Can an iPhone 13 Pro Max Case Fit the iPhone 15 Pro Max Model?

Every phone owner understands the importance of having a protective case and glass screen to protect their device. With technology constantly evolving, knowing if your case will be compatible with future models is crucial. But sometimes, new features and design changes in each new phone model can significantly affect case compatibility, from differences in dimensions and camera placement to adding new ports or buttons. Many factors can make a case incompatible with a newer phone. Let’s take a closer look at the potential changes that could impact the compatibility of your iPhone 13 Pro Max case with the new iPhone 15 Pro Max.

Does iPhone 13 Pro Max case fit iPhone 15 Pro Max?

Apple has made a significant change in the design of its latest iPhone series, moving away from the soft and curved edges found on previous models such as the iPhone X, XS, XR, 11, and 11 Pro. Instead, they have embraced a flat edge design reminiscent of earlier models like the iPhone 4, 4S, 5, 5S, and the original SE. This shift towards a more classic aesthetic brings a sense of familiarity to long-time Apple users. However, it also means that many old cases specifically designed for the previous models will no longer be compatible with the iPhone 12, and 13 series.

iPhone 13 Pro Max Case vs iPhone 15 Pro Max Size

There are a few notable differences when comparing the iPhone 13 Pro Max sizes and the iPhone 15 Pro Max. The iPhone 13 Pro Max measures 160.8 x 78.1 x 7.65 mm, while the 15 Pro Max comes in at 159.9 by 76.7 by 8.25 mm. This means the new iPhone 15 Pro Max is slightly smaller in width, height, and length than the iPhone 13 Pro Max. However, it is worth mentioning that the new model is thicker, measuring 0.32 inches, compared to the 0.30 thickness of the old iPhone.

The difference in thickness between the two models seems small, but it could impact the compatibility of cases. The 13 Pro Max cases will not fit perfectly on the iPhone 15 Pro Max due to the slightly thicker build. Additionally, another factor that could affect the compatibility of cases between the two models is the placement of buttons. The location and design of buttons on the iPhone 15 Pro Max might differ from those on the 13 Pro Max. This further adds to the potential incompatibility issue when using the previous case on a new model.

Does iPhone 15 Pro Max need a case?

Since our old iPhone cases won’t work with the new ones, let’s dive into why you should use a case for your new iPhone 15 Pro Max. Here are some reasons:

  • Protection
  • Enhanced grip
  • Durability
  • Style
  • Customization
  • Compatibility

How do you choose a suitable case for protection?

Here are some factors to consider when choosing the right case for protection:

Determine Your Protection Needs

The first step to choosing the right case for your iPhone is to determine how much protection you need. If you drop your phone frequently or lead an active lifestyle. You may opt for a shockproof case that offers maximum protection. On the other hand, if you prefer an ultra-slim look and do not engage in high-risk activities. A lightweight and minimalistic case may suffice.

Consider Compatibility with Next-Gen iPhones

As mentioned, Apple releases new versions of iPhones yearly, with slight design changes and dimensions. This can affect the compatibility of cases designed specifically for older models. When purchasing a case, check if it is compatible with the future iPhone 15 Pro Max model. This way, you won’t have to buy a new one each time you upgrade your device.

Material Matters

The best case material plays a vital role in protecting your iPhone 15 Pro Max. Some popular case materials include TPU, rubber, plastic, Alcantara, leather, and metal. Each has its unique features and levels of protection. For example, silicone and rubber cases offer shock absorption, while metal cases provide higher durability.

Look for Drop-Tested Cases

A 6 ft drop is not similar to a 9 ft drop test. These 15 Pro Max cases have been tested to measure their ability to withstand drops from different heights onto various surfaces. This can give you an idea of how well the case will protect your iPhone in real-life scenarios.

Consider Additional Features

Aside from protection, some offer additional features such as card holders, lanyards, kickstands, or waterproof capabilities. Depending on your needs, these can be helpful in certain situations and may be worth considering.

Check Reviews and Ratings

Lastly, checking reviews from other users before purchasing is always a good idea. This can give you insight into the quality and effectiveness of the product in real-world situations.


The slight differences in size and button placement between the iPhone 13 Pro Max and the iPhone 15 Pro Max make it essential to select a case specifically designed for the new model. Therefore, choosing the right case for your new phone requires considering your protection needs, compatibility with future models, material, drop-test results, additional features, and reviews from other users.
