The iPhone screen size varies depending on the iPhone model you own. Let's breakdown the various models in terms of the diagonal screen measurement for each one.

The first generation iPhone, iPhone 3G, and iPhone 3GS all share the same 3.5" screen (89mm) with a 480x320 pixel resolution.

The iPhone 4 and iPhone 4S also have a 3.5" screen (89mm) except instead have a 960x640 pixel resolution, twice as dense as the earlier models.

The iPhone 5, iPhone 5C, iPhone 5S, and iPhone SE were the first iPhones to have an increased screen size, measuring 4" diagonally (100mm) with an 1136x640 pixel resolution.

A 4.7" (120mm) screen was introduced with the iPhone 6 and continues in the iPhone 6S, iPhone 7, and iPhone 8. This screen offers a 1334x750 screen resolution.

The iPhone 6 Plus, iPhone 6S Plus, iPhone 7 Plus, and iPhone 8 Plus all sport a 5.5" (140mm) screen that packs in a 1920x1080 pixel resolution.

In 2017, the iPhone X was released with a whopping 5.8" (150mm) diagonal screen and a 2436x1125 screen resolution, providing our 32% more pixels that the previous generation iPhone.

Three new iPhone models were introduced in late 2018. The iPhone Xs has the same 5.8" (150mm) diagonal screen and 2436x1125 screen resolution as the iPhone X while the iPhone Xs Max sports a 6.5" (165mm) screen with a 2688x1242 resolution. The 6.1" (155mm) iPhone Xr has a 1792x828 pixel resolution.
