LinkedIn ad size: single image 1200 x 628 and more
LinkedIn's ad specifications recommend single image ads at 1200 by 628 pixels for horizontal 1.91:1, 1200 by 1200 for square and 720 by 900 for vertical 4:5. Images can be JPG, PNG or GIF up to 5 MB, and vertical images serve on mobile only. Introductory text shows 150 characters before it is cut.
LinkedIn runs most sponsored content as a single image above a headline, in a feed read on desktops more than on any other social network. Its specification page gives a recommended, minimum and maximum size for each shape.

Three shapes and when to use each
The horizontal 1.91:1 image at 1200 by 628 is the classic LinkedIn shape and the one shown on desktop. Square at 1200 by 1200 takes more height in the feed and works on both desktop and phone. Vertical 4:5 at 720 by 900 is recommended by LinkedIn but, as its help page notes, vertical assets serve only on mobile, and a 1.91:1 vertical image gets borders on each side. If a campaign runs everywhere, horizontal or square is the safe choice.
1200 x 627 or 1200 x 628
LinkedIn's organic post guidance gives link images as 1200 by 627, and its ad specification gives 1200 by 628. The one pixel difference does not matter: both are 1.91:1, and LinkedIn scales either to the same display box. What matters more is the minimum: a horizontal ad below 640 by 360, or any image narrower than 401 pixels, is shown as a small thumbnail instead of a full width image.
Text on the image and in the fields
The ad's introductory text is cut after about 150 characters and the headline after about 70, so the message has to land early in both fields. Text in the image should support those fields, not repeat them: a figure, a short claim, or a product view. B2B audiences on LinkedIn read on desktop more often than on other networks, so an image with a little more detail is acceptable, but it must still read on a phone.
Common mistakes
Uploading a vertical image for a desktop heavy audience and losing reach on desktop. Using a small image that LinkedIn shows as a thumbnail. Writing the whole offer into a 1200 by 628 image in small type. Exceeding the 5 MB limit with an uncompressed PNG photo. And reusing a Facebook ad with Facebook specific wording such as a Like prompt.
Making LinkedIn ad images
The flyer editor's LinkedIn Post canvas is 1200 by 627, the 1.91:1 shape LinkedIn uses for single image ads, so the editor makes this size directly: choose LinkedIn Post under Format in the generator and export a PNG or JPG, which comes out at 2400 by 1254, inside LinkedIn's maximum. Its Instagram Post canvas, 1080 by 1080, covers the square shape. The editor has no 4:5 canvas; the flyer size resizer refits a design to 720 by 900 when a mobile only vertical ad is wanted.
Questions people ask
Can a LinkedIn ad be an animated GIF?
Yes. LinkedIn's single image ad specification accepts GIF, and animated GIFs must be 250 frames or shorter within the 5 MB file limit. Keep the first frame meaningful, since that is what shows before the animation loads and what some readers see if the GIF does not play.
Does LinkedIn crop ad images?
LinkedIn fits the image to the chosen shape. A 1.91:1 image placed in a vertical ad gets borders on each side, and a very small image is shown as a thumbnail. Uploading the recommended size for the shape avoids both and keeps text sharp.
Is the LinkedIn ad size the same as a post image?
The shapes match: LinkedIn's help page gives organic link images at 1200 by 627 and ads at 1200 by 628, both 1.91:1. The same artwork can be used for both, though ads have their own text fields and character limits.
What is the best LinkedIn ad size for mobile?
Square at 1200 by 1200 takes the most space on a phone while still serving on desktop, so it is the usual choice for a mixed audience. Vertical 720 by 900 is taller but serves on mobile only, so it suits campaigns aimed at people reading on their phones, such as event promotion or recruitment.
Should a LinkedIn ad show people or the product?
Either can work; the test is whether the image explains the offer in a second. A product screen suits software and tools, a photo of a person at work suits services and hiring. Avoid generic stock handshakes, which are common on LinkedIn and easy to scroll past. Whatever the subject, keep it clear of the lower corners where the logo and text sit.
How long should LinkedIn ad text be?
Keep the introductory text near 150 characters and the headline near 70, which is where LinkedIn truncates. The maximums are 3,000 and 200 characters, but anything past the cut sits behind a See more link most people never click, so lead with the benefit.
