The best case to protect your iPhone’s camera bump has a raised rim that sits above the tallest lens ring on every side, so the lenses never touch a desk, bench or car seat when the phone is face up. On the iPhone 17 Pro and 17 Pro Max, this matters more than on earlier models, because the full-width camera plateau stands well clear of the back panel.
A flat-backed case protects the back glass but still leaves the lenses as the highest point on the phone. This guide explains how much clearance to look for, how a raised rim compares with a sliding camera cover, and what to check before you buy for your Pro Max.
Apple lists the iPhone 17 Pro Max body depth at 8.75 mm, but that figure excludes the camera. Measurements shared by Max Tech put the 17 Pro Max at roughly 11.2 mm across the camera plateau and about 12.9 mm at the top of the lenses, so the lenses stand around 4 mm proud of the back glass. The iPhone 18 Pro Max continues the large plateau design, and early dummy-unit measurements pointed to a slightly taller plateau and lenses again. Always check the case maker’s stated rim height for your exact model.
The most important thing is simple: the case must sit above the camera lenses but not block the lenses, flash or other sensors.
Highlights
- A raised camera rim helps keep large camera bumps away from hard surfaces.
- If the case is flat, the camera lenses can end up being the highest point on the phone.
- A useful design rule of thumb is to provide approximately 1 mm to 1.5 mm of clearance above the highest lens ring, assuming measurements use the same datum.
- Sapphire crystal is scratch-resistant, but it can chip when struck.
- Scratches on a camera cover can cause glare and reduce contrast, as DXOMARK testing has shown.
- Sliding camera covers protect the lenses when closed, but their moving parts can trap dust.
Why iPhone Camera Bumps Keep Getting Bigger
The iPhones used to have smaller camera modules. The iPhone 11 Pro was the first to use a square camera island with three lenses. Later models made the camera area even bigger.
The iPhone 13 Pro camera cutout was about 38 mm x 37 mm. The iPhone 17 Pro camera plateau has been pushed out to a larger area at the top of the phone, and the iPhone 18 Pro Max, released in September 2026, uses a similar design.
Larger camera islands create two separate issues. The case needs a bigger cutout first of all, which means more of the back panel will be exposed. The lenses may also stand proud of the surrounding frame, increasing the likelihood of contact with surfaces.
That’s why protecting the camera cutout is just as important as bumpers on the corners and protecting the back panel.
Why Flat Back Cases Leave Your Camera Lenses Exposed
A phone case is there to absorb and disperse the energy of an impact. Flexible materials such as TPU will flex a little bit, reducing the amount of force transferred to the phone.
But a case with a flat back and only a low camera edge may not sufficiently protect the lenses.
Here is why a flat back falls short. On the iPhone 17 Pro Max, the lenses stand roughly 4 mm above the back glass (about 12.9 mm total depth against 8.75 mm for the body). A slim case back is typically only 1 mm to 2 mm thick, so the lenses can still sit 2 mm to 3 mm higher than the case. When you put the phone down, the lenses can touch the surface before the case does.
A raised rim solves this by lifting the lenses off the surface. A rim that sits 1 mm to 1.5 mm above the tallest lens ring keeps the lenses clear when the phone is placed face up.
This protection is also very important in everyday situations. Dragging your phone over a desk can cause the camera covers to swipe up against dust and grit. A raised rim helps to minimise contact, but not all impact or damage can be prevented.
Raised Camera Rings vs. Sliding Camera Covers
There are two common approaches to camera protection: a raised perimeter ring and a sliding camera cover.
Both help protect the camera area, but they work differently.
| Feature | Raised Perimeter Ring | Sliding Camera Cover |
|---|---|---|
| How it protects | Keeps the camera lenses above the contact surface | Covers the camera opening when closed |
| Typical clearance | Around 1.0 mm to 1.5 mm above the tallest lens ring | Covers the lenses when closed |
| Protection from flat-surface contact | Yes, when the rim is high enough | Yes, when the cover is closed |
| Protection from pocket scratches | Helps keep surfaces away from the lenses | Covers the lenses when closed |
| Moving parts | None | A sliding mechanism and track |
| Effect on photo quality | No direct effect when properly designed | Poorly positioned parts can cause glare or block part of the image |
| Effect on wireless charging | No direct effect | No direct effect |
| Added thickness | Approximately 1 mm to 2 mm over the camera plateau | Approximately 1.5 mm to 3 mm |
A simple solution for everyday use is a raised camera rim. It works without having to shut a cover every time you put your phone away.
