Horizontal LinkedIn Post Size and Image Dimensions Guide

Understanding Horizontal LinkedIn Post Size

If you're aiming to boost professional engagement on LinkedIn, mastering the horizontal LinkedIn post size is a must. This landscape orientation—where width exceeds height—is perfect for wide shots, team photography, charts, banners, and infographics that need breathing space across the feed. Knowing how to design and size these posts correctly ensures they render crisply on both desktop and mobile, while maintaining brand consistency.

Horizontal images can:

• Showcase panoramic views or wide diagrams effectively
• Give a professional, brochure-like feel to your post
• Perform better for content that needs text overlay without feeling cramped
• Appear consistent with banner-like branding for campaigns

Choosing the right orientation is key: on LinkedIn, images that are optimally sized in horizontal format look cleaner, display properly across devices, and aren't cut off by automatic cropping.

Current Horizontal LinkedIn Image Dimensions

LinkedIn currently supports several image aspect ratios, but for horizontal posts in the feed, the following dimensions are ideal:

Pro Tip: Always export in PNG for sharper text overlays and crisp lines. JPEG is fine for photography-heavy content, but keep compression settings high quality.

Best Practices for Designing Horizontal LinkedIn Posts

Follow these guidelines when designing landscape-oriented LinkedIn posts:

1. Safe Zone for Text – Keep critical text within the central 1000 px width to avoid cropping on smaller screens.
2. Adequate Padding – Use at least 40–60 px margin from edges to prevent UI overlap.
3. Consistent Font Size – Choose legible font sizes between 18–36 pt for overlay titles.
4. Visual Hierarchy – Arrange elements from left to right with clear focus points.
5. Color Contrast – Ensure text color contrasts well against the background image.

Sample CSS to simulate safe zones during design:

.canvas {
  position: relative;
  width: 1200px;
  height: 627px;
  background: #eef2f5;
}
.safe-zone {
  position: absolute;
  left: 80px;
  right: 80px;
  top: 60px;
  bottom: 60px;
  border: 2px dashed #ff9900;
}

1. Insights Tab – Check impressions, clicks, and CTR for each post.
2. Compare Formats – Tag posts internally to monitor engagement differences between horizontal, vertical, and square.

Monitoring performance over 4–6 weeks enables data-driven decisions.
