What is the height of the hotel stairs?

The stair tread is 300mm wide and 150mm high, with a golden ratio, which is relatively moderate. But for public buildings, the width is more than or equal to 300mm and the height is 100mm- 150mm. The width of stair section in residence should not be less than 1 100 mm, and the width of stair platform should not be less than1100 mm. The net width of stair section should not be less than1.10 m. I hope my answer is helpful to you.
