Front Door Feng Shui by Kua Number: Find Your Best Direction
Compass directions and element colors are useful, but feng shui also has a personalized system that's tailored to you: the Kua number from Eight Mansions feng shui.
The short answer: your Kua number (calculated from your birth year and gender) gives you four "auspicious" directions and four "inauspicious" ones. You can't rotate a house to match them, but you can use them to orient the things you do control — like where you sit, which entry you use, and how you arrange the doorway.
Here's how it works.
What the Kua number tells you
Eight Mansions feng shui divides people into two groups — East and West — based on their Kua number, and gives each person four favorable directions and four unfavorable ones. The most important favorable direction is sheng chi, the "success" direction, which practitioners align with the front door, the desk, and the bed.
The four auspicious directions, in order of strength:
| Direction | Name | Best for |
|---|---|---|
| **Sheng chi** | Success | Career, prosperity, the front door |
| **Tien yi** | Health | Recovery, vitality, the bedroom |
| **Nien yen** | Relationships | Love, family harmony |
| **Fu wei** | Personal growth | Stability, inner peace |
Each has a compass direction unique to your Kua number. Get your number first — run your birth year through the Kua number calculator to find all four.
Applying it to a front door you can't move
Here's the honest limitation, stated plainly: you cannot rotate your house. If your front door faces a direction that isn't your sheng chi, that's not a failure — it's just reality, and feng shui has always accepted it.
What you can do with your Kua number at the entry:
| What you control | How to use your Kua direction |
|---|---|
| Which entry you use | Use a side or back door facing your sheng chi as your main door |
| Where you stand to greet guests | Position yourself facing your sheng chi direction |
| The doormat's design or orientation | A subtle nod to your lucky element's color |
| Where the entry mirror points | Angle it toward your sheng chi direction |
The most practical use is the first one: if you have multiple doors, favor the one that faces your sheng chi direction as your daily entrance. It costs nothing and aligns your routine with your number.
Match your door color to your Kua element
If you want to layer color on top of direction, use your Kua number's element to pick a door color. Each Kua number maps to one of the five elements:
| Kua numbers | Element | Supportive door colors |
|---|---|---|
| 1 | Water | Black, deep blue |
| 2, 5, 8 | Earth | Beige, tan, terracotta |
| 3, 4 | Wood | Green, teal |
| 6, 7 | Metal | White, gray, gold |
| 9 | Fire | Red, orange, purple |
For the full element-color logic, see our front door color guide. The two systems stack cleanly: pick a color you like from your Kua element's range.
What NOT to do
- Don't remodel around a compass reading. If aligning with your sheng chi direction makes the entry worse — cluttered, dark, awkward — the approach always loses. See our door direction guide for what matters more. - Don't obsess over the inauspicious directions. They're warnings, not curses. Knowing them just tells you where to spend less time, not where to panic. - Don't skip the fundamentals for the personalization. Kua is a refinement layer on top of a clear, working mouth of qi — not a replacement for it. Get the basics right first (our mouth of qi guide).
The bottom line
Your Kua number is feng shui's personalization layer: four directions tuned to you. Use it to pick which entry you favor, where you stand, and what color you paint — not to move walls.
The beauty of the Kua system is that it works even when you can't change the house. A door you can't rotate, a color you can choose, a routine you can adjust — those are all levers you already control. Find your four directions, apply the one or two that fit your real layout, and move on. Start with the Kua number calculator to get your number in under a minute.
