Three ways to measure when you don't have a measuring tape or a ruler: 1 – AGAINST YOUR SCREEN Simple and precise for small measurements. 2 – IN AUGMENTED REALITY Place a virtual measuring tape on a vertical or horizontal surface, such as a wall, table or floor. Built with ARKit. 3 – USING AIRPRINT Print a ruler! Accuracy depends on the printer, so check the result against the on-screen ruler.
