What the size difference means in daily use
One-handed use

Pockets and bags
iPhone Air is 6.2 mm taller, which mostly affects how deep it sits in a pocket and how far your thumb must stretch to the top edge. iPhone 17 Pro is noticeably thicker, by 3.11 mm, which you may feel in a slim pocket.
Cases and screen protectors
Because the height or width differs by about a millimetre or more, a case or screen protector made for iPhone Air is unlikely to fit iPhone 17 Pro. Always buy accessories listed for the exact model.
