Square Footage Calculator

GLA is the total area of finished, above-grade residential space. It is audited by measuring the outside dimensions of the structure, excluding unfinished areas like basements, garages, and attics unless they meet specific HVAC and occupancy codes.

It is the global benchmark for measuring office buildings. It provides a uniform methodology for calculating rentable area, ensuring parity between tenants and landlords across international jurisdictions.

The L-Shape audit utilizes a 'Composite Decomposition' algorithm. It breaks the polygon into two prime rectangles, calculates their individual areas, and reconciles them into a single total magnitude to prevent overlap errors.

Yes. The geometric logic is scale-invariant. Whether you are auditing a 100 sq ft room or a 50,000 sq ft industrial lot, the precision remains constant at 10 decimal places.

Institutional real estate standards (HUD and Appraiser guidelines) require exterior measurements as they represent the physical footprint and structural integrity of the asset.

In professional auditing, wall thickness is included in the GLA (Gross Living Area) but excluded from NIA (Net Internal Area). This calculator provides the raw magnitude; users should subtract interior partitions for NIA audits.

To audit paintable area, calculate the wall perimeter (2 x Width + 2 x Length) and multiply by height. Subtract 15-20 sq ft for standard door/window apertures for high-fidelity estimations.

We utilize the π (Pi) constant to 15 decimal places ($3.141592653589793$). This ensures that even large-scale circular structures (like grain silos or arenas) are audited with near-zero mathematical drift.

In construction and roofing, one 'Square' is exactly 100 square feet. This tool helps audit how many Squares are required for surface coverage based on flat-plane dimensions.

NRA excludes vertical penetrations like elevator shafts and stairwells. Our S-Class logic provides the total footprint; for commercial NRA, apply the relevant BOMA 'Load Factor'.

We use the exact NIST factor: 1 Square Foot = 0.09290304 Square Meters. This ensures that international real estate contracts remain in perfect dimensional synchronization.

Yes. Square footage is the primary variable for BTU calculation. An accurate area audit prevents over-scaling or under-scaling of climate control systems.

The engine uses the Classic Euclidean formula ($rac{1}{2} imes Base imes Height$). For non-right triangles, ensure the height is measured perpendicular to the base for institutional accuracy.

It is the ratio of NIA to GLA. Professionals target a ratio of 85-90%. Using this tool to audit actual room dimensions vs the total footprint helps identify floor plan inefficiencies.

This branch focuses on 2D area. For volume audits (HVAC/Concrete), simply multiply the resulting Square Footage by the vertical height (Z-axis).
