LinkedIn is one of the few platforms where image optimization still matters for reach. In 2026, the algorithm favors properly sized images that load quickly and look sharp on high-DPI displays.
The recommended size for single image posts is 1200 x 627 pixels (1.91:1 ratio). This is the same ratio used for link previews and ensures your image displays fully without cropping.
For carousel posts (PDF documents), use 1080 x 1350 pixels (4:5 ratio) or 1080 x 1080 pixels (1:1 square). Carousels get 2-3x more engagement than single images.
LinkedIn video thumbnails should be 1280 x 720 pixels (16:9 ratio) for the best appearance in feeds and on video pages.
1200 x 627 pixels for single images, 1080 x 1350 for carousels.
Yes. Upload at 80-90% quality to avoid double compression artifacts.
