Is the standard photo size 3: 2 or 4: 3?

Of course, the ratio is 3:2! ..

Just like the best film is 1.85: 1 or the ratio of pure film camera is 2.35: 1-2.40: 1. ...

For example, Jackie Chan's movies. Or the proportion of movies made in Hollywood, USA! ...

These are the most suitable proportions for human eyes to watch ... especially 2.35: 1. ....

I hope I can help you! ..

Good luck! ....
