Welcome to the Feng Shui Ruler Calculator, a unique tool designed to help you measure the auspicious and inauspicious lengths of your doors, furniture, altars, and home structures — based on the ancient Luban Ruler (Feng Shui Ruler).
In traditional Feng Shui, every inch carries meaning. The Feng Shui Ruler helps you ensure that your doors, windows, beds, tables, cabinets, and even photo frames fall within auspicious measurement ranges — attracting prosperity, health, success, and happiness to your home.
What Is the Feng Shui Ruler?
In Feng Shui, the Luo Pan ruler, Luban Ruler (also known as the Feng Shui ruler) is used to measure furniture, doors, altars, or rooms to ensure their dimensions fall within auspicious ranges. These measurements determine whether a size attracts wealth, health, prosperity, or misfortune.
It divides measurements into auspicious (lucky) and inauspicious (unlucky) sections, each representing different life energies — wealth, harmony, authority, illness, or misfortune.
By aligning your furniture, doors, and structural dimensions to auspicious lengths, you help energy (Chi) flow smoothly, creating a balanced and prosperous environment.
The traditional Feng Shui ruler is divided into 8 main sections, each representing a specific type of energy — positive or negative. These sections repeat every 17 inches (approx. 43 cm), making it easier to apply in both imperial and metric measurements.
The ruler helps you find favorable measurements when designing or choosing:
- Main doors and windows
- Tables, cabinets, and beds
- Altars, safes, or wealth boxes
- Architectural layouts and décor

Why Measurement Matters in Feng Shui (Not Just Design)
In Feng Shui, measurements are not taken only for visual balance or construction accuracy. Every measurement carries a specific energy quality that can either support or weaken outcomes connected to that space.
Doors, desks, cabinets, cash drawers, and beds are considered energy entry or resting points. When these are built or placed using inauspicious measurements, the flow of energy can feel blocked even if the space looks beautiful.
The Feng Shui ruler helps identify measurements that traditionally represent:
- Growth and success
- Stability and harmony
- Loss or obstruction
This is why Feng Shui rulers are still consulted during renovations, furniture buying, and even small home upgrades.
How Feng Shui Ruler Measurements Are Interpreted
The Feng Shui ruler is divided into segments, each representing a type of energy. These segments are categorized as favorable or unfavorable based on classical Feng Shui principles.
Positive measurements are often associated with:
- Smooth opportunities
- Financial steadiness
- Peaceful household energy
Unfavorable measurements are linked to:
- Delays
- Miscommunication
- Repeated obstacles
This calculator simplifies that interpretation by helping you quickly understand whether a measurement aligns with supportive energy or not, without needing physical rulers or manuals.

How to Use the Feng Shui Measurement Chart
- Measure the object (door, furniture, shelf, etc.) using a regular inch tape.
- Check which range it falls into using the chart above.
- If it lands in an inauspicious zone (like Disaster or Hardship), adjust slightly to the next auspicious inch (such as Luck or Prosperity).
- Use the “Prosperity,” “Nobility,” or “Strength” ranges for long-term success and harmony.
Signs Your Space May Have Measurement Imbalance
You may want to double-check measurements if you notice:
- Things breaking or needing frequent repair
- Restlessness or discomfort near certain furniture
- Difficulty maintaining focus at work
- A general feeling that a space “doesn’t feel right”
These signs do not mean something is wrong with you or your home. Often, subtle adjustments make a noticeable difference.
