In Feng Shui, the orientation of the house is crucial, and choosing the correct size and placement of doors within the home is equally important. Experts recommend using a plumb bob for precise measurements, ensuring accurate door sizing for a properly designed, auspicious home. Here are some tips to help you in designing your home:

1. Door Characteristics
In Feng Shui, a good door helps homeowners welcome abundant positive energy, fostering prosperity and peace in their home. Here are some considerations to help you choose the most suitable door:
Consider making doors with the following characteristics:
-Opt for doors in spaces gradually narrowing from outside to inside, resembling a trumpet shape, allowing wealth to flow easily into the home. Choose doors of appropriate sizes to fit the room dimensions.
Ensure to pay attention to the size of your doors; overly small ones hinder airflow, while excessively large ones, no matter your wealth, lack durability and are hard to maintain.
Aspects of home doors to avoid:
Avoid positioning main doors in line with the centerline, the same applies to kitchen and restroom doors; the rear door should be smaller than the front one.
Avoid placing the house door at the end of a hallway or the gate at the end of an alley; this invites misfortune straight into your home, endangering the health of family members and leading to heightened stress and irritability.
A home should ideally have no more than 2 entrances and windows should align in a continuous line; this helps mitigate daily life inconveniences.
Maintain a window to door ratio of less than or equal to 3/1; as our elders say: the house door represents the voice of parents, while windows signify offspring. A ratio exceeding 3/1 often leads to conflicts and children challenging parental authority.
According to Feng Shui, an excess of windows in a house can lead to wealth depletion and asset loss.
For rooms like offices, it's advisable not to have too many windows; one main door and three windows are sufficient.
Windows should be smaller than doors; if larger, children may become stubborn, disobedient, disregarding parental guidance. However, you can install large windows with small panes to meet needs without violating Feng Shui principles.
