Size matters not.

That said, let's have an iPhone-measuring contest. First, It's SE 2016 vs SE 2020 in a matchup no one was expecting.

The new SE wins the measuring contest, but the 2016 SE wins the headphone jack contest by a mile.

This phone has been called an iPhone 8 (black) with the innards of an iPhone 11 (green). We'll see about that.

The new SE is only slightly smaller than the 11 Pro, but what you really notice is the weight difference—the SE is 21% lighter than the 11 Pro.
