Canvas vs RoomSketcher: iPad LiDAR vs Browser Floor Plan Tool
Canvas scans physical spaces using iPad Pro LiDAR to generate 3D models and dimensioned floor plans automatically. RoomSketcher is a web app where you draw floor plans manually by entering measurements. Both produce useful outputs: for very different use cases and budgets.
The short version
- Canvas: Best for capturing existing spaces in 3D: renovation contractors, interior designers, real estate photographers adding floor plans to listings.
- RoomSketcher: Best for designing or documenting floor plans when you already have the measurements: real estate listings, home staging, light architectural work.
Canvas vs RoomSketcher: at a glance
| Canvas | RoomSketcher | |
|---|---|---|
| How it works | iPad Pro LiDAR scan, auto-processed | Manual drawing in browser |
| Hardware required | iPad Pro with LiDAR (2020+) | Any browser |
| Output | 3D model + dimensioned 2D floor plan | 2D floor plan, 3D visualization |
| Accuracy | ±1–2% (LiDAR-based) | As accurate as your measurements |
| ANSI GLA support | No (not appraisal-focused) | No (not appraisal-focused) |
| Pricing | ~$8–$16/scan + app (subscription) | Free limited / $49–$99/mo pro |
| Best for | Capture of existing spaces | Drawing from known measurements |

Measure your floor plan →Workflow: capture vs draw
Canvas removes the measuring step entirely. Walk through each room slowly with your iPad Pro and the app builds a 3D point cloud as you go. After processing, you get a dimensioned floor plan and a 3D model that can be exported to common CAD formats.
RoomSketcher works the opposite way. You enter your room dimensions (from a tape, laser measure, or an existing plan), place walls and doors, and the app renders the result. It is essentially a drag-and-drop floor plan drawing tool with a polished interface.
Accuracy
Canvas is consistently within 1–2% of hand measurements on simple rectangular rooms. Complex shapes, alcoves, and rooms with lots of furniture can reduce accuracy. You still need to review and correct obvious errors.
RoomSketcher is only as accurate as what you put in. If you measure correctly, the floor plan is correct. If you estimate or pull from county records (which are often wrong), the output reflects those errors.
Cost breakdown
Canvas requires an iPad Pro: a $1,000+ hardware investment before you spend anything on the app. Scans typically run $8–16 each depending on your plan. For real estate photographers doing multiple listings per week, the cost-per-scan is manageable.
RoomSketcher has a free tier with limited features. The Pro plan runs $49–99/mo depending on what you need. For agents drawing floor plans for listings, the subscription pays for itself quickly if it saves time on even a few deals.
When to choose Canvas
- You need to capture a space you have never seen a floor plan for
- You do renovation or remodeling work and need as-built documentation
- You want 3D output, not just a 2D plan
- You already own an iPad Pro and want to get more out of it
When to choose RoomSketcher
- You already have measurements or a sketch and just want clean output
- You are creating floor plans for real estate listings
- You want 3D renders for staging, marketing, or client presentations
- You do not want to carry hardware to every property
The PlanSnapper angle
Neither Canvas nor RoomSketcher calculates GLA for appraisal purposes. If you have a floor plan PDF from either tool and need to measure square footage or calculate ANSI-compliant GLA, PlanSnapper handles that in minutes: upload the plan, trace the perimeter, and get the number.
Already have the floor plan?
Upload any floor plan PDF or image and calculate GLA in minutes.

Frequently Asked Questions
What is the difference between Canvas and RoomSketcher?
Canvas and RoomSketcher 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 RoomSketcher?
Canvas and Roomsketcher serve different workflows. Canvas is better suited for one use case while Roomsketcher fits another: the right choice depends on whether you need field capture or office-based GLA calculation from existing floor plans.
Can Canvas and RoomSketcher be used together?
Canvas and Roomsketcher 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 RoomSketcher?
Canvas and RoomSketcher 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 RoomSketcher?
Ease of use depends on your starting point. Canvas tends to fit one type of user or workflow, while RoomSketcher 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.
Do I need Canvas or RoomSketcher 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. PlanSnapper lets you upload the PDF directly and trace walls in your browser to calculate GLA: no software installation required. Both Canvas and RoomSketcher are most useful for creating sketches from scratch or capturing measurements in the field.
Which works better for calculating GLA: Canvas or RoomSketcher?
Both Canvas and RoomSketcher 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, PlanSnapper provides a faster path: upload, trace, and get the GLA figure without entering either tool's workflow.
How do Canvas and RoomSketcher handle existing floor plan PDFs?
Neither Canvas nor RoomSketcher 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, PlanSnapper lets you upload it directly, trace the walls, and get an accurate GLA figure without redrawing anything.
Which is better for occasional users: Canvas or RoomSketcher?
Canvas and RoomSketcher 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, PlanSnapper is designed for exactly that: no training required, no annual contract, upload and measure in minutes.
