A case is cut for one model, and two iPhones with the same screen size can still need different ones. Start from your phone.

Which iPhone do I have?

The sure way: open Settings, then General, then About, and read the Model Name line. The quick way: turn the phone over and look at the cameras.

Will a case for one model fit another?

Almost never. The iPhone 17 and 17 Pro are both 6.3 inches and still take different cases, because the Pro's camera bar sits where the 17 has a vertical pair. A case cut for the wrong one either will not close or leaves a lens half covered.

The exceptions are shared sizes a maker states outright, and even those are the maker's claim rather than Apple's. We checked the most common one in Will iPhone 17 cases fit the iPhone 18 Pro?

Magnetic accessories are the opposite: a MagSafe wallet, charger or mount fits every iPhone with the magnet ring, which is every model here except the iPhone 16e.
