The Ultimate Guide to LinkedIn Post Dimensions: Stop Getting Cropped Out

You’ve spent hours drafting the perfect hook, crafting an insightful commentary, and choosing a stellar visual. You hit publish, and—disaster. Your carefully designed text is chopped in half, your company logo is floating off-screen, or your crisp graphic looks like it was put through a blender.

Nothing kills the momentum of a professional post faster than awkward, pixelated image cropping.

Mastering LinkedIn post dimensions is no longer just a “nice-to-have” graphic design chore; it is a fundamental pillar of modern professional branding. Because LinkedIn’s algorithm heavily rewards dwell time, visual assets that capture attention and display cleanly across both desktop and mobile devices are your ticket to breaking through the noise.

Let’s break down the exact dimensions, aspect ratios, and design strategies you need to make every pixel count.

1. Single Image Feed Posts: Choosing Your Weapon

When publishing a standalone image to your feed, you have three primary aspect ratio options. Each serves a distinct psychological and spatial purpose in the user’s feed.

A. The Square Post (1:1 Ratio) — The Reliable All-Rounder

• Recommended Dimensions: 1200 × 1200 pixels (or 1080 × 1080 pixels)
• Max File Size: 5 MB to 10 MB
• Best Used For: Infographics, data visualizations, quote cards, and cross-platform sharing from Instagram.
• Why it works: Square posts strike a wonderful balance. They take up noticeably more horizontal and vertical footprint than landscape images, giving you a strong presence on desktop without risking awkward cut-offs on mobile.

B. The Vertical / Portrait Post (4:5 Ratio) — The Scroll-Stopper

• Recommended Dimensions: 1080 × 1350 pixels
• Max File Size: 5 MB to 10 MB
• Best Used For: Step-by-step breakdowns, tall infographics, and narrative storytelling visuals.
• Why it works: Vertical posts dominate mobile real estate. Because over 60% of LinkedIn consumption happens on smartphones, a 4:5 ratio forces users to slow down their thumb-scrolling. Pro tip: Avoid going taller than 4:5 (such as 9:16 Instagram Story dimensions), or LinkedIn will automatically crop the top and bottom of your image in the feed.

C. The Landscape Post (1.91:1 Ratio) — The Classic View

• Recommended Dimensions: 1200 × 627 pixels
• Max File Size: 5 MB to 10 MB
• Best Used For: Traditional photography, landscape graphics, and standard link previews.
• Why it works: This is LinkedIn’s default format for link previews. If you are sharing an external blog post or website, always ensure your Open Graph image matches 1200 × 627 px so it doesn’t default to a messy, auto-generated square crop with white letterboxing.

2. Carousel & Document Posts (The Engagement Goldmine)

If you aren’t utilizing LinkedIn document/carousel posts (where users swipe through multi-page PDFs), you are missing out on one of the platform’s highest-performing content formats. Carousels regularly generate outsized engagement because they encourage active interaction.

• Slide Dimensions (Square): 1080 × 1080 pixels (1:1)
• Slide Dimensions (Portrait): 1080 × 1350 pixels (4:5)
• Max File Size: 100 MB
• Format: Upload as a PDF document.

The Design Secret: Stick to a consistent background color scheme across all slides. Ensure your font sizes are large enough to read effortlessly on a smartphone screen (minimum 24–30pt for body text).

3. LinkedIn Video Specifications

Video content continues to expand its footprint on the platform. Whether you’re uploading talking-head clips or polished company reels, adhere to these guardrails:

• Landscape Video: 1920 × 1080 pixels (16:9 ratio)
• Square Video: 1080 × 1080 pixels (1:1 ratio)
• Vertical Video: 1080 × 1920 pixels (9:16 ratio)
• Duration: 3 seconds to 10 minutes
• Max File Size: Up to 5 GB
• Formats: MP4 (strongly recommended), MOV, or WebM.

4. Profiles and Company Pages: The Frameworks

Your posts live within the ecosystem of your personal profile or company page. If your banners are misaligned, your first impression suffers.

Personal Profile

• Profile Photo: 400 × 400 pixels (1:1 square, cropped into a circle by the platform). Center your face and keep headshots occupying roughly 60% of the frame.
• Cover / Banner Image: 1584 × 396 pixels (4:1 ratio). Warning: Mobile devices crop the outer edges of personal banners. Keep essential text, branding, and contact details inside a central “safe zone”.

Company Pages

• Company Logo: 400 × 400 pixels (1:1 square).
• Page Cover Image: 1128 × 191 pixels (roughly 6:1 ratio).

Pro-Tips for Flawless Execution

1. Mind the Compression: Always export your graphic designs as PNG-24 if they contain heavy typography or crisp UI mockups. Use JPEG for standard photographs to keep file sizes well under the limits without sacrificing visual fidelity.
2. Add Alt Text: Don’t skip accessibility. Adding descriptive alt text to your images not only helps visually impaired professionals engage with your content, but it also gives a minor boost to your post’s contextual SEO.
3. Test Before You Schedule: Drop your final design into a preview mockup tool or check it via a mobile device before scheduling it. What looks breathtaking on a 27-inch desktop monitor can easily become illegible when shrunk down to a 6-inch phone screen.
