When choosing stair tread size, we should not only consider its aesthetics, but also its safety, so as to avoid too many gaps and sharp edges and corners in the design of villa stair tread size. There are strict and precise requirements for the step size of villa stairs. In general, the step size is 900mm, and the platform must be set at the 18 step, and the height of the step is generally170 mm. The vertical distance from the first step of the villa stairs to the top step is greater than 220mm, and the distance from the highest step of the stairs to the roof must be greater than 2000mm, so as to avoid feeling of depression. The height of handrails on both sides of stairs is 850-900mm, and the optimal diameter is 550 mm
Step width is also very important in the selection of stair step size, which must be strictly and accurately controlled and planned. Villa is different from ordinary commercial housing, and it has strict requirements on price and comfort. When choosing the size of the villa stairs, it must be beautiful.

In modern decoration, the size of villa stairs varies widely, which can be adjusted according to actual space and needs. Spiral staircase is a common decoration method for villa stairs. Spiral stairs are usually arranged in a circle around a single column, and the platforms and steps are fan-shaped planes. The inner width of stair steps is small, forming a steep slope, and the spiral staircase structure is complex. Spiral stairs are more space-saving in application, and the minimum step size of villa stairs can be 1300* 1300mm or1400 *100mm. However, because the spiral staircase has only one stress point, it has certain defects in structure and load bearing.
