Many people upgrading their phone eventually ask the same thing. Will an iPhone 13 Pro Max case fit an iPhone 14 Pro Max? It's a fair question, and from our experience, it comes up often because the two models look so similar at first glance.
We've spent years designing and testing cases, so we know how small changes in size, camera layout, and button placement can affect whether a case actually fits.
In this article, we walk through the direct answer, compare the key dimensions, and explain why those differences matter when you're choosing the right case.

Can an iPhone 13 Pro Max Case Fit the iPhone 14 Pro Max?
No. An iPhone 13 Pro Max case will not fit the iPhone 14 Pro Max properly. After putting it to the test and comparing both models closely, we can confirm that even small changes in width, thickness, and the camera bump prevent a secure and accurate fit.
A 13 Pro Max case might slide on, but it usually leads to misaligned buttons, a tight or uneven fit, and issues around the camera cutout.
With years in the industry, we've seen how these slight mismatches affect protection, durability, and overall usability. It's a similar situation to other phone case models, such as will an iPhone 14 case fit an iPhone 13 or will iPhone 12 case fit iPhone 14.
When deciding on a phone case, it's best to go for one that's specifically designed for your iPhone model. For an iPhone 13 Pro Max, you should use an iPhone 13 Pro Max case, and for an iPhone 14 Pro Max, you should use an iPhone 14 Pro Max case.
iPhone 13 Pro Max vs iPhone 14 Pro Max Dimensions
Understanding the physical differences between the two models helps explain why the cases are not compatible.
Height
The height differences are minimal. The iPhone 13 Pro Max measures 160.8 mm, while the iPhone 14 Pro Max sits at 160.7 mm. This is not enough to cause issues, although height alone does not determine case fit.
Width
The width is where the first real change appears. The iPhone 13 Pro Max is 78.1 mm wide, while the iPhone 14 Pro Max is slightly narrower at 77.6 mm. A case shaped for the wider 13 Pro Max often feels loose on the 14 Pro Max and does not grip the edges the way it should.
Depth
Thickness affects case fit dramatically. The iPhone 13 Pro Max is 7.65 mm thick, and the iPhone 14 Pro Max is 7.85 mm thick. That extra thickness means a 13 Pro Max case usually feels too tight on the 14 Pro Max. Some cases will not snap on at all, while others create unwanted pressure points on the phone.
Camera and Buttons
The camera module on the 14 Pro Max is larger than the module on the 13 Pro Max. This alone prevents the camera opening on a 13 Pro Max case from lining up correctly. There are also small shifts in button placement. When these do not match the cutouts on the case, the buttons feel stiff or unusable, and the case does not sit comfortably in the hand.

Conclusion
It's clear that the iPhone 13 Pro Max and iPhone 14 Pro Max differ in ways that affect how a case fits, even if the phones look close in size. The small changes in width, depth, camera design, and button placement make older cases unsuitable for the newer model, which means a proper fit depends on choosing one built specifically for the 14 Pro Max.
Understanding these differences makes upgrading smoother and helps you avoid cases that feel tight, loose, or misaligned. If you're ready for a case that fits perfectly and looks great, check out our iPhone 14 Pro Max collection at The Dairy.
