Master the Frame: The Ultimate Guide to LinkedIn Post Image Sizes

Visuals are no longer optional on LinkedIn—they are the hook that stops the scroll. Whether you are building a personal brand, running a company page, or sharing industry insights, a pixelated or awkwardly cropped image can instantly undermine your credibility.

Because LinkedIn serves content across everything from ultra-wide desktop monitors to compact mobile phones, getting your image dimensions right is essential. This guide breaks down the ideal sizes for LinkedIn post images, carousels, and profile assets to keep your content looking crisp and professional.

1. Standard Feed Image Sizes

When uploading a single image to your feed, you have three primary orientation options. Choosing the right one depends on how much screen space you want to command.

• Square (1:1 Ratio): 1080 x 1080 pixels
  • The Gold Standard: Square images are the safest, most versatile choice. They display predictably across both desktop and mobile feeds, making them ideal for infographics, quote cards, and announcements.
• Portrait / Vertical (4:5 Ratio): 1080 x 1350 pixels
  • The Engagement Driver: Because the majority of LinkedIn users browse on mobile devices, portrait images excel by taking up more vertical real estate. This extra height naturally increases view time and drives higher engagement.
• Landscape (1.91:1 Ratio): 1200 x 627 pixels
  • The Classic Choice: This is the standard size traditionally used for link previews and web banner shares. While it looks clean on wide desktop screens, it appears smaller and leaves more dead space on mobile phones.

Pro Tip: Keep your maximum file size under 5 MB, and stick to high-quality JPG or PNG formats for photos and text-heavy graphics.

2. Carousel & Document Post Sizes

Document posts (which display as swipeable carousels) are one of the most powerful organic reach tools on LinkedIn. To ensure your slides look professional and legible, design them using these specifications:

• Square Slides: 1080 x 1080 pixels (1:1 aspect ratio)
• Portrait Slides: 1080 x 1350 pixels (4:5 aspect ratio)

Export your design as a PDF before uploading. Portrait carousels are particularly effective on mobile because they draw the reader’s eye downward, encouraging users to swipe through to the final slide.

3. Profile & Branding Dimensions

Your content images grab attention, but your profile is your digital storefront. Make sure your core branding assets fit LinkedIn’s container guidelines:

| Asset Type | Recommended Dimensions | Aspect Ratio | Format / Notes |
| :— | :— | :— | :— |
| Personal Profile Photo | 400 x 400 px | 1:1 | Displayed as a circle; keep your face centered. Max 8 MB. |
| Personal Cover Banner | 1584 x 396 px | 4:1 | Max 8 MB. Avoid placing key text in the bottom-left corner where the profile photo overlaps. |
| Company Page Logo | 400 x 400 px | 1:1 | Clear, recognizable branding asset. Max 4 MB. |
| Company Cover Photo | 1128 x 191 px | ~6:1 | Wide banner format; keep important details safe in the center zone. |

Summary Checklist for Success

1. Design Mobile-First: Since most of your audience views LinkedIn on a phone, favor square (1080 x 1080) or portrait (1080 x 1350) formats.
2. Never Go Too Small: Always upload at or above the recommended dimensions. Up-scaling a low-resolution image will cause LinkedIn’s compression algorithm to make it look blurry.
3. Double-Check Text Placement: Keep essential text and graphics away from the extreme edges of your templates to prevent unexpected clipping.

By aligning your assets with these dimensions, you ensure your professional brand always looks polished, intentional, and ready to engage.
