The iPhone XS retains the familiar design of the iPhone X, including a 5.8-inch OLED display and stainless-steel sides. Apple also offers a larger version of the XS with a 6.5-inch OLED display called the iPhone XS Max. With a footprint about the same size as the iPhone 8 Plus, the iPhone XS Max has the largest display found on any iPhone.

The iPhone XS and XS Max come in silver, space gray and gold. Apple opted for more of a straw-colored gold this time than for previous gold iPhone models.
