The Ultimate Guide to LinkedIn Image Sizes: Master Every Dimension for Maximum Impact

First impressions matter—especially in a professional ecosystem where recruiters, clients, and potential business partners make split-second decisions about your credibility. On LinkedIn, your visual branding speaks volumes long before anyone reads a single word of your headline or “About” section.

Yet, there is little more frustrating than spending hours designing a striking graphic, only to watch LinkedIn stretch, blur, or awkwardly crop vital text out of frame.

To help you put your best digital foot forward, here is the complete, up-to-date guide to LinkedIn image sizes for profiles, company pages, posts, and ads.

Part 1: Personal Profile Image Dimensions

Your personal profile is your digital storefront. Getting the dimensions right ensures you look sharp, polished, and detail-oriented.

1. Profile Photo

• Recommended Size: 400 x 400 pixels (minimum 268 x 268 pixels)
• Aspect Ratio: 1:1 (Square, displayed as a circle)
• Max File Size: 3MB to 8MB (depending on account type)
• Formats: JPG or PNG
• Pro Tip: Keep your face centered and occupying roughly 60% to 70% of the frame. Because LinkedIn crops your photo into a circle, make sure important details aren’t hiding in the corners.

2. Personal Background Banner (Cover Photo)

• Recommended Size: 1584 x 396 pixels
• Aspect Ratio: 4:1
• Max File Size: 8MB
• Formats: JPG, PNG, or non-animated GIF
• Pro Tip: Designing a banner can be tricky because the layout shifts between desktop and mobile devices. Mobile apps tend to crop the edges more aggressively, and your circular profile photo overlaps the bottom-left corner of the banner. Keep crucial text, branding, and logos centered or slightly to the right to prevent them from getting covered or chopped off.

Part 2: Company Page Image Dimensions

If you are managing a brand or business page, the visual stakes are even higher. Consistency builds corporate trust.

• Company Logo: 300 x 300 pixels (PNG or SVG preferred for crisp scaling)
• Company Page Cover Image: 1128 x 191 pixels (Keep text centered and avoid clutter)
• Life Tab Hero Image: 1128 x 376 pixels
• Custom Module Images: 502 x 282 pixels

Part 3: LinkedIn Feed Post Sizes

Content formatting dictates how much screen real estate you command in the LinkedIn feed. Because roughly 60% of LinkedIn users browse via mobile devices, choosing the right aspect ratio directly impacts how long users linger on your post.

1. Landscape (Horizontal)

• Dimensions: 1200 x 627 pixels
• Aspect Ratio: 1.91:1
• Best For: Link shares, website previews, or broad landscape photography.
• Note: While it’s LinkedIn’s traditional format, it takes up minimal space on mobile feeds.

2. Square

• Dimensions: 1080 x 1080 pixels
• Aspect Ratio: 1:1
• Best For: General graphics, quote cards, and multi-image posts.
• Note: Square is a reliable, safe choice that renders cleanly across both desktop and mobile environments without unexpected cropping.

3. Portrait (Vertical) — The Engagement Winner

• Dimensions: 1080 x 1350 pixels
• Aspect Ratio: 4:5
• Best For: Infographics, deep-dive breakdowns, and high-impact visual statements.
• Note: Portrait posts dominate mobile screens, capturing more vertical real estate and naturally driving higher engagement rates.

Part 4: Special Content Formats (Carousels & Videos)

1. Document / Carousel Posts (PDF Slides)

• Slide Dimensions: 1080 x 1080 pixels (Square) or 1080 x 1350 pixels (Portrait)
• Max File Size: 100MB (Max 10MB per slide recommended)
• Formats: PDF, PPTX, or DOCX (PDF is standard)
• Pro Tip: Keep typography large and legible. Users swipe through carousels quickly, so make sure text isn’t crammed into the margins.

2. Video Posts

• Recommended Dimensions: 1920 x 1080 pixels (Landscape 16:9) or 1080 x 1080 pixels (Square)
• Alternative: 1080 x 1350 pixels (Portrait)
• Max File Size: Up to 5 GB
• Formats: MP4 or MOV

Quick Checklist for Flawless Uploads

1. Prioritize PNG for Graphics: If your image contains text, logos, or clean graphic lines, export as a PNG to prevent pixelation and compression artifacts. Use JPG for standard photographic imagery.
2. Design with Safe Zones in Mind: Always leave a padding buffer around the edges of banners and profile pictures to guard against auto-cropping.
3. Double-Check on Mobile: Before locking in a new banner or cornerstone post, view your profile or feed on a smartphone. What looks centered on a 27-inch desktop monitor can easily look misaligned on a mobile screen.

By matching your assets to these dimensions, you ensure your visual content looks professional, deliberate, and optimized to stop the scroll.
