LinkedIn paid ad specs

The recommended LinkedIn paid ad specs is 1200 x 627 pixels (aspect ratio 1.91:1). This is not only the image size for the most commonly used LinkedIn ‘Single Image’ ads, but also for the so-called ‘Promoted Post’. To ensure a crisp ad, we recommend using an image size of 2400 x 1254 pixels for your ad.

LinkedIn paid ad specs

LinkedIn ads come in many different shapes and sizes. So, sometimes it takes a bit of searching to find the right resolution for your image. LinkedIn has set both minimum and optimal ad specs for each ad type. Here’s a breakdown for you:

  • LinkedIn Single Image Ads
  • LinkedIn Video Ads
  • LinkedIn Carousel Ads
  • LinkedIn Text Ads

Important: Read our page LinkedIn Advertising to learn everything about LinkedIn ad campaigns and their structure. On this page, we share best practices and tell you which ads are optimal for your campaign.

LinkedIn Single Image Ads specs

The recommended ad specs for Single Image Ads is 1200 x 627 pixels. This is an aspect ratio of 1.91:1, and it is used to display ads on both desktop and mobile. LinkedIn also offers the option to use square images (aspect ratio 1:1) or a 1:1.91 ratio that is exclusively for mobile.
Can you use images smaller than 1200 x 627 pixels? Yes, LinkedIn has a minimum of 360 pixels, so a square image of 360 x 360 pixels is the smallest image you can use in your LinkedIn ad. However, this is not recommended, as your image will quickly look poor and may come across as unprofessional.

Can you use larger images? That’s also no problem; the maximum number of pixels for a LinkedIn ad is 7680 wide by 4320 high for a horizontal ad. A square image has the same maximum of 4320 pixels, which is also the maximum height for a vertical ad. However, make sure your image size does not exceed 5 MB, as the platform will not accept larger files.

LinkedIn Video Ads specs

The specifications for LinkedIn Video Ads are quite similar to those of Single Image Ads. The minimum number of pixels is also 360, so you can upload videos with a 1:1 aspect ratio at a resolution of 360 x 360 pixels. If you want to show a horizontal video, commonly used for screens and TVs, a minimum resolution of 640 x 360 pixels is required. The popular ‘short’ format seen on TikTok and YouTube has an alternative aspect ratio of 4:5, which must be at least 360 x 450 pixels. It’s also possible to use another vertical aspect ratio, with the 9:16 aspect ratio requiring 360 x 640 pixels.
However, fewer pixels result in lower video quality and likely poorer performance. What is the ideal resolution for your video? The standard widescreen resolution of 1920 x 1080 pixels is optimal for LinkedIn and ensures sharp images on all devices. This is also the maximum resolution for this aspect ratio.

Apply this maximum to the aspect ratios we mentioned earlier, and you get a maximum resolution of 1920 x 1920 for square videos. With 1080 x 1350 for the recommended vertical aspect ratio of 4:5, and the alternative 9:16 aspect ratio with 1080 x 1920 pixels, we’ve covered all the resolutions.

A video file can be up to 500 MB, with LinkedIn not accepting anything larger. This still allows you to upload long videos, thanks to the H.264 or VP8 codec. The maximum length LinkedIn accepts is 30 minutes. However, the best-performing videos are between 15 and 30 seconds long, as this is what the algorithm favors.

There’s another aspect to videos: the thumbnail. It must have the same aspect ratio and resolution as the video and must be no larger than 2 MB.

LinkedIn Carousel Ads specs

Carousel ads present a series of square images as cards that users can click through. LinkedIn uses the same specifications as for square Single Image Ads, namely a minimum of 360 x 360 pixels and a maximum of 4320 x 4320 pixels. We recommend using at least 1200 x 1200 but preferably 2400 x 2400 pixels. LinkedIn states that the maximum total size for all Carousel Ad cards combined is 10 MB.

LinkedIn Text Ads

The logo size displayed with LinkedIn Text Ads can be a maximum of 100 x 100 pixels.
LinkedIn Text Ads are an option LinkedIn provides for placing very short messages in the sidebar of the platform, similar to a Google Search ad.
