What is the ideal window size for a south-facing kitchen in Bengaluru?

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

Is South an auspicious direction for a kitchen per Vastu?

South is an acceptable secondary placement for a kitchen. The traditional ideal is SE, but the room remains usable in South 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 kitchen?

Kitchen windows must extract cooking smoke and steam (so an exhaust-fan window over the cooktop is non-negotiable), let in morning light when the kitchen sees dawn use, and ideally allow a glance at the entry / dining area for family interaction while cooking.

Discipline, storage, mass. The heaviest face — anchor with weight, not lightness.

Vastu's ideal placement for a kitchen is SE. South 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 south 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.

Common mistakes

Sink directly below the window — splashing wets the wall and corrodes the sill
No exhaust window over the cooktop — steam damages the ceiling
South-facing kitchen window with no shading — afternoon heat compounds the cooking heat
