Door handle height standard

Many people like to choose brass door handles and antique door knobs in the decoration, but they do not clearly understand the installation height of the door handle, there is no fixed unified standard. But in our life, the height of the common door is generally between 180-200cm, and the height of the door handle from the ground is generally 110cm. The height of some door handles may be higher.

Door handle height selection

When we determine the door handle height, the first thing we should consider is the comfort that users need. The principle of door handle is a lever principle. The fixed point on the wall is the fulcrum, and the hand force is used as a point. The lever has three points: force point, fulcrum and resistance point. When the distance from the point of force to the fulcrum is greater than the distance from the resistance point to the fulcrum, it is not labor-saving or laborious when the distance from the force point to the fulcrum is equal to the distance from the resistance point to the fulcrum. When the distance between the force point and the fulcrum is less than that from the resistance point to the fulcrum, it is laborious. The handle can hold, operate or move mechanical equipment and cabinet equipment (mostly on the door), and is convenient for door opening, such as handle, armrest and other metal handle. Generally speaking, it should be most comfortable when the forearm is horizontal. Because at this time, the forearm and wrist joint only bear tension, there is no additional force of bending and twisting. It is the most economical from the mechanical point of view, that is, the appropriate height of the door handle should be the height of the elbow joint. Generally, it is enough to choose the 50th percentile, because the human body size is approximately normal distribution. The height of cupboard door handles and cabinet door handles should also follow this principle.

 

 

Other factors

When we install the door handle, sometimes we need to consider many aspects comprehensively. The size of shoes should be included in the design of door handle height, and the average value of additional height of men's and women's shoes is also different, which should be carefully considered. If there is no child in the family, the appropriate height of the door knob is about 1000mm. But if there are children in the family, we should consider setting the door handle height between 800-850mm.
