However, when it comes to compatibility, you'd want to take another look, especially if you have a couple of iPhone models and want to buy a case that will fit multiple phones. In addition, if you have a tremendous iPhone case collection, we'll help you explore which cases are suitable for more models. So, without further ado, let's talk about iPhone case compatibility.

Quick Links


  • If you have an iPhone 6 or an iPhone 6S, you're in luck – the cases for these two models are usually compatible. That's because they share the same physical dimensions and design. You can often use a case made for one on the other without a problem. 
  • An iPhone 7 case should fit an iPhone 8 without any issues. Cases and accessories originally designed for the iPhone 7 should be compatible with the iPhone 8 as well.
  • iPhone 13 will fit iPhone 14 case. However, your case won't work the other way around because of the 0.01-inch depth difference.
  • iPhone 12 and iPhone 12 Pro dimensions are compatible with each other. You can use their cases simultaneously.
  • iPhone SE (second generation), iPhone 7, and iPhone 8. These models have identical dimensions meaning interchanging cases is possible. In plain words, if you are using an iPhone SE model (second generation) and plan on buying an iPhone 7 or 8, you can use the same case.

iPhone Case Compatibility Guide

  • Cases designed for the iPhone 6 Plus and 6S Plus are generally interchangeable since these two models have nearly identical dimensions. Similarly, cases made for the iPhone 7 Plus should also fit the iPhone 8 Plus without any issues, as these models share similar dimensions. However, some case manufacturers may make slight adjustments to ensure the best fit, so it's always a good idea to double-check with the manufacturer or retailer to ensure compatibility. So, in most cases, you can use a case made for the 6 Plus on a 6S Plus, and a case for the 7 Plus on an 8 Plus, but it's wise to confirm with the manufacturer to be certain.
  • iPhone 11 Pro and iPhone XS look almost identical and have approximately the same size. The only difference is the placement of the camera. Certain case models can be used for both phone models, but remember that specifically tailored iPhone cases for iPhone 11 Pro won't fit iPhone XS because of the difference in camera placement.

  • iPhone 11 Pro Max and iPhone XS Max mirror their smaller counterparts, meaning they have almost identical dimensions. To put things simply, you can use the same phone case for both models.
  • The iPhone SE 2 (2020) and iPhone SE 3 (2022) share identical dimensions, making them perfect candidates for interchangeable cases. If you own either of these SE models, you can comfortably use the same case for both, ensuring your device remains protected.

Restrictions and exceptions

Even though there is a wide range of similar and identical-sized iPhone models with a suitable design, there are many restrictions regarding using your iPhone case on multiple phones. To avoid buying an iPhone case that won't fit all your iPhone models, check out our list of restrictions and exceptions below.

  • iPhone X and iPhone XS. Although these models have almost identical dimensions, there is a significant difference in design. The speaker grille and the camera placement do not match, implying that cases specifically designed for iPhone XS may not fit iPhone X.
  • iPhone SE (1st generation). Even though the 1st generation iPhone SE has the same dimensions as the iPhone 5 and iPhone 5s, there is a significant difference in camera placement. Cases explicitly designed for the iPhone SE will not fit the iPhone 5 and iPhone 5s. The same goes the other way around, meaning that cases explicitly designed for iPhone 5 and iPhone 5s won't fit iPhone SE (1st generation).
  • iPhone 11 and iPhone XR. iPhone 11 phone case will fit iPhone XR. However, you can't apply the same rule the other way around.
  • iPhone 11 Pro Max and iPhone XS Max mirror their smaller counterparts, meaning they have almost identical dimensions. Even though you can use your iPhone 11 Pro Max case for iPhone XS Max, we can't say the same contrariwise.
  • You can't use a case made for the iPhone 12 mini on an iPhone 13 mini, or the other way around. This is because the camera bump on the back of the two phones looks different. So, to keep your phone safe and all the buttons accessible, you should use a case that's meant for your exact iPhone model.

What about iPhone 15 cases?

If you're wondering whether an iPhone 14 case will fit the new iPhone 15, unfortunately, the answer is no. The cases made for iPhone 14 won't fit the new iPhone 15 because the iPhone 15 is a bit different in size. Also, the iPhone 15 series features a dynamic island instead of a notch, which influences case compatibility.

Another change is that the new iPhone 15 uses a USB-C port instead of the old lightning port. This means the charging and accessory ports are different, so old cases won't work. Due to all these factors, when you get a new iPhone 15, you'll definitely need a new case. When doing so, choose eco-friendly iPhone 15 cases and consider responsible disposal of old cases to protect the environment.

How to choose the right iPhone case

Choosing the right iPhone case is a pretty easy task as long as you know exactly what you want. However, some people tend to buy before thinking, to find out later that their iPhone case doesn't match all of their iPhone models. In addition, most iPhone cases available are made of plastic and tend to get worn out very soon. One of the biggest problems here is discoloration, especially when talking about lighter-colored cases, as they absorb dirt that cannot be cleaned easily. Furthermore, iPhone cases are often overpriced without any legit background. Most of the print is done sloppy, and you'll likely have to buy a new one every few months.

So, when shopping for a new iPhone case, we recommend carefully considering the actual materials used in the production process.

Some plastic cases, and there is no way to know exactly which ones, are made under very shady terms since overproduction, especially when talking about highly cheap materials, can't be controlled easily.

However, this doesn't mean there aren't high-quality iPhone cases made using sustainable practices such as upcycled materials, byproducts, and single-fraction manufacturing methods. These sustainable practices and methods ensure minimal waste is produced during the process.

A very common misconception that iPhone cases made of sustainable materials are not durable is completely unfounded. Of course, our best advice is to try some of them out, as companies that truly care about nature and customer satisfaction have very creative designers creating unique prints.

Remember that today's market is flooded with "fake" sustainable companies using greenwashing techniques, so make sure to buy your iPhone case from a legit producer.
