Are you wondering if your old phone case will do the trick for your brand-new iPhone? With a wide range of iPhone models available, it can be confusing to determine which cases may be compatible with your specific device. In this guide, we'll break down the compatibility of iPhone cases, helping you figure out whether your old phone case will fit your new iPhone.

iPhone Models with Similar Dimensions:

Here's a quick overview of the iPhone models that we'll be covering today, along with their screen sizes:

  • iPhone 6 and 6s: 4.7 inches
  • iPhone 6 Plus and 6s Plus: 5.5 inches
  • iPhone 7 and 8: 4.7 inches
  • iPhone 7 Plus and 8 Plus: 5.5 inches
  • iPhone X and XS: 5.8 inches
  • iPhone XR and 11: 6.1 inches
  • iPhone 11 Pro Max and XS: 6.5 inches
  • iPhone 12 and 12 Pro: 6.1 inches
  • iPhone 13 and 14: 6.1 inches

We'll now go into more detail on each of these pairings, and how compatible phone cases are between them.

Does an iPhone 6 case fit an iPhone 6s?

Cases designed for the iPhone 6 are often compatible with the iPhone 6s, and vice versa. Their physical designs are indistinguishable, with only extremely small millimeter differences. The key features such as the camera, volume buttons, and power buttons are positioned identically on both devices.

Does an iPhone 6 Plus case fit an iPhone 6s Plus?

The iPhone 6 Plus and iPhone 6s Plus have very similar dimensions, so cases designed for one model are generally compatible with the other. Their cameras, buttons, and ports are placed in the same locations. 

Does an iPhone 7 case fit an iPhone 8?

iPhone 7 cases are generally compatible with the iPhone 8, and vice versa. Both the iPhone 7 and iPhone 8 feature a 4.7-inch display and share nearly identical dimensions, including button placements, camera locations, and port positions.

Does an iPhone 7 Plus case fit an iPhone 8 Plus?

Cases designed for the iPhone 7 Plus are mostly compatible with the iPhone 8 Plus, and vice versa. The iPhone 7 Plus and iPhone 8 Plus only have very small millimeter differences in their dimensions, so most cases will be interchangeable.

Does an iPhone X case fit an iPhone XS?

Cases designed for the iPhone X are typically compatible with the iPhone XS, but the camera placements are slightly different for these two iPhones. The camera of the iPhone XS is slightly bigger than the camera of the iPhone X, so keep this in mind when trying to mix and match cases. Some cases may fit well, while others won't.

Does an iPhone XR case fit an iPhone 11?

The iPhone 11 and iPhone XR are the same size, but the camera areas are vastly different. The iPhone XR features a dual-camera system arranged vertically on the back, while the iPhone 11 boasts a dual-camera system positioned within a square camera bump. Therefore, cases specifically designed for the iPhone XR will not fit the iPhone 11, but cases for the iPhone 11 can fit the iPhone XR (though the camera area will be larger than necessary).

Does an iPhone 11 Pro Max case fit an iPhone XS Max?

The iPhone 11 Pro Max and iPhone XS Max do have the same dimensions, but their camera bumps are different. The iPhone 11 Pro Max features a larger square camera module with multiple lenses, resulting in a bigger camera bump compared to the iPhone XS Max. Cases made for the iPhone XS Max won't fit an iPhone 11 Pro Max, but it may be possible to use an iPhone 11 Pro Max case on the iPhone XS Max.

Does an iPhone 12 case fit an iPhone 12 Pro?

Yes, cases designed for the iPhone 12 are generally compatible with the iPhone 12 Pro, and vice versa. The iPhone 12 and 12 Pro are the same size, and they share identical dimensions, including the same 6.1-inch display screen, button placements, and overall physical design.

Will an iPhone 13 case fit an iPhone 14?

It's possible for your iPhone 13 case to fit your iPhone 14, and vice-versa. It's important to note, however, that the depth of the iPhone 14 is .01 inches larger than the iPhone 13, and the iPhone 14's camera bump is also slightly bigger. The buttons on the iPhone 14 are also slightly shifted, so there may be incompatibility for the buttons. Certain phone cases may be interchangeable, but it's not guaranteed.


Cameras, Port Openings, and Buttons (Oh, my!)

One crucial aspect of iPhone case compatibility is the alignment of the camera, port openings, and buttons. Make sure the case you choose doesn't obstruct your iPhone's cameras, flash, charging ports, or buttons. Even if two iPhones have virtually the same dimensions, differences in these areas may cause phone cases not to be interchangeable, which is why it is recommended to purchase a new phone case specifically tailored to your iPhone.

So, in conclusion, there are phone models that do have phone case compatibility. A lot of the time, it comes down to the specific phone case that you want to match to your other iPhone. For maximum compatibility and protection, we recommend investing in a new phone case for your new iPhone.
