Party Trick: Newer iPhones Allow You to Measure Someone's Height Instantly - MacRumors

iPhone 12 Pro and Pro Max, iPhone 13 Pro and Pro Max, and iPhone 14 Pro and Pro Max models feature a LiDAR Scanner next to the rear camera that can be used to measure a person's height instantly in Apple's preinstalled Measure app.

To measure a person's height, simply open the Measure app, point your iPhone at the person you want to measure, and make sure they are visible on the screen from head to toe.

After a brief moment, a line should appear at the top of the person's head with their height measurement.

You can even measure the seated height of a person in a chair.
