The Ultimate Guide to LinkedIn Image Sizes

First impressions on LinkedIn happen in milliseconds. Before anyone reads your headline, pores over your work experience, or evaluates your recommendations, they see your visuals.

Yet, nothing undermines professional credibility quite like a pixelated headshot, a banner image cut off at awkward angles, or a text graphic with its edges sliced off by mobile formatting. LinkedIn aggressively compresses and crops images, meaning exact dimensions are the difference between a polished personal brand and a sloppy digital footprint.

This comprehensive guide breaks down the exact, up-to-date pixel dimensions for every single image asset on LinkedIn—from personal profiles and company pages to feed posts and carousels.

1. Personal Profile Images

Your profile is your digital landing page. These two spaces set the tone before a recruiter, client, or peer ever scrolls down.

Profile Photo

• Recommended Dimensions: $400 times 400$ pixels (minimum $268 times 268$ pixels)
• Aspect Ratio: 1:1 (displays in a circle)
• Max File Size: 3MB
• Formats: JPG or PNG
• Pro Tip: Keep your face centered, occupying roughly 60% of the frame. Because the image is cropped into a circle, avoid putting crucial elements or logos right in the extreme corners.

Personal Background Banner (Cover Photo)

• Recommended Dimensions: $1584 times 396$ pixels
• Aspect Ratio: 4:1
• Max File Size: 8MB
• Formats: JPG, PNG, or non-animated GIF
• The Trap to Avoid: The profile picture sits over the bottom-left corner of your banner, and mobile devices crop the left and right edges differently than desktop screens. Keep all text, logos, and focal points shifted toward the center-right to prevent them from getting covered or cut off.

2. Company Page Images

If you manage a brand or business page, the layout shifts slightly. Do not use personal profile banner dimensions for a company page.

• Company Logo: $300 times 300$ pixels (Square 1:1 ratio)
• Company Cover / Hero Image: $1128 times 191$ pixels (Note: It is often safest to design on a larger canvas with the same aspect ratio, like $4200 times 700$ pixels, to ensure high-density retina display sharpness).
• Life Tab / Custom Modules: Main hero images look best at $1128 times 376$ pixels, while gallery images should target $900 times 600$ pixels.

3. LinkedIn Feed Post Sizes

With over 60% of LinkedIn traffic originating from mobile devices, optimizing your feed posts for vertical screen real estate is non-negotiable.

| Post Format | Dimensions | Aspect Ratio | Best For |
| :— | :— | :— | :— |
| Landscape | $1200 times 627$ px | 1.91:1 | Link previews, external article shares, wide landscape photography |
| Square | $1080 times 1080$ px | 1:1 | Clean quote cards, standard infographics, product photos |
| Portrait | $1080 times 1350$ px | 4:5 | Deep-dive carousels, text-heavy graphics, maximum mobile thumb-stopping power |

• The Engagement Winner: While landscape works nicely for automated link cards, Portrait ($1080 times 1350$ px) takes up significantly more physical space on a smartphone feed. If you want higher dwell-time and visibility, design your native graphics vertically.
• File Limits: Keep single image files under 5MB. Stick to PNG if your image contains crisp typography and sharp logos; use JPG for natural photography.

4. Carousels & Document PDFs

Document posts (which display as swipeable slide decks or carousels) remain one of the highest-converting organic formats on LinkedIn.

• Recommended Dimensions: $1080 times 1080$ pixels (Square) or $1080 times 1350$ pixels (Portrait)
• Max File Size: 10MB per document
• Accepted Formats: PDF (Recommended), PPTX, or DOCX
• Pro Tip: Always export your design slides as a high-resolution PDF before uploading. Text rendered directly into a vector PDF remains razor-sharp on any screen size, whereas flat JPG slides can blur when zoomed or viewed on high-retina mobile displays.

Summary Checklist for Designers

1. Never upload raw screenshots directly into a design tool without locking in the canvas dimensions first; arbitrary sizes cause LinkedIn’s compression algorithm to introduce artifacts and blur.
2. Keep safe margins: Leave a 50px buffer around the edges of text-heavy feed posts so key insights never touch the outer border of the UI frame.
3. Double-check mobile view: Always preview your profile banner and scheduled posts on a physical smartphone before walking away.
