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

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.

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.
