Why This Comparison Matters in 2026
The iPhone 15 Pro Max, iPhone 15 Pro, and iPhone 15 Plus all launched in 2023, and all three are in heavy use in 2026. They share a USB-C port, but their bodies, cameras, and sizes differ. A case that fits one will not fit another.
That is the most common mistake we see. Two of these phones share a 6.7-inch screen size, yet their camera layouts and dimensions are different, so a sealed case cannot be swapped between them. Every Gorilla Cases listing states plainly which model it fits.
This guide compares the phones, then pairs each with the right case. Whether you want the best iPhone 15 Pro Max case, the best iPhone 15 Pro case, or the best iPhone 15 Plus case, the answer starts with an exact fit.
Side-by-Side: The Three Phones
| Feature | iPhone 15 Pro Max | iPhone 15 Pro | iPhone 15 Plus |
|---|---|---|---|
| Display size | 6.7-inch | 6.1-inch | 6.7-inch |
| Body | Titanium | Titanium | Aluminum |
| Dimensions | 159.9 x 76.7 x 8.25 mm | 146.6 x 70.6 x 8.25 mm | 160.9 x 77.8 x 7.8 mm |
| Weight | 221 g | 187 g | 201 g |
| Charging port | USB-C | USB-C | USB-C |

Those dimensions are Apple's published figures for the three phones, and they explain why each needs its own case. The Pro Max and the Plus are similar in height but differ in thickness and camera plateau.

Picture This Example Scenario
Picture this example: a family of three shares a beach rental, and each person carries a different iPhone 15. One has the Pro Max, one the Pro, and one the Plus. Because each phone has its own sealed case, nobody has to borrow a mismatched shell.
This is an illustrative example, not a customer review. The takeaway is practical: the family buys three cases sized to three phones, instead of hoping one design stretches across all of them.
Protection Tips for All Three Phones
- Order the case that names your exact iPhone 15 model.
- Clean the phone before sealing so no sand sits under a gasket.
- Run a 30-minute paper-towel test before the first swim.
- Rinse the closed case in fresh water after salt or chlorine.
- Avoid alcohol wipes on gaskets and clear panels.
- Use the volume buttons as the shutter underwater.
- Do not stack a second screen protector under a built-in one.
- Re-test the seal after a hard drop.
What Is in the Box and Installation
Each waterproof case ships as a two-piece enclosure that snaps together by hand. The Pro Max version includes the front sheet with the built-in protector and a clear back sheet. The Pro Max metal version adds a free wrist lanyard.
To install any of them, clean your phone, lay it face-down into the front half, and snap the back half on from the top around the perimeter. Check the seam for gaps. Then test the buttons and ports before you go near water.
