The iPhone XS Max also has a 6.5 inch diagonal display, but it has a height of 6.20 inches and a width of 3.05 inches.
The first several generations of iPhone had screens measuring just 3.5 inches diagonally and would seem positively miniature today.

When I first got my iPhone 8 Plus, I had been using an iPhone 6 for nearly two years. The iPhone 8 Plus felt gigantic in my hand and in my pocket, and I thought I'd never get used to it.

But within a matter of days, my wife's iPhone 7 felt miniature and the iPhone 8 Plus totally natural. Now she has an iPhone 11, and I think Apple may have hit the sweet spot, size-wise. The iPhone 11 has a 6.1 inch screen.

But for the biggest iPhone screen around, you need to go a bit past the iPhone 11 and get an iPhone 11 Pro Max, which has a screen that's 6.5 inches on the diagonal. This length ties the iPhone XS Max in diagonal display, but the iPhone 11 Pro Max measures 6.22 inches tall and is 3.06 inches wide compared to the iPhone XS Max's 6.20 inch height and 3.05 inch width.

If that's a bit large for you but you still want crazy good processing power and cameras, the iPhone 11 Pro has a 5.8 inch screen measured on the diagonal, and it still has the same processing power, display clarity, and those three cameras that the mighty iPhone 11 Pro Max boasts.
