All iPhone 6 Plus models (sometimes called iPhone 6+ by users), regardless of network support, feature a 5.5-inch (diagonal) widescreen multi-touch IPS LED-backlit "Retina HD" display with a 1920x1080 resolution (401 ppi).

The iPhone 6 Plus was sold in three metallic finishes: "silver" (white front, silver back), "gold" (white front, gold back), and "space" gray (black front, medium gray back). Each model has a "unibody" design with rounded sides, similar to the 5th Gen iPod touch, but with glass that curves at the edges for a seamless feel. It also includes the "Touch ID" fingerprint sensor in the home button.
