Apple has always astounded the world. It produces a wide range of products, including personal computers, smartphones, wearables, and accessories.
However, it is primarily reliant on its iPhones for its roaring financial success. Unlike Android, the iOS ecosystem appears to developers and customers alike to be somewhat closed and esoteric.
Despite this, iPhones have a large mass appeal and are very popular all over the world.
When it comes to designing, developing, and marketing mobile apps for iPhones, one must follow the standards, rules, and so on that are exclusive to Apple and its devices.
Today, we’re here to assist you with one part of it. We’ve prepared a list of iPhone screen sizes and resolutions.
This knowledge will assist you in making better design, development, and marketing decisions. So, let’s get started!

Have you ever submitted a social media photograph that looked OK on Facebook but was partially buried on Twitter and cropped on Instagram?
Have you ever come across a blog or video with shortened text or images?
If you replied “Yes” to either of the questions, you must already understand the significance of correctly scaled and personalized media, text, screen designs, and so on.
Understanding phone screen sizes and resolution becomes much more critical when designing mobile apps or content for smartphones.
Let’s talk about this before we get into iPhone screens in particular.
The significance of app design and development
Understanding screen sizes, resolution, and so on is critical for app design and development.
It can be beneficial in the following ways:
- Maintain compliance with design and development specifications.
- Continue to follow the app submission requirements.
- Define your UI and UX objectives and maintain design consistency.
- Give the design elements the appropriate visual weight and balance.
- With the correct design decisions, you may enhance and simplify user experiences.
- Adapt to various device types, screen sizes, operating systems, and so on.
The value of marketing and advertising
Understanding the complexities of phone screens is crucial for more than just developers.
It is also essential for marketers who want to provide their viewers with remarkable, inspirational, and user-friendly material.
It can assist mobile phone marketers and advertising in achieving the following goals:
- Audience segmentation based on demographics (device type, screen type, etc.)
- Create appropriate app store screenshots and preview videos.
- Create adjustable and personalized banners, creatives, films, and so on.
- Choose the best design schematics, typography, and so on for ad creatives.
- Determine the appropriate word and content density for various screens.
- Make the content more viewable and interactive.
According to statistics, the size of the screen might influence cart abandonment, and users are more likely to abandon carts on devices with smaller screens.
Understanding phone screen sizes and resolution is critical for all of the reasons stated above and more.
This is especially true for iOS devices and iPhones, which have a worldwide appeal and, unlike Android, do not have a dispersed and heterogeneous market.
Some terms to be aware of in this context
Before we begin discussing iPhone screen sizes, resolutions, and so on, let us first define the terminology that governs these specs.
Screen Size
Screen size is the physical dimension of the screen, which is commonly expressed in inches.
Smartphone screen sizes are calculated by measuring diagonally from the upper left-hand corner to the lower right-hand corner.
Pixel (px)
Pixel is a combination of the words “image” and “element.” On a display screen, it is the smallest visible color unit.
These colored pixels are made up of red, green, and blue subpixels. Every digital image is composed of a vast number of discrete pixels.
When we say that an element (for example, a font) is 12 px or 12 pixels tall, we indicate that the element occupies 12 pixels on the screen from top to bottom. The same is true for width.
As a result, the next time you see a specification that reads AxB pixels (where A and B are numerical numbers), remember that it represents the pixels’ height and breadth.

