Why You Should Switch to Portrait Ads (1080×1350)
The “Mobile First” Advantage
Over 57% of LinkedIn traffic is mobile. Standard landscape images (1200×627) look small on a phone screen. Portrait images (1080×1350) take up nearly 2x the vertical screen space, forcing users to pay attention as they scroll.
Higher Click-Through Rates (CTR)
Because they occupy more physical space on the screen, vertical ads historically generate higher engagement rates. They allow for larger typography and clearer visuals, which is critical for B2B messaging.
Design Best Practices
Since 1080×1350 is a tall format, keep your key value proposition in the center or top third of the image. Avoid putting text too close to the very bottom, as mobile UI overlays (like “Learn More” buttons) might cover it.
