What is the ideal window size for a north-east-facing dining room in Delhi?

Vastu and composite climate together suggest a window approximately 5 feet wide with a sill height of 2.5 feet on a north-east face for a dining room in Delhi. Type: Sliding 2T. Glazing: clear.

Is North-East an auspicious direction for a dining room per Vastu?

North-East is an acceptable secondary placement for a dining room. The traditional ideal is W, but the room remains usable in North-East with the standard window choices.

Why does Delhi's composite climate need clear glazing?

Delhi 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 dining room?

Dining-room windows want soft, even light during meal times (especially evening) and connection to the kitchen-side air for serving comfort. A west-facing window with light afternoon shade is the classic choice — it catches the soft golden hour during dinner.

Vastu's ideal placement for a dining room is W. North-East is an acceptable secondary band.

Why Delhi's climate matters

Delhi 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-east 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

Mirror directly opposite the dining table reflecting food / diners
Sliding doors instead of windows — diners feel exposed during meals
Diners face the glare of an unshaded west window during evening meals
