What cases fit my iPhone? A model-by-model fit guide
Can you keep your old case when you upgrade? Every recent iPhone pair checked against Apple’s official specs, plus Galaxy S and Pixel, with a plain yes or no.

The short answer
Almost never. Across every pair we checked, no two phones are confirmed to share a case. Most differ in at least one official dimension, or in the port or side buttons, and that alone rules a case out.
A few pairs have identical official dimensions: iPhone 16e and iPhone 17e; iPhone 17 Pro and iPhone 18 Pro; iPhone 17 Pro Max and iPhone 18 Pro Max; Galaxy S25+ and Galaxy S26+; Pixel 9 Pro XL and Pixel 10 Pro XL. Even there, a matching outline doesn’t prove the camera opening and button cut-outs line up, and makers sell separate cases for each. Apple, for instance, lists a single model under compatibility on its own cases.
How we decide
We only use official figures from Apple, Samsung and Google: height, width and depth, charging port, side buttons and magnets. Any difference in those is a “No”. Identical figures get “Not confirmed”, unless one of our detailed fit guides already found a difference such as the camera module. If we couldn’t back a verdict with the specs, we left the pair out.
Every pair works the same in both directions: if a 15 case doesn’t fit a 16, a 16 case doesn’t fit a 15 either.

Frequently asked questions
Will my old iPhone case fit my new iPhone?
For every recent pair we checked, the answer is no or not confirmed. Each new model changes size, the port or the buttons, so buy a case made for the phone you have.
Do iPhone 13 and 14 cases fit each other?
No. They share height and width, but the iPhone 14 is 7.8 mm deep against 7.65 mm.
Are iPhone 15 and 16 cases the same?
No. Apple lists the same dimensions, but the iPhone 16 adds an Action button and Camera Control, which need their own openings.
Can I use a 17 Pro case on an 18 Pro?
Not confirmed. The official dimensions are identical, but Apple sells separate cases for each and lists one model on each case. Choose the case for your exact model.
Will a Galaxy S25 case fit an S26?
No. The S26 is 149.6 × 71.7 × 7.2 mm against 146.9 × 70.5 × 7.2 mm for the S25.
Does a bigger case work on a smaller phone?
It goes on, but it’s loose: the phone can slip out in a drop and the openings sit in the wrong places. A case made for your exact model is the safe choice.
