MeasureFloorPlan vs RoomScan Pro: Which Is Better for Floor Plan Measurement?
RoomScan Pro is an iOS app that uses your phone or iPad's LiDAR sensor to draw a floor plan while you walk through a property. MeasureFloorPlan is a browser tool that calculates square footage from a floor plan you already have: a PDF, a photo, or an export from any other source. They solve different problems. Here is when to use each.
Measure Your Floor Plan in Minutes
Upload a plan, set the scale with one known wall, and measure anything: wall lengths, room areas, and total size. Your first measurement is free, no signup required.
Upload Floor PlanThe short version
- RoomScan Pro: Best when you need to create a new floor plan on-site using LiDAR. You walk each room holding your phone to the walls, and it draws the layout automatically.
- MeasureFloorPlan: Best when you already have a floor plan: from CubiCasa, Matterport, an architect, a prior appraisal, or any other source, and need to measure GLA from it quickly and accurately.
MeasureFloorPlan vs RoomScan Pro: at a glance
| MeasureFloorPlan | RoomScan Pro | |
|---|---|---|
| Primary use | Measure GLA from an existing floor plan | Create a new floor plan on-site using LiDAR |
| Requires site visit | No: works from any to-scale image | Yes: LiDAR requires physical presence |
| Platform | Browser (desktop, laptop, tablet) | iOS only (iPhone/iPad with LiDAR) |
| ANSI Z765 GLA | Yes (above/below grade separation built in) | No (measures interior room dimensions only) |
| Accuracy | Within 1–2% of professional field measurement (from to-scale plan) | ±2–5% for LiDAR; interior only (excludes wall thickness) |
| Input | Photo, PDF, or image of any floor plan | Physical space (walks each room with phone) |
| Export | PDF report with GLA, address, and floor plan | DXF, PDF, PNG floor plan drawing |
| Price | $9 one-time or $29/mo unlimited | Free basic / $4.99–$9.99/mo Pro |
| Works without field visit | Yes | No |
What RoomScan Pro does well
If you are on-site and do not have a floor plan, RoomScan Pro is one of the fastest ways to create one. On newer iPhones and iPads with LiDAR, it can capture a room's shape in seconds by detecting walls automatically as you move the phone around the perimeter. It exports usable DXF and PDF floor plans suitable for quick sketches and listing prep.
For real estate agents preparing listing photos or investors doing quick assessments, RoomScan Pro is a solid field tool. The app is affordable and works well for interior layout documentation.
Where RoomScan Pro falls short for appraisers
- Interior dimensions only. LiDAR measures from interior wall surface to interior wall surface. ANSI Z765 requires exterior measurements: from exterior wall face to exterior wall face. That gap (roughly 6–12 inches per wall, times four walls) adds up to a meaningful difference in calculated GLA.
- No ANSI Z765 compliance. RoomScan does not know about above-grade vs below-grade separation, minimum ceiling height rules, or how to handle attics and split-levels under ANSI standards. Appraisers would need to apply those rules manually after export.
- Requires physical presence. If you already have a floor plan: from CubiCasa, Matterport, a prior appraisal, or the architect. There is no value in re-scanning. MeasureFloorPlan works from any image without a site visit.
- iOS only. RoomScan Pro requires a LiDAR-equipped iPhone or iPad (iPhone 12 Pro and later, iPad Pro 2020 and later). Android users and anyone on a laptop or desktop are excluded.
Where MeasureFloorPlan wins
- Works from any floor plan. CubiCasa, Matterport, iGUIDE, Apex Sketch exports, architect drawings, hand sketches: if it is a to-scale image, MeasureFloorPlan can measure it. No site visit required.
- ANSI Z765 compliant GLA. MeasureFloorPlan uses exterior perimeter measurements and calculates above-grade and below-grade areas separately: matching the methodology required for appraisal reports.
- Works on any device. Desktop, laptop, or tablet. No iOS LiDAR sensor required.
- Better for existing floor plans. Most appraisers already have a floor plan from a scan service, a builder, or a prior report. MeasureFloorPlan turns that into a ANSI-compliant GLA number in under two minutes without stepping foot on the property again.
Can you use them together?
Yes, and this is actually a strong workflow. Use RoomScan Pro on-site to capture the floor plan layout quickly, then export it as a PDF. Upload that PDF to MeasureFloorPlan to trace the exterior perimeter and calculate a proper ANSI-compliant GLA. You get the speed of LiDAR field capture combined with the accuracy and methodology compliance of MeasureFloorPlan.
Just remember: RoomScan captures interior dimensions, so your exported PDF will reflect interior wall-to-wall distances. When you trace in MeasureFloorPlan, you are tracing the floor plan as drawn: which means you should add approximate wall thickness to get true exterior GLA if precision is critical.
Who should use which tool
- Use RoomScan Pro if you are on-site without a floor plan and need to create one fast from LiDAR
- Use MeasureFloorPlan if you already have a floor plan and need to calculate ANSI-compliant GLA from it without a site visit
- Use both if your workflow involves capturing layouts on-site (RoomScan) and then computing GLA for reports (MeasureFloorPlan)
