Sadly, the iPhone 15 Pro Max case will not fit the new iPhone 16 Pro Max, and here’s why.
Apple has not officially announced its iPhone 16 lineup, but we’ve already learned almost everything we need to know. Tipsters and reliable Apple rumor sources have provided some information about the upcoming devices (which makes a lot of sense), including their physical dimensions. We’ve also seen leaked photos of molds for third-party cases and prototypes of the iPhone 16, iPhone 16 Plus, iPhone 16 Pro, and iPhone 16 Pro Max.
The biggest reveal we didn’t see coming was the introduction of a new size — the largest iPhone ever, and it’s no other than the iPhone 16 Pro Max. This is the main reason why you can’t use the iPhone 16 Pro Max case to its predecessor, the iPhone 15 Pro Max. Moreover, every next generation of iPhone almost always has slight design and build changes, so using an old phone case may not be compatible.
Let’s take a closer look into the iPhone 16 Pro Max’s new size, design, and other features we would want to know about its overall build.
What Is the New iPhone 16 Pro Max Size?
For the first time in years, Apple will introduce a new size in the iPhone 16 lineup. Leaked phone case molds and prototypes of the Pro Max variant suggest that the phone will be taller, at 6.9 inches. This is the largest iPhone so far, surpassing last year’s 6.7-inch iPhone 15 Pro Max.
If we compare it to the standard Pro model, which is only 6.3 inches tall, the difference is definitely significant. This will give iPhone users a wider option and diverse sizes, with the base iPhone 16 being the smallest at 6.1 inches and the iPhone 16 Plus, the second-tallest at 6.7 inches.
If the iPhone 16 Plus has the same screen size as the iPhone 15 Pro Max, does that mean you can use the same case? The answer is still no. Along with the standard iPhone 16 model, the iPhone 16 Plus will have a new camera layout and an additional button (rumored).

iPhone 15 Pro Max vs. iPhone 16 Pro Max Case
Given the significant size difference between the iPhone 15 Pro Max and the iPhone 16 Pro Max, it’s safe to say that their cases will not be interchangeable. The iPhone 16 Pro Max’s larger dimensions, along with any potential changes in camera layout or button placement, will render iPhone 15 Pro Max cases incompatible.
If you’re planning to upgrade to the iPhone 16 Pro Max, invest in a new case specifically designed for this model. This will ensure a proper fit, optimal protection, and access to all necessary ports and buttons.
Key factors to consider when choosing an iPhone 16 Pro Max case:
- Material: Choose a case made from durable materials like 600D aramid fiber to protect your device from drops, scratches, and everyday wear and tear.
- Protection level: Consider your lifestyle and the level of protection you need. Options range from slim cases for minimal bulk to rugged cases for maximum protection.
- Features: Look for additional features like wireless charging or MagSafe compatibility.
- Style: Select a case that matches your personal style and complements the design of your iPhone 16 Pro Max.
You can find the perfect case to protect and showcase your new iPhone by carefully considering these factors.
Other Things Affecting Case Compatibility
Size is not the only key factor to consider when looking for a compatible case. Apple is known to incorporate minor design and build changes every now and then to iPhones, including the following things.
Buttons
The placement and shape of buttons, such as the power and volume buttons, can vary slightly between iPhone generations. This can impact the fit of a case, especially if the case relies on precise button cutouts.
With the new leak going around about a new ‘Capture’ button in all iPhone 16 models, this makes it more impossible for the iPhone 15 Pro Max case to fit the iPhone 16 Pro Max.
Ports
The arrangement and type of ports, including the Lightning port or USB-C (if applicable), can also differ between iPhone models. Cases designed for a specific port configuration might not fit perfectly if the ports on your iPhone 16 have been altered.
Camera
The camera module is a prominent feature on iPhones, and its size, shape, and placement can change over time. Cases that are specifically designed to accommodate a particular camera setup might not be compatible with a different camera configuration on the iPhone 16.
Edges
The curvature and thickness of the iPhone’s edges can also influence case compatibility. Cases that are designed to fit a specific edge profile might not adhere properly or provide adequate protection if the iPhone 16 has a different edge shape.
Why Choose an Aramid Fiber iPhone 16 Pro Max Case
Aramid fiber cases offer a unique blend of strength, durability, and lightweight design, making them an excellent choice for protecting your iPhone 16 Pro Max. Thinborne is a leading brand renowned for crafting exceptional 600D aramid fiber cases that deliver superior strength – five times stronger and thinner than steel – without compromising style.
Scientifically speaking, Aramid fiber is a high-performance material known for its exceptional tensile strength, making it popular in the aerospace industry. Despite its incredible strength, aramid fiber is surprisingly lightweight.
Thinborne’s aramid fiber iPhone 16 series cases are designed to be as thin as possible, with Texas-based quality and compatible with MagSafe.
Wrap Up
It is expected that the Pro Max will be the most expensive phone among all iPhone 16 models, so it’s only reasonable to choose the best iPhone 16 Pro Max case. This way, you can ensure your investment is protected and can maintain its pristine look for more years.
