Will an iPhone 17 Pro case fit an iPhone 18 Pro?

The short answer

Apple’s spec pages give the iPhone 18 Pro exactly the same height, width and depth as the 17 Pro (150 mm × 71.9 mm × 8.75 mm), and the same is true of the 18 Pro Max and 17 Pro Max (163.4 mm × 78 mm × 8.75 mm).

Matching outlines don’t prove a case fits: the camera opening, button cut-outs and microphone holes have to line up too, and those aren’t in a dimensions table. Apple sells separate cases for each and lists one model on each case. We cut our cases for one model as well, so choose the one for the phone you own.

Side by side

Official dimensions from the manufacturer. Dimensions alone don’t decide fit: camera position, button placement and cut-outs matter just as much.

What actually changes between them

These are the differences a case has to follow. Any one of them is enough to stop a case sitting flat, covering a button or lining up with the camera.

• Apple lists exactly the same height, width and depth for both

iPhone 16e and iPhone 17e

The same caution applies here. Apple lists both at 146.7 mm × 71.5 mm × 7.8 mm, but the 17e adds MagSafe, which the 16e doesn’t have. If you use MagSafe chargers or wallets on a 17e, pick a MagSafe case made for it.

Why “almost fits” isn’t good enough

A case that nearly fits can press a side button all the time, leave a gap at one corner where the phone can pop out when dropped, or sit on the camera rim so the lenses touch the table. A raised edge around the camera only protects if it surrounds the lenses exactly.

Every YOONIG case is cut for one model, so the print, the openings and the raised edges line up with that phone. If you are not sure which model you have, our guide to finding your exact model takes a minute.
