They’re both iPhones from roughly the same era, they both have a notch, and protectors for the two are often sold side by side — so it’s a fair question: will an iPhone 11 screen protector fit an iPhone X? The short answer is no. Despite the family resemblance, the iPhone 11 is a physically bigger phone than the iPhone X, and its protectors are cut for that bigger body.
This is one of the most common fit mix-ups in the iPhone range, because the names give nothing away. Below are the actual dimensions that settle it, what goes wrong if you try the swap anyway, and the pairings that do work — because both phones have a true twin elsewhere in the line-up.
Key Takeaways
- The iPhone 11 has a 6.1-inch display in a body around 150.9 × 75.7 mm; the iPhone X has a 5.8-inch display in a body around 143.6 × 70.9 mm.
- An iPhone 11 protector is roughly 7 mm taller and 5 mm wider than the X’s screen area — it will overhang on every side.
- The iPhone X’s true pairing is the iPhone XS: same body, same protector.
- The iPhone 11’s true pairing is the iPhone XR: same body, same protector.
- Tempered glass cannot be trimmed to make a wrong-size protector fit — it will shatter if you try to cut it.
The Dimensions That Settle It
Screen protectors are cut to the phone’s body, not its marketing name, and on body size these two phones are clearly different. The iPhone 11 measures about 150.9 mm tall and 75.7 mm wide, housing a 6.1-inch LCD display. The iPhone X measures about 143.6 mm tall and 70.9 mm wide, housing a 5.8-inch OLED display. Lay an iPhone 11 protector over an iPhone X and it overhangs the screen by several millimetres on every edge — there is no way to centre it, align the notch cut-out, or get the adhesive to seal on a surface that curves away beneath it.
The details differ as well as the outline. The X’s OLED display has slimmer borders than the 11’s LCD, the two phones’ notches are not identical in proportion, and the corner radii don’t match. Even a theoretical protector in the right overall size would still need the right cut-outs — which is why protectors are always sold per model or per confirmed pairing, never per screen-size label alone.
What Happens If You Try Anyway
With tempered glass, the attempt usually ends at the fitting stage: the oversized sheet bridges across the X’s curved edges, the adhesive can’t bond around the perimeter, and you get a permanent white halo of unbonded edge that collects dust and eventually lifts. If a case goes on afterwards, its lip catches the overhanging glass and pops a corner up. A flexible film protector is more forgiving — it can be roughly centred and will cover the display — but the notch cut-out won’t line up, the edges extend past the flat part of the screen, and it will peel early. Either way, you’re paying protector money for a protector that doesn’t really fit.
- Already holding an 11 protector and an iPhone X? Don’t open it. X and XS protectors are among the most widely stocked sizes in the range, so exchanging is easy — and the correct one costs no more than the one you’re returning.
The Pairings That Actually Work
Both phones have an exact twin, and knowing them makes shopping simple. The iPhone X and iPhone XS share the same body dimensions and display size, so protectors are sold as combined X/XS listings and fit either phone perfectly. The iPhone 11 and iPhone XR likewise share a body, and their protectors are interchangeable. Cross those two pairs and nothing fits; stay within them and everything does.
One nearby trap deserves a mention: the iPhone 11 Pro is also a 5.8-inch phone, which tempts people to assume its protectors fit the X. They don’t reliably — the 11 Pro’s body is slightly different again at around 144 × 71.4 mm, with different proportions around the display. For an iPhone X, the listing you want says X / XS, full stop.
- When a listing claims to fit “iPhone X, XS, XR and 11” in one product, treat it as a red flag. Those are two different body sizes, so the protector has genuinely been cut for neither — buy the combined listing that matches your pair only.
Frequently Asked Questions
Does it work the other way — an iPhone X protector on an iPhone 11?
No. The mismatch is symmetrical: an X protector on an 11 is about 7 mm too short and 5 mm too narrow, leaving an unprotected border of screen on every side and misaligning the cut-outs. It would sit flat, unlike the oversized reverse swap, but a protector that doesn’t reach the edges isn’t doing its job.
Can I trim an iPhone 11 film protector down for my X?
A flexible film can be cut with scissors as an emergency stopgap, but the notch cut-out will still be in the wrong place and hand-cut edges lift quickly. Tempered glass cannot be trimmed at all — scoring or cutting it makes it shatter. Given how cheap and available X/XS protectors are, trimming is a false economy.
Will an iPhone XS protector fit my iPhone X?
Yes — this is the correct pairing. The X and XS share identical body dimensions and the same 5.8-inch display layout, so protectors listed for either phone, or as a combined X/XS product, fit both exactly. It’s one of the few genuinely interchangeable pairs in the iPhone range.
Close in age is not close in size: the iPhone 11 is simply a bigger phone than the iPhone X. Match the X with the XS, the 11 with the XR, and every protector will fit first time.
