How our Vastu analysis and score work

From floor plan to Vastu reading: six steps

1. **Upload.** You provide an image of a floor plan.

2. **Boundary.** The outer outline is detected and you confirm or correct it.

3. **North.** You set North with a compass or map. This is the input with the biggest effect.

4. **Zones.** We compute the centre of the outline and divide it into 8, 16 or 32 zones from North.

5. **Rules.** Each room is matched to the classical suitability of the zone it occupies.

6. **Score and remedies.** Paid plans add a 0–100 score, room analysis and remedies.

How zones are assigned

• The centre is computed from the traced outer boundary of your plan.
• Zones are 22.5-degree sectors for the 16-zone grid, measured clockwise from North.
• Each room is measured by how much of its area falls in each zone, not by a single point.
• A room's main zone is the one that holds most of its area. Smaller overlaps are reported too.

How the Vastu score is calculated

For each room we take the share of its area in each zone and multiply it by the suitability of that zone for that room's use. Rooms are then combined using weights that reflect how much each placement matters in practice.

Where the rules come from

Our rules follow classical Vastu guidance as taught in the Mahavastu tradition and in standard texts. Texts commonly cited in the field include \[Brihat Samhita, Mayamata, Manasara, Samarangana Sutradhara, Vishvakarma Prakasha: expert to confirm which ones each rule cites\]. Every rule carries its source and a review date in the rules file, and changes are recorded in the changelog below.

What the analysis cannot do

• It cannot judge a site it has not seen. It reads the plan you provide.
• It cannot correct a wrong North or a plan that is far from scale.
• It does not replace structural, legal or engineering advice.
• It does not predict outcomes. Vastu is traditional guidance for layout.
• Irregular plots, large sites and expensive decisions deserve a consultation.

How the rules are reviewed

A Vastu consultant reviews every rule before it is used in the tool, the preview or a report. Rules are versioned. A rule changes only after review, and the date and reviewer are recorded.
