The Ultimate Guide to LinkedIn Post Image Sizes: Stop Your Visuals from Getting Cropped

We’ve all been there: You spend hours crafting a brilliant piece of thought leadership, pair it with a graphic you designed down to the pixel, and hit publish. But when you check the live feed on your phone, your carefully centered text is chopped off, or your striking hero image looks like a blurry postage stamp.

On a professional network like LinkedIn, visual presentation is everything. Grainy, poorly cropped, or misaligned graphics immediately undermine your credibility. Because LinkedIn feeds are primarily consumed on mobile devices, mastering image dimensions isn’t just about technical compliance—it’s about maximizing real estate and stopping the scroll.

Whether you’re sharing a single-image post, setting up carousels, or polishing your company page, here is your complete, definitive guide to LinkedIn post image sizes.

1. The Core Feed Formats: Choosing the Right Shape

When uploading a standard image post to your personal profile or company page, you have three primary layout options. Knowing when to use each one can dramatically change your engagement rates.

A. Portrait / Vertical (1080 x 1350 pixels) — The Engagement Winner

• Aspect Ratio: 4:5
• Best For: Text-heavy infographics, step-by-step guides, charts, and mobile-first visual storytelling.
• Why it works: Portrait is widely considered the highest-performing format for the LinkedIn mobile feed. Because it takes up the maximum vertical space allowed before LinkedIn clamps or crops the view, it forces users to pause their scroll longer than any other format.
• Pro Tip: Treat 4:5 as a hard ceiling. If you upload a taller image (like a 9:16 story graphic), LinkedIn will automatically crop the top and bottom off.

B. Square (1080 x 1080 pixels) — The Safe All-Rounder

• Aspect Ratio: 1:1
• Best For: General brand announcements, team spotlights, quotes, and cross-platform publishing.
• Why it works: Squares are predictable. They render identically and look clean across desktop monitors, tablets, and smartphones without risking unexpected layout shifts. If you plan to syndicate the exact same graphic to Instagram, Facebook, and LinkedIn, 1080 x 1080 is your safest bet.

C. Landscape (1200 x 627 pixels) — The Link Preview Standard

• Aspect Ratio: 1.91:1
• Best For: Sharing external website articles, blog posts, or landscape-oriented photography.
• Why it works: While landscape images take up less vertical space in a mobile feed, they are essential when you are dropping a URL into a post and letting LinkedIn generate an automated preview card.

2. Specialized Content Formats: Carousels & Documents

Document posts (commonly known as LinkedIn carousels or slide decks) are among the most powerful tools for driving high dwell-time and massive reach.

• Recommended Slide Dimensions: 1080 x 1080 px (Square) or 1080 x 1350 px (Portrait)
• File Format: PDF, PPTX, or DOCX (PDF is heavily preferred to lock in formatting)
• Max File Size: Up to 100MB

When designing carousels, stick to the 1080 x 1350 portrait ratio if you want your slides to dominate the screen, ensuring text elements are large enough to be read effortlessly on a smartphone.

3. Profile & Branding Assets Cheat Sheet

Your posts aren’t the only things that need precise sizing. Your overall profile architecture sets the stage for your brand:

• Personal Profile Picture: 400 x 400 pixels (displayed as a circle; keep your face centered)
• Personal Cover/Banner Photo: 1584 x 396 pixels (4:1 ratio)
• Company Page Logo: 400 x 400 pixels (Transparent PNG recommended)
• Company Page Cover Photo: 1512 x 256 pixels
