iPhone 16 vs iPhone 17
2.0 mm taller, 0.15 mm thicker and 7 g heavier.
Quick answer
Choosing between iPhone 16 and iPhone 17 comes down to wanting a larger display without increasing overall footprint. iPhone 17 expands the screen to 6.3 inches compared to 6.1 inches on iPhone 16, achieved largely through slimmer bezels. iPhone 17 measures 149.6 mm tall and 71.5 mm wide, while iPhone 16 measures 147.6 mm tall and 71.6 mm wide. In hand, the grip feel is virtually identical because the widths match within a fraction of a millimeter. iPhone 17 weighs 177 g, which adds 7 g over the 170 g iPhone 16. Neither phone fits into median women's jeans pockets, but both fit into median men's jeans pockets. The size change alone does not demand an upgrade.
- Identical widths make iPhone 17 feel just as comfortable to grip as iPhone 16.
- iPhone 17 provides a 6.3 inches screen while adding only 7 g of weight.
- Both models fit median men's pockets, but neither fits median women's jeans pockets.
- Upgrading solely for physical dimensions is unnecessary given the subtle 2 mm height difference.
