1. What is Floor Space Ratio (FSR)?

Definition: FSR is a planning control that measures the intensity of development on a site by comparing the total floor area to the site area.

Purpose: It helps urban planners and developers regulate building density and ensure appropriate land use.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( FSR \) — Floor Space Ratio (unitless)
• \( Total\ Floor\ Area \) — Sum of all floor areas (square meters)
• \( Site\ Area \) — Total land area (square meters)

Explanation: The total floor area is divided by the site area to determine the development intensity ratio.

3. Importance of Floor Space Ratio

Details: FSR is crucial for urban planning, zoning regulations, and ensuring buildings are appropriately sized for their lots.

4. Using the Calculator

Tips: Enter the total floor area and site area in square meters. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical FSR value?
A: FSR values vary by location and zoning, typically ranging from 0.5 for low-density to 5.0+ for high-density urban areas.

Q2: Does FSR include underground areas?
A: This depends on local regulations - some jurisdictions exclude basements from FSR calculations.

Q3: How is FSR different from FAR?
A: FSR (Floor Space Ratio) and FAR (Floor Area Ratio) are essentially the same concept with different names in different regions.

Q4: Can FSR be greater than 1?
A: Yes, an FSR > 1 indicates multi-story development where total floor area exceeds the site area.

Q5: Where can I find the allowed FSR for my property?
A: Check your local zoning ordinances or planning department regulations.
