In this article, we will explore in depth How to use the Measure app on your iPhone and all its details, from its basic operation to its advanced features in devices with LiDAR sensorsWe'll also share helpful tips for improving measurement accuracy and how to get the most out of all its features.
One of the most interesting uses of the iPhone is its Ability to measure objects and spaces thanks to the Measurements app, a tool that comes pre-installed on the device and allows you to obtain dimensions with remarkable precision.If you've ever needed to measure a table, a door, or even a person's height, this app can be your ally without the need for a tape measure.
What is the Measures app and how does it work?
La app Size Use the iPhone camera to calculate dimensions in real timeUsing a combination of gyroscope, accelerometer, and augmented reality technology, the app analyzes the edges of objects and allows you to mark start and end points to obtain measurements with just a few taps on the screen.
On newer iPhones, especially those with a sensor LiDAR, the app is even more precise. This sensor It projects an infrared light beam that allows depth detection with greater accuracy, ensuring more reliable measurements.If you'd like to learn more about using the Measure app, keep reading this detailed guide.
How to measure with the Step-by-Step Measures app
To use the Measure app on your iPhone, follow these steps:
- Open the application Size on your iPhone. If you can't find it, you can search for it in Spotlight.

- Make sure the lighting is adequate to get an accurate measurement.
- Touch the button Add (+) on the screen to mark the start of the measurement.
- Slowly move your iPhone to the end point and tap again. Add.
- The measurement will appear on the screen. You can take a screenshot by pressing the shutter button.
- If you need a new measurement, tap Delete and start again.
Remember that if you encounter any problems or need help, there are resources available to resolve any questions you may have about using the Measures app to achieve better results.
Automatic measurements and object detection
One of the most interesting aspects of the Measures app is its ability to automatically detect rectangular objectsIf you frame a table, box, or any surface with well-defined shapes, the app will recognize its edges and show you the dimensions without you having to manually mark points.

Additionally, if you move your iPhone closer to the measurement, you'll be able to access a view of virtual rule, which will allow you to obtain even more precise details on small dimensions.
To use the app effectively, be sure to check out other useful apps for your iPhone. There are many tools that can complement Measure's functionality, including devices to improve your digital quality of life.
Measure a person's height with iPhone

If you have an iPhone 12 Pro or later with a LiDAR sensor, the Measure app also lets you measure a person's height automatically. To do this:
- Make sure the person is fully visible to the iPhone camera.
- The app will detect your presence and display a line above your head indicating your height.
- You can take a screenshot to save the information.
Advanced features on LiDAR devices
iPhones and iPads with LiDAR sensor offer advanced features within the Measures app. Some of the most notable are:
- Greater precision in measurements, thanks to depth detection.
- Automatic guides to mark straight lines more easily.
- The view of virtual rule to obtain measurements with more detailed increments.
To improve accuracy when using LiDAR, it is recommended to position yourself at an appropriate distance from the object and ensure that there are no obstructions in the measurement.

Tips to improve measurement accuracy
To get the best results when using the Measure app on your iPhone, keep these tips in mind:
- Make sure that the ambient lighting is suitable for improving edge detection.
- Clean the camera before measuring to avoid errors in reading.
- If the automatic measurement is not accurate, try do it manually, marking the start and end points.
- To measure large objects, move the iPhone slowly and follow the instructions on the screen.
- If the measurement is not correct, use the option undo to delete the last action and try again.
The iPhone's Measure app is an incredibly useful tool for those who need to take measurements without relying on physical instruments. Whether measuring furniture, checking a person's height, or simply effortlessly calculating distances, this app makes the task easier with remarkable accuracy, especially on devices with a LiDAR sensor. By following the right tips and taking advantage of its advanced features, quick and reliable measurements are possible at any time.
