The Ultimate Guide to LinkedIn Post Dimensions

Whether you are building a personal brand, promoting a business, or sharing industry insights, visual content is key to capturing attention on LinkedIn. However, uploading an image without checking the dimensions can lead to awkward cropping, blurry text, or missed engagement.

Because the vast majority of LinkedIn users browse on mobile devices, knowing the exact pixel requirements ensures your content looks professional everywhere. This guide breaks down the optimal LinkedIn post dimensions for every content type.

1. Single Image Feed Posts

Single image posts are your bread and butter for quotes, infographics, and promotional graphics. You have three primary aspect ratio options depending on how much screen space you want to capture:

• Square (1:1 Aspect Ratio) — Recommended Default
  • Dimensions: 1080 x 1080 pixels (or 1200 x 1200 pixels)
  • Best for: General graphics, infographics, and quotes. It is the safest choice because it renders cleanly and predictably on both desktop and mobile feeds.
• Portrait / Vertical (4:5 Aspect Ratio) — Best for Mobile Engagement
  • Dimensions: 1080 x 1350 pixels
  • Best for: Stopping mobile scrolls. Because portrait posts take up the maximum vertical space allowed in a mobile feed, top creators frequently use this format to boost visibility and watch time.
• Landscape (1.91:1 Aspect Ratio)
  • Dimensions: 1200 x 627 pixels
  • Best for: Link previews and landscape photography. Note that while this is LinkedIn’s traditional format, it leaves more empty space on phone screens compared to square or portrait options.

Pro Tip: Keep individual photo uploads under 5 MB. LinkedIn accepts JPG, PNG, and WebP formats. Use PNG if your graphic contains sharp text or logos; use JPEG or WebP for photographs.

2. Link Previews

When you paste an external URL into a post, LinkedIn automatically pulls a preview thumbnail.

• Recommended Size: 1200 x 627 pixels (1.91:1)
• Tip: If the image preview looks broken or cropped incorrectly when you paste a link, ensure the website’s Open Graph (OG) image matches this exact landscape ratio.

3. Carousel / Document Posts (PDFs)

Document carousels are one of the highest-performing formats on LinkedIn for educational guides, slide decks, and step-by-step breakdowns.

• Recommended Size: 1080 x 1080 pixels (Square) or 1080 x 1350 pixels (Portrait)
• File Format: Export your slides directly as a PDF document before uploading.
• Specs: Keep individual slide text readable, and ensure your total file size stays under 100 MB.

4. Video Posts

Video content is prioritized heavily by the algorithm, whether you upload widescreen tutorials or mobile-first vertical clips.

• Square Video: 1080 x 1080 pixels (1:1)
• Landscape Video: 1920 x 1080 pixels (16:9)
• Vertical Video: 1080 x 1920 pixels (9:16)
• Specs: MP4 format is recommended. Videos can range from 3 seconds up to 10 minutes long, with a maximum file size of 5 GB.

5. Profile & Company Page Basics

Your branding elements set the stage before anyone even reads your posts. Make sure they fit these dimensions to avoid strange cropping:

| Asset Type | Recommended Dimensions | Aspect Ratio / Notes |
| :— | :— | :— |
| Personal Profile Photo | 400 x 400 pixels | 1:1 (Displayed as a circle; keep your face centered) |
| Personal Banner / Cover | 1584 x 396 pixels | 4:1 (Avoid placing key graphics in the bottom-left, where the profile picture overlaps) |
