How to measure someone’s height with the iPhone 12? “There is an app for that”, this was the theme of many ads that Apple published several years ago along with the first iPhones. The idea is that there were apps to do practically anything, even to measure someone? Sure, even to measure someone.
We all know the app Measure, it is the application that helps us measure our environment with amazing accuracy. This app is included with the operating system, so we all have it available on our devices.

The Measure app relies on the spatial awareness of the device to make measurements. In most devices, it is through the depth information that can be inferred from the different cameras, but in some devices, the system goes much further. Starting with the iPad Pro (2020) and continuing with the recently introduced iPhone 12 Pro and iPhone 12 Pro Max Apple has included a LiDAR sensor. This sensor allows the device to make highly accurate measurements of its environment up to about 4 meters away.
How to measure someone’s height with the iPhone 12?
To use this feature we need a device with a LiDAR sensor as the new iPhone 12 Pro, for example. After opening the Measure app we simply have to focus on the person we want to measure as if we were going to take a full-body photo. After a couple of seconds, we will see an indicator line appear at the top indicating us the height of a person.
Nothing else, it’s that easy. If we want to record that measurement, we can touch the shutter button on the screen to take a picture with the information of the measurement superimposed. As far as accuracy is concerned, in most cases, a single measurement with good lighting conditions and a good point of view is enough for accuracy to the centimeter.
This, like many others, is one of those small functions that Apple includes in their devices without announcing it in a big way and that makes a difference in the utility. It is easy to forget that they are there, but the next time our child asks us to check if he has grown, for example, we will only have to use our iPhone.
