Floor Space Ratio (FSR) measures the total usable floor area compared to the overall plot or land area. A high ratio indicates dense usage—multiple floors or extensive coverage—while a low ratio suggests limited structures or large open zones. This ratio helps planners gauge development intensity, ensuring balanced layouts that align with aesthetic or policy objectives.

Key Points

• Calculation: Dividing gross floor space by the parcel area.
• Regulatory Control: Some jurisdictions cap FSRs to limit congestion or maintain uniformity.
• Impact on Layout: Higher FSR can allow more occupant units or compartments.
• Design Constraints: Exceeding norms may require special waivers or alternative compliance steps.

FSR clarifies how extensively an asset’s site is built up, guiding developers, lenders, or architects in visualizing scale, potential occupant capacities, and compliance with guidelines.
