What is the difference between MeasureFloorPlan and iGUIDE?

MeasureFloorPlan is a browser-based tool for calculating ANSI-compliant GLA from existing floor plan images and PDFs. iGUIDE is a separate tool with different core functionality. The right choice depends on whether you need to measure from a floor plan or perform a different task.

Can MeasureFloorPlan replace iGUIDE?

It depends on your workflow. MeasureFloorPlan focuses on GLA calculation from floor plans: uploading an image, tracing the perimeter, and getting square footage. If iGUIDE serves a different purpose in your process, the two tools may complement each other rather than compete.

Which is better for ANSI Z765 GLA calculation, MeasureFloorPlan or iGUIDE?

MeasureFloorPlan is purpose-built for ANSI-compliant GLA calculation from floor plan images. It handles PDF uploads, perimeter tracing, and automatic area calculation in a browser with no install required. Whether iGUIDE offers equivalent GLA functionality depends on its feature set.

How much does MeasureFloorPlan cost compared to iGUIDE?

MeasureFloorPlan and iGUIDE have different pricing models. One may charge per user, per project, or via annual subscription, while the other may offer a free tier or pay-per-use option. Check the comparison table above for current pricing details and which offers better value for your volume of work.

Which is easier to use, MeasureFloorPlan or iGUIDE?

Ease of use depends on your starting point. MeasureFloorPlan tends to fit one type of user or workflow, while iGUIDE is designed for another. If you are working from an existing floor plan PDF and need to calculate square footage quickly, a browser-based tool like MeasureFloorPlan may reduce the learning curve entirely. No software installation required.

Do I need MeasureFloorPlan or iGUIDE if I already have a floor plan PDF?

If you already have a floor plan as a PDF or image, you may not need either tool. MeasureFloorPlan lets you upload the PDF directly and trace walls in your browser to calculate GLA. No software installation required. Both MeasureFloorPlan and iGUIDE are most useful for creating sketches from scratch or capturing measurements in the field.

Which works better for calculating GLA: MeasureFloorPlan or iGUIDE?

Both MeasureFloorPlan and iGUIDE can support GLA calculation, but the workflow differs. One may require field measurement and sketch entry while the other may allow importing existing floor plans. If your starting point is an existing PDF or image floor plan, MeasureFloorPlan provides a faster path. Upload, trace, and get the GLA figure without entering either tool's workflow.

How do MeasureFloorPlan and iGUIDE handle existing floor plan PDFs?

Neither MeasureFloorPlan nor iGUIDE is primarily designed to import and calculate square footage from an existing PDF floor plan. Both tools are built around creating or capturing floor plans from scratch. If you already have a PDF floor plan, MeasureFloorPlan lets you upload it directly, trace the walls, and get an accurate GLA figure without redrawing anything.

Which is better for occasional users, MeasureFloorPlan or iGUIDE?

MeasureFloorPlan and iGUIDE are both specialized tools with learning curves that reward regular use. Occasional users often find dedicated subscription tools hard to justify. For someone who needs to calculate square footage a few times a month, MeasureFloorPlan is designed for exactly that. No training required, no annual contract, upload and measure in minutes.

MeasureFloorPlan vs iGuide: Which Floor Plan Tool Is Right for Appraisers?

iGuide and MeasureFloorPlan are both used in real estate appraisal, but they solve different problems. iGuide captures precise floor plans on-site using a 360° camera and LiDAR sensor. MeasureFloorPlan measures and calculates GLA from a floor plan you already have. Knowing which problem you actually have will tell you which tool (or both) belongs in your workflow.

The short version

iGuide: Best when you need to capture a highly accurate, to-scale floor plan on-site. Requires the iGuide hardware kit.
MeasureFloorPlan: Best when you already have a floor plan: from iGuide, a builder, MLS, or elsewhere, and need to calculate or verify GLA without sketching software.

MeasureFloorPlan vs iGuide: at a glance

	MeasureFloorPlan	iGuide
What it does	Measures GLA from existing floor plans	Captures new floor plans on-site via LiDAR
Hardware required	Any device with a browser	iGuide camera + sensor kit (~$2,500+)
On-site presence	Not required	Required
ANSI GLA	Yes: trace and calculate	Yes: included in appraisal tier
Accuracy	Depends on source plan quality	± 1% LiDAR accuracy
Turnaround	Real-time (trace as you go)	Minutes after upload (cloud processing)
Per-use cost	$7-$25 in credits	$12–$25/scan + equipment amortized
Best for	Desk review, verification, existing plans	Field capture requiring high precision

What iGuide does

iGuide is a hardware-plus-software system that creates highly accurate 2D floor plans and 3D virtual tours from a property visit. You mount the iGuide sensor on a 360° camera, photograph each room from multiple positions, and upload to the iGuide cloud. The system generates a to-scale floor plan with LiDAR precision: typically within 1% of actual measurements.

The appraisal tier includes ANSI-compliant GLA calculations. iGuide is popular among appraisers, agents, and home stagers who need the most accurate field-captured floor plans available without manual laser measurements.

What MeasureFloorPlan does

MeasureFloorPlan is a browser-based tool for measuring GLA from an existing floor plan. You upload any PDF or image, set the scale using a known dimension on the plan, and trace the outline of each area. MeasureFloorPlan calculates square footage instantly and separates above-grade from below-grade areas for ANSI-compliant GLA reporting.

MeasureFloorPlan does not capture floor plans in the field: you need an existing plan to start. But it works with plans from any source: iGuide exports, builder blueprints, MLS attachments, county records, or prior appraisals.

When you need iGuide

iGuide is the right call when you are on-site and need the most accurate possible floor plan capture. If the property lacks a usable existing plan, the MLS data is unreliable, or your client demands a defensible as-built measurement with LiDAR backing, iGuide delivers. It is especially strong for complex floor plans, multilevel homes, and properties where tape-measure sketching would be time-consuming.

The upfront hardware cost ($2,500–$4,000 depending on camera) means iGuide makes the most sense for appraisers doing high volume or serving markets that justify premium deliverables.

When you need MeasureFloorPlan

MeasureFloorPlan is the right call when you already have a floor plan and need GLA fast. Common use cases: verifying a builder's stated square footage, calculating GLA from an iGuide export without paying for the appraisal-tier upgrade, reviewing a prior appraisal for a desktop review, or double-checking an agent's listed square footage before signing off.

At $9/month with no hardware requirement, MeasureFloorPlan is the lowest-friction option when the floor plan already exists.

Can you use both?

Yes, and it is a common combination. Capture the floor plan with iGuide in the field. Export the floor plan as a PDF. Upload to MeasureFloorPlan to trace and calculate GLA at your desk, bypassing the iGuide appraisal-tier fee. You get iGuide's precision capture plus direct control over how GLA is calculated without paying twice for the same work.

The bottom line

If you need to create a floor plan from scratch in the field, iGuide is one of the best tools available. If you already have a floor plan and need GLA calculated quickly and accurately, MeasureFloorPlan is the simpler, lower-cost option. Most high-volume appraisers will find value in having both.
