LinkedIn Carousel Size Guide 2026: Dimensions & Best Practices
LinkedIn carousel posts are one of the highest-engagement formats on the platform. Getting the dimensions right ensures your content looks polished on every device and maximizes your reach in the feed.
Recommended LinkedIn Carousel Dimensions
| Aspect Ratio | Pixel Size | Best For |
|---|---|---|
| 1:1 (Square) | 1080 x 1080 px | Most versatile, works on all devices |
| 4:5 (Portrait) | 1080 x 1350 px | Maximum screen real estate in the feed |
| 16:9 (Landscape) | 1920 x 1080 px | Presentations and data-heavy slides |
The Sweet Spot: 1080 x 1080 px
Square slides (1:1) are the most reliable choice for LinkedIn carousels. They render consistently across desktop and mobile, and they give you a balanced canvas for text, images, and branding elements.
Portrait slides (4:5) take up more vertical space in the feed, which can boost engagement. However, they may get cropped on some desktop views, so make sure your key content stays within the safe zone.
File Specifications
- Format: PDF (for native carousel upload) or individual images (PNG/JPG)

- Color mode: RGB (not CMYK)
How Many Slides Should You Use?
Data from top-performing LinkedIn carousel posts shows clear patterns:
- 8-12 slides: Optimal for engagement. Enough depth to deliver value without losing attention.
- 5-7 slides: Good for quick tips, listicles, and bite-sized insights.
- 13-20 slides: Works for in-depth tutorials, case studies, and comprehensive guides.
Posts with fewer than 5 slides tend to underperform because they don't give readers enough reason to keep swiping. Posts with more than 20 slides see diminishing returns on engagement.
Best Practices for LinkedIn Carousels
1. Hook on Slide 1
Your first slide is your headline. It needs to be compelling enough to stop the scroll and motivate the swipe. Use a bold statement, a surprising statistic, or a clear promise of value.
2. One Idea Per Slide
Keep each slide focused on a single point. Cluttered slides with multiple concepts reduce readability and comprehension. White space is your friend.
3. Consistent Branding
Use the same colors, fonts, and logo placement throughout your carousel. This builds brand recognition and makes your content look professional.
4. End with a CTA
Tell readers what to do next. Whether it's commenting their thoughts, following your profile, saving the post, or visiting your website, always close with a clear call-to-action.
5. Use Large Text
Body text should be at least 24px to be readable on mobile devices. Headlines should be 36px or larger. Remember that most LinkedIn users browse on their phones.
Common Mistakes to Avoid
- Too much text per slide: If it takes more than 5 seconds to read a slide, you have too much text.
- Low contrast text: Ensure your text has enough contrast against the background. Dark text on light backgrounds (or vice versa) is essential.
- No visual hierarchy: Use size, weight, and color to guide the reader's eye to the most important information first.
- Forgetting the mobile experience: Always preview your carousel on a phone screen before publishing.
