Canvas vs iGUIDE: Which Floor Plan Tool Is Better for Appraisers?
Canvas and iGUIDE are two of the most capable 3D-scanning floor plan tools available for real estate professionals. Both produce accurate, to-scale floor plans, but they take very different approaches to hardware, pricing, and deliverables. Here is how to choose between them.
The short version
- Canvas: Best when you already have a compatible iPad with LiDAR. Flexible: you control the output. No recurring per-scan fees once you own the app.
- iGUIDE: Best for high-volume appraisal work that requires automatic ANSI-compliant GLA included with every scan. Higher hardware cost upfront.
Canvas vs iGUIDE: at a glance
| Canvas | iGUIDE | |
|---|---|---|
| Hardware required | iPad Pro with LiDAR (~$800) | PLANIX camera (~$2,500+) |
| Per-scan cost | Minimal (app one-time $30) | $15–$25+ |
| Floor plan delivery | On-device (minutes) | 2–4 hours (cloud processing) |
| ANSI GLA included | No (use PlanSnapper) | Add-on ($) |
| Best for | Lower-volume, flexible workflow | High-volume, automated GLA delivery |

Measure your floor plan →How Canvas works
Canvas (by Occipital) uses the LiDAR scanner built into iPad Pro models (2020 and later) to capture a 3D point cloud of a space. You walk through the property with the iPad, and Canvas processes the scan into a clean 3D model and 2D floor plan. The app runs entirely on-device: no subscription required beyond the one-time app purchase.
Canvas is flexible: you can export floor plans as PDFs, DXF files, or 3D models. For appraisal use, the PDF floor plan can be uploaded to a tool like PlanSnapper to calculate GLA. Canvas does not provide built-in ANSI-compliant GLA reports: that step happens downstream.
How iGUIDE works
iGUIDE uses its proprietary PLANIX camera: a dedicated 360° laser device. To capture floor plans and panoramic photos simultaneously. The camera connects to a smartphone app, and scans are uploaded to iGUIDE's cloud for processing. Delivered floor plans include automated square footage and, optionally, a certified ANSI Z765-compliant GLA report.
iGUIDE is purpose-built for real estate workflows. Every scan delivery includes a floor plan, 360° virtual tour, and room dimensions. The ANSI GLA add-on turns the output into an appraisal-ready document without any additional measurement work.
Hardware and cost
Canvas requires an iPad Pro with LiDAR (2020 or newer, starting around $800 new). The Canvas app costs a one-time fee of $29.99. Ongoing per-scan costs are minimal: you pay for the device, not each scan.
iGUIDE requires the PLANIX camera, which costs $2,500–$3,500 depending on the bundle. Per-scan processing fees apply (typically $15–$25+ per property). For low-volume users, total cost of ownership is substantially higher than Canvas.
Accuracy and ANSI compliance
Canvas achieves typical accuracy of ±1–3% for standard residential layouts using LiDAR. It is accurate enough for GLA calculations but does not produce ANSI-certified reports directly.
iGUIDE's laser-based system typically achieves ±1–2% accuracy. The ANSI GLA add-on provides a certified report signed off by iGUIDE's QA process: suitable for formal appraisal submissions without additional measurement steps.
Already have the floor plan?
If you are using Canvas to capture floor plans but want to calculate GLA yourself without waiting for a third-party add-on, upload the Canvas PDF to PlanSnapper and trace the perimeter. You get accurate GLA in minutes, ANSI-compliant calculations included.

Frequently Asked Questions
What is the difference between Canvas and iGUIDE?
Canvas and iGUIDE are different tools with different strengths. The best choice depends on your workflow, budget, and whether you need features like 3D scanning, floor plan generation, GLA calculation, or design capabilities. This page breaks down a direct comparison.
Which is better for real estate appraisers: Canvas or iGUIDE?
Canvas and Iguide serve different workflows. Canvas is better suited for one use case while Iguide fits another: the right choice depends on whether you need field capture or office-based GLA calculation from existing floor plans.
Can Canvas and iGUIDE be used together?
Canvas and Iguide can complement each other in some workflows: for example, using one for field capture and the other for GLA calculation and reporting. Check the comparison table above for specific integration details.
How much does Canvas cost compared to iGUIDE?
Canvas 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: Canvas or iGUIDE?
Ease of use depends on your starting point. Canvas 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 PlanSnapper may reduce the learning curve entirely: no software installation required.
Which is more accurate: Canvas or iGUIDE for floor plan measurement?
Both Canvas (using iPad LiDAR) and iGUIDE (using a proprietary LiDAR camera system) achieve high accuracy: typically within 1-2% of manual exterior measurement under good conditions. iGUIDE is generally preferred by appraisers for its floor plan data export and GLA-focused output. Canvas offers stronger 3D model quality and BIM export options suited to architecture and construction workflows.
Do Canvas or iGUIDE floor plans need to be verified against ANSI Z765 before use in an appraisal?
Yes. Both systems measure all interior spaces by default: they do not automatically separate above-grade from below-grade or exclude garages and porches. Appraisers using Canvas or iGUIDE floor plans must confirm that ANSI Z765 inclusion rules have been applied before reporting GLA. Uploading the exported floor plan to PlanSnapper and retracing the qualifying areas is one way to verify and document compliance.
Which is better for multi-family properties: Canvas or iGUIDE?
iGUIDE is commonly used for multi-family and larger residential properties because of its systematic room-by-room capture workflow and detailed floor plan output. Canvas is well-suited for single-family homes. For multi-unit buildings, the ability to generate a clear, labeled floor plan for each unit is important, and iGUIDE tends to have stronger export options for that use case.
What happens if Canvas or iGUIDE measurements differ from field measurements?
If a Canvas or iGUIDE-generated figure differs from the appraiser's exterior field measurements, the field measurement governs under ANSI Z765. Appraisers should note the discrepancy and use the exterior measurement for GLA. A difference of more than 2-3% warrants investigation to identify whether the scan, the field measurement, or the exclusion logic is the source of the gap.
