility for visually impaired professionals and gives your post an extra layer of SEO visibility.
