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

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 study room in Ahmedabad. 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 Ahmedabad's composite climate need clear glazing?

Ahmedabad 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.

These figures are advisory — drawn from IS 3792 (Composite 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 Ahmedabad's climate matters

Ahmedabad 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.
