Will an iPhone 15 Case Fit an iPhone 16?

May 14, 2025
Upgrading to the newest iPhone is always a thrill, but it also means kissing your old phone goodbye. As you trade in your iPhone 15, you may ask yourself, “Will my current case fit my new phone?” Not only would you save some money, but you’d get to continue sporting your favorite accessory.
If you need a new case for your new phone, we’re here to help. Find out if an iPhone 15 case fits the 16 and compare the two models.
Are the iPhone 15 and 16 the Same Size?
The iPhone 15 and 16 look very similar upon first glance, and they even happen to be the same size. However, despite identical dimensions, the iPhone 15 case doesn’t fit its successor. The new phone has a redesigned camera alignment and added buttons, meaning the cutouts on your old cover won’t align with your new phone.
Using your old case will restrict the use of the new camera and action buttons and cover the lower camera lens. A misaligned case leaves your new phone prone to scratches. Investing in a case tailor-made for the 16 will ensure your new phone stays protected while maximizing its features.
Will an iPhone 15 Plus Case Fit an iPhone 16 Plus?
At first glance, the iPhone 16 Plus looks nearly identical to the 15 Plus. Both phones have the same dimensions and matching screen sizes, but subtle changes to the design make the 15 Plus case incompatible with the 16 Plus.
Much like the base model, the 16 Plus features a redesign of the camera lens placement and the addition of the action and camera buttons. The redesigned button placement prevents the 15 Plus case from aligning with the 16 Plus.
If upgrading to the 16 Plus, purchasing a compatible 16 Plus case is best to protect your new phone and maximize its usability.
Will an iPhone 15 Pro Case Fit an iPhone 16 Pro?
Unlike the non-Pro models, the 15 Pro already has the action button and shares the same camera lens placement as the 16 Pro. Barring the new camera button, a 15 Pro case should accommodate most 16 Pro features. Unfortunately, this isn’t the case.
While the 16 and 16 Plus are the same size as their predecessor, the 16 Pro has a slightly larger height and width than its previous iteration, meaning you’ll struggle to put the old case on. Even if you get it on, the slight change in dimensions means the 16 Pro buttons won’t align with your 15 Pro case.
Upgrading to the 16 Pro will require a compatible case for added protection and access to every feature.
Will an iPhone 15 Pro Max Case Fit an iPhone 16 Pro Max?
Like the 16 Pro, the 16 Pro Max’s distinctive difference from its previous model is the addition of the camera button. However, the 16 Pro Max experienced a similar increase in dimensions as the 16 Pro. This size change makes the phone incompatible with a 15 Pro Max case.
Even the slightest changes to the 16 Pro Max’s dimensions mean the 15 Pro Max case will provide a tight fit at best, and even then, the shifts in button placement will hinder functionality. A new case is needed to enjoy the 16 Pro Max’s features and prevent scrapes and scratches.
What’s New in the iPhone 16 Design?
The iPhone 16’s updated look includes some new features. Most notable is an added side button that pulls up the camera quickly, making it much easier to capture fleeting moments.
The button also acts as a slider, allowing you to zoom in and out by gliding your finger over it. This added feature makes the phone feel like you’re using a DSLR camera, but it sits flush against the phone, so it won’t be uncomfortable to hold.
The 16 will also incorporate the action button, first introduced in the 15 Pro. This button replaces the mute switch above the volume buttons and allows users to customize it to perform a desired action.
Apple has tweaked the new phone’s build, making it thinner with an improved ceramic shield for a stronger screen. The new base model no longer features the diagonal camera placement on the 15 and instead implements a vertical one.
iPhone 15 vs. iPhone 16 Comparison
Size Dimensions
As previously mentioned, the size dimensions of the iPhone 15 and 16 vary. While the 16 and 16 Plus remained the same size as the 15 and 15 Plus, respectively, the 16 Pro and 16 Pro Max experienced a size increase.
Camera Placement
While the 16 and 16 Plus didn’t experience a size change, their camera placement is the main difference setting them apart from their previous generation. The 16 and 16 Plus have a vertical camera lens alignment, a shift from the diagonal alignment on the 15 and 15 Plus.
Button Alignment
The changes in size in the 16 Pro and 16 Pro Max affect where the buttons are placed on the phone, affecting compatibility with 15 cases. Non-Pro iPhone 15s don’t have an action button, meaning their cases won’t accommodate their newer counterpart.
In addition, all 16 models now have a camera button, which isn’t accommodated by any iPhone 15 case.
Frequently Asked Questions
Can the iPhone 16 Fit a 15 Case?
Despite being the same size, the iPhone 16 cannot fit a 15 case due to its design. The vertical camera layout interferes with the iPhone 15 case’s camera opening, and the old case doesn’t accommodate the new camera button, rendering it useless.
Final Thoughts
Unfortunately, the iPhone 16 won’t fit into a 15 case. However, upgrading to the 16 allows you to revamp your accessories and find the perfect case to fit your personality.
