The iPhone 11 Pro Max has a 6.5-inch display, and the screen protector you need is one made specifically for that model. It sounds obvious, but the 11 Pro Max sits in a crowded family of similarly named phones — the smaller 11 Pro, the standard iPhone 11, and later Pro Max models that are all slightly different sizes — so it is easy to buy the wrong glass by mistake.
This guide explains exactly which protectors fit the iPhone 11 Pro Max, which near-miss models to avoid, and the one older phone whose protectors genuinely do interchange with it. Get the size right and installation is a five-minute job; get it wrong and no amount of careful alignment will save you.
Key Takeaways
- The iPhone 11 Pro Max needs a protector made for its 6.5-inch display and 158 × 77.8mm body.
- Protectors for the iPhone XS Max generally fit the 11 Pro Max too — the two phones are near-identical in size.
- iPhone 11 and 11 Pro protectors are too small; 12 Pro Max and later protectors are too big. Neither will fit properly.
- Choose a case-friendly cut if you use a case, so the case lip does not lift the protector’s edges.
- Check the notch cutout — a correctly cut protector leaves the Face ID sensors and speaker unobstructed.
The Exact Size: 6.5 Inches, Cut for the 11 Pro Max
Screen protectors are cut to match a phone’s physical dimensions, not just its screen size. The iPhone 11 Pro Max measures roughly 158mm tall and 77.8mm wide, with a 6.5-inch OLED display that curves gently at the edges of the glass. A correct protector covers that front panel precisely, following the rounded corners and stopping just short of where the glass begins to curve away.
When shopping, the safest approach is simply to buy a protector that names the iPhone 11 Pro Max on the packaging or listing. Reputable makers cut their glass to within a fraction of a millimetre for each model, and that precision is what gives you clean edges, working sensors and no lifting corners. Generic “6.5-inch” protectors without a model name are a gamble — several phones share that screen size but differ in body dimensions and notch layout.
The XS Max Exception: Protectors That Also Fit
There is one helpful exception to the “exact model only” rule. The iPhone XS Max, released a year before the 11 Pro Max, has the same 6.5-inch display size and a body that is within a whisker of the same dimensions. In practice, most XS Max protectors fit the 11 Pro Max well, and many products are sold as fitting both models — which is handy if you already have a spare XS Max protector in a drawer.
The reverse is also true: an 11 Pro Max protector will generally sit happily on an XS Max. The notch size and speaker placement are close enough that alignment is not usually a problem. Just be aware that this interchangeability is a happy accident of two very similar designs, not a general rule — it does not extend to any other iPhone generation.
- If a listing says “iPhone 11 Pro Max / XS Max”, that is a good sign — the two phones genuinely share a fit. If a listing lumps the 11 Pro Max in with the 12 Pro Max or 13 Pro Max, treat it with suspicion.
Models That Do Not Fit (Despite the Similar Names)
The rest of the iPhone 11 family is where mistakes happen. The iPhone 11 Pro has a smaller 5.8-inch screen, so its protectors leave a large uncovered border on the Pro Max. The standard iPhone 11 has a 6.1-inch LCD screen in a differently shaped body with a larger notch area, and its protectors do not line up either — different outline, different cutouts, wrong glass.
Later Pro Max models are equally incompatible. The 12 Pro Max moved up to a 6.7-inch display in a taller, flatter-edged body, so its protectors overhang the 11 Pro Max on every side. The 13 and 14 Pro Max kept that larger size and changed the notch again. A protector that is even a millimetre or two off will not seal at the edges, will trap dust underneath, and will usually lift within days.
Case-Friendly or Full Coverage?
Once you have the right model, you will usually choose between two cuts. A case-friendly protector is made slightly smaller than the front panel, leaving a small margin so your case’s raised lip never touches the glass edge. If you use a case — and most Pro Max owners do, given the phone’s size and weight — this is the safer choice and far less likely to lift at the corners.
A full-coverage protector extends closer to the edges, often with a black border frame that mimics the phone’s bezel for a seamless look. It protects more of the glass and suits slim cases or no case at all, but it is the cut most likely to clash with a bulky case. Decide based on the case you actually use, and if you are between the two, remember that a case-friendly protector plus a case still leaves only a sliver of screen exposed.
- Before peeling the backing off, hold the protector over the phone and check that the notch cutout, speaker slot and edges line up. Thirty seconds of dry-checking catches a wrong-model protector before the adhesive touches your screen.
Frequently Asked Questions
Will an iPhone XS Max screen protector fit the 11 Pro Max?
Yes, in most cases. The XS Max and 11 Pro Max share the same 6.5-inch display size and near-identical body dimensions, and many protectors are sold as fitting both. Check the notch alignment as you fit it, as minor cutout differences exist between brands.
Can I use an iPhone 11 or 11 Pro protector on my 11 Pro Max?
No. The iPhone 11 has a 6.1-inch screen and the 11 Pro a 5.8-inch screen, so both protectors are noticeably too small for the 6.5-inch Pro Max. They would leave a wide border of glass unprotected and the cutouts would not align with the sensors.
Does the 11 Pro Max need a special protector for Face ID?
No special technology is required — any protector correctly cut for the 11 Pro Max leaves the notch’s cameras and sensors clear, so Face ID works normally. Problems only arise with protectors made for a different model, where the cutout can cover a sensor.
For the iPhone 11 Pro Max, the rule is simple: buy for the 6.5-inch 11 Pro Max (an XS Max protector will usually do), pick the cut that suits your case, and ignore every other “Pro” or “Max” name on the shelf.
