You can find your house's facing direction using a smartphone compass app corrected for magnetic declination, a satellite map with a compass overlay, or the sun's rising and setting path, all without buying a compass. Facing direction is the compass bearing of the wall that holds your main entrance, and it is the starting point for nearly every feng shui reading of a property.
Most people only think about this the day they actually need it. You may be standing on the porch with your phone out, watching a compass app twitch between numbers, or trying to remember whether the road runs north to south past the house so you can work out which way the driveway faces. It feels like it should be simple. It often is not, mostly because nobody explains what you are actually supposed to be measuring in the first place.
What "Facing Direction" Actually Means
Facing direction sounds like it should be obvious, the direction your house points. In practice it means something more specific: the compass bearing of the exterior wall that contains the main entrance, measured standing at that wall and facing outward, not from inside the house looking out.
This distinction matters because a house is not always oriented the way its street address suggests, and it is not always the direction most of its windows happen to face. A house can have a wall of large windows looking out over a backyard to the west, while the official entrance, and therefore the facing direction, points east toward the street. Feng shui traditionally separates these two sides of a home into the facing side and the sitting side, which is the wall directly opposite, usually where the main body of the house extends. Mixing these two up is one of the most common mistakes people make when trying this on their own, and it can change the entire reading that follows.
A modern way to picture it is to think about how a stage is oriented, not by where most of the furniture on it happens to sit, but by which direction the audience faces the performers from. The entrance is the audience side. That is the direction that counts.
Method One, Best Option: A Smartphone Compass App Corrected for Declination
Cost: free. Renter-friendly: yes, this requires nothing more than standing outside for a few minutes.
A compass app is usually the fastest and most accurate tool most people already carry, provided one easy step is not skipped: correcting for magnetic declination.
A phone compass reads magnetic north, the direction a needle actually points, which is not the same as true north, the direction used on maps and in most facing calculations. The gap between the two, called declination, can be close to nothing in some regions and can run past ten or fifteen degrees in others. Skipping this correction is the single most common reason people misjudge their facing direction by an entire directional category.
The steps:
- Search your address along with "magnetic declination," or use a free declination lookup tool, to find the correction figure for your exact location.
- Stand at the exterior of the main entrance, facing away from the house, with the entrance wall directly at your back.
- Open a compass app and read the bearing in degrees. Hold the phone flat and away from metal doorframes, mailboxes, or parked cars, since any of these can pull a reading off by several degrees.
- Add or subtract the declination figure, depending on whether it is listed as east or west for your area, to convert the magnetic reading into a true bearing.
That corrected number, somewhere between zero and 360 degrees, is your true facing direction.
Method Two, Next Best Option: Satellite Maps With a Compass Overlay
Cost: free. Renter-friendly: yes.
A satellite map already displays true north at the top of the frame, which means it sidesteps the declination problem entirely.
Open a mapping app in satellite view, center it on the house, and rotate the view until north points straight up, most apps reset to this orientation with a single tap on the compass icon. From there, trace an imaginary line straight out from the entrance wall, perpendicular to that wall, and estimate the angle that line makes against true north using the map's compass rose or a protractor held against the screen.
This method tends to be slightly less precise than a corrected phone reading, usually within five to ten degrees, but it has one real advantage: it shows the entrance wall's actual angle relative to the street, which a handheld reading taken standing on the ground cannot always show as clearly, especially on a house set at an angle to its lot rather than square to the road.
Method Three, Backup Option: The Sun Method
Cost: free. Renter-friendly: yes.
This is the oldest method there is, and it needs nothing but a clear day and a few minutes of patience. It works because the sun rises due east and sets due west only on two days each year, the spring and fall equinoxes, but its general east-to-west arc still gives a usable reference point on most other days.
Stand at the entrance around solar noon, the point when the sun sits at its highest for the day, roughly halfway between sunrise and sunset by the clock rather than exactly at 12 o'clock. At that moment the sun sits close to true south in the northern hemisphere. Note which direction that is relative to your entrance wall, and you have a rough directional reference without any device at all.
This is the least precise of the three methods, best used as a sanity check against a compass app reading rather than as a sole source. If the sun method and the compass app disagree by more than fifteen or twenty degrees, something went wrong with one of them, most often a missed declination correction or a compass reading taken too close to a metal object.
Common Mistakes That Throw Off the Reading
Getting the facing direction wrong by a wide margin is a moderate importance mistake, since it can place a house in the wrong directional category entirely, which changes the interpretation that follows from it.
