What is the ideal window size for a north-west-facing study room in Bengaluru?

Vastu and temperate climate together suggest a window approximately 4 feet wide with a sill height of 2.5 feet on a north-west face for a study room in Bengaluru. Type: Sliding 2T. Glazing: clear.

Is North-West an auspicious direction for a study room per Vastu?

Yes — North-West is the ideal Vastu direction for a study room. Vayu (Vayu (Air)) governs this direction, and the room aligns naturally with that energy.

Why does Bengaluru's temperate climate need clear glazing?

Bengaluru sits in the Temperate climate zone (Mild year-round. The most forgiving zone — and the most often over-engineered.). For temperate climates, clear glazing balances solar gain, heat retention, and visibility — A Bangalore wall does not need to be a Jaipur wall. Most builders copy the same envelope anyway and the home pays the bill.

These figures are advisory — drawn from IS 3792 (Temperate zone) and Vastu Shastra teaching tradition. An architect should adapt them to your plot's exact bearing, plinth height and facade design.

Why this direction for a study room?

A study window should put light over the desk shoulder (not into the eyes), support video-call ambient light, and crucially provide the option to look up and rest the eyes on a distant view — no view = eye-strain.

Vastu's ideal placement for a study room is W, NW — North-West sits in this band.

Why Bengaluru's climate matters

Bengaluru is in the Temperate climate zone (Cwb, Cfb per the Köppen scale; Temperate per NBC 2016). Summer temperatures: 25-35°C, winters: 12-22°C. Rainfall: 500-1500 mm/year. Humidity: 40-75%.

A Bangalore wall does not need to be a Jaipur wall. Most builders copy the same envelope anyway and the home pays the bill.

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 mild year-round temperatures with comfortable airflow.
