According to the anti-discrimination law, companies should not make employment decisions based on irrelevant characteristics such as height, gender and race. Therefore, from the legal and moral point of view, the company should not take a person's height as the only or main criterion for employing people.

But some positions may require a certain height to be competent, such as athletes, models, special forces and so on. At this time, companies can consider the height factor. But in this case, the company should evaluate the applicant's qualifications according to the skills and abilities required for the position, rather than simply taking height as the sole or main criterion.

Therefore, if the company considers the height factor in hiring decision, it must ensure that the standard is related to the job requirements of the position and will not discriminate against shorter people.
