Otterbox and Astropad expect iPhone 17 Pro cases to fit iPhone 18 Pro despite conflicting thickness leaks
↗
Otterbox is already selling cases at Best Buy labeled compatible with both iPhone 17 Pro and iPhone 18 Pro, and Astropad says its suppliers confirm matching dimensions, though other leaked specifications suggest the newer model could be thicker.
If the two Pro models share dimensions, users can retain cases across upgrades and accessory makers avoid redesigns. Conflicting leaks about a roughly 2mm thickness increase introduce real risk that companies betting on compatibility may face returns and reputational damage if wrong.

Otterbox cases on sale at Best Buy carry packaging explicitly listing compatibility with both iPhone 17 Pro and iPhone 18 Pro.
Astropad's Matt Ronge says his suppliers confirm the same dimensions for both models.
Leaked supplier materials indicate the iPhone 18 Pro could be roughly 2mm thicker than its predecessor, while at least one leaker claims the Pro Max thickness is unchanged.
