Complete screen size guide for the iPhone 17 with 6.3" display
Last updated: Apr 2026
Expert Summary: Apple finally brings 90Hz to the base iPhone after years of user complaints about 60Hz.

Worth upgrading from iPhone 13 or older; iPhone 15/16 users should weigh whether 90Hz alone justifies the cost.
Scenario Decision Guide

Should You Choose iPhone 17?
A quick editorial check for the real-world trade-offs behind this screen size.
Choose it if
- You want the newest standard iPhone size without moving into a heavy Pro Max body.
- You care more about smoother daily scrolling and long software support than maximum camera hardware.
- You are upgrading from an iPhone 13, iPhone 14, or older 6.1-inch phone and want a familiar but slightly roomier screen.
Skip it if
- You already use an iPhone 15 or iPhone 16 and only care about screen size, because the physical jump is modest.
- You need the best battery headroom Apple offers, where the Pro Max body still makes more sense.
- You want the thinnest pocket feel possible and are willing to accept smaller battery capacity.
Bottom line: Choose iPhone 17 if you want the safest current iPhone size: modern, manageable, and large enough without becoming a two-hand phone.
