What is the LinkedIn 1080×1080 Square?
While LinkedIn is known for the 1200×627 “Link Share” size, the 1080 x 1080 Square is rapidly becoming the top performer for mobile Sponsored Content.
Because most LinkedIn traffic now comes from mobile apps, the square format takes up significantly more vertical screen space than the traditional rectangle, leading to higher engagement rates.
Why Use 1080×1080 on LinkedIn?
- Mobile Dominance: Square images look larger and bolder on the mobile news feed.
- Carousel Ads: This is the mandatory format for LinkedIn Carousel ads (document slider ads).
