3-in-1 Ruler

Three ways to measure when you don't have a measuring tape or ruler:

1 – AGAINST YOUR SCREEN
Simple and accurate, but limited to the length of your screen.

2 – IN AUGMENTED REALITY
Uses the new AR technology introduced in iOS 11. So far it only works on horizontal surfaces such as floors and tables. It won't work if your device cannot detect the surface. As this technology is still in its infancy, accuracy is variable.

3 – USING AIRPRINT
Print a ruler! Accuracy depends on the printer, so check the result against the on-screen ruler. An upcoming update will add a calibration feature.
