Measure dimensions with iPhone

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.

A screen showing the measurement of the dimensions of a box in the Measure app. The area of the box is calculated from the measurements of the dimensions.

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: You can use Measure on external displays without turning on Screen Mirroring in Control Center.

Start a measurement

  1. Go to the Measure app (in the Utilities folder) on your iPhone.

  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 at the top of the screen to indicate your camera is in use.

Take an automatic rectangle measurement

  1. Go to the Measure app (in the Utilities folder) on your iPhone.

  2. Use the iPhone camera to slowly scan nearby objects.

  3. When iPhone detects the edges of a rectangular object, a white box frames the object; tap the white box or the Add button to see the dimensions.

  4. To take a photo of your measurement, tap the Take Picture button.

Take a manual measurement

  1. Go to the Measure app (in the Utilities folder) on your iPhone.

  2. Align the dot at the center of the screen with the point where you want to start measuring, then tap the Add button.

  3. Slowly pan iPhone to the end point, then tap the Add button to see the measured length.

  4. To take a photo of your measurement, tap the Take Picture button.

  5. Take another measurement, or tap Clear to start over.

Use edge guides

On supported models, you can easily measure the height and straight edges of furniture, countertops, and other objects using guide lines that appear automatically.

  1. Go to 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, then 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

On supported models, you can see more detail in your measurements with Ruler view.

  1. Go to 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.
