The iPhone 16 Pro and iPhone 16 Pro Max are expected to have slightly larger dimensions compared to their predecessors, the iPhone 15 Pro and iPhone 15 Pro Max. According to leaked information, the iPhone 16 Pro will have a height of 149.6 mm (up from 146.6 mm), a width of 71.45 mm (up from 70.60 mm), and a thickness of 8.25 mm (no change). The iPhone 16 Pro Max will have a height of 163.0 mm (up from 159.9 mm), a width of 77.58 mm (up from 76.70 mm), and a thickness of 8.26 mm (up from 8.25 mm).
In terms of screen size, the iPhone 16 Pro will have a 6.3-inch display (up from 6.1 inches), and the iPhone 16 Pro Max will have a 6.9-inch display (up from 6.7 inches). Additionally, the screen borders on the iPhone 16 Pro models will be reduced, with the iPhone 16 Pro having a 1.2 mm border (down from 1.71 mm) and the Pro Max having a 1.15 mm border (down from 1.55 mm).
These changes make the new models slightly larger and heavier than their predecessors, with the iPhone 16 Pro weighing 194 grams (up from 187 grams) and the iPhone 16 Pro Max weighing 225 grams (up from 221 grams).

The screen border size in the new iPhone 16 Pro models has significantly reduced compared to the previous iPhone 15 Pro models. The iPhone 16 Pro has a screen border of 1.2 mm, down from 1.71 mm in the iPhone 15 Pro, which is a 30% reduction. On the other hand, the iPhone 16 Pro Max has a border of 1.15 mm, down from 1.55 mm in the iPhone 15 Pro Max, which is a 26% reduction. These reductions are attributed to Apple's adoption of the Border Reduction Structure (BRS) technology, allowing for a more compact and efficient layout of the circuitry under the display, resulting in even slimmer bezels.

Apple is using Border Reduction Structure (BRS) technology in the iPhone 16 series to achieve reduced bezel sizes. This technology allows for a more compact and efficient layout of the circuitry under the display, resulting in even slimmer bezels.
