Room Size and Proportions
The clearest decision guide: rooms under 300 sq ft (1BHK living rooms in Mumbai, studio apartments, spare rooms) → traditional 2-seater or 3-seater. Rooms 300–450 sq ft → 3-seater + accent chairs, or a compact L-shape. Rooms above 450 sq ft → sectional creates the most functional seating arrangement. Indian living rooms of 400–600 sq ft (common in 3BHK Mumbai apartments and most Delhi/Gurgaon apartments) are sectional territory — a solo 3-seater sofa looks under-scaled in a room this size.
