For the iPhone 8 Plus, the best 2026 pick from Gorilla Cases is the Waterproof iPhone 8 Plus Case (Black) at $24.99. For the iPhone 7 Plus, the best picks are the Waterproof iPhone 7 Plus Case at $39.99 and the iPhone 7 Plus Aluminum Shockproof Case at $29.99.
We do not list an exact-fit case for the iPhone 6s Plus, and this comparison says so clearly.

Why This 3-Way Comparison Matters in 2026
The iPhone 8 Plus, iPhone 7 Plus, and iPhone 6s Plus are all 5.5-inch Plus phones. Many families still use them as backup phones, kids phones, or work devices.
They look alike, but they are not identical, so a case for one may not fit another. A rugged case is a smart way to extend the life of an older Plus iPhone.
This guide compares the three phones and tells you which Gorilla Cases products belong with each one. Gorilla Cases offers honest fit guidance, because the wrong case wastes money.

Size and Camera Bump
All three phones are close in size, but the iPhone 8 Plus is slightly taller, wider, and heavier. That is why a case cut for one Plus model should be treated carefully on another.
The iPhone 8 Plus and iPhone 7 Plus both have a dual-camera bump. The iPhone 6s Plus has a single lens, so camera cutouts differ.
Case Compatibility Rules
Do not assume a case fits just because the screen size matches. Camera cutouts, button positions, and glass versus aluminum backs all differ.
Always buy the case named for your exact phone. The sections below show which Gorilla Cases products fit each device.

iPhone 6s Plus: Honest Fit Guide
Gorilla Cases does not currently list a case made specifically for the iPhone 6s Plus. Our catalog has a Waterproof iPhone 6S Case, but that is for the smaller standard iPhone 6S and will not fit a Plus.
The iPhone 6s Plus shares nearly identical outer dimensions with the iPhone 7 Plus, but a different camera and button layout. We do not claim that 7 Plus cases fit, so please contact us at info@gorillacasestore.com before you try.

Which Phone Is Best to Protect in 2026?
The iPhone 8 Plus has the newest hardware, a glass back, and wireless charging. That makes it the most worthwhile of the three to protect.
The iPhone 7 Plus has the strongest range of Gorilla Cases options. The iPhone 6s Plus is the hardest to match with an exact case.
Illustrative Use Scenario
Here is an illustrative example, not a real customer review. Imagine a family that hands down an iPhone 8 Plus as a first phone for a teenager.
They pick the waterproof case for rainy bus stops and pool days. The example shows why an inexpensive rugged case is a good match for hand-me-down phones.
Protection Tips for Older Plus iPhones
- Always confirm the exact model on the back of your phone.
- Test any waterproof case in a sink before real water use.
- Check that the battery and seals on older phones are in good condition.
- Keep Lightning ports clean and dry.
- Replace cases that crack or stretch.
- Use tempered glass on the screen as well.
- Avoid heat in cars and on dashboards.
What Is in the Box and Install
Check each product page for contents. Install by powering down, seating the phone fully, and closing every seam or latch.
Confirm that buttons click and the camera opening is clear before use.
