Do you want to get accurate measurements using your iPhone? With the Measure app, you can easily measure objects and spaces around you.

Whether you need to measure the length of a table or the dimensions of a room, this app is a handy tool to have. In this tutorial, we will guide you through the steps of using Measure on your iPhone.

Step 1: Open the Measure App

First, locate and tap on the Measure app icon on your iPhone’s home screen. The app icon resembles a ruler on a yellow background.

Step 2: Grant Access

Next, when prompted, grant access to your camera so that the app can scan and measure objects accurately. Tap “OK” or “Allow” if asked to give permission.

Step 3: Align Your Device

Now, hold your iPhone in front of the object or space you wish to measure. Align your device so that it captures the entire object within the frame. For best results, hold it steady and parallel to the object.

Tips for Accurate Measurements:

  • Avoid tilting: Keep your device straight and avoid tilting it while measuring.
  • Avoid obstructions: Ensure there are no obstructions like furniture or hands blocking your view of the object.
  • Favor good lighting: Well-lit environments help with accurate measurements, so try to measure objects in bright areas.

Step 4: Start Measuring

To start measuring, tap on the ‘+’ button at the bottom of the screen. Then, position the white dot at the starting point of what you want to measure and tap the ‘+’ button again to mark it.

Step 5: Complete Your Measurement

To complete your measurement, move your device along the object’s edge or space you wish to measure. As you move, a yellow line will appear, showing the measurement in real-time. Tap the ‘+’ button whenever you need to mark a specific point.

Step 6: Review and Edit Measurements

If needed, tap on any measurement on your screen to view additional details. You can adjust or delete measurements by dragging them or using the ‘x’ button that appears next to each measurement.


The accuracy of measurements may vary depending on various factors such as lighting conditions, device positioning, and camera quality.

Congratulations! You have now learned how to use Measure on your iPhone.

This convenient app can be a valuable tool for measuring objects and spaces accurately. Whether you are renovating your home or simply curious about dimensions, Measure makes it easy to get precise measurements right from your iPhone.
