What are the Differences Between iPhone 12 and iPhone 13 Cases

With the latest iPhone rolling out, loyal Apple fans are clamouring to see whether their current iPhone case is compatible with the newest model. Knowing your limitations can help you save a great deal of money and invest in other accessories instead. 

If you plan on getting the new iPhone 13 for yourself and are curious about whether you should buy a new case or stick to your old one, here is a quick guide for your reference. 

iPhone 12 and iPhone 13 Case Compatibility 

The iPhone 12 and iPhone 13 have several differences when it comes to their features. At first glance, you will notice that they seem similar in build and thickness. However, it is vital to take a close look at the specific dimensions to know whether a case will fit snugly on each device.  

Loose and ill-fitting cases present much higher risks for phones slipping out of them. If you want to make sure your iPhone case can be used on another phone, here are the dimensions of each iPhone as a point of comparison:

  • iPhone 12 Dimensions 

The regular iPhone 12 and iPhone 12 Pro come at 146.7 x 71.5 x 7.4 mm. The iPhone 12 Pro Max is 160.8 x 78.1 x 7.4 mm. 

  • iPhone 13 Dimensions 

On the other hand, the regular iPhone 13 and the iPhone 13 Pro are 146.7mm x 71.5mm x 7.65mm. The iPhone 13 Pro Max is 160.8 mm x 78.1 mm x 7.7 mm. 

From these dimensions, we can estimate that the iPhone 13 (both regular and Pro versions) are slightly thicker than their iPhone 12 counterparts by about 0.2mm. 

Do the Buttons Fit the Same Way? 

Aside from length, width, and height, it’s important to note whether the new iPhone model has the same physical buttons as the iPhone 12 and iPhone 12 Pro. As we know, most cases are moulded to accommodate common physical buttons such as the power keys and volume keys.  

Based on our first look at the iPhone 13’s design, we can estimate that the volume and switch silence buttons are slightly lower than older phones. It is very noticeable if you’re trying to squeeze an iPhone 13 in an iPhone 12 case.  

This is also noteworthy if you’re upgrading your phone from the iPhone 11 and the iPhone 12 Pro Max.

Other Possible Differences 

Aside from the size and dimensions, there are some other significant differences to keep in mind when switching from the iPhone 12 to the iPhone 13. Design-wise, there are a couple of other newly-located peripherals that you need to consider when choosing your phone case.  

One significant peripheral is the camera. The iPhone’s cameras have progressed significantly with each new iteration, stemming from mono-cameras to dual-cameras, and now, even three-lens cameras. If you plan on reusing an old iPhone X case, for instance, with the new iPhone 12, it wouldn’t be compatible because the camera lens slot is too small. 

For the iPhone 13, there is a difference in camera size, especially for the iPhone 13 Pro, which is much larger than the iPhone 12 Pro version.  


Making the upgrade from iPhone 12 to iPhone 13 doesn’t just involve new features and peripherals. You must consider the dimensions of the phone itself to know whether you should get a new case.
