Step-by-step guides on measuring floor plans, calculating GLA, and getting accurate square footage from any image or PDF.
Setting scale is the single most important step. Click two points on any wall you know the length of. Everything else calibrates from that one reference.
Trace each floor as a separate polygon and sum them for total GLA. How to handle staircases, voids, and partial upper floors.
Open plans have no interior walls to define areas. Trace the outer perimeter of the entire above-grade finished space as a single polygon.
Trace the full L as one polygon or split into two rectangles. The tracing tool handles irregular shapes natively, no manual math needed.
Bay windows, angled walls, curved walls, and bump-outs all handled. Tips for tracing complex shapes accurately.
Condos typically use interior wall-to-wall measurement rather than exterior. How to trace interior perimeter and which convention to use.
Multiple floors, shared party walls. Trace each floor separately. For shared walls, measure to the centerline. Stack floor totals for GLA.
How appraisers use the tool to verify or recalculate GLA from scanned sketches and digital floor plans. Faster than re-drawing in sketch software.
Catch square footage discrepancies before listing. How to verify MLS square footage from the floor plan before the appraisal finds a problem.
County records, Zillow, and MLS numbers often disagree. How to get the floor plan and check the math before making an offer.
Accurate square footage affects per-square-foot lease pricing. How to measure rentable area from a floor plan and what to count.
Verify square footage on acquisition targets from the floor plan before making an offer. Fast workflow for running multiple properties.
