iPhone 15 Pro Max dimensions at a glance
The table lists Apple’s official measurements in metric and imperial units. Length here means the height of the phone, from the top edge to the bottom edge.

| Width | 76.7 mm (7.67 cm) | 3.02 in |

How long is the iPhone 15 Pro Max compared with its screen size?
The 6.7-inch label refers to the display, not the body. Apple measures screen size on the diagonal, from one corner of the panel to the opposite corner.
The body is 6.29 inches tall, which is less than the 6.7-inch screen figure. A diagonal line across a rectangle is always longer than its height, so the two numbers do not match.
The display has rounded corners. Measured as a standard rectangle, Apple says the screen is 6.69 inches on the diagonal. It runs at 2796 by 1290 pixels, at 460 pixels per inch.
