The Ultimate Guide to LinkedIn Post Image Sizes: Stop Blurry Uploads and Boost Engagement

You have spent hours crafting the perfect LinkedIn post. The hook is sharp, the insights are actionable, and the copy is primed to drive conversation. But when you hit publish, the attached image looks pixelated, awkward, or worse—awkwardly cropped right across the focal point.

Visuals on LinkedIn can make or break your reach. Because the platform’s algorithm favors dwell time (how long users pause on your content), an eye-catching, perfectly proportioned image is your ticket to stopping the endless scroll.

This comprehensive guide breaks down the exact LinkedIn post image sizes you need to know, covering single-image feeds, carousels, link previews, and profile assets to keep your brand looking sharp.

1. Single Image Posts: The Core Formats

When publishing a standalone image to your feed, you generally have three layout options. Choosing the right one depends on your content type and whether your audience is primarily viewing via desktop or mobile.

• Square (1:1 Ratio) — 1200 x 1200 pixels
  • Best for: General graphics, quote cards, product photos, and cross-platform sharing.
  • Why use it: Square is the safest all-rounder. It renders cleanly on both desktop and mobile devices without suffering aggressive cropping.
• Vertical / Portrait (4:5 Ratio) — 1080 x 1350 pixels (or 1200 x 1500 pixels)
  • Best for: Infographics, deep-dive breakdowns, storytelling graphics, and mobile-first content.
  • Why use it: Because the majority of LinkedIn traffic is mobile, vertical posts take up the maximum allowable feed space on a phone. More screen real estate translates directly to higher visibility and stronger engagement.
• Landscape (1.91:1 Ratio) — 1200 x 627 pixels
  • Best for: Photography, panoramic shots, or wide data visualizations.
  • Why use it: This is the classic horizontal format. While great for traditional photos, it leaves a lot of empty vertical space on mobile screens.

2. Special Post Types and Documents

Beyond standard static graphics, LinkedIn supports several rich media formats that require precise dimensions to look professional:

• Carousel / Document Posts (PDFs):
  • Recommended Size: 1080 x 1080 px (Square) or 1080 x 1350 px (Portrait)
  • Tip: Design your multi-slide decks in a portrait 4:5 ratio so they command more visual dominance as users swipe through them on mobile.
• Link Previews:
  • Recommended Size: 1200 x 628 px (1.91:1 ratio)
  • Tip: When you paste a URL into a post, LinkedIn automatically pulls the Open Graph (og:image) tag from your website. Ensure your blog posts feature an image matching these dimensions to prevent your preview card from collapsing into an unappealing thumbnail.
• Multi-Image Posts (2 to 20 images):
  • Recommended Size: Design each image to a consistent 1200 x 1200 px square.
  • Tip: The layout of a multi-image gallery is dictated entirely by the first image you upload. If the first image is landscape, it will anchor the top row; if it’s square or portrait, it will stack neatly down the left column.

3. Profile and Company Page Essentials

Your post visuals grab attention, but your profile is your digital storefront. Don’t let low-resolution banner images undermine your credibility.

• Personal Profile Picture: 400 x 400 pixels minimum (800 x 800 pixels recommended). Keep your face centered, as LinkedIn displays profile photos inside a circular crop.
• Personal Background Banner: 1584 x 396 pixels (4:1 ratio). Keep key text and logos away from the far edges, as mobile viewports crop the sides differently than desktop.
• Company Page Logo: 300 x 300 pixels.
• Company Cover Photo: 1128 x 191 pixels.

Quick Technical Checklist for Flawless Uploads

1. File Formats: Stick to JPEG for photographs and complex color gradients (smaller file sizes) and PNG for graphics containing text, line art, or logos (lossless sharpness).
2. File Size Limits: Keep single-image files under 5 MB for feed posts.
3. Avoid Upscaling: Never stretch a tiny image to meet LinkedIn’s dimensions. Always export your designs at or above the recommended pixel counts to prevent the platform from guessing missing pixels and creating a blurry finish.

By aligning your assets with these precise specs, you’ll ensure your content always looks crisp, professional, and optimized to capture attention right inside the feed.
