The LinkedIn Image & Video Size Cheatsheet is a single reference for every official LinkedIn image and video dimension, so you never have to guess whether a banner is 4:1 or a post image should be square. Wrong sizes get cropped, stretched, or letterboxed, which looks unprofessional on a network built around personal brand.
How it works
Each LinkedIn surface has a recommended resolution and aspect ratio defined by the platform. The cheatsheet groups them by category — profile, company page, posts, and ads — and lists the target pixels, ratio, and accepted formats for each. Filter to your category and match your canvas to the listed numbers before export.
Tips and notes
The most commonly mis-sized asset is the profile banner (1584 x 396, 4:1) because the lower-left corner is covered by your photo and headline — keep important content centred or to the right. Square feed images (1080 x 1080) consume more vertical screen space than landscape (1200 x 627), so they tend to stop the scroll. For video, LinkedIn supports 1:1, 16:9, and vertical 9:16; vertical performs best on mobile. Always export at the listed resolution or a clean 2x multiple to stay sharp on high-density displays.
