Sketch to Floor Plan — Convert Hand-Drawn and Old Plans to Digital Format
Roomagen Sketch to Floor Plan is an AI digitization tool that converts photos of hand-drawn sketches, napkin drawings, and rough layouts into clean, professional digital floor plans — used by architects, designers, agents, and homeowners for space planning and documentation.
Hand-drawn floor plans and paper sketches are still the fastest way to capture initial layout ideas — architects sketch on napkins, homeowners draw on graph paper, agents receive hand-drawn plans from sellers. But these sketches are unprofessional for presentations, impossible to share digitally, and cannot be edited or measured precisely. Professional CAD digitization costs $50–$200 per floor plan and takes 1–5 days. Learning CAD software (AutoCAD, SketchUp) requires weeks of training. Roomagen converts any photographed sketch into a clean digital floor plan in under 90 seconds for 2 credits.
No credit card required. Results usually in under a minute.

Frequently Asked Questions
Everything you need to know about Roomagen
Any hand-drawn floor plan: napkin sketches, graph paper layouts, whiteboard drawings, old paper blueprints, notebook doodles, or rough pencil layouts. The AI interprets walls, doors, windows, and room labels from your drawing.
The AI follows the room layout and proportions of your sketch, but it redraws everything, so check the result. Measurements you write on the sketch are kept by default but redrawn, not copied, and unreadable ones are left out. Accuracy depends on how clear and detailed the sketch is.
Not perfectly, but clearer sketches produce better results. Use straight-ish lines for walls, mark doors with arcs, and label rooms if possible. The AI handles imperfect hand-drawing well but cannot interpret extremely messy or overlapping lines.
Yes. Photograph or scan old paper blueprints and upload them. The AI extracts the floor plan layout and generates a clean digital version. Works with faded, yellowed, or partially damaged documents.
Roomagen generates high-resolution digital floor plan images with clean lines, room labels, and professional formatting. Output is immediately usable in presentations, listings, and documents.
