Anyone know what dimensions each should have?

This is fun, all of these were done with Midjourney, aspect ratio of 16:9, prompts at bottom

Prompts were

• dieselpunk, a diesel engine spider attached to an enormous industrial building of another, in the style of meticulous military scenes, otherworldly design, muted earth tones, manticore, 8k, emphasis on detail
• Dieselpunk, an illustration of the main character of the game, dieselpunk soldier, intricate gas mask, in the style of light brown and dust, ivan albright, ps1 graphics, soldier art, intense action scenes, kevin hill, animated mosaics, pollution
• dieselpunk, an illustration of the diesel airship from the game, blimp, in the style of light brown and dust, ivan albright, ps1 graphics, soldier art, intense action scenes, kevin hill, animated mosaics, pollution

I really loved this prompt, here are some other ones it came up with ->
