The sizes will depend on the number of images you want to use:
1 image → 792 × 400 px
2 images → 653 × 400 px (each)
3 images → 430 × 400 px (each)
5 images → 3 images at 430 × 400 px + 2 images at 653 × 400 px
6 images → 430 × 400 px (each)
7 images → 430 × 400 px (each)
Key point: always keep the height at 400 px. That's what ensures a clean crop and that all images look balanced.
