LinkedIn Post Image Size Guide for 2026: Best Dimensions

Master the Grid: The Definitive Guide to LinkedIn Post Image Sizes

When you scroll through your professional feed, crisp visuals instantly stop your thumb. But there is nothing quite as frustrating as spending hours crafting a post only to find your carefully designed graphic awkwardly cropped or pixelated.

Because over 60% of LinkedIn users browse on mobile devices, understanding the exact dimensions for your images is essential for driving engagement and maintaining a professional brand.

The Three Core LinkedIn Post Image Formats

LinkedIn supports three primary aspect ratios for standard feed images. Choosing the right one depends entirely on the type of content you are sharing.

• Landscape (1200 × 627 pixels | 1.91:1 Aspect Ratio): This is LinkedIn’s traditional format, heavily used for link previews and corporate announcements. While it looks clean on a widescreen desktop monitor, it occupies less vertical space on mobile phones.
• Square (1080 × 1080 pixels | 1:1 Aspect Ratio): The ultimate middle-ground choice. Square posts render reliably across both desktop and mobile platforms without surprise cropping, making them a safe and popular option for infographics, quotes, and event promos.
• Portrait (1080 × 1350 pixels | 4:5 Aspect Ratio): If your primary goal is maximum engagement, portrait is your best bet. By taking up significantly more physical feed space on mobile screens, tall graphics naturally capture more attention.

Quick Reference: LinkedIn Post Dimensions

| Format | Dimensions | Aspect Ratio | Best For |
| :— | :— | :— | :— |
| Landscape Post | 1200 × 627 px | 1.91:1 | Link shares, blog previews, press releases |
| Square Post | 1080 × 1080 px | 1:1 | Infographics, quote cards, headshots |
| Portrait Post | 1080 × 1350 px | 4:5 | Mobile-first content, high-impact visuals |
| Carousel Slide | 1080 × 1080 px (or 1080 × 1350 px) | 1:1 or 4:5 | Multi-page document posts / PDFs |

Beyond the Feed: Profile and Banner Dimensions

Your post images are only part of the equation. To maintain a cohesive professional presence, ensure your profile elements match the optimal specifications:

• Profile Picture: Upload a square image at least 400 × 400 pixels (1:1 ratio). Remember that LinkedIn displays your profile picture inside a circular frame, so keep your face or logo centered and away from the tight corners.
• Background Banner: The desktop banner requires 1584 × 396 pixels (4:1 ratio). Keep in mind that mobile layouts slightly alter how banners display, so it is best to keep critical text and logos toward the center.

Best Practices for Crisp Uploads

1. Watch the File Size: Keep standard image files under 5 MB. LinkedIn supports common formats like JPG, PNG, and WebP, but PNG is generally preferred if your graphic contains sharp text or line art.
2. Design for Mobile First: Since the vast majority of your audience views content on phones, prioritize portrait or square layouts and avoid crowding text near the absolute edges of your design canvas.
3. Maintain Consistency: If you are sharing a multi-image post or a carousel deck, stick to a uniform aspect ratio throughout to give your content a polished, editorial look.
