Every year, Apple makes subtle design changes to its latest iPhones, which means cases from previous models don't always fit the new ones. This brings up a common question: will an iPhone 14 Pro Max case fit an iPhone 15 Pro Max?
While the two devices look similar, key differences in size, button placement, and design mean that an old case won't provide the snug, secure fit needed for proper protection.
The iPhone 15 Pro Max is slightly smaller, features a new contoured edge design, and replaces the mute switch with the Action Button—all of which impact case compatibility. We've put it to the test and gathered the details, so if you're wondering whether to reuse an old case or invest in a new one, here's everything you need to know.

Will An iPhone 14 Pro Max Case Fit an iPhone 15 Pro Max?
Let's get straight to the point: No, an iPhone 14 Pro Max case will not properly fit the iPhone 15 Pro Max. It's a similar issue to asking will iPhone 14 case fit iPhone 15 or will iPhone 13 case fit iPhone 15?
At first glance, the two phones look similar, but Apple has made key changes that prevent an old case from fitting snugly on the new model. Here's why:
- Size Differences: According to our research, the iPhone 15 Pro Max is slightly smaller than the 14 Pro Max. It's a tiny bit shorter and narrower, but thicker than its predecessor. That means an older case might feel a little loose or may not sit flush against the phone.
- Curved Edges: Apple has introduced a new contoured edge design on the iPhone 15 Pro Max, making it feel smoother in hand. This means a case designed for the flat-edged iPhone 14 Pro Max won't wrap around properly, potentially making it uncomfortable or unstable.
- The Action Button: The iPhone 15 Pro Max replaces the mute switch with the new Action Button. This means that any cutout designed for the mute switch on an iPhone 14 Pro Max case won't align with the new button, limiting its functionality.
- Camera Cutout Differences: While the camera bump remains large, Apple's changes to the design could cause misalignment, affecting protection and functionality.
So, while you might be able to force an iPhone 14 Pro Max case onto an iPhone 15 Pro Max, it won't be a perfect fit—and that's a problem when you're trying to protect an expensive phone.

What about the reverse? Do iPhone 15 Pro Max cases fit 14 Pro Max? Unfortunately, the answer is still no—and here's why:

- The iPhone 15 Pro Max is thicker than the 14 Pro Max, so cases designed for it will be too tight on the older model.
- The button placement has changed, so even if a case technically fits, the buttons might not align properly.
- In our experience, the curved edges of the iPhone 15 Pro Max case don't match the flat sides of the 14 Pro Max, which can affect grip and usability.
In short: If you have an iPhone 14 Pro Max, you're better off sticking with cases specifically designed for it.
iPhone 14 Pro Max vs iPhone 15 Pro Max: Specification Differences
If you're wondering how much Apple has really changed the size of the iPhone 15 Pro Max from the iPhone 14 Pro Max, let's break down the key differences:
Size & Dimensions
Feature |
iPhone 14 Pro Max |
iPhone 15 Pro Max |
Height |
160.7 mm (6.33”) |
159.9 mm (6.29”) |
Width |
77.6 mm (3.05”) |
76.7 mm (3.02”) |
Thickness |

Material Changes
The iPhone 14 Pro Max has a stainless steel frame, whereas the iPhone 15 Pro Max introduces a titanium frame, making it lighter and more durable.
Button Differences
The mute switch has been replaced with the Action Button on the iPhone 15 Pro Max. This button is customisable, but its placement and size mean that iPhone 14 Pro Max cases won't allow easy access.

Port Differences
The Lightning port has been swapped for a USB-C port on the iPhone 15 Pro Max, which means older cases designed with precise cutouts for Lightning might not align perfectly with the new port.
Conclusion
The iPhone 14 Pro Max case might seem like it could fit the iPhone 15 Pro Max, but the differences in size, button placement, and design mean it won't provide a proper fit or full functionality. The new model is slightly smaller, has curved edges, and introduces the Action Button, making older cases incompatible.
While using an old case might seem like a quick fix, it's not worth the compromise in protection and usability. So, what cases fit iPhone 15 Pro Max? Only a case designed specifically for the iPhone 15 Pro Max will ensure the best fit, secure grip, and easy access to all features.
