The short answer: the iPhone 16 Plus needs a case with Action button and Camera Control cutouts, the iPhone 15 Plus needs USB-C port clearance without those buttons, and the iPhone 14 Plus needs a Lightning-era cutout plus the widest metal case selection. The iPhone 16 Plus Metal Rugged Case is the most protective build across this group at MIL-STD-810G with a bonded screen guard.
Gorilla Cases offers Plus-size builds across all three generations. This comparison covers what changed and why a Plus case does not carry forward.
Why This Comparison Matters in 2026
The Plus line is Apple's large non-Pro option, and all three of these phones are close enough in size to look interchangeable. They are not.
Apple added two hardware buttons across this stretch. The Action button arrived on the 15 Pro line and reached the 16 series broadly, and Camera Control arrived with the 16 series.
Apple also switched from Lightning to USB-C between the 14 Plus and the 15 Plus. That changes the bottom cutout dimensions.
Any one of those changes makes a case from the wrong generation either unusable or missing a button.
Head to Head: Physical Specifications
- iPhone 16 Plus: 160.9 x 77.8 x 7.80 mm, 199 g, 6.7-inch display, Action button plus Camera Control, USB-C
- iPhone 15 Plus: 160.9 x 77.8 x 7.80 mm, 201 g, 6.7-inch display, standard mute switch, USB-C
- iPhone 14 Plus: 160.8 x 78.1 x 7.80 mm, 203 g, 6.7-inch display, standard mute switch, Lightning
The 16 Plus and 15 Plus share exact external dimensions. What separates them is entirely the button layout on the side rails.
Button and Port Compatibility
This is the deciding factor in this comparison. A 15 Plus case on a 16 Plus covers the Camera Control entirely, which disables one of the phone's headline features.
A 16 Plus case on a 15 Plus leaves an open hole where the Camera Control would be. That is cosmetic rather than functional, but it also means dust entry.
A 14 Plus case has a Lightning-sized bottom cutout, which is narrower than USB-C needs on many cables.
Winner: none. Buy for your exact generation.
Rugged Protection Options
The iPhone 16 Plus has the strongest rugged option in this group. The metal rugged case pairs an aluminum frame with a built-in screen protector.
The iPhone 15 Plus Rugged Aluminum Case is the equivalent for that generation. It uses the same architecture without the Camera Control cutout.
The iPhone 14 Plus Metal Case covers the oldest generation with a dustproof, shockproof armored build.
Winner: iPhone 16 Plus, by a narrow margin, on the strength of the bonded screen guard.
Water Protection Options
Sealed IP68 cases are available for the 16 Plus and the 15 Plus. The iPhone 16 Plus Waterproof Case and the iPhone 15 Plus Waterproof Case both seal to 2 meters for 30 minutes.
All three phones shipped IP68 rated from the factory. The case matters because those adhesive seals degrade with age and liquid damage is excluded from warranty.
Winner: tie between the 16 Plus and 15 Plus, since both have sealed options.
Slim Options
The iPhone 15 Plus Slim Case is the thinnest build in this comparison. Slim cases trade drop rating for pocketability.
If you want a Plus-size phone to stay pocketable, that is the tradeoff to make consciously. A slim case will not survive a 4-foot drop the way a rugged one does.
Winner: iPhone 15 Plus for slim selection.
Who Should Buy Which
iPhone 16 Plus owners should buy the metal rugged case if protection is the priority, or the sealed waterproof case if water is the hazard. Either way, verify the Camera Control cutout.
iPhone 15 Plus owners get the widest selection in this group, from slim to rugged aluminum to sealed IP68.
iPhone 14 Plus owners should buy the metal case with screen protector. It is the most complete option for a Lightning-era Plus.

An Illustrative Use Scenario
Here is an example of why generation matters here. This is an illustrative scenario, not a customer testimonial.
Picture someone upgrading from a 15 Plus to a 16 Plus and keeping the old case, since the dimensions match exactly. It fits perfectly.
Then they try to use Camera Control and find it covered by solid case material. The phone's marquee new feature is simply gone.
Nothing is damaged, but a feature they paid for is disabled by a case that fits. That is the entire argument for buying per generation.

Final Verdict
The 16 Plus wins on rugged protection, the 15 Plus wins on selection breadth, and the 14 Plus wins on being the cheapest of the three to keep running. All three are 6.7-inch phones that deserve a proper case.
The only mistake to avoid is assuming matching dimensions mean matching cases. On the Plus line, the buttons are what differ.
