The Ultimate Guide to LinkedIn Post Image Sizes: Stop Cropping Out Your Impact

When you scroll through your LinkedIn feed, what makes you stop? Is it a wall of text, or is it a crisp, eye-catching visual that commands the screen?

For modern professionals, creators, and brands, LinkedIn is no longer just a digital resume repository—it’s a dynamic publishing platform. Yet, nothing kills the momentum of a brilliant post faster than an awkwardly cropped graphic, a pixelated screenshot, or a link preview with its head chopped off.

Getting your image dimensions right is the secret weapon of high-performing LinkedIn profiles. This comprehensive guide breaks down every exact pixel dimension, aspect ratio, and best practice you need to master LinkedIn image sizing and maximize your professional reach.

Why LinkedIn Image Sizes Matter More Than You Think

LinkedIn’s algorithm relies heavily on dwell time—how long users pause to read or look at your post. High-quality, perfectly proportioned images naturally trap the thumb mid-scroll.

However, LinkedIn has strict container sizes. If your image doesn’t fit the platform’s native aspect ratios, the system will either:

• Crop it automatically, cutting off vital text, logos, or faces.
• Letterbox it, padding the sides with unattractive white or grey blank space.

Because more than 60% of LinkedIn traffic comes from mobile devices, designing for the phone screen is non-negotiable. Let’s look at the exact dimensions that keep your visuals sharp across every device.

The Big Three: Standard LinkedIn Post Image Sizes

When posting organic single images to your feed, three core sizes dominate the landscape. Choosing the right one depends entirely on your content strategy.

1. The Portrait Post (The Engagement Winner)

• Dimensions: 1080 x 1350 pixels
• Aspect Ratio: 4:5
• Best For: Infographics, step-by-step guides, tall quote cards, and storytelling graphics.

Why it works: A 4:5 portrait ratio is the absolute tallest frame the LinkedIn feed will render without cutting off the top and bottom. Because it consumes the maximum vertical real estate on mobile phones, it forces users to slow down and look. If you want maximum visibility and engagement, portrait is your go-to format.

• Caution: Avoid going taller than 4:5 (like 9:16 vertical video formats), or LinkedIn will aggressively crop your masterpiece.

2. The Square Post (The Safe, Versatile All-Rounder)

• Dimensions: 1080 x 1080 pixels
• Aspect Ratio: 1:1
• Best For: Product shots, branding graphics, dual-image grids, and everyday updates.

Why it works: If you aren’t sure what format to use, square is the safest bet. It renders seamlessly on both desktop monitors and mobile screens without unexpected cropping. It takes up significantly more feed space than a traditional landscape image, giving you a clean, balanced look.

3. The Landscape Post & Link Previews (The Classic)

• Dimensions: 1200 x 627 or 1200 x 628 pixels
• Aspect Ratio: 1.91:1
• Best For: Sharing external website links, blog posts, and wide photography.

Why it works: This is LinkedIn’s legacy post size. While it doesn’t dominate mobile screen space like a portrait graphic, it is essential for link previews. When you paste a URL into a post, LinkedIn automatically pulls the Open Graph image from that web page. If your website image isn’t set to 1200 x 627 pixels, LinkedIn will shrink it into a tiny thumbnail on the left or add awkward padding. Always optimize your website’s meta images to match this dimension.

Beyond the Feed: Carousels, Banners, and Profiles

Your feed posts are only part of the equation. To build a cohesive, professional brand presence, you need to nail the supporting imagery across your profile and page.

• Carousel / Document Posts (PDFs):
  • Recommended Size: 1080 x 1080 px (Square) or 1080 x 1350 px (Portrait) per page.
  • Tip: Carousels generate massive engagement. Export your slides as a clean, flattened PDF to preserve typography and layout integrity.
• Personal Profile Background (Banner):
  • Recommended Size: 1584 x 396 pixels (4:1 ratio).
  • Tip: Your profile picture and headline overlap the lower-left corner of your banner on desktop. Keep critical text, logos, and focal points shifted toward the center or right side.
• Personal Profile Photo:
  • Recommended Size: 400 x 400 pixels minimum (1:1 ratio).
  • Tip: LinkedIn crops your photo into a circle. Center your face, use a high-contrast background, and avoid putting fine-print logos in the corners.
• Company Page Cover Image:
  • Recommended Size: 1128 x 191 pixels (or uploaded larger at 4200 x 700 for high-DPI displays).

Technical Specs & Quick Checklist

Before you hit publish, keep these technical guardrails in mind to ensure your upload succeeds:

• File Formats: JPG, PNG, WEBP, or GIF. Use PNG for sharp text-heavy graphics and infographics; use JPG for photographs.
• File Size Limits: Keep organic images under 5 MB to 10 MB depending on the format. Extremely massive files can fail to upload or suffer from aggressive server-side compression.
• Add Alt Text: Always use LinkedIn’s built-in alt text option when uploading images. It improves accessibility for visually impaired users and helps optimize your post for inclusivity.
