Free Kua number calculator

Feng shui for real homes. Start with your Kua number.

The bed has been against that wall since you moved in. Ten seconds tells you whether it is the right one: your Kua number names the four directions that support you and the four to handle with care. Free, and your birth date never leaves this page.

Birth date

Full date so we can handle the Chinese New Year boundary automatically. You don't need to look anything up.

Gender

Combining two people, for couples and shared rooms, is a free account feature. Sign in or create a free account to save your chart and combine two people.

Calculation runs in your browser. We never see your birth data.

Three days you already know.

A Sunday

The room that is quietly hard to be in.

The light is fine, the paint is fine, and still the ironing gets done somewhere else. Pick the room and get three moves for tonight. Free.

A September evening

The year feels like it has a shape.

You want to know which weekend not to start the bathroom, and which day to sign the thing that matters. The good days are listed, with the reason for each. Free.

The second time

You ran the chart for yourself, then for the person you live with.

Now you want to read it yourself and be right. The Four Pillars calculator draws the chart; the books teach you to read it.

Written by an architect. Labelled like a plan.

On an architect's drawing the door swing goes in before any furniture does. This site reads a home in the same order: door, then bed, then stove, then light, then where you sit when you work. Feng shui, underneath the schools and the cures, is that way of reading space: orientation, movement, light, proportion, entrance, rest.

Every recommendation here says which kind of claim it is. Better light helps you read: design-supported. The wealth corner and the mirror rules: traditional, and we say what the evidence supports. You keep the labels, and you keep the choosing.

This site exists so you can say why each thing in your home sits where it sits, in one sentence, to anyone who asks. Written by I.D., the architect behind My Feng Shui Home, from a library of twenty-three audited chapters.

The book written for your home

Your whole home, read as one system, with your name on the cover.

A bedroom tip from one place, a desk rule from another, a warning about mirrors from a magazine in a waiting room: put the three in one flat and two of them argue. Read as one plan, they stop. That is what the Complete Home Compass does, for your Kua.

The Complete Home Compass

Everything this site reads, in one book keyed to your birth date: all eight directions, all twelve rooms, all nine life areas, how your group pairs with another, and the year's chart against your Kua. Around 115 to 165 pages.

  • The verdict grid: nine life areas already read for your Kua, on one page, before you turn to the first chapter
  • Twelve room chapters, each ending on one move for tonight, marked when it needs no drill and no permission
  • Which corner of your home the year asks you to leave alone, and until when
  • Your name on the cover, in your inbox about a minute after you pay

One book, three depths, two ways in at the middle: the Twelve Spaces Compass, $79 reads every room; the Nine Life Areas Compass, $79 reads every life area; the Personal Feng Shui Compass, $29 reads your eight directions and the year. The whole map is above.

About you rather than your home: the Personal BaZi Reading draws your own chart and reads it to you, and The Birth Code teaches you to read it yourself.

Common questions

Do I have to redecorate?

No. Most useful feng shui moves are tiny. A clean stove. A bulb replaced. A bed turned ninety degrees so you can see the door. The 14-point checklist on this page is finishable in one afternoon and asks for no new furniture.

Is feng shui real?

Feng shui is real as a structured design method. It looks at where doors, beds, stoves, light, and people sit in a room, then proposes small changes. Some changes are testable design choices. Some are traditional. We name which is which on every page.

How is this different from a magazine article on feng shui?

Every recommendation here says which kind of claim it is: design-supported, traditional, applied observation, or preference. You get the design reading first, the tradition clearly labelled second, and a note on what the evidence supports. Then you decide.

Do I need to know my birthday for this?

Only if you want your Kua number, which keys the personal direction recommendations. The room pages and the 14-point checklist work without it. The Kua calculation runs in your browser, and anonymous use stays anonymous.

What is the Kua number?

Your Kua number is a single digit from one to nine based on your birth year and gender. It sorts you into an East or West group and names four directions that traditionally support you and four to handle with care. It takes ten seconds to calculate.

Is the site free?

The calculators, the guide, the methodology page and the room harmony checklist are free with no account. Saving a chart is free with an account. The books live on the shop page, and the free side of the site stays the same site forever.

What is the Personal Feng Shui Compass?

A book keyed to your Kua number: your East or West group, your four supportive directions and your four cautious ones, the traditional placements for the bed, the desk and the dining seat, a seven-day experiment, and the year's chart read against your directions. It reads your direction profile, not your floor plan. $29, one-time, no subscription.

What about Western feng shui versus Classical feng shui?

Both are used by working practitioners. Classical schools use a compass and birth data. Western BTB uses the front door as the reference. We teach the Classical Compass School (which produces your Kua number) and we link both methods in the methodology page.

Not what you hoped for? Email within 7 days and we make it right, up to a full refund to the card you paid with. Read the promise.

Ten seconds, and you know which wall the bed belongs on.

Scroll up and enter your birth date, or open the calculator on its own page. The result is free, it stays anonymous, and the choosing stays with you.
