How to use the Measure app in on the iPhone, iPad

iOS and iPadOS come with a Measure app that allows you to draw (virtual) straight lines to measure objects and surfaces both vertically and horizontally using your iPhone or iPad camera.

iOS and iPadOS come with a Measure app that allows you to draw (virtual) straight lines to measure objects and surfaces both vertically and horizontally using your iPhone or iPad camera, and automatically detect dimensions of rectangular objects. 

To take a single measurement: 

° Open the Measure app, then follow any onscreen instructions that ask you to move your device around. This gives your device a frame of reference for the object you’re measuring and the surface it’s on. Keep moving your device until a circle with a dot in the center appears.

° Move your device so that the dot is over the starting point of your measurement, then tap the Add button.

° Slowly move your device until the dot is over the ending point of your measurement, then tap the Add button again.

After you take a measurement, you can adjust its starting and ending points. Touch and hold one of the points, then drag it where you want it to go. The measurement changes as you move the point.

Save your measurement

While the measurement is displayed, you can tap the number to see it in inches and centimeters. Tap Copy, and the value is sent to your clipboard so you can paste it into another app. Tap Clear to start over.

You can also take a photo that shows the object and its measurement. Just tap the Shutter button, and the photo appears in the lower-left corner of your screen. Tap it to make edits using Markup, or swipe left to save it to your Photos app.

To take multiple measurements:

° After you take the first measurement, move your device to place the dot over another location on or near the object.

° Tap the Add button to start the second measurement, then move your device to place the dot somewhere along the existing measurement.

° Tap the Add button again and the second measurement appears.

° Repeat these steps to take as many measurements as you’d like.

° Tap the Undo button (a reverse curve icon) to remove the most recent measurement, or tap Clear to start over.
