The iPhone 13 Pro Max and iPhone 14 Pro Max look almost interchangeable — same headline screen size, similar bodies, the same general shape. So if you have a spare 14 Pro Max protector in a drawer and a 13 Pro Max in your hand (or the other way round), it is very tempting to assume the glass will fit. Unfortunately, this is one of those swaps that looks plausible and disappoints in practice.
The short verdict: no, a 14 Pro Max protector does not properly fit a 13 Pro Max. The bodies differ by fractions of a millimetre — enough to matter at protector tolerances — and the bigger obstacle sits at the top of the screen, where the 13 Pro Max has a wide notch and the 14 Pro Max has the Dynamic Island. Here is why that combination defeats the swap.
Key Takeaways
- The phones are close but not identical: the 13 Pro Max is about 160.8 mm tall and 78.1 mm wide; the 14 Pro Max is about 160.7 mm tall and 77.6 mm wide.
- That is a width difference of roughly half a millimetre — small, but protectors are cut to tolerances tighter than that.
- The 13 Pro Max has a wide notch; the 14 Pro Max has the smaller, floating Dynamic Island — the top of the glass is shaped differently.
- A mismatched protector tends to sit off-centre, lift at the edges, or misalign around the speaker and sensors.
- Buy glass listed specifically for your model — and note that 12 Pro Max protectors are a different fit again.
Fractions of a Millimetre Still Matter
On paper, the difference sounds like nothing. The 14 Pro Max is about half a millimetre narrower than the 13 Pro Max, and their heights are within about a tenth of a millimetre of each other — treat these figures as approximate, as published dimensions can vary slightly between sources. But a screen protector is not a phone case; it has almost no tolerance to spare. It is cut to sit within the flat area of the display, stopping just short of where the glass begins to curve down at the edges.
Fit a narrower 14 Pro Max protector to a 13 Pro Max and that half-millimetre shows up as an uneven border: centre it perfectly and you still have a sliver of extra exposed glass on each side, with the protector’s edge landing closer to the curve on one axis than the design intends. Go the other way — a 13 Pro Max protector on a 14 Pro Max — and the glass is slightly too wide, so its edges ride up onto the curve of the screen. Glass that sits on a curve cannot seal properly: it lifts, collects dust underneath, and develops the familiar white “halo” border that never presses down.
The Bigger Problem: Notch vs Dynamic Island
Even if the outer dimensions matched, the top of the screen would give the swap away. The iPhone 13 Pro Max carries the wide notch that houses the speaker and the Face ID sensors in a band joined to the top edge of the phone. The iPhone 14 Pro Max replaced it with the Dynamic Island: a smaller, pill-shaped cutout that floats below the top edge, with the speaker moved to the very rim of the frame.
Protectors are shaped around these features. Many full-coverage protectors have a printed black border and precise cutouts or clear windows positioned for one layout or the other. A border printed for the notch can crowd or overlap the area around the Dynamic Island and intrude into the visible display; a protector cut for the Island generation leaves the 13 Pro Max’s notch arrangement wrongly covered or oddly exposed. Plain clear protectors without borders suffer less from this, but they still carry the width problem described above — and their speaker and sensor alignment will not be quite where the phone expects it.
- Be sceptical of any listing claiming one protector fits both the 13 Pro Max and the 14 Pro Max. Reputable makers sell them as separate products precisely because the top cutouts differ — a combined listing usually means a compromise fit for both phones.
What Happens If You Fit One Anyway?
In a genuine pinch — a cracked protector, a spare in the drawer, a replacement on the way — a plain, clear 14 Pro Max protector will physically sit on a 13 Pro Max screen and provide basic scratch cover for a day or two. Expect it to look slightly off: an uneven border, a tendency for one edge to lift, and alignment around the top that is close but never quite right. A snug case may push against the imperfect edges and make lifting worse. Treat it strictly as a stopgap, not a solution, and do not be surprised if dust creeps underneath within days.
Getting the Right Protector
The reliable fix is simply to buy glass made for your exact model. If you are unsure which phone you have, check in Settings, under General and About, where the model name is stated plainly. When shopping, look for your model named on its own rather than in a long combined compatibility list. A word of warning about the neighbouring generation, too: the 12 Pro Max is a different fit again — although its body dimensions look similar on paper, its speaker sits within the notch rather than at the top edge, so its protectors are not a correct match for the 13 Pro Max either.
- Keep the packaging from the protector you fit, or label spare protectors with the model name in a drawer. The Pro Max generations look so alike that unlabelled spares are easily mixed up — and the mistake only becomes obvious mid-installation.
Frequently Asked Questions
Will a 13 Pro Max protector fit a 14 Pro Max instead?
The same problem in reverse. The 13 Pro Max protector is about half a millimetre wider, so its edges overhang the flatter area of the 14 Pro Max screen and struggle to adhere, and its notch-era shaping does not match the Dynamic Island layout. It is no more recommended in this direction than the other.
Aren’t the two screens the same size?
Both phones are marketed with a 6.7-inch display, but that diagonal figure is where the similarity ends for protector purposes. Fit depends on the body’s width, the position of the screen’s curved edges, and the shape of the cutouts at the top — and those differ between the two generations.
Which protectors are interchangeable with the 13 Pro Max?
Realistically, only protectors made for the 13 Pro Max itself. Neither the 12 Pro Max nor the 14 Pro Max generation is a correct cross-fit, despite the family resemblance. Always match the protector listing to your exact model name rather than to the screen size or the phone’s appearance.
Half a millimetre and a differently shaped cutout are all it takes: the 14 Pro Max and 13 Pro Max may be near-twins, but their screen protectors are not interchangeable — buy for your exact model and the glass will sit flat, sealed and forgotten, exactly as it should.
