For people who renovate buildings and villas, the design of stairs is very important. As the connecting area connecting the upper and lower floors, in addition to being beautiful, it must of course be convenient to use. So, what is the appropriate stair treads dimension?

What is the appropriate stair treads dimension

1. The slope of the stairs

Stairs design has a benchmark, at least to ensure smooth and comfortable walking, high efficiency up and down; in addition, the trend of the stairs and the connection of the space should also be paid attention to. To achieve the above standards, we have to look at the angle between the slope line (the line at the forefront of each step) and the horizontal plane. This angle is also called the slope of the stairs. Generally speaking, for normal indoor stairs, the slope of the stairs is about 20-45°, and the ideal slope is 30°, which is also the easiest slope for people to go up and down.

2. Step size

The step size of indoor staircase decoration is generally controlled between 180-200mm, and only the special needs of some public places will be designed as early as 130-160mm. We also need to look at the middle distance of the step, which is the so-called depth length. It is more appropriate to control it at 230-250mm, and the shortest should not be less than 220mm; if the length exceeds 300mm, it will be difficult to take the step. Therefore, if your home is a standard commercial apartment complex, it is recommended that the step height be set at about 170-210mm.

3. Width of stairs

The width of the stairs is the width of the passing stairs. For single-person traffic, generally, about 800-900mm is enough. In the case of home stairs, there is rarely a large flow of people, so there is no problem in controlling this width. If it is a staircase used in some public places, the width requirements will be larger, at least above 1600mm; wider sizes also exist, and the calculation model will increase according to the increase in the flow of people per share. Here is a reminder that when the width of your stairs reaches more than 1400mm, handrails should be installed for safety reasons; if there is too much traffic, handrails should also be installed in the middle of the stairs.

4. Handrail height

The height of the armrest is a point worth noting. According to engineering mechanics, the height is most suitable at the waist of an adult; the height is controlled at about 85-90cm, and the diameter of the armrest cannot be too small, about 5.5cm can be a good feel.

The above is about the home stair size and step size how much appropriate all content. In this paper, the relevant dimensions of stairs are considered based on the large environment. Therefore, everyone in the decoration of duplex stairs must be combined with the actual situation of their units to measure.
