Using a photo tape measure, you can measure the length and area of ​​other objects that are stamped together using a reference object of known size, such as a coin or A4 sheet.

✔ User Guide

① Select reference object

- Select the desired reference object from the menu on the top right. All objects are on the same plane, and the more pictures are taken perpendicular to the plane, the more accurate the measurements can be.

② Object length measurement

- After adjusting the size by increasing or decreasing the green shape on the standard object, click the Done (Check) button in the lower right corner. Now you can measure the length of an object through a line.

③ Object area measurement

Using the same method, you can now place a triangle, circle, or square on a photo to measure the area of ​​an object.
