The recommended LinkedIn ad format is 1200 x 627 pixels (aspect ratio 1.91:1). This is not only the format for the images in the most commonly used LinkedIn ‘Single Image’ ads but also for so-called ‘Promoted Posts’. To ensure your advertisement is always sharp, we recommend using 2400 x 1254 pixels for your image.
LinkedIn ads come in many different shapes and sizes. Sometimes it takes a bit of searching to find the correct resolution for your image. LinkedIn has determined minimum and optimal ad formats for each type of advertisement. We have listed them for you:
Important: read everything about LinkedIn ad campaigns and their structure on our page LinkedIn advertising. On this page, we share best practices and tell you which ads are optimal for your campaign.
The recommended ad format for Single Image Ads is 1200 x 627 pixels. This is an aspect ratio of 1.91:1 and is used to display ads on both desktop and mobile. LinkedIn also offers the possibility to use square images (1:1 aspect ratio), or a 1:1.91 ratio used exclusively for mobile.
Can you use images smaller than 1200 x 627 pixels? Yes, LinkedIn maintains a minimum of 360 pixels, making a square image of 360 x 360 the smallest image you can use in your LinkedIn ad. However, this is not recommended; your image will quickly look low-quality, which can come across as unprofessional.
Can you use larger images? That is no problem either; 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. Note that your image cannot exceed 5 MB, as the platform will not accept larger files.
The specifications for LinkedIn Video ads are very similar to those of Single Image ads. The minimum number of pixels is 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 monitors and TVs—a 640 x 360 pixel video is the minimum. The popular ‘short’ format seen on TikTok and YouTube has an alternative aspect ratio of 4:5 and must be at least 360 x 450 pixels. It is also possible to use a different portrait aspect ratio; the 9:16 ratio requires 360 x 640 pixels.
However, low pixel counts result in low-quality video and likely poorer results. What is the ideal resolution for your video? The standard widescreen resolution of 1920 x 1080 pixels is optimal for LinkedIn and ensures a sharp image on all devices. This is also the maximum resolution for this aspect ratio.
Applying this maximum to the aspect ratios mentioned earlier results in a maximum resolution of 1920 x 1920 for square videos. With 1080 x 1350 for the recommended vertical 4:5 aspect ratio and the alternative 9:16 aspect ratio at 1080 x 1920 pixels, the resolutions are complete.
A video can be a maximum of 500 MB; LinkedIn will not accept anything higher. Using the H.264 or VP8 codec, you can still upload long videos; LinkedIn states a maximum of 30 minutes. However, the best-performing videos last between 15 and 30 second—the algorithm is designed for this.
For video, there is another aspect: the thumbnail. This must have the same aspect ratio and resolution as the video and can be a maximum of 2 MB in size.
Carousel ads present a series of square images as cards that users can click through. LinkedIn uses the same specifications here as for square Single Image Ads: 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 indicates that the total maximum size of all Carousel Ad cards combined is 10 MB.
The dimensions of the logo displayed with LinkedIn Text Ads can be a maximum of 100 x 100 pixels.
LinkedIn Text Ads are an option provided by LinkedIn to place a very short message in the platform’s sidebar, comparable to a Google Search ad.
