In our modern world, smartphones can replace a wide range of gadgets and devices. The iPhone is able to perform the task of a measuring tape easily.

Measure on iOS 12 Pro and Pro Max can detect people and, using LiDAR, scan their height within seconds, whether they’re standing or seated. Apple’s iPhone 12 Pro and Pro Max smartphones offer a unique feature that makes it possible for a person to measure their height while standing up or sitting down. Even though this isn’t a feature you’ll use every day, it can be occasionally useful and is at the very least one worth exploring.

There were a number of exciting changes to the iPhone 12 when it was announced at the end of 2020. Most noticeable were the flat edges, contrary to the rounded edges of most other iPhones. It is easier to pick up and offers more tactile feedback. Two new iPhone sizes were also introduced, with the smallest iPhone 12 mini measuring 5.4 inches in size and the biggest iPhone 12 Pro Max, measuring 6.7 inches. In addition to being faster, having better screens, and supporting 5G, the newest models have bigger batteries. Its cameras, however, provided much better low-light photos, which was the most significant upgrade. In this article, we show you how to measure height with iPhone.

It is the only iPhone with LiDAR scanners, only found in the iPhone 12 Pro and Pro Max. A device like this can identify distances between surfaces within 16 feet of where the device is located. In addition to measuring the relative distance with great accuracy, Apple’s top iPhones utilize a technology that makes use of this technology. The Measure app is included on most newer iPhone models and is capable of offering the same functionality, but it requires good lighting and requires a short period of time to set up before use, which is done by waving the phone from side to side. On the iPhone 12 Pro and Pro Max, the Measure app can instantly assist you in measuring distances, which is no longer a problem. A unique feature that is only available in Apple’s Pro models is a feature meant specifically for measuring an individual’s height.

LiDAR: How Does It Work?

This type of camera measures time-of-flight. A smartphone camera measures depth using a single light beam. As a result, LiDAR sensors emit a spray of infrared dots in the form of waves of light pulses. The sensor measures each of them, leading to a field of points that can be used to map outdistances. This device measures the dimensions of the area or space and the items in it using these points. With a night vision camera, you can see them, but they are invisible to the human eye.

This sensor’s neat feature allows users to measure an individual’s height. The iPhone also offers the ability to measure length and height with its built-in LiDAR sensor, but the latest iPhones provide a more precise and accurate measurement, as well.

How to measure height with iPhone using the LiDAR Scanner?

LiDAR capabilities can only be accessed by specific devices. There is iPad Pro 12.9 inch (fourth generation), iPad Pro 11 inch (second generation), iPhone 12 Pro, or 12 Pro Max.

Measure the height of a person

  • Launch the Measure app.
  • If you are using your iPhone, make sure you can see the person from the ground to the top of their head so you can measure their height. A white line will appear above their head when they are automatically measured by the app.
  • To take a photo of the person alongside their height measurement, tap the circle in the lower-right corner of the screen.

Note: Make sure that you have good lighting and make sure that there are no reflective surfaces to help you get the best results. A face mask, sunglasses, or hat should also not be worn by the person being measured.

A ruler’s view

As its name suggests, the ruler view provides incremental measurements along a line, similar to what you would see when using a ruler. You can only access this feature if your device is equipped with LiDAR.

It is as simple as moving your device closer to the object you wish to measure in order to display the ruler overlay.

Guidance

With a LiDAR-equipped device, you will also be able to see vertical and horizontal guides when measuring. As a result, it can better understand what you are looking at by detecting the edge of objects.

Guides can be accessed by tapping the plus (+) icon.

History of measurements

You may find the measurement history useful when you are measuring multiple objects. On the left-hand side of the screen is a list button, using that you can find those. On top of that, you can see every screenshot you made while you were taking those measurements. 

If you choose to copy the measurement into your own notes app, you will be able to save them there as well.

Some Frequently Asked Questions by Users

1. What is the accuracy of the iPhone height measurement?

In spite of the fact that I had a lot of experiences, I found the precision really surprising, for it was almost to perfection; let’s call it a 99.9% accuracy. This app, Measure, turns your device into a tape measure through the use of augmented reality (AR). You can determine the height of the person who is standing in front of you with the help of LiDAR + AR.

2. Is it possible to check your height online?

An app called Height Ruler detects changes in air pressure on your device and calculates an object’s height using your device’s barometer. This allows you to conveniently measure any object with the help of a Height Ruler. To measure your height, for instance, you need to simply place your phone on the ground, then place your head on your phone, then return the phone back to the ground and this app will do the rest for you.

3. What is the best way to check my height on my phone?

Locate the plane by aiming your Phone at the foot of the subject and slowly moving your Phone. Once you’ve detected the starting point, touch it. Bring the camera to the subject’s full body by slowly lifting your phone. As soon as your phone identifies a face, it automatically displays the subject’s height.

4. How can I find out my height without measuring it?

In case you do not have a measuring tape, you can measure your height using a ruler. The person you ask to mark the wall above your head should stand up straight and have their back against the wall, as shown in the picture above. When measuring the distance from the floor to the mark with a ruler, make sure that you are using it correctly.
