Compass vs BTB Bagua: Which Map Should You Use?

Use the alignment rule of the method you are following. A compass-based Bagua follows measured directions. The entrance-aligned BTB Bagua uses the entrance side as its reference. Switching that reference changes where the labels fall, even though your home has not changed.

If one guide says “southeast” and another says “the far-left corner from the entrance,” first check which method each guide teaches. Do not combine those instructions into one map.

The International Feng Shui Guild glossary distinguishes direction-based Compass mapping from entry-relative BTB terminology. Here, “Compass” refers to a simplified directional teaching example. It does not represent every classical method or replace an Eight Mansions or Flying Star assessment.

For the broader introduction and area meanings, read our Bagua map guide. This article focuses on choosing between alignment rules and resolving conflicting instructions.

Imagine a square room plan with north at the top. Its formal entrance is on the west wall, toward the southwest corner. A desk sits in the northeast corner, and an armchair sits in the southeast corner.

One illustrative layout, two alignment rules. The nine-cell grids are teaching aids, and the life-area names are traditional symbolic associations. This is not a measured client assessment.

In the left-hand example, the labels follow the compass directions. In the right-hand example, the BTB entrance row runs along the west side—the left column of this north-up picture. The house itself has not rotated.

Stand at the western entrance and look east into the room: your left is north, and the far side is east. This is the viewing position used to interpret the BTB example.

The doorway is deliberately off-center. It shows why “align the entrance row” does not mean “move the Career square to wherever the door happens to be.” In this BTB arrangement, the doorway falls in Helpful People, one of the three entrance-side areas.

These differences do not require you to move the desk or armchair. They show what happens when you change the map's reference. Decide which framework you are using before interpreting its labels.

The example uses a simple square footprint. Directional assessments may use sectors radiating from a center rather than equal squares. Do not force this diagram onto a rotated, irregular or multi-level home without addressing its boundaries and the method's requirements.

Before changing your room, check the instructions that produced each map.

For the garage-door question, Mindful Design School's BTB explanation uses the formal front door even when occupants usually enter through a garage. That is the specific BTB convention used here; it should not be presented as a rule shared by every Feng Shui tradition.

A doorway's location on a drawing, the direction someone faces while standing in it, and the building-facing direction used in a particular assessment are also different pieces of information. Do not assume one automatically supplies the others.

The compass and plan are illustrative. Use the instructions below to check your own reference.

Step 1: Name the method

Write down the name used by the teacher, book or guide you are following. If the instructions never identify their alignment rule, clarify that before applying them. “Feng Shui says” alone is not enough to identify a method.

Step 2: Fix the reference and boundary

For a compass-based exercise, establish and record your directional reference. A map and a phone compass may use different north settings; do not silently switch between them. If readings remain inconsistent, pause and verify them.

For the BTB example in this article, identify the formal entrance side. Record whether you are mapping the whole home or one room. If the boundary or entrance is ambiguous, seek guidance within the method you chose rather than selecting whichever orientation gives a preferred label.

Step 3: Keep one rule set for the exercise

You can compare two separately labeled maps, as we have done here. But use one set of alignment rules when completing a particular exercise. Do not position the map using the entrance and then interpret its cells as fixed compass directions.

If you want to continue with our practical exercises, the Bagua Map Starter Guide uses the compass-based approach. It includes notes, room observations and an action plan; it does not switch into a BTB workbook.

Whatever framework you choose, keep the practical review concrete: can the door open fully, can people move comfortably, does the desk avoid troublesome glare, and does the seating suit its use? A symbolic label should not override those needs. Changing a label is not evidence that a room will produce a particular financial, health or relationship outcome.

Does the front door have to be in the Career area?

No. In the BTB grid described here, the entrance-side row contains Knowledge, Career and Helpful People. An off-center door can fall in either side area. In a compass-based map, the doorway does not redefine north or move the directional labels.

What if I use the garage door every day?

Under the Mindful Design BTB convention cited above, use the formal front door. Daily use of another entrance does not, by itself, change that reference. If you follow a different teacher or school, confirm its rule before drawing the map.

Can I combine Compass and BTB Bagua?

For this introductory exercise, keep the alignment systems separate. Comparing them can explain conflicting advice; combining one system's positioning rule with the other's labels makes the result difficult to interpret consistently.

Is a north-up map different from a south-up map?

A different display orientation does not necessarily mean a different method. Compare the direction labels first. Rotating a labeled compass diagram preserves its relationships; mirroring it reverses them. A BTB diagram is identified by its entrance alignment, not merely by which way it appears on the page.

Is Compass Bagua the same as a Flying Star chart?

No. This article compares a simple directional reference with an entrance-aligned grid. Flying Star work involves additional calculations and time-related information. These diagrams are not a residential Flying Star chart and should not be used as one.

Start with one clearly named method and a reliable reference. Then use your map to guide observations, while judging any proposed room change by how well it supports everyday life.
