Window to Door Ratio
Windows should outnumber doors in every dwelling — more light entry than passage
Local term: खिड़की-दरवाज़ा अनुपात — विंडो टू डोर रेशियो (Khiḍkī-Darvāzā Anupāt — Window-to-Door Ratio)
Modern Vastu recommends a minimum 2:1 window-to-door ratio. Building codes require every habitable room to have at least one window meeting minimum size requirements. Windowless rooms are restricted to storage and utility use. Ventilation and natural light are recognized as essential for health — aligning modern standards with traditional Vastu principles.
Source: Contemporary Vastu + National Building Code of India
Unique: Building codes independently mandate minimum windows — modern safety aligns with traditional Vastu.
The Rule in Modern Vastu
Ideal
all
At least 2:1 window-to-door ratio across the dwelling, per modern Vastu consensus integrating classical prescriptions with contemporary building practice — the architect must verify compliance before the Griha-pravesha ceremony.
Acceptable
all
Every habitable room has at least one window meeting code requirements.
Prohibited
all
More doors than windows creates a dwelling that is all passage and no light — Prana enters and exits without being retained or circulated. Rooms with doors but no windows are Andha Kosha (blind chambers) where energy stagnates. A house with excessive doors and few windows resembles a corridor rather than a habitation. The contemporary Vastu consensus synthesizing classical prescriptions reinforce this prohibition across all directions.
Sub-Rules
- Windows outnumber doors by at least 2:1 ratio▲ Moderate
- Every room has at least one window▲ Moderate
- Rooms with doors but no windows exist▼ Moderate
- More doors than windows in the dwelling▼ Moderate
Windows should outnumber doors in every dwelling — more light entry than passage creates a home that breathes freely and retains Prana. Rooms without windows are blind chambers where energy stagnates. The ideal ratio is at least 2:1 windows to doors.
Common Violations
More doors than windows in the dwelling
Traditional consequence: The dwelling becomes a passage rather than a habitation — Prana flows through without being retained. Occupants feel restless and unsettled, as the energy pattern favors transit over residence.
Rooms with doors but no windows
Traditional consequence: Andha Kosha (blind chambers) where stale Prana accumulates — associated with respiratory issues, lethargy, and negative mental states.

Hoysala Jali Kitiki — perforated stone screens as abundant window openings.
Kerala Nadumuttam courtyard — the largest single opening, supplementing room windows.
Haveli Jharokha density — highest natural window-to-door ratio in Indian architecture.
Bengali climate mandate — window abundance essential for ventilation in humid conditions.

HemadpanthiClassical Sources
“The Gavaksha (windows) of a dwelling shall exceed the Dwara (doors) in number — for the house that has more eyes than mouths sees more than it consumes, and the Prana that enters through Prakash (light) nourishes more deeply than the Prana that enters through Marga (passage).”
“A well-built dwelling has abundant Vatayana (windows) — more openings for light than for passage. The builder who makes many doors but few windows builds a sieve that catches nothing, while abundant windows make a dwelling that breathes with the rhythm of day and night.”
“The Sthapati shall plan Gavaksha in greater number than Dwara for each Bhumi (floor). Rooms without Gavaksha are Andha Kosha — blind enclosures — where Prana grows stale and disease takes root. Even the smallest chamber requires one opening to the sky.”
“Vishvakarma ordains that a Griha (house) shall have its Vatayana exceed its Dwara. The eye of a house is its window; the mouth is its door. A being with many eyes and few mouths is wise; a being with many mouths and few eyes is wasteful. So too the dwelling.”
“In the planning of openings, the Gavaksha count shall be the greater — for through windows enters the Tejas (light-fire) of Surya, and through windows enters the Prana of Vayu, and these two sustain the dwelling more than passage through doors.”
