Standing and lying down at the same time to measure height is basically the same, but will not be exactly the same. Since standing and lying down are different positions, they are affected by many factors leading to slight differences in height, but overall they will not affect the measured height. Whether standing or lying down, basically you can judge a person’s height, under normal circumstances lying down is relatively higher than standing height measurement, because some people have a hunchback or spinal scoliosis, when standing height measurement will be affected to a certain extent, but lying down the spine can be restored to a straight state, the height will be relatively higher. When standing, there will be extrusion between the joint tissue, lying flat will not appear this situation, also lead to standing height measurement will be a little shorter. The difference in height measurement is caused by a certain bending of the body, in most cases standing or lying down will not affect the measurement of height, the height value is basically the same, there will not be a big difference.
