       Introduction to iPhone 7 Screen OverviewApple's iPhone 7, launched in 2016, revolutionized mobile displays with its compact yet powerful screen. The device features a 4.7-inch Retina HD display, a staple in Apple's lineup that balances portability and functionality.

       Exact Size Dimensions and Physical AttributesThe iPhone 7 screen measures precisely 4.7 inches diagonally, with a width of 2.32 inches and height of 4.09 inches, as documented on Apple's product details page. This compact form factor contributes to a sleek profile, weighing just 138 grams. As a case in point, Apple's design team emphasized this in their 2016 keynote, highlighting how it fits comfortably in smaller hands.
