How Many Inches is an iPhone 12? A Comprehensive Guide

Wondering how big the iPhone 12 really is? You’re not alone! Many people want to know the exact dimensions of their devices, and the iPhone 12 is no exception. In this article, we’ll walk you through how to determine the size of the iPhone 12 in inches. Let’s dive in!

Step by Step Tutorial: Measuring the iPhone 12

Before we get into the nitty-gritty, let’s quickly go over what you’ll be doing. In this tutorial, you’ll learn how to measure the iPhone 12 to find out its size in inches.

Step 1: Find a Ruler or Measuring Tape

The first thing you need is a ruler or a measuring tape.

Once you have your measuring tool, you’re ready to move on to the next step. Make sure your ruler or tape measure is long enough to measure the iPhone 12 from one corner to the opposite corner diagonally. This is because the screen size is measured this way.

Step 2: Measure the Screen Diagonally

Now, place the ruler or tape measure at the bottom left corner of the iPhone 12 screen and extend it diagonally to the top right corner.

When measuring, be sure to only include the actual screen area — don’t include the bezels (the border around the screen). This will give you the diagonal screen size, which is how smartphone screens are typically measured.

Step 3: Convert the Measurement to Inches

If your measuring tool includes centimeters, you’ll need to convert the measurement to inches.

To convert centimeters to inches, divide the number by 2.54. For instance, if you measure 15 centimeters, that’s about 5.9 inches. This is a handy conversion to remember if you’re comparing phone sizes or shopping for screen protectors or cases.

After completing these steps, you’ll know the size of your iPhone 12 screen in inches. It’s a simple process, but it’s useful for a variety of reasons, whether you’re comparing phones or just satisfying your curiosity.

What Happens After Measuring

Once you’ve measured the iPhone 12, you’ll have a better understanding of the device’s size. This can be helpful when buying accessories, comparing it to other phones, or understanding how it will fit in your hand or pocket.

Tips for Measuring the iPhone 12

Here are some helpful tips to keep in mind when measuring your iPhone 12:

  • Make sure the screen is clean and clear of any obstructions.
  • Be precise with your measurements to ensure accuracy.
  • Measure twice just to be sure of your findings.
  • If using a measuring tape, ensure it is straight and not curved or bent.
  • Remember that the actual usable screen area may be slightly smaller due to the rounded corners and notch.
