I heard that the length of curtains is particular. According to the Feng Shui layout, is it better for the indoor curtains to be floor-length or as big as the windows?

To be honest, I have been doing curtains for more than six years and this is the first time I have heard that the length of curtains is related to the Feng Shui layout.

The main function of curtains is to decorate the home. The length requirements are slightly different according to your preferences and living habits.

For example, some people like the curtains to be flush with the window sill, while others like to have floor-to-ceiling curtains. Some people like floor-to-ceiling curtains to be higher off the ground (5-6 centimeters to prevent them from being mopped and stained), while others like them to be 1-2 centimeters off the ground.

Home feng shui is generally related to the orientation of the house, the orientation of the windows, and the furnishings. It should have nothing to do with the length of the curtains.
