The iPhone has consistently been at the forefront of smartphone innovation, with its screen resolution playing a crucial role in its appeal.
Since its introduction in 2007, the screen resolution and display size on the iPhone has continued to improve with each new model. The very first iPhone launched with a 3.5-inch screen and a resolution of 320 x 480 pixels. At the time, this was quite impressive for a smartphone. However, over the years, Apple has steadily increased the iPhone’s screen resolution and size to keep up with customer demands, competition from Android phones, and improving display technologies.
Today’s iPhones have sharper, more vivid displays that make viewing photos, videos, and other media an exceptional experience. The jump to the Retina Display in 2010 marked a major advancement in iPhone screen technology. With each new model, tweaks were also made to the screen’s physical size, aspect ratio, pixel density, brightness, and color reproduction. Over time, these changes have drastically improved upon the viewing capabilities of that original 3.5-inch iPhone display.

In this article, we’ll take a look at how the iPhone screen has evolved since 2007. We’ll also examine the different resolutions, sizes, pixel densities, and other attributes of the displays used in each generation. This overview will provide perspective on just how much progress Apple has made in iPhone screen tech over the past decade.
The Ultimate Guide to iPhone Screen Resolutions and Sizes for 2024
Why Complete Understanding of Phone Screen Size & Resolution is Crucial for iOS Apps
Before we proceed, it is crucial to understand the specifics of iPhone screen resolutions and sizes and how they elevate your app design and development:
- Alignment with Specifications: Knowing the exact screen sizes and resolutions ensures that your app’s design aligns perfectly with the device it’s displayed on. This eliminates any awkward stretching or shrinking of elements.
- Adherence to Guidelines: Apple has strict app submission guidelines. Being well-versed in screen specifications ensures that your app passes the review process smoothly.
- UI and UX Goals: Understanding screen sizes helps you define your User Interface (UI) and User Experience (UX) goals. It ensures design consistency across different iPhone models.
- Visual Weight and Balance: Knowing the screen dimensions allows you to give the right visual weight to different design elements, making your app aesthetically pleasing.
- Enhanced User Experience: When your app’s design is optimized for various screen sizes, it naturally enriches the user experience. Elements are where they should be, and users don’t have to struggle with misaligned buttons or text.
- Device Adaptability: iPhones come in various models with different screen sizes and operating systems. Understanding these specifications helps your app adapt seamlessly to different device types.
Understanding Key Terms Involved in iPhone Screen Resolutions and Sizes
Before we get into details of iPhone screen resolutions and sizes, you must familiarize yourself with some key terms. These will serve as your guideposts, helping you navigate this comprehensive guide more effectively. Let’s get to it:
Points:
We don’t use inches or millimeters to measure size; we use points. Think of points as the yardstick for your digital creations, a unit that allows graphics to scale smoothly regardless of a device’s resolution.
To get a bit technical, one point (pt) equals 0.352778 millimeters, 0.0138889 inches, or 1.333 pixels. But here’s where it gets interesting: one pixel is roughly 0.75 points. One point on a standard-resolution screen is almost the same as one pixel.
However, when you are dealing with high-resolution screens, like those on many iPhones, one point can equal two or more pixels. This ensures that text and images appear crisp and clear, no matter the device.
Pixels Per Inch (PPI):
As for screen quality, PPI, or Pixels Per Inch, is a term you’ll often encounter. Similarly, PPI tells you how many pixels can fit into a one-inch line on your screen.
A high PPI count means your screen can display more detailed visuals, making images look sharp and vibrant. In contrast, a lower PPI will result in larger, fewer pixels, giving images a chunky, pixelated look.
Resolution:
Resolution is the metric that gauges the clarity and sharpness of an image displayed on your screen.
Resolution is the yardstick for determining the sharpness and clarity of an image on your screen. It’s expressed as a set of two numbers, such as 1920 x 1080, indicating the number of individual pixels aligned horizontally and vertically. The higher the numbers, the more detailed and vibrant the image will be.
Here’s a quick rundown of standard display resolution sizes:
| Type | Resolution (in pixels) |
|---|---|
| High Definition (HD) | 1280 x 720 |
| Full HD (FHD) | 1920 x 1080 |
| 2K or Quad HD (QHD) | 2560 x 1440 |
| 4K or Ultra HD (UHD) | 3840 x 2160 |
It’s worth noting that the screen’s physical size doesn’t necessarily correlate with its resolution. In other words, even phones with smaller screens can offer sharp picture quality, i.e., a high resolution. So, when you’re in the market for a new device, keep an eye on the resolution specs; they play a significant role in your overall visual experience.
Screen Size
When we talk about screen size, we’re referring to the physical dimensions of the display, usually measured in inches. The measurement is taken diagonally from the screen’s top left corner to the bottom right corner. The same principle applies here just like you’d measure a TV screen or computer monitor.
Understanding the screen size is the first step in ensuring that your app or content fits perfectly on an iPhone’s display. It sets the stage for everything that follows, from design elements to user interaction.

Pixels:
The term “pixel” might sound technical, but it’s a blend of two simple words: “picture” and “element.” Each pixel is the smallest unit of color that your device’s display can show. These pixels are made up of red, green, and blue subpixels that work in symmetry to create the colors you see.
Now, let’s put this into perspective. When a font size is described as being 12 pixels in height, it means that from the top of the letter to the bottom, it occupies a space of 12 pixels. The same concept applies to the width. So, the next time you come across a specification like “AxB pixels,” know that ‘A’ and ‘B’ represent the height and width in pixels, respectively.
The Evolution of iPhone Screen Sizes
The “large screen, small device” paradox encapsulates the modern mobile user’s dilemma. We crave expansive displays for immersive experiences, yet we don’t want to lug around a bulky device. This paradox has significantly influenced design trends in the smartphone industry, and iPhones are no exception.
Here are the display specifications of different iPhone models:
