Now more and more people start to choose marble stairs to decorate their houses, but safety is the most important thing and should be given priority in all aspects of home design. In terms of stair design, since the size and shape of the stairs in each space are different, the optimal size is also different.
1. Step height: The step height of ordinary stairs should be 15cm. If you are taller than 18cm, it is easy to feel tired when climbing stairs.
2. Step width: In general, the tread width is 27-30cm.
3. Step gradient: The indoor staircase gradient is generally 20°-45°, and the best gradient is about 30°. If there are elderly people or children at home, the suggested slope is 14°-27°.
4. Railing spacing: The stair railing spacing should consider the possibility of the child's head getting stuck, and pay attention to the distance that the child's head cannot enter or pass freely. The column spacing should be about 8cm, which can be adjusted according to your own needs.
