Measure

Use your iPhone to determine whether an object near you is level, parallel to the ground, or how many degrees it varies from level. Measurements are approximate. It’s in the Measure app, and you’ll see green when the object is level.

1. Open the Measure app (in the Utilities folder) on your iPhone.
2. Tap Level. Hold iPhone against an object, such as a picture frame.
   • Make an object level: Rotate the object and iPhone until you see green.
   • Match the slope: Tap the screen to capture the slope of the first object. Hold iPhone against another object and rotate both of them until the screen turns green.

To reset the level, tap the screen again.

On supported models, you can save a list of all the measurements you take in a single session, complete with screenshots, so you can easily share and access them whenever you need them. They’re behind the History button in the Measure app.

1. Open the Measure app (in the Utilities folder) on your iPhone.
2. Tap the History button to see a list of your recent measurements.

   Swipe up from the top of the list to see more measurements.

3. To save the measurements, tap Copy, open another app (for example, Notes), tap in a document, and then tap Paste.

Note: Height measurements aren’t included in this list.

You can use your iPhone camera to measure nearby objects, automatically detect the dimensions of rectangular objects, or manually set the start and end points of a measurement.

On supported models, Edge guides help you measure the height and the straight edges of furniture, countertops, and other objects, and Ruler view shows more detail. While you’re measuring, a green dot appears to show that your iPhone camera is in use.

For best results, use Measure on well-defined objects located 0.5 to 3 meters (2 to 10 feet) from iPhone. (Measurements are approximate.)

Note: Measure works on external displays without turning on Screen Mirroring in Control Center.

Start a measurement

2. Use the iPhone camera to slowly scan nearby objects.
3. Position iPhone so that the object you want to measure appears on the screen.

Note: For your privacy, when you use Measure to take measurements, a green dot appears to indicate your camera is in use.

Take an automatic rectangle measurement

Use edge guides

On supported models, guide lines appear automatically, making it easy to measure the straight edges and height of furniture, countertops, and other objects.

1. Open the Measure app (in the Utilities folder) on your iPhone.
2. Position the dot at the center of the screen along the straight edge of an object until a guide line appears.
3. Tap the Add button where you want to begin measuring.
4. Slowly pan along the guide line. Tap the Add button at the endpoint to see the measured length.
5. To take a photo of your measurement, tap the Take Picture button.

Use Ruler view

Ruler view shows more detail in your measurements on supported models.

1. Open the Measure app (in the Utilities folder) on your iPhone.
2. After measuring the distance between two points, move iPhone closer to the measurement line until it transforms into a ruler, showing incremental units of length.
3. To take a photo of your measurement, tap the Take Picture button.

On supported models, you can instantly measure a person’s height from the floor to the top of their head, hair, or hat, and even measure a person’s seated height in the Measure app.

A line appears at the top of the person’s head, with the height measurement just below it, and you can take a photo of the measurement. You can access and share that image from Photos or Files whenever you want, and reset the height to take the measurement again.

1. Start the Measure app (in the Utilities folder) on your iPhone.
2. Position iPhone so that the person you want to measure appears on the screen from head to toe.

   After a moment, a line appears at the top of the person’s head (or hair, or hat), with the height measurement showing just below the line.

3. To take a photo of the measurement, tap the Take Picture button.
4. To save the photo, tap the screenshot in the lower-left corner, tap Done, and choose Save to Photos or Save to Files.

The height measurement image is available in Photos or Files on iPhone, so you can access and share it whenever you want.

To take the measurement again, reset the height by turning iPhone away for a moment.
