Dimensions of the box

The iPhone 12 Pro and iPhone 12 will have the same size box.

For the Pro Max and Mini, you'll need to search for them. There is no apple document that specifies the dimensions of the actual box. And unless someone has taken the time to measure them, it will be hard to find.

Start here. Find each product and examine its tech specs.

Your post’s title mentioned the box. However, the body of your post inquired about the actual device sizes.
