Many families will record the height of their children at different stages on the wall. These marks have become the most precious memories of every family. We hope that this mark can be preserved and presented in an interesting form. Therefore, we designed a tape measure, recorded the height on the tape measure, and made the height its scale. When measuring other objects with this "height tape measure", the child's height becomes a unique measure for each family. "Height tape measure" makes memories lively and interesting. The tape measure looks like a triangular ruler, so it fits with the top of the head and the wall, allowing us to record height more conveniently. We also made the hook of the tape measure into a pedal that is more suitable for foot stepping. The height tape measure not only records the change of height value. When using them to measure other objects, our presentation of object data may be interesting, such as "this table is as tall as you were four years old".
