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

Vastu and temperate climate together suggest a window approximately 3 feet wide with a sill height of 2.5 feet on a west face for a pooja room in Bengaluru. Type: Sliding 2T. Glazing: clear.

Is West an auspicious direction for a pooja room per Vastu?

West is an acceptable secondary placement for a pooja room. The traditional ideal is NE, but the room remains usable in West with the standard window choices.

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.

Why this direction for a pooja room?

A pooja room window's job is to bring morning light to the deity at dawn — small, high-sill, and on the NE wall ideally. The window should never face directly at the deity but rather light the side wall, creating soft fill light during morning aarti.

Vastu's ideal placement for a pooja room is NE. West is an acceptable secondary 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 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.
