How to Use Avenir Developments' FAR Calculator
Enter plot area and coverage, optionally setbacks and heights; the calculator computes FAR, floor-plate and compliant floor counts instantly online.
Input the plot area in square feet (or marla/kanal/square metres), choose a coverage percentage, and optionally add setbacks and maximum building height to estimate a realistic floor‑plate and potential floors. The calculator then derives FAR as Total Floor Area ÷ Plot Area. If you know the permitted FAR from your authority, enter it to understand maximum buildable area; otherwise, use coverage plus geometry to approximate capacity. Results are presented in clean, exportable blocks—ready to share on WhatsApp or save as a PDF—so decisions move forward quickly and transparently.
Input Permissible FAR
Enter the Floor Area Ratio allowed for your specific zone or locality, which can usually be obtained from local development authority regulations.
Enter Plot Area
Input the total area of your land parcel in the specified units (e.g., square feet, square yards).
CLICK 'CALCULATE'
Our tool will instantly compute the maximum permissible gross floor area for your property.
FAR (Floor Area Ratio) / FSI Calculator
Compute Allowed GFA (Gross Floor Area) from Plot Size × Permitted FAR. Optionally add Desired GFA to check compliance. (Basements excluded from FAR.)
Plot, Units & Permitted FAR
Also called FSI (Floor Space Index), this FAR calculator helps architects, developers, planners and investors evaluate zoning, density and buildability in Pakistan (CDA, LDA, SBCA, RDA) and worldwide.

What is a Floor Area Ratio Calculator?
Understand Floor Area Ratio, also called Floor Space Index, used by zoning authorities to control density and building bulk on
Floor Area Ratio (FAR)—also known internationally as Floor Space Index (FSI)—is a planning control that compares a building’s total floor area with the size of its plot. In simple terms, FAR = Total Built Floor Area ÷ Plot Area. Municipal authorities use FAR to manage density, sunlight access, infrastructure load and neighborhood character. In Pakistan, agencies such as CDA, LDA, SBCA and RDA specify FAR limits by zone, road width and land‑use. Globally, FAR or FSI works similarly across most cities. A higher FAR allows more floor area on the same plot; a lower FAR keeps buildings smaller and streets less congested.

How Important is FAR in Real Estate Development?
Discover why understanding FAR is vital for property valuation, project feasibility, and regulatory adherence in Pakistan’s real estate market.
FAR is immensely important for various stakeholders in the real estate sector. For developers, it directly impacts the maximum buildable area, influencing project scale, cost, and potential revenue. For investors, it’s a key factor in assessing a property’s development potential and long-term value. Moreover, adhering to FAR regulations is crucial to avoid legal complications and ensure smooth project execution.
Maximizing Development: Helps developers understand the maximum permissible construction.
Property Valuation: Directly influences the commercial value and potential of a land parcel.
Legal Compliance: Essential for obtaining building permits and avoiding penalties.

Who is the FAR Calculator for?
Designed for architects, planners, developers, investors and students needing quick FAR checks for Pakistan and worldwide zoning contexts and approvals
This tool is for everyone who needs fast, reliable feasibility checks: architects preparing concept massing, planners validating zoning envelopes, developers and investors evaluating site yield, real‑estate agents comparing plots, and students learning how planning metrics shape built form. It is tailored for Pakistan’s context—CDA (Islamabad), LDA (Lahore), SBCA (Karachi), RDA (Rawalpindi)—while using global FSI/FAR vocabulary so international users feel at home. The interface is intentionally simple and mobile‑friendly, making it easy to sanity‑check project potential during site visits or client meetings.
