How to Calculate Your Kua Number: A Complete Guide for 2026

by Mercer Hailee on Mar 05, 2026

In the world of Feng Shui, your personal Kua number (also known as the Gua number) is the key to unlocking a harmonious living environment. Whether you are redesigning your bedroom or optimizing your home office, understanding your Kua number allows you to align your furniture with your most auspicious directions. At wehomz, we believe that a well-designed home is not just about aesthetics—it is about creating a space that supports your energy and well-being.

What is a Kua Number?

Your Kua number is a unique digit based on your birth year and gender. It is derived from the Eight Mansions (Ba Zhai) school of Feng Shui. This number categorizes individuals into two groups: the East Group and the West Group. Each group has four favorable directions and four unfavorable ones. By knowing your number, you can position your bed, desk, and sofa to attract wealth, health, and success.

"The Kua number is essentially your personal energy blueprint. It tells you how you interact with the magnetic fields of the Earth." — Feng Shui Research Center [1]

How to Calculate Your Kua Number: Step-by-Step

Calculating your Kua number is a simple mathematical process. However, the formula differs slightly for males and females, and there is a specific adjustment for those born after the year 2000.

Step 1: Determine Your Lunar Birth Year

Feng Shui follows the Lunar calendar. If you were born in January or early February (before the Lunar New Year), you should use the previous year for your calculation. For example, if you were born on January 15, 1990, your birth year for this calculation is 1989.

Step 2: The Calculation Formula

For Males:

1.Add the last two digits of your birth year. If the result is a double digit, add them again until you get a single digit.

2.Subtract that single digit from 10 (if born before 2000) or from 9 (if born in or after 2000).

For Females:

1.Add the last two digits of your birth year and reduce to a single digit.

2.Add 5 to that digit (if born before 2000) or add 6 (if born in or after 2000).

3.If the result is a double digit, add them together to get a single digit.

Important Note: The Number 5

In the Kua system, there is no Kua number 5.

•If a male calculates a 5, his Kua number becomes 2.

•If a female calculates a 5, her Kua number becomes 8.

Applying Your Kua Number to Your Home Decor

Once you have identified your personal kua number and your birth element, you can start making strategic changes to your home. Here is how to use this knowledge with wehomz furniture:

1. The Bedroom: Better Sleep and Relationships

Your bed should ideally face one of your four lucky directions. For instance, if your Kua number is 1, facing North while sleeping can enhance your personal growth.

•Tip: Use a solid headboard from our [wehomz Bedroom Collection] to provide stability and support.

•Avoid: Placing your bed directly in line with the door, known as the "coffin position."

2. The Home Office: Productivity and Wealth

Position your desk so that you face your "Sheng Chi" (Success) direction while working. This is particularly important for entrepreneurs and remote workers.

3. Living Room: Harmonious Gathering

Arrange your seating to encourage positive energy flow. Use the Bagua map to determine which colors and materials best suit each corner of your living room.

Understanding Your Birth Element

Your Kua number is closely tied to your birth element (Water, Wood, Fire, Earth, or Metal). Incorporating these elements into your decor can further balance your home's energy.

•Water (Kua 1): Use blue tones, mirrors, and fluid shapes.

•Wood (Kua 3, 4): Incorporate plants and wooden furniture.
