How to measure the size?

  1. Two people: It’s best for two people to measure together. One person to take pictures and one person to measure.
  2. Ensure accurate measurements ! : The ruler is held tightly against the area to be measured!!!
  3. Easy to identify: Don’t let the camera get too close to the ruler when taking pictures or recording video.

We have also prepared a demonstration video below to guide you.

If you know how to label an image, then you can just label it.
