In villas or many loft apartments, duplex apartments, stairs are needed as the connection. Modern people pursue beauty and avant-garde while paying attention to the design of the dimension of indoor stairs which must conform to the principle of ergonomics. So today, OPPEIN is going to talk about the suitable design of dimension of indoor stairs.
Design of dimension of indoor stairs: slope
The slope of a stair has a standard. It not only ensures smooth and comfortable passing, but also provides efficiency and safety. Therefore, the important factor of stair slope is the angle between the slope line (the line at the front of each stair) and the horizontal plane. This angle is what we often call slope. Generally, the gradient of indoor stairs is about 20-45 degrees, which is the easiest gradient for people to go up and down the stairs.
Design of dimension of indoor stairs: handrail height
According to the engineering mechanics, the height of the handrail is the most appropriate when it is up to the waist position of an adult. The height is about 85-90cm; the diameter of handrail should not be too small. 5.5cm can give users a good feel.
Design of dimension of indoor stairs: step
The steps of indoor stairs are generally 180-200mm. But there are also special sizes for public places that are 130-160mm. The suitable middle distance of steps we often mention in design of dimension of indoor stairs should be 230-250mm, no less than 220mm. If the length is more than 300mm, it will be hard to walk. It is noted that the step height of the standard commercial duplex apartment is about 170-210mm.
Design of dimension of indoor stairs: width of stair flight
The width of stair flight refers to the width of the stair top, which is generally about 800-900mm for single person. In general, there is seldom a large flow of people in the family, so there is no problem with this width of stair flight unless your family has special requirements for the width of this flight.

What is the suitable design of dimension of indoor stairs? Stair design is a key step for many families living in villas and duplex apartments. As a "bridge" connecting the upstairs and downstairs, it is not only beautiful but also enjoyable to use. We hope the above reference of dimension of stairs can help you.
