A new listing from the case manufacturer Spigen has potentially revealed the display size for the upcoming iPhone 17. According to the description of one of its screen protectors on Amazon India, the accessory is compatible with the iPhone 16 Pro, iPhone 17, and iPhone 17 Pro, all of which are said to feature 6.3-inch displays. This aligns with earlier rumors from May suggesting that the iPhone 17 will have a slight screen size increase from the iPhone 16’s 6.1-inch display. 
If accurate, this change would bring the standard iPhone closer to the Pro model in terms of screen size, although differences in display quality are still expected.
The iPhone 16 lineup currently offers a 6.1-inch display on the base model, 6.3 inches on the Pro, 6.7 inches on the Plus, and 6.9 inches on the Pro Max
. Based on current information, both the iPhone 17 and iPhone 17 Pro will sport 6.3-inch screens, with the Pro Max likely keeping its 6.9-inch display. A new model, possibly dubbed the iPhone 17 Air, could replace the Plus variant with a 6.6-inch display.
While the size might match between the iPhone 17 and iPhone 17 Pro, the Pro model will likely feature a superior display panel, with higher refresh rates and brighter capabilities reserved for the more expensive versions. This means that, despite the size similarity, users can expect a different experience in terms of screen quality.
How users feel about the change will likely vary. A 6.3-inch display could offer a sweet spot for those desiring more screen real estate without going overboard. However, those who prefer more compact devices might not welcome the size increase. From our perspective, smaller screens are easier to use one-handed and more pocket-friendly, so the adjustment to a larger size might take some getting used to.
This potential change could reflect Apple’s ongoing effort to bring more consistency across its iPhone models. Case manufacturers like Spigen sometimes release this kind of detail before Apple makes its official announcement, so we’ll have to wait for confirmation later this year to know for sure.
