Feng Shui Dimensions for Double Casement Windows

In addition to determining the orientation and position of a window, the dimensions of a double casement window should follow Feng Shui principles to bring good luck to the homeowner. The window should also match the room’s size while ensuring optimal natural light and ventilation.

In Southeast Asian Feng Shui practices (including Vietnam), the recommended ratio between the window area and room area is 1:7. Additionally, the distance between the bottom and top edges of the window and the floor should be 0.83m – 2.2m. If the window falls outside this range, it may affect air circulation and energy flow, negatively impacting the household.

Feng Shui window dimensions (Lo Ban measurement):

• Height (m): 0.59 – 0.62 – 0.69 – 0.88 – 0.89 – 1.25 – 1.33 – 1.44
• Width (m): 0.47 – 0.61 – 0.66 – 0.85 – 0.89 – 1.08 – 1.25 – 1.26

Collection of Modern Double Casement Windows

Double casement windows are available in various materials such as aluminum-glass, wood, and iron. Wooden windows, made from natural wood, tend to be expensive and prone to termite damage and warping. Iron windows, on the other hand, can easily rust when exposed to environmental elements, affecting the home’s aesthetics.

Currently, aluminum-glass windows are the most popular choice. They offer several outstanding advantages that other materials lack, including resistance to warping, termites, shrinkage, and rust caused by weather conditions.
