Irrespective of the network, all iPhone 6 models feature a 4.7-inch (diagonal) widescreen multi-touch IPS LED-backlit "Retina HD" display with a 1334x750 resolution (326 ppi).

Initially, the iPhone 6 was available in three metallic finishes: "silver" with a white front and silver aluminum back; "gold" with a white front and gold aluminum back; and "space" gray with a black front and medium-gray aluminum back. The re-introduced 32 GB model was only offered in gold for China and Taiwan, and in "space" gray for India, Europe, and the US (on Boost Mobile). All models share a "unibody" design with smoothly rounded sides, reminiscent of the 5th Gen iPod touch, and feature a glass front that curves at the edges for a continuous surface. The "Touch ID" fingerprint sensor is embedded in the home button.
