What is the ideal window size for a north-west-facing master bedroom in Chandigarh?

Vastu and composite climate together suggest a window approximately 4 feet wide with a sill height of 2.5 feet on a north-west face for a master bedroom in Chandigarh. Type: Sliding 2T. Glazing: clear.

Is North-West an auspicious direction for a master bedroom per Vastu?

North-West is an acceptable secondary placement for a master bedroom. The traditional ideal is SW, but the room remains usable in North-West with the standard window choices.

Why does Chandigarh's composite climate need clear glazing?

Chandigarh sits in the Composite climate zone (Hot summers, cold winters, monsoon — the climate where classical Vastu was calibrated.). For composite climates, clear glazing balances solar gain, heat retention, and visibility — Operable windows matter more than fixed ones. The same opening that bleeds heat in January welcomes it back in July.

Why this direction for a master bedroom?

A master bedroom needs cross-ventilation for sleep quality, controlled morning light (so the room doesn't double as a sunrise alarm), and visual privacy from neighbouring plots. Two windows on perpendicular walls is ideal — one bigger for light, one smaller for airflow.

Vastu's ideal placement for a master bedroom is SW. North-West is an acceptable secondary band.

Why Chandigarh's climate matters

Chandigarh is in the Composite climate zone (Cwa, Cfa per the Köppen scale; Composite per NBC 2016). Summer temperatures: 35-48°C, winters: 2-15°C. Rainfall: 500-1200 mm/year. Humidity: 20-90% (seasonal).

Operable windows matter more than fixed ones. The same opening that bleeds heat in January welcomes it back in July.

For a north-west face in this climate, the recommendation is a sliding 2t window with clear glazing and a sill at 2.5' — calibrated for hot summers, cold winters, and seasonal monsoon.

Common mistakes

Placing the largest window on the east wall — early sun disturbs sleep cycles
Bed-head against the same wall as the window — drafts and noise reach the sleeper directly
Mirrors directly opposite the bed reflecting the sleeping body
