Image Sizes

Image size and aspect-ratio guidance for social media — the exact dimensions that work best on each platform, why images get cropped unpredictably when the wrong ratio is used, and how to build one master image that survives being distributed to several destinations from a single RSS feed. Posts here are the practical reference for anyone whose automated posts include images, covering both platform-specific size charts and the underlying safe-zone principles that keep a single image looking intentional everywhere it lands. Vertical video gets its own article, since reels and shorts follow different rules from still images and not every destination accepts them. The practical conclusion in both is to design one master image with a safe centre area rather than maintaining a version per network. Feeds that supply no image at all are covered too, because what a destination does in that case varies.
