3 Fits of iPhone Screen Protectors (and WHY screen damage occurs even with protection!)

screen repairs are getting expensive. quality protection is important!

What good is a smartphone when you can't look at its screen properly? (That broken wire irks us as well!)

In our previous post, we highlighted that screen repairs are costly. As an proud owner of an iPhone 7 or iPhone 7 Plus, how do you protect your precious screen?

In this post, we will be sharing the pros and cons of the common screen protector "fits" in the market now. Yes, there are different sizes available, just like your clothing!

1. 2.5D Screen Protector - The Cheapest and Most Commonplace

2.5D iPhone screen protector

You will always notice the edges of a 2.5D protector (and feel it too!)

The 2.5D fit screen protector is the most commonly found in the market. To put it simply, it is just a flat piece of tempered glass without the curved edges. The screens of the iPhone 7 series are slightly curved on the edges. This means that 2.5D screen protectors are unable to cover the full screen as this would mean it will not be adhered securely to the screen. However, as a result of cutting the screen smaller than it needs to be, the 2.5D fit is almost guaranteed to fit most phone cases.

So instead of covering the entire screen, the 2.5D screen protectors only cover a limited area. Looking at your screen is not as great as it could be. Most of you would probably prefer to go without the protector, if not for fear of drops. Dust and dirt can also accumulate over time in the leftover screen space.

If you have heard of horror stories where the impact damage goes through the protector, chances are they may have been using 2.5D protectors. As you can never guarantee the angle of impact, there will be a chance that the contact point is the unprotected portion of your screen. However, many still use this kind of screen protector as it is the cheapest and most commonplace in the market. 

3. 3D Full Coverage Screen Protector

Believe it or not, there's a screen protector here!

3D Full Coverage screen protectors are an upgrade to the old 2.5D. These screen protectors cover your entire iPhone screen, with cut-outs for the camera, sensors and the home button. As you can see above, the screen protector blends seamlessly with your phone so you can barely tell the difference from your actual screen. Edge-to-edge screen protectors are perfect for those who desire a great aesthetic and better protection coverage. However, a common issue faced is the actual dimension of the glass. Not all glass are produced equal. Different brands have different dimensions. Some products are just not meant to be used with tighter cases, and will literally pop out when you use both at the same time.You will only be able to use one or the other. Bummer!

It is also noteworthy that the glass quality can differ, and so does the composition of the protection. While Invul protectors are 100% glass, other brands may use "carbon fiber" (as claimed) which is softer, more flimsy and not as protective against drops. The "glass" portion at the screen area is glued onto the carbon fiber layer below. It is also entirely possible that lousier adhesives were used to accomplish this combination, making it a bad experience overall for the user. This was one of the factors which drove us to find a better solution and hence, Invul.

When searching for 3D full coverage protectors, always ensure you understand what the protector is made of.

 4. 4D Full Coverage Screen Protector

4d full coverage protectors. Same same but different?Same, but different.

As manufacturers try to improve their technology, they have to give a better name to their products. The concept behind 4D is that the edges of the glass protector are curved even more than 3D. However, most manufacturers fail to achieve this. What is achievable however, is perhaps a higher glass quality or composition. It is once again noteworthy that quality differs between brands. One may be selling a far better 3D full coverage protector than the other, despite having the same specifications on paper (Japanese Asahi glass, 9H hardness etc.).


We hope you've gained a better understanding of the different fits of tempered glass screen protectors. As iPhone users ourselves, we were frustrated with finding consistent quality protection at an affordable price, which led us to the conception of our brand, Invul. Technology is always evolving, but we aim to establish great value for each of our customers. You may understand more about our products here!
