When asking about feng shui for a home, many people want to know the facing direction of the front door first. But “facing direction” is not a permanently correct answer produced by holding a phone at the entrance: different feng shui schools may start from the building, the unit’s main entrance, the door used most often, or the direction outward from the door. A more careful approach is to record the purpose of the measurement, the entrance, and the tool, so that any later interpretation uses the same information. Direction is one part of a traditional observation; it is not evidence that guarantees family health, wealth, or relationship outcomes.
First distinguish how “sitting” and “facing” are being used
In everyday language, “facing south” usually describes the direction a person faces. In traditional terminology, sitting and facing often describe a pair of opposite directions for a building’s rear and principal orientation, but definitions and reference points vary. Write down whether you are measuring while standing inside the front door and facing out, or standing outside and facing in; do not keep only one degree reading. If a home has two entrances, state which one is used for ordinary access and which one is for back-of-house or emergency use.
- Record the unit’s floor, principal entrance, balcony, and back-door positions.
- Draw your standing position and the arrow showing which way your body faces on a simple plan.
- Note the date, time, tool, and whether large metal objects were nearby.
Draw the entrances and reference points before measuring
Use paper to draw a floor plan that does not need engineering precision, marking door frames, the lift lobby, metal gates, windows, fixed cabinets, and large appliances. In a high-rise building, the area outside the door may contain steel doors, lifts, railings, or electrical equipment. If you read a direction beside these objects, treat it as an observation affected by the environment, not as the home’s only facing direction. You can also mark whether the door opens toward a corridor, platform, or outdoor space so that different standing positions can be compared.
How to hold a compass for readings you can repeat
With a physical compass, move away from phones, earphones, keys, magnetic accessories, metal table legs, and large appliances, and keep the compass level. Stand on the reference line you have chosen at the entrance and do not rotate your body while reading. Place the compass along the same line of facing, wait for the needle to settle, and record one reading. Then move a few steps and repeat. If three readings are spread noticeably apart, record the spread and the nearby interference instead of choosing the angle that best matches what you hoped to see.
The Hong Kong Observatory’s information on geomagnetism explains that magnetic north indicated by a compass differs from geographic true north. Mountains, minerals, trains, aircraft, and cables may also create local anomalies. This explains why readings can vary slightly at different points near the same entrance; it does not mean that one number found online can provide a precise correction for every home.
A phone compass is useful for comparison, not for trusting one display
A phone compass is convenient, but it can be affected by the phone case, magnetic mount, nearby appliances, and the device’s calibration. Remove magnetic accessories before measuring and complete the calibration suggested by the phone. Hold it flat, keep it on the same facing line as the physical compass, and record the reading. Measure once inside the door, once outside, and once a few steps away from metal objects, then compare the change. If the phone and physical compass disagree, first check position, posture, and interference rather than immediately declaring one of them the true direction.
Put the direction back on the floor plan instead of interpreting it alone
After measuring, place the arrow on the floor plan and add the bed, desk, kitchen, bathroom, windows, and main movement paths. In traditional feng shui, the entrance direction is only one of many observations. Actual living also depends on light, ventilation, noise, privacy, storage, and how family members use the space. If the direction has not been confirmed, label it “approximately this direction, pending review” and begin with non-structural adjustments such as reorganising clutter or putting frequently used items where they are easier to reach.
Keep three records so a later discussion can respond to the evidence
Put the three readings, photographs, standing positions, and tools on one page rather than saving only a screenshot of one phone-compass display. If you measure again later, use the same record format so you can tell whether a difference comes from position, time, tool, or the definition of the entrance. In a rental home, office, or shop, also confirm what may be measured and changed. Do not demolish walls, drill holes, move fixed equipment, or alter common facilities because of a direction interpretation.
Record a building entrance separately from the home entrance
The public entrance of a building, a resident’s metal gate, and the unit’s front door may not be the same reference point in a traditional discussion. Photograph and measure each entrance separately, stating which door is used most often. If there is a balcony door, back door, or studio entrance, include it in a comparison only if it genuinely carries the main access function; do not automatically treat a wider door as the facing direction. This record lets the family agree first on what “main entrance” means.
The same phone may show different readings in a lift lobby, beside a metal gate, and near an interior wooden door; that difference is itself information. Make a table of standing position, reading, nearby objects, and repeat results before deciding whether to ask someone familiar with the relevant school to interpret it. If measuring would require standing in a roadway, by stairs, or in a narrow common area, move to a safe position or use the floor plan only. Do not take a risk to pursue one angle.

Keeping measurement limits visible is more reliable than pursuing a seemingly precise lucky-or-unlucky label.
