Shapes that have stayed stable
Recommended pixel sizes change often, but the underlying shapes have been steady: 1:1 squares, 4:5 portrait posts, 16:9 landscape video and link cards around 1.91:1, and 9:16 for stories and short video. Crop to the shape first, then resize to the platform's current recommended width.
For stories and reels, keep text and faces away from the top and bottom of the frame, where profile names, captions and buttons are drawn over the image.
More on why crops go wrong, and how much of a photo each shape keeps, in aspect ratios and bad crops.
Questions people ask

4:5, typically 1080 × 1350 px.
Do social networks remove location data?
Many large ones strip it from public posts, but not every platform or sharing route does. Removing it yourself is the reliable option.
How do I post a panorama as a carousel?
Crop it to 3:1, then split it into one row of three squares.
