The iPhone has some features in store that you don’t know about. Such as the possibility of using the so-called LiDAR sensor to measure body height. Here we show you how this exclusive feature works for the Pro and Pro Max versions of the iPhone 12 and iPhone 13.
Using a LiDAR scanner: measuring height with the iPhone
Some time ago, in another post, we showed you how you can create 3D scans of your own living room using the LiDAR sensor and a free app. In this article, we want to draw your attention to a useful iPhone feature that also uses the LiDAR scanner in the iPhone 12 or iPhone 13 (Pro/Pro Max) and for which you don’t have to download an extra app. You can use the pre-installed iOS “Tape Measure” app to measure height. This works completely automatically and all you have to do is start the app. It’s best to just try it out. The measurement results are quite accurate, as our test has shown.

To do this, proceed as follows:
- Open the “Tape Measure” app on your iPhone.
- Now the person whose height you want to measure must be visible in full – i.e. from the floor to the top of the head – in the live camera image. You may have to remove yourself a little from the person.
- If everything is correct, the measurement is carried out automatically and the result is displayed in the camera view. For the most accurate readings, you should avoid wearing a hat.
LiDAR: What was that again?
LiDAR (or “Light Detection and Ranging”) is a technology only available on the Pro and Pro Max versions of the iPhone 12 and 13 series. Broadly speaking, the system emits light and uses lasers to measure how long it takes to return to the sensor. Similar to a radar only with lasers instead of radio waves. In this way, the distance to certain objects or even their size can be determined. But the LiDAR sensor is also used for 3D models of objects using special apps and for measuring rooms and in augmented reality apps.