If you work in dusty environments or spend a lot of time outdoors, a sliding cover is worth considering. It provides a physical barrier when the camera is not in use, though its track can accumulate dust and lint.
Make sure the cover is fully off the lenses when taking pictures.
Sapphire and the Camera Cutout: What It Can and Cannot Do
Apple lists a sapphire crystal lens cover on the iPhone 17 Pro. Sapphire resists scratches from everyday objects, but it isn’t impact-proof. A direct hit on an exposed edge can still chip or crack it.
That’s why the case around the camera matters as much as the lens material. A raised rim keeps hard surfaces and grit away from the lens cover, which protects both the glass and the image quality behind it.
The solid camera cutout protects lenses against hard surfaces and reduces direct contact with grit. It also avoids damage that could affect the quality of the image.
According to the DXOMARK article, scratches on a smartphone camera cover can affect contrast and cause glare or stray light, especially when the light source is behind the subject. Texture, noise and autofocus were not equally affected.
To summarise, a scratched camera cover may not prevent the camera from working, but it can affect the photos and videos you take.
Repairs can also be inconvenient. Depending on the damage, a Pro model may need the whole rear camera assembly replaced, so prevention is easier than a fix. Apple’s support site lists the current repair options for your model.
A good-fitting case with a raised rim can help reduce the day-to-day wear and tear that your camera lenses are exposed to.
How to Choose a Lens Case for Your Pro Max iPhone
Not all iPhone Pro Max lens cases are created equal in protection. A raised edge is only useful if it is high enough to keep the lenses from the surrounding surfaces.
Here are four things to consider before you buy them.
Check the Height of the Camera Rim
Note the space between the top lens ring and the upper edge of the case of rim. Knowing the height of the rim alone won’t tell you if the lenses actually will have enough clearance.
If a rim just clears the lenses, it may offer little protection if the case flexes under pressure. Look for exact dimensions and a design that keeps the lenses off of flat surfaces.
Check All Around the Camera
The raised rim is supposed to wrap all the way around the camera section. There are cases with higher outer edges but still leave parts of the inner edge close to the lenses.
Check out the product photos from different angles to see if the camera island is protected on all sides.
Check the Shape of the Rim
The rim is straight and vertical, making a distinct barrier from the lenses, but the edge can catch on pockets or fabric. A slightly angled or chamfered rim feels smoother and is less likely to catch on things.
Choose a design that provides enough room but is still comfortable to hold and use.
Check Which iPhone Model You Have
Cases made for older iPhone models may not fit correctly with the camera layout of newer models. Minor differences in lens placement and the size of the camera island can result in gaps, or the protective rim extending too close to a lens.
Choose a case that is designed for your model. Be sure to allow the lenses, flash and other sensors to remain unobstructed in the opening.
The protective iPhone cases range lists the camera lip height by model so you can compare the options available.

Final Thoughts: Choose a Case That Protects Your Camera
Today’s iPhones have bigger camera islands and more pronounced lenses, so protecting the camera is a big consideration when choosing a case.
A flat-backed case can safeguard the back panel, yet it leaves the lenses unprotected. The elevated rim ensures the camera remains above desks, tables, and other hard surfaces.
When you purchase an iPhone Pro Max lens case, always check the height of the rim, the whole camera perimeter, the shape of the edges, and that it fits your exact model. The camera cutout protection should be enough to allow enough clearance without obstructing any lens or sensor.
Sleek Cases emphasises practical protection and a clean design. Our protective iPhone cases are custom-made for their models, protecting the most vulnerable areas of the phone.
Before you buy a case, measure how far the tallest camera lens sticks out and make sure the protective rim sits above it.
