Best Aspect Ratio for LinkedIn Ads
LinkedIn favors clean, legible creative for professionals. Use ratios that maximize clarity in the feed.
Understanding LinkedIn aspect ratios
Professional audiences often browse on mobile and desktop during work hours, so legibility is paramount. Simple layouts with large type and product clarity outperform dense creative. A suite of 1:1, 4:5, and 16:9 variants covers most LinkedIn placements with minimal rework. Safe zones protect headlines and logos from UI compression. Plan exports together so testing and trafficking stay straightforward.
The best aspect ratio for LinkedIn ads depends on format and device. 1:1 is broadly reliable for single image and in‑feed video; 4:5 increases presence on mobile feeds; 16:9 fits landscape placements and desktop contexts. Keep CTAs consistent across variants to reinforce action. Use captions for video since many professionals browse muted. Validate clarity on both high‑DPI laptops and phones.
Why LinkedIn aspect ratio choice matters
Choosing the right LinkedIn aspect ratio matters because B2B decision‑makers skim quickly and need immediate clarity. Native ratios and large typography improve comprehension and CTR. Consistent ratio suites simplify testing and reporting across campaigns.
- 1:1 and 4:5 increase feed presence on mobile
- Consistent ratios simplify campaign testing and reporting
- Proper sizing prevents small, hard‑to‑read creatives
How LinkedIn placements work
LinkedIn adds captions and UI that can compress available space in feed, especially on mobile. Keep headlines concise, benefits obvious, and brand marks large enough to read.
Export square and portrait variants for feed coverage, with 16:9 for landscape needs such as some desktop contexts. Always include captions for video, as many professionals browse with sound off.
- Keep headlines short and benefits obvious.
- Use large type and high contrast for mobile legibility.
- Prefer 1:1 or 4:5 for maximum feed impact.
- Include captions for video; many watch muted at work.
- Maintain consistent brand system across all aspect variants.
