Sticking to 1.91:1 means your image maps onto the preview card with no cropping or side bars. X prefers a slightly taller 16:9 (1200x675) for its timeline, but it scales the universal 1.91:1 image cleanly, so one 1200x630 file is the safe cross-platform choice.
Common mistake: A frequent mistake is designing at 16:9 (1.78:1) and assuming it is the same as OG. It is not: a 16:9 image gets letterboxed or trimmed inside a 1.91:1 card. Crop to a true 1.91:1 so the card fills correctly.
