How to Find the Right Smartphone for You: A Guide to Phone Size Comparisons

When buying a new smartphone, it can be difficult to know which size will be right for you. There are many different ways to measure a smartphone, including screen size, physical dimensions, weight and thickness. Before choosing the phone that’s right for you, it’s important that you understand how these sizes differ between smartphones. For more information on how to find the right smartphone for your needs, see this article.


  1. How to compare phone sizes

If you’ve been shopping for new smartphones, you’ve probably noticed that there are a lot of different sizes and screen resolutions to choose from. If you’re having trouble figuring out which phone to get, you can use this infographic from Mobiles .co in UK to help you compare phones. Mobiles .co UK is an independent, unbiased source for buying smartphones. All of their prices and specifications are based on real people that have tested phones for themselves. If an iPhone is too expensive for you, they have Android options to choose from.

There are two common types of screen diagonal measurement: Screen diagonal is the distance between the top and bottom of the screen. Height is the height of the screen measured vertically. Width is the distance between the top and bottom of the screen measured horizontally. Most smartphones are available with 3 different screen diagonal measurements.


  1. Phone size and screen size

There are two things to consider when it comes to screen size. The first is the physical size of your phone. The bigger the screen, the easier it is to see what’s on the screen. The second thing to consider is the screen resolution. The higher the resolution, the sharper the picture and the more vibrant the colours.

Because screen resolution is dependent on how much light is allowed to pass through it, phones with a very high resolution need larger screens to fit them all in. This usually translates to a larger form factor, usually by being wedged between larger phones like the Samsung Galaxy Note or the iPhone, or placed in a device body that does not allow easy access.

The average smartphone has a screen resolution of 960×540. In order for there to be enough room for all of the information on the screen, the size of the phone must be tailored to that resolution. For example, the 5.5-inch Galaxy Note has a 3,760×2,880 resolution and requires a device that is 3.6-inches wide by 6.4-inches tall to fit it all in without negatively impacting the device’s user experience.

  1. Screen resolution and pixel density

Screen resolution is the number of pixels on a device’s screen, and it’s typically measured in pixels per inch (PPI). It’s important to note that the higher the number of pixels, the crisper your screen will look. A pixel is one alleged independent colour pixel. For example, to select the “best screen size,” at My Precise we look at the PPI of a Samsung Galaxy S5. This 14-inch, Full HD (1,920 x 1,080) screen has a PPI of 600. To get a rough idea of the amount of detail on your screen, you can use an online tool such as Screen Size Grader, which you can find here.


  1. Understand your needs before you choose a phone

Before you make a purchase, you need to understand your needs. There are certain features you may need that take up a certain amount of space on the screen, which means you need to check what the screen size will be of that feature if you install that feature onto your phone. Screen size features include:

If you need to change the default size of your phone, it’s important to consider what other features are coming with your new phone. Check for any specs that are specific to the screen size that are important to you. These may include storage size, battery life, display resolution, camera resolution, refresh rate, and wireless technologies that make up your phone’s connection.
