Three shapes, and one of them is mobile only

LinkedIn single image ads come in three shapes: landscape 1.91:1, square 1:1 and vertical 4:5. Landscape and square appear on both desktop and mobile. Vertical images are served on mobile only, so they should never be the only version you upload.

Carousel ads use square cards. The table below lists each one with the size to make.

Choosing between them

  • Square is the best all-rounder

    It runs on every device and takes up more of a phone screen than landscape. If you can make only one LinkedIn image, make the square.

  • Pair vertical with a second size

    Because vertical images do not serve on desktop, a campaign with only a 4:5 creative misses everyone at a computer, which on LinkedIn is a large share of the audience.

  • Small text disappears

    Feed images are shown well below their full size, particularly on desktop. Text that reads clearly at 1200 pixels wide can be illegible in the feed, so keep it large and brief.

Your images stay on your device.
