If you own an iPhone, you can use its built-in features to measure various items accurately. In this article, we will explore how to measure with your iPhone and make your life more convenient.

Getting Started

To start measuring with your iPhone, you need to open the Measure app. This app comes preinstalled on iPhones running iOS 12 or later versions. If you cannot find it on your device, you may need to update your operating system.

Step 1: Open the Measure App

Unlock your iPhone and locate the Measure app on your home screen. The icon for this app resembles a ruler and a level combined. Tap on the icon to open the app.

Step 2: Grant Permissions

The first time you open the Measure app, it may ask for permission to access your camera. To ensure accurate measurements, allow the app to access your camera by tapping “OK” when prompted.

Taking Measurements

Now that you have opened the Measure app and granted necessary permissions, let’s dive into taking measurements using various features provided by the app.


The ruler feature allows you to measure straight lines or objects easily. To use it:

  • Step 1: Point your iPhone’s camera at one end of the object you wish to measure.
  • Step 2: Tap on the “+” button at the bottom of the screen to set a reference point.
  • Step 3: Move your iPhone along the object to measure its length. A yellow line will appear as you move.
  • Step 4: Tap on the “+” button again to set another reference point if you need to measure multiple segments of the object.
  • Step 5: Once you are done, the total length will be displayed on the screen.


The Measure app also includes a level feature, which can come in handy when you need to check if a surface or object is perfectly horizontal or vertical. Here’s how to use it:

  • Step 1: Open the Measure app and select the “Level” tab at the bottom of your screen.
  • Step 2: Hold your iPhone against the surface or object you want to check for levelness.
  • Step 3: Adjust your iPhone until both crosshairs align with each other, indicating that the surface or object is level.

Tips for Accurate Measurements

To ensure accurate measurements while using the Measure app, keep these tips in mind:

  • Avoid Shaky Hands: Hold your iPhone steadily and avoid any unnecessary movements while taking measurements.
  • Adequate Lighting: Make sure there is enough light in your surroundings for clear visibility of objects you are measuring.
  • Selecting Reference Points Wisely: Choose clearly defined points on objects as reference points for accurate measurements.

In Conclusion

The Measure app on your iPhone offers a convenient way to measure various objects without the need for a physical measuring tape. By utilizing the ruler and level features, you can accurately measure lengths and check for levelness.

Remember to follow the tips mentioned above for precise measurements. So, next time you find yourself in need of a quick measurement, reach for your iPhone and let the Measure app do the job!
