LinkedIn Post Size: 1200x1200 (2026)
The best LinkedIn post image size is 1200x1200 pixels, a 1:1 square. Portrait 1080x1350 takes up even more feed space, and link previews render at 1200x627. Video runs from square to 16:9. Here's every in-feed spec with exact pixels.
The safe default. Full width in the feed on desktop and mobile.

Knowing the pixel sizes is half the battle. Here's what separates designs that get engagement from designs that don't.
Go vertical for reach
Portrait 1080x1350 takes up the most screen in the feed. LinkedIn is a scroll of gray and white, so surface area is attention.
Design text graphics like slides
Short, bold statements in big type outperform dense graphics. If it can't be read in two seconds, simplify it.
Upload video natively
Native video autoplays in the feed and reaches significantly more people than external video links. Keep it under 90 seconds.
Keep contrast high
The LinkedIn feed is light gray. A bold color block in your brand palette stops the scroll where a pale graphic disappears.
