SketchUp vs AutoCAD for Floor Plans: Which Is Better for Real Estate?
SketchUp and AutoCAD are professional-grade design tools, not real estate measurement tools. But both are used to create floor plans, especially in new construction, architecture, and high-end residential work. Here is how they compare for producing floor plans and calculating square footage.
The short version
- SketchUp: Easier to learn, 3D-first, better for conceptual design. Free tier available. More common in residential design.
- AutoCAD: Industry standard for technical drawing. Steeper learning curve. More precise and widely accepted for construction documentation.
SketchUp vs AutoCAD: at a glance
| SketchUp | AutoCAD | |
|---|---|---|
| Primary use | 3D modeling + floor plans | Technical 2D/3D CAD drawing |
| Learning curve | Moderate | Steep |
| Free tier | Yes (web) | No (30-day trial) |
| Annual cost | ~$349/year (Pro) | ~$465/year (LT) |
| Best for | Residential design, visualization | Construction documentation |
SketchUp for floor plans
SketchUp is primarily a 3D modeling tool, but it's widely used for 2D floor plan creation because of its accessible interface. The free web version (SketchUp Free) can produce basic floor plans. SketchUp Pro (~$349/year) adds more export options and LayOut for professional floor plan sheets.
For residential design and real estate visualization, SketchUp is typically faster to work with than AutoCAD. The learning curve is gentler and the output looks polished.
AutoCAD for floor plans
AutoCAD is the industry standard for architectural and engineering drawings. For precise, construction-ready floor plans with exact dimensions, layer control, and standardized symbols, AutoCAD is unmatched. It also has the broadest compatibility with downstream workflows (structural, MEP, etc.).
AutoCAD LT (~$465/year) is a 2D-only version that covers floor plan creation without the full 3D modeling overhead. The learning curve is steeper than SketchUp, and the interface is less intuitive for non-engineers.
Square footage from each
Both tools can calculate area automatically. In SketchUp, you can use the area measurement tool on any surface. In AutoCAD, the AREA command or HATCH properties give exact area figures. Both are accurate to the precision of the input geometry.
For ANSI-compliant GLA from either tool, the measurement is only as accurate as the underlying floor plan data.
Already have the floor plan?
If someone hands you a floor plan PDF exported from SketchUp or AutoCAD, PlanSnapper gives you the fastest way to calculate the square footage without needing the original software or knowing how to use it. Upload the PDF, set the scale, trace the area.
