Common workflows
How appraisers use it on every report
GLA from CubiCasa or Matterport
Both produce accurate, to-scale floor plans but intentionally omit the area. Upload the export, set one wall length, done.
Finished basement GLA
Trace above-grade area with one polygon, below-grade with a second. PlanSnapper keeps the totals separate and ANSI-compliant.
Cross-check a field sketch
Run the tool on your CubiCasa or Matterport plan and compare against your sketch. Catch dimension errors before they hit the report.
Verify MLS size
Run the floor plan yourself before the report. Catches honest mistakes and not-so-honest ones before they become liability issues.
Remote or desktop review
Measure from the office when a field visit is not possible or not billable. Any to-scale floor plan in your inbox is enough.
Garage and porch exclusions
Add a second polygon to exclude attached garages, covered porches, or any non-GLA area. The math comes out right automatically.
How it works
Three steps from floor plan to GLA
Upload the floor plan
Export from CubiCasa, Matterport, or iGUIDE as PNG or PDF. Screenshot from the MLS. Photograph a printed plan. Any to-scale image works.
Set the scale with one known wall
Click two points on any wall you know the length of. A room dimension, a lot line, anything. PlanSnapper calibrates every other measurement from there.
Get ANSI-compliant GLA
Total GLA, perimeter, and individual wall lengths in feet and inches. Add a second polygon for basement or garage exclusions. Export the result.

Built by an appraiser. Used by professionals.
I built PlanSnapper because I was tired of printing floor plans and measuring them with a ruler. Now I verify GLA from my desk in minutes. It’s completely changed my appraisal workflow.
