What the difference feels like

The two are within 0.4 mm of each other in width, which is the measurement your grip notices most, so they should feel close to the same in the hand.

Height is almost identical, so they sit the same in a pocket.

The iPhone 18 Pro is 0.5 mm thicker. Manufacturers measure thickness without the camera bump, so the real difference at the camera can be larger.

The iPhone 18 Pro is 12 g heavier, which most people will not notice day to day.
