LinkedIn Post Image Size Guide for 2026

Mastering LinkedIn Post Image Sizes: The Definitive Guide

In the fast-moving world of professional networking, first impressions happen in milliseconds. When you scroll through your LinkedIn feed, what catches your eye first? Usually, it is not a wall of text—it is a striking visual.

However, even the most brilliant graphic or powerful photo can fall flat if it is awkwardly cropped, pixelated, or warped by LinkedIn’s automatic formatting. Getting your dimensions right is the secret weapon to turning casual scrollers into engaged followers, clients, or collaborators.

Here is everything you need to know about LinkedIn post image sizes to make your content pop.

The Big Three: Standard Post Image Sizes

LinkedIn supports three primary aspect ratios for native image posts. Choosing the right one depends entirely on the story you want to tell and the device your audience is using.

• Landscape (1.91:1 Aspect Ratio)
  • Dimensions: 1200 x 627 pixels
  • Best for: Link previews, horizontal landscape photography, and clean corporate graphics. This is LinkedIn’s traditional default size and ensures compatibility across web and mobile views without unexpected cropping.
• Square (1:1 Aspect Ratio)
  • Dimensions: 1080 x 1080 pixels (or up to 1200 x 1200 pixels)
  • Best for: Infographics, data visualizations, quote graphics, and product shots. Square images occupy more feed real estate than landscape images, giving your content a better chance of stopping the scroll.
• Portrait / Vertical (4:5 Aspect Ratio)
  • Dimensions: 1080 x 1350 pixels (or 1200 x 1500 pixels)
  • Best for: Step-by-step guides, tall infographics, and mobile-first visual storytelling. Portrait posts take up the maximum allowable vertical real estate on mobile feeds, making them heavy hitters for driving engagement. (Note: Avoid going taller than 4:5, or LinkedIn will automatically crop the bottom of your image).

Beyond Standard Posts: Carousels, Links, and Profiles

Different types of content require different dimensions to look their absolute best. Keep these specifications handy for other key areas of your LinkedIn presence:

1. Carousel and Document Posts (PDFs)

If you love publishing multi-slide thought leadership decks, documents uploaded as PDFs are your best friend.

• Dimensions: 1080 x 1080 pixels (Square) or 1080 x 1350 pixels (Portrait).
• Pro Tip: Design your slides natively in design tools like Canva at these exact dimensions and export them as a single PDF. Carousels consistently generate some of the highest engagement rates on the platform.

2. Link Previews

When you share an external article or blog post URL, LinkedIn automatically pulls an open-graph preview image.

• Dimensions: 1200 x 627 pixels.
• Pro Tip: Always double-check that your website or blog features a properly optimized Open Graph image. If the thumbnail looks broken or misaligned, it can tank your click-through rate.

3. Profiles and Banners

Your profile is your digital landing page. Make sure it shines with crisp imagery:

• Profile Photo: Aim for 400 x 400 pixels (1:1 square). Keep your face centered, as LinkedIn automatically crops photos into a circle.
• Background Banner: Use 1584 x 396 pixels (4:1 aspect ratio). Keep important branding and text centered within a 1200-pixel safe zone so it doesn’t get cut off on mobile screens.

Pro Tips for Flawless LinkedIn Visuals

1. Prioritize Mobile Viewers: Over half of LinkedIn traffic originates from mobile devices. Vertical and square images dominate smaller screens and block out competing distractions.
2. Mind the Text Overlays: Keep essential text large and centered. If your text touches the extreme edges of an image, mobile rendering may cut it off.
3. Use the Right File Format: Stick to PNG for graphics featuring sharp lines, text, or logos to prevent pixelation, and JPEG for standard photographs.
4. Never Skip Alt Text: Adding descriptive alt text to your images not only boosts accessibility for visually impaired users but also aids in overall search engine visibility.

By aligning your creative assets with these exact dimensions, you ensure that your professional content looks sharp, intentional, and ready to command attention in any feed.
