Apple's latest lineup has caused a fair bit of confusion, and one of the most common questions we hear is: Will an iPhone 15 Pro Max case fit the iPhone 15 Plus?
It's a great question, especially since both models share the same screen size and look quite similar at first glance. But after years in the phone case industry and plenty of hands-on testing, we know the smallest design changes can make a big difference.
In this guide, we'll explain exactly why these two models aren't interchangeable, highlight why choosing the right case matters, and share some of our favourite iPhone 15 Plus cases that blend protection with personality.
The short and clear answer is no, a case for the iPhone 15 Pro Max will not fit the iPhone 15 Plus correctly. Even though both phones share a 6.7-inch display, their dimensions and button placements are different. The iPhone 15 Plus is slightly taller and has a different camera bump layout compared to the Pro Max. The difference might seem small, but it's enough to make the case incompatible.
If you try to use a Pro Max case on the Plus model, the fit will be off. The buttons won't line up, the camera cut-out won't match, and the phone might feel loose or uneven inside the case. From our experience, even a millimetre of difference can lead to poor protection and an awkward grip. That's why it's essential to use a case specifically designed for your iPhone model.

Choosing a case made for the iPhone 15 Plus ensures everything fits as it should. From our experience, that means all ports, buttons, speakers, and the camera module are perfectly aligned. A case designed for the right model gives you the best protection while keeping your phone's features fully accessible.
A mismatched case can shift around, feel bulky, or leave parts of your phone exposed. With years in the industry, we've seen this cause scratches, broken corners, or even damaged lenses. The right fit also enhances usability, making your phone comfortable to hold and stylish to show off.
