The Short Version

Step1

Open the Measure app

First of all, find the Measure app on your iPhone. By default, it’s in a folder named Utilities on your home screen.

Step2

Find the object in your viewfinder

Get the object you want to measure in your viewfinder, and once the iPhone has scanned its surroundings you can start to measure it manually.

Step3

Tap the Plus button when the white dot is at each end of the object

Position the white dot that rests in the middle of the screen first at one end of the object, tap the Plus sign, and then at the other end of the object, and tap Plus again. To save the image with its measurement, tap the shutter button at the bottom right of the screen.