Point (pt)
Millimeters and inches are useful for measuring physical objects, but not in the digital realm.
Millimeters and inches are useful for measuring physical objects, but not in the digital realm.
As a result, we utilize points to quantify size. One point (pt) is equivalent to 0.352778 millimeters, 0.0138889 inches, or 1.333 pixels.
Pixels Per Inch (PPI)
The number of pixels (or dots in the case of DPI, which is used in print) that can be arranged in a line across one linear inch is referred to as PPI.
A screen with a high PPI will display more detailed graphics and a less pixelated or distorted image.
Resolution
The display resolution is the number of distinct pixels that can be displayed on the screen in each dimension. The following are the standard display resolution sizes:
- High Definition (HD): 1280 x 720 pixels
- Full HD (FHD): 1920 x 1080 pixels
- 2K or Quad HD (QHD): 2560 x 1440 pixels
- 4K or Ultra HD: 3840 x 2160 pixels
(Please keep in mind that the physical size of the screen has nothing to do with its resolution. Phones with smaller screens can also have sharp image clarity and great resolution.)
iPhone screen resolutions and sizes: A Quick Reference
The progression of iPhone screen sizes is well documented. iPhones, like Android smartphones, come in a variety of screen sizes, and display screen sizes have increased.
The “big screen, little gadget” conundrum affects mobile phone consumers. We demand sophisticated displays on small and portable devices, and this preference has influenced screen design developments.
The evolution of the iPhone appears to be following a similar pattern. Let’s look at an iPhone screen size comparison to have a better understanding.
The evolution of iPhone screen sizes
iPhones are classified into the following categories based on their screen size:
- 3.5 inches: iPhone 4S (2011), iPhone 4 (2010), iPhone 3GS (2009), iPhone 3G (2008), iPhone 2G (2007)
- 4 inches: iPhone SE (2016), iPhone 5S (2013), iPhone 5C (2013), iPhone 5 (2012)
- 4.7 inches: iPhone 8 (2017), iPhone 7 (2016), iPhone 6S (2015), iPhone 6+ (2014), iPhone 6 (2014)
- 5.4 inches: iPhone 13 Mini (2021), iPhone 12 Mini (2020)
- 5.5 inches: iPhone 8+ (2017), iPhone 7+ (2016), iPhone 6S+ (2015)
- 5.8 inches: iPhone 11 Pro (2019), iPhone XS (2018), iPhone X (2017)
- 6.06 inches: iPhone 13 (2021), iPhone 13 Pro (2021)
- 6.1 inches: iPhone 12 Pro (2020), iPhone 12 (2020), iPhone 11 (2019), iPhone XR (2018)
- 6.5 inches: iPhone 11 Pro Max (2019), iPhone XS Max (2018)
- 6.68 inches: iPhone 13 Pro Max (2021)
- 6.7 inches: iPhone 12 Pro Max (2020)
You may identify the screen size of your target audience by going through the list above. If you want to target consumers who have the most recent iPhone models, you must build for larger screens and higher resolutions (discussed below).
If your audience includes tablet users, you can look at the table on the twentyeightb’s page and acquire specifics for iPads.
Classification of iPhones based on resolution
Aside from screen size, iPhones can also be classed depending on physical resolution. This contains the following groups of devices that are still operational:

- 2340 x 1080 pixels: iPhone 13 Mini (2021), iPhone 12 mini (2020), iPhone 12 mini (2020)
- 2532 x 1170 pixels: iPhone 13 (2021), iPhone 13 Pro (2021), iPhone 12 pro (2020), iPhone 12 (2020)
- 2778 x 1284 pixels: iPhone 13 Pro Max (2021), iPhone 12 pro max (2020)
- 2688 x 1242 pixels: iPhone 11 Pro Max (2019), iPhone XS Max (2018)
- 2436 x 1125 pixels: iPhone 11 Pro (2019), iPhone XS (2018)
- 1792 x 828 pixels: iPhone 11 (2019), iPhone XR (2018)
(The above resolutions are in landscape mode.) Simply reverse the two numbers for portrait. For instance, 2340 x 1080 becomes 1080 x 2340.)
Aside from the models listed above, iPhone also had devices with screen resolutions as low as 1136 x 640 pixels, which was once considered typical. However, smartphones that correspond to this specification, such as the iPhone 5S and iPhone SE, are no longer widely used.
iOS submission requires an App Store screenshot.
The next stage is to submit the app to the app stores when it has been developed and built.
You must include screenshots from within the app when submitting an iOS app.
The Apple App Store has established specific screenshot sizes for each of its devices. The following are the size requirements for submitting app screenshots for the iOS app.

It is vital to know that the most important display sizes for iPhones are 6.5 inches and 5.5 inches, and Apple wants you to prioritize them.
If you don’t want to go to the trouble of creating screenshots for all of the sizes stated above, only generate for these two screen sizes based on the parameters listed above.
As long as you have screenshots for 6.5 and 5.5 inches, Apple will automatically scale them.
Most developers adhere to this usual procedure.
Furthermore, keep in mind that while you must post a minimum of four screenshots, the maximum limit for any app listing is ten.
How do you ensure that your app looks well on all iPhone screens?
The solution is straightforward: follow Apple’s instructions.
Before launching an app, Apple suggests developing universal designs and a storyboard in Xcode. It includes comprehensive guidance for building app designs that adapt to different devices and screens.
However, if you want a quick and easy solution, you can use no-code DIY app makers that come with pre-defined environments to create the app.
You may make apps for all types of iOS users here. As a bonus, some may let you test your app’s designs and functionalities on several iOS devices kinds before paying to publish.