- Reading the compass from inside the house rather than standing outside at the entrance wall.
- Confusing the facing wall with whichever wall has the most windows or the best view.
- Forgetting the magnetic declination correction, especially in regions where it runs into double digits.
- Taking a reading near a parked car, a steel door frame, a metal fence post, or while wearing a metal watch or belt buckle.
- Using a side or garage door because it is more convenient to reach, on a house where the true main entrance is elsewhere.
A Worked Example
Consider a house on Willow Creek Drive, a street that runs from the northeast down to the southwest. The lot is a standard 60 foot wide suburban parcel, and the house sits back 22 feet from the sidewalk, with its main entrance centered on the street-facing wall, a wall that measures roughly 34 feet across.
Standing at that entrance and facing away from the house, a phone compass reads 172 degrees magnetic. For this example, assume a magnetic declination of 8 degrees east, meaning magnetic north sits 8 degrees to the east of true north in this location. To convert the magnetic reading into a true bearing, add the declination: 172 plus 8 equals 180 degrees.
A true bearing of 180 degrees is due south. That places this house firmly in the south-facing category, not the southwest category it might have been mistaken for without correcting the reading. Here, the 8 degree adjustment was enough to move the result from what looked like a southwest lean to a clean south reading, and that distinction matters, because the guidance attached to a south-facing home is different from the guidance attached to a southwest-facing one.
How Important Is Getting This Exactly Right?
Knowing a house's true facing direction is important and permanent. The direction itself does not change. A house that faces south today faced south the day it was built and will still face south long after anyone reading this has moved on. What can go wrong is not the property, it is the measurement.
A wrong reading is not a permanent problem at all. It is easily fixable, usually in under ten minutes, by cross checking two of the three methods above against each other. This is not something that should factor into a decision to buy or not buy a house. It is closer to a preparation step, similar to measuring a room before ordering furniture, than a defect to weigh against the purchase.
Where precision matters more is at the edges. A reading of 178 degrees and a reading of 202 degrees can fall into different directional categories depending on the system used, so a house sitting close to a boundary line between two directions is worth double checking with more than one method before drawing conclusions from it.
What Not to Worry About
A few degrees of difference between methods is normal and rarely changes anything. If a phone compass reads 184 degrees and a satellite map estimate lands at 179 degrees, both are describing the same south-facing house, and there is no need to keep re-measuring until the numbers match exactly.
It is also common for a house to sit at a slight angle to the street rather than perfectly square to it. This does not mean the facing direction is unclear, or that something is wrong with the property. It simply means the entrance wall's actual angle should be read directly, rather than assumed from the street's general orientation alone.
The Bigger Picture
A facing direction reading is a starting point, not a conclusion. Once it is known, it should be considered alongside the road in front of the house, what sits behind and beside it, the slope of the lot, and who actually lives there, since the same direction can suit one household well and work against another. A single degree reading, taken on its own, only tells part of the story.

Frequently asked questions
Does the direction the windows face count as the facing direction?
No. Facing direction is determined by the wall that holds the main entrance, not by which wall has the most windows or the best view. A house can have large windows looking one direction and still have its facing direction assigned to an entirely different wall.
What if my house has two entrances that get roughly equal use?
The main entrance is usually the one built into the house's original design as the primary entry, often the one addressed on the street, even if a side door or garage door sees more daily use. When it is genuinely unclear, the entrance most aligned with the street or the driveway is the more common choice.
Do I need to correct for magnetic declination if I only use a satellite map?
No. Satellite and standard map views are already oriented to true north, so the declination correction only applies when reading a magnetic compass or a phone compass app directly.
How much can declination actually change my reading?
It depends entirely on location. Some areas have a declination close to zero, while others run past ten or fifteen degrees. A quick search for your address along with "magnetic declination" will return the correct figure, and skipping it is one of the more common reasons a reading lands in the wrong category.
Can a house face a direction that seems to contradict its street address?
Yes. A house numbered on one street can still have its main entrance, and therefore its facing direction, oriented toward a side street or a corner of the lot rather than straight at the addressed street, especially on corner lots or angled lots.
Is it worth paying a professional to confirm the direction?
For most houses, a careful reading using two of the three methods above is accurate enough. A professional reading becomes more useful when a house sits close to a boundary between two directional categories, or when the reading is going to inform a larger decision about the property.
