iPhone 13 vs iPhone 14 Size: When Cases Actually Fit Both

The iPhone 13 and iPhone 14 look close enough that accessory shopping can become confusing: both standard models are 146.7 mm tall and 71.5 mm wide, and some major accessory makers sell a single product for both phones. But “same footprint” is not the same thing as “identical hardware.” The iPhone 14 is slightly thicker, and a case still has to match the camera opening, buttons, speaker and port geometry—not just the phone’s height and width.

That leads to a more useful answer than a blanket yes or no. Some iPhone 13 and iPhone 14 cases are intentionally cross-compatible, but you should not assume every iPhone 13 case fits every iPhone 14. The product listing is the deciding evidence.

The two standard models share height and width, not thickness

Apple lists the iPhone 13 at 146.7 mm (5.78 in) tall, 71.5 mm (2.82 in) wide and 7.65 mm (0.30 in) deep. Apple lists the iPhone 14 at the same 146.7 mm height and 71.5 mm width, but 7.80 mm (0.31 in) deep.

The difference in depth is only 0.15 mm. That is small enough that a flexible or deliberately engineered case can accommodate both models. It is also large enough that “the dimensions look the same” is not a safe compatibility rule for a rigid, tightly toleranced shell.

Weight does not help with fit, but it is another reminder that these are different devices: Apple lists iPhone 13 at 174 g and iPhone 14 at 172 g.

A shared case listing is stronger evidence than a dimension chart

The best evidence that cross-generation fit can work is not a ruler—it is a manufacturer taking responsibility for the fit. OtterBox currently sells its Symmetry Series for MagSafe under a single listing covering iPhone 16e, iPhone 15, iPhone 14 and iPhone 13. That does not prove every case is interchangeable; it proves that a case can be engineered and validated for both standard models.

This distinction matters when shopping older inventory. If a case page explicitly names both “iPhone 13” and “iPhone 14,” the shared listing is useful compatibility evidence. If the page names only one model, do not upgrade it to dual compatibility just because the basic dimensions are close.

The camera opening is where visual similarity can mislead you

A phone case is a three-dimensional alignment problem. The back opening has to clear the camera module, the side walls have to line up with controls, and the bottom cutouts have to leave the connector and speakers usable. A shell can slide onto a phone yet still be a poor fit if one of those areas is cramped or misaligned.

That is why the common “it snaps on, so it fits” test is too weak. A useful fit means the phone seats fully, the case does not bow, buttons remain predictable, the camera surround does not press against the lenses, and the bottom edge does not interfere with charging cables.

For a used or unbranded case with no trustworthy compatibility list, those details are more important than the nominal 6.1-inch display label.

Screen protectors have an easier compatibility problem

A screen protector does not wrap around the phone’s thickness or rear camera housing, so cross-model compatibility is less surprising. Belkin, for example, sells a TemperedGlass protector that explicitly includes iPhone 14, iPhone 13 and iPhone 13 Pro in one compatibility list.

That does not make all front glass universal. Edge shape, speaker treatment, sensor clearance and protector design still matter. The practical rule is the same: trust the exact model list on the accessory more than a generic “6.1-inch iPhone” description.

Do not extend this answer to the Pro, mini or Plus models

“iPhone 13 vs iPhone 14” is only clean when you mean the standard 6.1-inch iPhone 13 and standard 6.1-inch iPhone 14. The surrounding families contain different devices. An iPhone 13 Pro is not simply an iPhone 13 with a different finish, and an iPhone 14 Plus is physically much larger than the standard iPhone 14.

This is one reason accessory listings that say only “iPhone 13/14” deserve a second look. Confirm the full model name rather than inferring it from the generation number.

Check the phone model before buying clearance or secondhand accessories

If you are not certain which iPhone you have, Apple provides the model name in Settings > General > About. Apple’s iPhone information guide also explains where to find the model name, iOS version and model number.

This check is worth doing before buying old stock because “iPhone 13,” “13 Pro,” “14” and “14 Plus” can appear together in marketplace titles. A seller’s photo of the box is less useful than the printed compatibility list and your exact model name.

MagSafe does not erase the physical-fit question

Both iPhone 13 and iPhone 14 support MagSafe, but a MagSafe label answers a magnetic-accessory question, not the entire case-fit question. A case still needs the right shell geometry. If a magnetic case is sold for both models, the shared listing is doing two jobs: confirming the shell is intended to fit both phones and indicating the case includes the magnetic arrangement required for its advertised MagSafe use.

If you already own a MagSafe wallet, stand or car mount, check the case maker’s exact compatibility wording. Magnetic attachment can be present while the physical shell is still model-specific.

A five-point check for an iPhone 13 case on an iPhone 14

If you already own the case and want to evaluate it rather than buy another one, inspect the fit without forcing the phone into a rigid shell.

1. Seat the corners: all four should sit fully inside the case without visible bowing or a corner trying to lift out.
2. Press every side control: the case should not preload a button or make one unusually difficult to press.
3. Inspect the camera surround: the opening should clear the camera hardware rather than touching or crowding it.
4. Check the bottom edge: charging plugs should insert normally and the speaker/microphone openings should not be obviously obstructed.
5. Test the accessories you actually use: if the case claims MagSafe compatibility, try your charger, wallet or mount rather than assuming a successful snap-on fit proves the magnetic system is right.

Stop if the case needs unusual force, bows after installation or pushes against the camera area. Saving an older case is not useful if the fit creates constant pressure or compromises access.

The useful rule is narrower than “yes, they are the same size”

The standard iPhone 13 and iPhone 14 share the same listed height and width, while the iPhone 14 is 0.15 mm thicker. That near-match explains why reputable brands can sell certain cases and screen protectors for both phones. It does not justify treating every accessory as interchangeable.

For a new purchase, look for both exact model names on the manufacturer’s compatibility list. For a case you already own, check seating, controls, camera clearance, the bottom edge and any magnetic accessories. The phones are close enough to share some accessories—but the accessory maker, not the dimension table alone, should make that promise.
