Measure dimensions with iPad
On supported models, use the Measure app 
and your iPad camera to measure nearby objects and surfaces—you can manually set the start and end points of a measurement, have iPad automatically detect the dimensions of rectangular objects, and more.
For best results, use Measure on well-defined objects located 0.5 to 3 meters (2 to 10 feet) from iPad.
Note: Measurements are approximate.
Start a measurement
- Open Measure , then use the iPad camera to slowly scan nearby objects.
- Position iPad 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

Use edge guides
On iPad Pro 12.9-inch (4th generation and later) and iPad Pro 11-inch (2nd generation and later), you can easily measure the height and straight edges of furniture, countertops, and other objects using guide lines that appear automatically.
- Position the dot at the center of the screen along the straight edge of an object until a guide appears.
- Tap where you want to begin measuring.
- Slowly pan along the guide, then tap at the endpoint to see the measured length.
- To take a photo of your measurement, tap .
Use Ruler view
On iPad Pro 12.9-inch (4th generation and later) and iPad Pro 11-inch (2nd generation and later), you can see more detail in your measurements with Ruler view.
- After measuring the distance between two points, move iPad closer to the measurement line until it transforms into a ruler, showing incremental inches and feet.
