The Ultimate LinkedIn Image Size Guide: Dimensions for Every Post, Profile, and Banner

First impressions on LinkedIn happen in milliseconds. Whether a potential client, hiring manager, or future business partner lands on your personal profile, a company page, or scrolls past your latest post, visuals set the tone for your credibility.

Yet, nothing kills professional momentum quite like a stretched company banner, a pixelated graphic, or a profile picture with your forehead awkwardly cropped out by a circular mask.

To help you put your best foot forward, this comprehensive guide covers every essential LinkedIn image dimension, helping your brand look crisp, professional, and optimized for both desktop and mobile feeds.

1. Personal Profile Images: Your Digital Business Card

Your personal profile is your landing page. Getting these two foundational assets right ensures you look sharp from the very first glance.

• Profile Photo
  • Recommended Dimensions: $400 times 400$ pixels (or larger square)
  • Aspect Ratio: $1:1$ (Circular crop)
  • Maximum File Size: $8text{ MB}$
  • Pro Tip: LinkedIn displays your profile photo as a small circle. Upload a high-resolution square image with your face centered. Keep important elements away from the very edges so they aren’t clipped by the circular frame.
• Personal Background Banner
  • Recommended Dimensions: $1584 times 396$ pixels
  • Aspect Ratio: $4:1$
  • Maximum File Size: $8text{ MB}$
  • Pro Tip: Your profile picture overlays the bottom-left corner of your banner. Keep text, logos, and critical design elements on the right two-thirds of the image to avoid an awkward overlap.

2. Feed Post Sizes: Maximizing Engagement

With the majority of LinkedIn traffic coming from mobile devices, choosing the right post dimensions dictates how much screen real estate your content commands.

| Format | Dimensions | Aspect Ratio | Best Used For |
| :— | :— | :— | :— |
| Landscape | $1200 times 627$ px | $1.91:1$ | Link previews, external article shares, and wide-format graphics. |
| Square | $1080 times 1080$ px | $1:1$ | Versatile all-rounder; great for quote cards, clean infographics, and general updates. |
| Portrait | $1080 times 1350$ px | $4:5$ | Mobile dominance. Occupies the most feed space on phones, driving higher view times and engagement. |

• Rule of Thumb: If you want to stop the scroll, lean toward the portrait ($1080 times 1350$) format. Avoid uploading images narrower than $1200$ pixels wide for landscape/square assets to ensure they don’t look soft on high-resolution retina displays.

3. Company Page Branding

Company pages require precise dimensions to project enterprise-grade polish.

• Company Logo:
  • Recommended Dimensions: $400 times 400$ pixels (Minimum $300 times 300$ px).
  • Displayed as a square on desktop search results and notifications, so center your icon cleanly.
• Company Page Cover Banner:
  • Recommended Dimensions: $1512 times 256$ pixels
  • Maximum File Size: $3text{ MB}$ to $8text{ MB}$
  • Note: Ensure you use the updated $1512 times 256$ spec rather than older legacy dimensions ($1128 times 191$) to prevent distortion or unexpected cropping.

4. Carousels, Documents, and Video Assets

Rich media formats perform exceptionally well on LinkedIn, but they have their own structural rules.

• Carousels & Document Posts (PDF/PPT):
  • Recommended Dimensions: $1080 times 1080$ px (Square) or $1080 times 1350$ px (Portrait).
  • Keep file sizes under $10text{ MB}$ per slide/document. Square or portrait PDF slide decks are ideal for step-by-step guides and thought-leadership breakdowns.
• Native Video:
  • Recommended Dimensions: $1920 times 1080$ pixels ($16:9$ landscape) or $1080 times 1080$ pixels ($1:1$ square). Vertical video ($9:16$) is also fully supported.
  • Keep files under $200text{ MB}$ and ensure lengths stay between 3 seconds and 10 minutes. Because many users browse with sound off, always bake in open captions.

Quick Export Checklist for Sharp Graphics

Before hitting upload on your next piece of content, run through this quick quality control check:

1. Color Space: Export your designs in sRGB. Using Adobe RGB or ProPhoto can cause colors to look dull or shifted once rendered on LinkedIn.
2. File Format: Stick to PNG for graphics containing clean lines, vector text, or logos. Use JPG for photographic imagery to keep file sizes nimble.
3. File Size Optimization: Keep feed images between $200text{ KB}$ and $500text{ KB}$ to ensure they load instantly without aggressive platform compression.
