Where is the most reasonable place to install a doorknob at home, perhaps many of our friends did not think too much about this issue, thinking that the impact would not be too big. Ying Yida Household Hardware believes that such negligence is unacceptable.

Here, Yingyida Household Hardware will share with you how to determine the installation position of the door handle.
The correct height for a doorknob is about the elbow
Before determining the installation position of the door handle, you must first confirm the most comfortable position for you when opening the door.

Therefore, the appropriate height of the door handle is near the elbow joint.
Generally speaking, the door in the house is not made for one person (except for lonely elderly, haha), so the principle of determining this height is to make it convenient for as many people as possible, so it depends from the height of the elbow joint. If the size distribution density is low, a site with the highest distribution density should be chosen. Generally, the 50th percentile is sufficient because human body sizes are roughly normally distributed. Here, it should be reminded that the height of the door handle should also include the size of the shoes, and the average shoe height for men and women is also different, and this must be carefully considered.
