iPhone 16 vs iPhone 15: Design changes
To determine if your iPhone 15 case will fit the iPhone 15, we need to understand the design differences between the two models. Below are the key design differences between the iPhone 16 and iPhone 15 and the iPhone 15 Plus and iPhone 16 Plus.
- Dimensions: Every year, Apple makes some subtle changes to the design of its iPhone models, and the same is true for the iPhone 16 lineup. While the iPhone 16 and iPhone 15 models share similar width and depth (2.82 inches and 0.31 inches, respectively), Apple has made some changes to the height. The iPhone 16 is 0.03 inches (1.1 mm) taller than the iPhone 15.

| Size | 6.1 inches | 6.1 inches | 6.7 inches | 6.7 inches |
| Dimensions | Height: 5.81″Width: 2.81″Depth: 0.32″ | Height: 5.81″Width: 2.82″Depth: 0.31″ | Height: 6.34″Width: 3.05″Depth: 0.32″ | Height: 6.33″Width: 3.06″Depth: 0.31″ |

Design changes between iPhone 16 and iPhone 15
- Different camera modules: One of the biggest design differences between the iPhone 16 and iPhone 15 is the rear camera module. The iPhone 15 and 15 Plus feature a square camera island with diagonally placed lenses. In contrast, the iPhone 16 and 16 Plus feature a pill-shaped camera island with vertically stacked lenses. If you try to put an iPhone 15 case on an iPhone 16, it won’t line up perfectly with the rear camera.
- New buttons: Compared to the iPhone 15 and 15 Plus, the iPhone 16 and 16 Plus also get two new buttons. One of them is the Action button that replaces the Mute button on the iPhone 15 and 15 Plus. The Mute button and the Action button might have the same location, but their usage differs. Then, there is an all-new Capture button that brings several camera-related features like zooming in/out, adjusting focus, and more.
Will the iPhone 15 case fit the iPhone 16?
Speaking of whether the iPhone 15 case will fit the iPhone 16, the answer is “no”Although the new iPhone 16 is the same size as the iPhone 15, its dimensions differ slightly.
Additionally, the iPhone 16 has a vertically aligned camera setup on the back, rather than the diagonal camera setup of the iPhone 15. Due to a new camera design on the iPhone 16, the old iPhone 15 case might not match and fit properly. It might obstruct the camera or not protect it properly. Honestly, it will also look weird and ugly. 
There is also an action button and a capture button on the iPhone 16 and 16 Plus. Your iPhone 15 case there will be no cutout for the Capture button. So you will miss all the new features that the dedicated camera button brings.
Even if you can snap on an iPhone 15 case and the mute button cutout lines up with the iPhone 16’s Action button, it won’t provide the same experience as a case that’s specifically designed to accommodate the Action and Capture buttons. And you wouldn’t want to compromise on the new camera module, Action button, and Capture button just to use an old case. Right?
So, long story short, the iPhone 15 case might work with the iPhone 16, but it won’t fit perfectly to provide a secure feel.
Will the iPhone 15 Plus case fit an iPhone 16 Plus?
No, your iPhone 15 Plus case not suitable for iPhone 16 Plusand you already know all the reasons why. Besides slight changes in dimensions, there is a vertically aligned camera system, an action button and a new capture button that make the iPhone 16 Plus quite different from the iPhone 15 Plus. So, an iPhone 15 case will not fit perfectly on an iPhone 16 Plus. Even if you manage to pick one up, don’t expect a promising fit.
