No, "the 13" isn't one size; the iPhone 13 lineup has four models (Mini, standard, Pro, Pro Max) with different sizes, though the standard iPhone 13 and iPhone 13 Pro share the exact same dimensions (6.1-inch screen, same height, width, depth), while the Mini is smaller and the Pro Max is much larger, with distinct dimensions and screen sizes.
The standard iPhone 14 has nearly identical dimensions to the base-model iPhone 13. Both devices stand 5.78 inches (14.68 cm) tall and measure 2.82 inches (7.16 cm) in width.
All cases in the X generation, however, are interchangeable, meaning an iPhone XR case should fit the XS. Similarly, iPhone 13 cases will fit the iPhone 14, as the two phones share the same height and width. However, this isn't the same the other way round, as the iPhone 14 is 0.01 inches thicker.
According to our research, the iPhone 14 measures 5.78” x 2.82” x 0.31” – almost identical to the iPhone 13. If you're upgrading from an iPhone 13, there's a good chance your case will fit. That said, the iPhone 14 boasts improved camera sensors, which slightly alter the size and placement of the camera module.
Only some older models truly match. iPhone 6 fits 6S, iPhone 7 fits 8/SE (2nd & 3rd gen), and iPhone X fits XS. Beyond these, differences in bump size and button placement make “almost fits” unsafe. Newer models like iPhone 14, 15, 16, and 17 share no cross compatibility at all.
However, the iPhone 13 is slightly thicker and heavier, with a depth of 7.65 mm compared to 7.4 mm. While this difference is minimal, it does mean that iPhone cases built for the 12 model are likely to be too tight for the 13, and therefore aren't compatible between generations.
No, it won't. While both phones have a 6.1-inch display, Apple made several small but important design changes that make older cases incompatible. The iPhone 15 has a more rounded shape, a larger camera bump, slightly different button placements, and a USB-C port instead of Lightning.
No, they can't. Regular 13 use LTPS screen while 13 Pro uses LTPO screen which enables Variable Refresh Rate. Just because they have same resolution and same cost to repair in Apple doesn't mean they're interchangeable.
Apple discontinued the iPhone 13 (and older models) to streamline its product line, focus resources on newer devices like the iPhone 16 series, simplify supply chains, and encourage upgrades to current, more advanced, and energy-efficient technology, following its typical annual product cycle. The iPhone 13, a 2021 release, was retired in September 2024 when newer iPhones were launched, making way for current models to occupy lower price points.
The iPhone 13 mini and iPhone 12 mini are the smallest iPhone models. Apple did not have a new small model ready for the September 2022 iPhone 14 release.

The iPhone SE (2022) measures 138.4×67.3×7.3mm, making it easy to hold one-handed, even if you don't have particularly big hands. The iPhone 13 mini is smaller still, measuring 131.5×64.2×7.7mm. But if you want the smallest iPhone, the iPhone 12 mini has the edge at 131.5×64.2×7.4mm.
The iPhone 14 retains the Super Retina XDR display offered on the iPhone 13, and both models get a 6.1-inch OLED screen with a resolution of 2532 x 1170 pixels.
While both devices offer smooth performance for everyday tasks, the iPhone 15 is better equipped to handle more demanding applications and games, thanks to its improved processing power and battery efficiency.
The iPhone 14 series continues with the flat-edge design, but dimensions and camera size variations need to be considered. An iPhone 13 case can fit an iPhone 14, but not vice versa due to the slight depth difference.
Compatible Cases
Some iPhones are similar enough to use the same case interchangeably: iPhone 6, 6S, 7, 8, and SE. iPhone 6 Plus, 6S Plus, 7 Plus, and 8 Plus. iPhone 12 & 12 Pro.
The iPhone 13, 12 and 11 all measure 6.1 inches - so basically exactly the same size. How much storage space does the iPhone 13 have? The integrated storage on the iPhone 13 is available in either 128 GB, 256 GB or 512 GB.
Unfortunately, the iPhone 12 and iPhone 13 cases are not interchangeable. Although they share similar height and width dimensions of 146.7-by-71.5 millimetres, the depth of the phones differs slightly, with the iPhone 12 measuring 7.4 millimetres, while the iPhone 13 is slightly thicker at 7.65 millimetres.
The iPhone 11 models are in general a bit larger than the 13 models so cases for the iPhone 11 may be a bit big on an iPhone 13, also, note the iPhone 11 has rounded sides, while the iPhone 13 has sharp square asides so iPhone 11 cases may not exactly fit the 13.
