How to read the 16 Vastu zones
Learn the 16 compass sectors, their 22.5° spacing and the plan, north reference and property boundary needed before a Vastu zone review.

Read the circle as a compass
A 16-zone circle divides a full turn of 360° into sixteen equal sectors. Each sector is 22.5° wide. In the explorer on this website, North is centred on 0° at the top and the labels progress clockwise. East is centred on 90°, South on 180° and West on 270°. The intermediate labels give more detail than an eight-direction compass.
Starting at North, the sequence is N, NNE, NE, ENE, E, ESE, SE, SSE, S, SSW, SW, WSW, W, WNW, NW and NNW. Sector centres increase by 22.5° each time. North spans 348.75° through 0° to 11.25°; in this explorer a shared boundary belongs to the sector that starts at that angle. This keeps a boundary point from appearing in two sectors at once.
Establish the plan and north reference
A useful plan shows the property outline, dimensions, entrance and the rooms being reviewed. Mark north clearly and explain how it was established. Ask which north reference and measurement method the practitioner uses; do not silently mix a plan’s north arrow with an unverified phone reading. If your existing plan is only a sketch, identify the uncertain dimensions so they can be checked before detailed mapping.
The circle does not establish north from your device. Rotating a decorative diagram or selecting a direction on screen also does not locate a room in your home. Those actions demonstrate a compass relationship; the property measurements still have to come from the actual plan.
Confirm the centre and boundary before overlaying
A zone overlay needs an agreed centre and an agreed boundary. For a simple rectangle, its geometric centre is where the midlines meet. Apartments with cut-outs, L-shaped outlines, shared areas, terraces or extensions need careful review of what is included. Do not choose the centre of one room and assume it is the centre of the whole property. Bring questions about uncertain boundaries to the practitioner.
Once the boundary, centre and north reference are established, an overlay can show which sectors different parts of a room cross. A room may occupy more than one zone. That is why a direction name alone, or an entrance-facing label, cannot describe the complete layout.
Use the explorer for learning, then ask specific questions
The website circle is an educational illustration of the sixteen directions. It is not a sensor, a personalised house diagnosis or an instruction to move fixed construction. Some Vastu practitioners use a 16-zone mapping method; its interpretations should be discussed as traditional guidance rather than guaranteed effects. Ask how the plan was mapped, which assumptions were made and which proposed changes are practical for your situation.

Bring your measured plan and questions to a consultation before acting on room-specific recommendations.
