Guides · Floor Plan Measurement
Matterport 3D tours automatically generate schematic floor plans: clean, accurate top-down views of each floor. These plans are highly accurate (LiDAR-based on compatible devices) but Matterport doesn't display total square footage. This guide shows how to extract it.
Matterport uses LiDAR scanning on the Pro camera and on iPhone 12 Pro and later models, producing plans typically accurate to within 1–2% of a physical measurement. Non-LiDAR phone scans are accurate to about 2–4%. The schematic floor plan derived from the 3D model is one of the most reliable residential floor plan sources available.
In your Matterport dashboard (my.matterport.com), open the 3D tour settings and select Export → Schematic Floor Plans. This downloads a ZIP containing JPG images per floor plus a PDF. If you're a buyer without dashboard access, open the Matterport tour in a browser, navigate to the floor plan view within the tour interface, and take a high-resolution screenshot at full browser zoom.
Upload the exported floor plan JPG or PDF to MeasureFloorPlan.com. The exported files are high resolution and trace cleanly. For multi-story homes, upload each floor separately. Matterport exports typically label each file by floor level.
Trace the exterior perimeter of the above-grade living space. Matterport plans show the full footprint including garage: exclude the garage from your GLA polygon. Furniture and fixtures may appear inside the floor plan; ignore them and trace the outer perimeter of the exterior walls. Matterport exports include labeled room dimensions. Use the longest for scale calibration.
After calibration each polygon shows its area. For a two-story home sum both floors. Matterport plans typically measure interior dimensions. For appraisal comparison to exterior GLA, note that wall thickness (typically 6–8" per exterior side) is not included in the Matterport interior measurement.

Start Measuring →Why doesn't Matterport show a square footage total?
Matterport's schematic floor plan is visual: it shows accurate room shapes and dimensions but does not aggregate them into a single GLA total. Calculating total square footage is left to the user with a measurement tool.
How accurate is a Matterport schematic floor plan?
Within 1 to 3 percent of field measurements. Accuracy depends on capture density (number of 3D scan points) and complexity of the layout. Tight spaces and curved walls have more variance than open rectangular rooms.
How do I get total GLA from a Matterport plan?
Export the schematic floor plan as PNG or PDF, upload it to a measurement tool, set scale from any labeled dimension on the plan, and trace the exterior perimeter. The result is ANSI-compliant GLA in about two minutes.
Can I measure each floor of a multi-story Matterport plan?
Yes. Matterport exports each floor as a separate page or section. Upload one floor at a time, trace the perimeter of each, set scale per floor, and add the floor totals together for total GLA.
Should I use Matterport's interior or exterior dimensions?
Matterport shows interior dimensions by default. For ANSI Z765 GLA you need exterior measurement. When tracing in the measurement tool, follow the outside wall line in the plan, not the interior wall surface.
