Standard stair tread size?
The size of the steps should generally adapt to the size and stride of people's feet, and it is also related to the use function of different types of buildings. The dimensions of the steps include height and width. The height-width ratio of the steps is the slope of the stairs. Steps can have different values under the same slope, giving a suitable range, which makes people feel comfortable when walking.
Practice has proved that the steps that feel comfortable when walking are generally small in height and large in width. Therefore, when choosing the aspect ratio, a smaller height is appropriate for two dimensions of the same slope, because walking is more labor-saving than stepping with a large height and a large width. But pay attention to the width should not be too small, not less than 240mm, so as to ensure that the center of gravity of the foot falls near the center of the foot, and 90% of the center of gravity of the heel is on the steps. For adults, the minimum width of stair treads should be 240mm, and the comfortable width should be about 280-300mm. ..
National standard: the step height of public stairs is:160-170 mm. According to this standard, the comfortable height of ordinary cement-based stairs at home is about160 mm.

The height and width of each step of the same staircase should be consistent, and the size should not change irregularly, so as to ensure that the relationship between slope and stride remains unchanged.

Generally, the width of a single staircase should be 800-900mm, and the general finished staircase should be designed according to this width; But for public use? Stairs in places, such as: the width of stairs for two people should generally be1100 mm-1400 mm; Generally, the width of a three-person staircase should be 1650-2 100. If more people circulate, the width will increase by 550+(0- 150) mm per stream.
