The LinkedIn Event Banner size (1776×888px)
When you create an event on LinkedIn, the banner is the wide image that headlines the event page and appears in the feed whenever the event is shared. LinkedIn recommends a 1776x888 pixel image, a clean 2:1 landscape shape, and uploading at this size fills the header band without the softness that appears when a smaller file is scaled up to fit.
The main consideration is legibility in a professional feed. LinkedIn event banners frequently carry the event name, date, and speaker names, and they are viewed at a reduced size in the feed before anyone opens the full page. Keeping the essential details, the title and date, within the central area and using type large enough to survive that feed-size reduction ensures your banner still communicates when it is only a few hundred pixels wide on someone's timeline.
Designing at the native 2:1 ratio also prevents the awkward crop that occurs if you reuse a square graphic or a differently proportioned poster. Because event promotion often means several shares, a banner that reads clearly at both full and reduced sizes keeps your messaging consistent everywhere it lands. This tool resizes 100% in your browser with no upload, it is free, and it keeps the 2:1 aspect ratio locked. LinkedIn adjusts its event and page layouts over time, so verify the current recommended size before you launch registration.
