The oldest grid
Among the ways the classical Vastu tradition divides a dwelling, the nine-square is the most fundamental: a square cut into three rows and three columns. The eight outer squares belong to the eight directions; the ninth, in the middle, is the centre the tradition keeps open. Larger grids refine this one, but the nine-square already carries the essential logic — periphery for activity, centre for stillness.
Computed, not sketched
This tool builds the nine squares for your real orientation. Enter the facing degree and it assigns each square its direction, its element and its traditional role, adjusting for however your building is rotated. The calculator quotes the practice's source records with the result, so the classical lines behind each field appear exactly as recorded, beside the computation.
How to use this tool
Enter the facing degree, lay the resulting grid over your plan, and walk square by square: which room occupies it, and what the tradition expects of that field. Give special attention to the central square — the tradition asks that it stay light and unburdened — and to the corner fields, which carry the strongest characters.
FAQ
Q. How does this differ from the 45 Devtas grid? The nine-square is the broad frame; the 45 Devtas page descends into the finer seats within the full mandala.
Q. What belongs in the central square? As little as possible — openness, light, circulation. The Brahmasthan page treats this fully.
Q. Does a rotated building change the squares? The squares follow the compass, so a rotated building's rooms map differently — which is exactly what the tool computes.
The classical basis appears with each calculation result, quoted from the practice's source records.
