Crop-to-Aspect Calculator
Find the largest crop of a given raster that hits a target aspect ratio, with the exact pixels removed from each pair of edges.
Reframing 16:9 UHD to 9:16 vertical keeps the full 2160 height and crops to 1215 wide — losing 1312 px split across left and right, which is why you must reposition the subject, not just center-crop. This gives the exact target raster and trim so your pan-and-scan keys land precisely.
