The number the listing agent
left off the floor plan
When listing agents share floor plans, the square footage is almost never included. That is not an oversight.

What appraisers see every day
The listing says 2,200 sq ft.
The floor plan says something different.
Square footage on a listing comes from the tax record, which comes from a permit estimate, a builder's spec sheet, or an appraisal done years ago. Nobody remeasures it when the house sells.
The listing agent gets a floor plan from the seller. They share it with you. But the square footage is conspicuously absent. Because if they included it and you measured it, the gap would be obvious.
As a buyer, you are negotiating price per square foot. A 200 sq ft discrepancy at $300/sq ft is $60,000. That money does not come back at closing.
What users say
Built by an appraiser. Used by professionals.
I built MeasureFloorPlan 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.

From raw floor plan to measured GLA
Upload any floor plan and get every perimeter measurement with total size.
How it works
Measure it yourself. Takes 2 minutes.
Get the floor plan
Ask the listing agent for the floor plan. It's usually a PDF or image attached to the listing. Any to-scale image works.
Upload and trace
Upload to MeasureFloorPlan and click around the exterior perimeter. Takes about 5 minutes for a typical home.
Get the real number
Enter one known wall length for scale. MeasureFloorPlan calculates ANSI-compliant GLA, the same methodology licensed appraisers use.
What to do with the number
If the number is off, you have options.
Negotiate the price
If the home is listed at $300/sq ft and measures 150 sq ft smaller than advertised, that is $45,000 in negotiating leverage. Use it.
Request an independent appraisal
Before closing, you can request your own appraisal. A licensed appraiser will measure the home and the discrepancy becomes part of the record.
Walk away informed
Sometimes the numbers are close enough that it does not matter. But you should know before you sign, not after.
