Tips for this size
Portrait posts take up the most room in the feed, which usually helps them get noticed.
Upload at the exact size where you can, because platforms recompress images and resizing twice softens them. If your image has a different shape, it will be cropped or padded. The Image Resizer lets you choose, and everything runs in your browser. Work out other dimensions with the Aspect Ratio Calculator.
