About this calculator
The Room Size Calculator recommends ideal dimensions for every room in an Indian home — living, master bedroom, kids' room, kitchen, bathrooms, dining — based on intended furniture, circulation and Vastu. Use it to validate a builder's layout, plan a renovation or decide which apartment to buy.
Indian apartment carpet areas are tight: a 2 BHK at 800–1100 sqft carpet has very little room to waste on poor proportions. The calculator tells you whether 12×14 feet is enough for the bed + wardrobe + workspace you have in mind — before you commit.

How the calculation works
Master bedroom: queen bed (5×6.5 ft) + 8 ft wardrobe + 3 ft circulation each side = 12 ft wide × 14 ft long minimum. With king bed (6×6.5 ft) + walk-in closet aim for 14×16. Kids' room: 9×11 sufficient with single bed; 11×13 for queen + study + wardrobe combo.
Why this estimate is more accurate
Apartment buyers see "12×14 master bedroom" in builder brochures with no sense of whether that's adequate. The calculator tells you exactly what fits — and what doesn't — so you don't buy a 3 BHK and then realise the master bedroom only takes a queen bed.

What affects the final cost
- Bed size choice — queen (5×6.5 ft) vs king (6×6.5 ft) drives 1 ft of room width.
- Wardrobe depth — 24" deep is sliding standard; 22" deep hinged saves 2" of floor.
- Bathroom door swing — outward swing saves 6 sqft of bathroom floor.
- Furniture circulation — 3 ft minimum between bed and wall; 4 ft preferred.
- Dining seat count — 4-seater needs 10×11; 6-seater 11×13; 8-seater 13×16.
- L-shape vs rectangular kitchen — L-shape works in 8×10; parallel needs 8×12.
