How to Convert a Hand-Drawn Floor Plan to Digital — 3 Options Compared
You have a hand-drawn sketch or an old paper floor plan. You need a clean digital version.
There are three ways to do it. Each one fits a different situation, budget, and deadline. This article covers all three — what’s involved, what you get, and when each one makes sense.
Key Facts
– Three main ways to convert a hand-drawn floor plan to digital: a digitization service, DIY CAD software, or hiring an architect/draftsperson
– Digitization service: 1–3 day turnaround, fixed area-based pricing
– DIY tools (RoomSketcher, Floorplanner): time investment, learning curve, no DWG output on free tiers
– Architect / CAD draftsperson: highest price, longest timeline, best when design changes are needed
– The DWG format is the standard CAD format readable by AutoCAD and most engineering software (Autodesk)
– Replanera delivers all three formats — JPG, PDF, DWG — at the same price
The Three Options
- DIY floor plan software — you redraw the plan yourself using an online tool
- AI conversion tools — you upload the image and software auto-traces it
- Professional digitization service — you send the drawing, a human redraws it for you
The right choice depends on your technical comfort, how accurate the result needs to be, and what file format you need at the end.

Option 1: DIY Floor Plan Software
You open a tool, enter your measurements, and draw the plan yourself. The software handles the visual output.
How it works
Tools like Floorplanner, RoomSketcher, and Planner 5D let you build a floor plan by placing walls, doors, and windows on a grid. You enter your measurements manually. The result is a clean digital floor plan you can download.
What you get
- A JPG or PDF image suitable for property listings or visual use
- An editable file within the tool’s own format
- Basic room labels and dimensions if you add them
What you don’t get
- A DWG file (most DIY tools don’t export to DWG)
- A CAD file an engineer or architect can work with
- A result that matches your original drawing automatically — you build it from scratch
Realistic time to complete
For someone who hasn’t used these tools before: 2–4 hours for a standard apartment. The software is not difficult, but there is a learning curve. Getting walls aligned, doors placed correctly, and dimensions looking clean takes longer than expected the first time.
What it costs
Most tools offer a free tier with limited features and lower-resolution exports. A single floor plan download typically costs $5–20, depending on the platform and quality level.
Best for
Someone who has the time, needs a basic visual for a listing, and doesn’t need a DWG file.

Option 2: AI Conversion Tools
You upload a photo or scan of your existing drawing, and the software tries to detect the walls, rooms, and dimensions automatically.
How it works
Tools like Magicplan and CubiCasa use computer vision to read a floor plan image and generate a digital version from it. The idea is to remove the manual redrawing step entirely.
What you get
- A rough digital version of your drawing, generated in seconds
- An editable result in the tool’s own format
- Export options vary — typically JPG and PDF; DWG is usually not available
What you don’t get
- Consistent accuracy. AI reads what it can see. If your drawing has faded lines, ambiguous corners, or handwritten dimensions in non-standard positions, the output will reflect those problems.
- A file you can submit for a building permit or hand to a contractor
Realistic accuracy
AI tools work reasonably well for clean, printed floor plans from a recent source. For hand-drawn sketches — irregular line weights, non-standard symbols, handwritten notes in the margins — accuracy drops. You will usually need to correct errors manually, which puts you back at Option 1 anyway.
What it costs
Free tiers are available on most AI tools. Paid plans that produce usable exports typically cost $15–30 per floor plan.
Best for
Quick visual estimates where exact accuracy is not critical. Not suitable for construction use, permit applications, or any project where measurements need to be correct.

Option 3: Professional Digitization Service
You send your drawing — a sketch, a photo, a PDF. A professional redraws it in CAD software and sends back a finished file.
How it works
You upload your drawing and enter the floor area. You get a price. If you proceed, a drafter rebuilds your floor plan from scratch using professional CAD software — your drawing as the source, confirmed measurements as the guide.
The result is not a trace of your image. It is a properly constructed technical drawing.
What you get
- A clean, accurate floor plan at correct dimensions
- JPG and PDF for visual use and documentation
- DWG for construction, engineering, and architectural projects
- Free revisions until the result matches your expectations
What you don’t get
- Instant output — standard delivery is 1–3 business days
Realistic accuracy
As accurate as the measurements you provide. If your sketch has all rooms dimensioned, the finished plan will match. If some dimensions are unclear or missing, the service will ask you to confirm them before starting. No guessing.
What it costs
Professional floor plan digitization typically costs €15–40 per floor, depending on size and complexity. The Replanera price calculator gives you an exact quote based on your floor area — takes under a minute.
Best for
Property listings where the floor plan will be seen by buyers. Building permit applications. Construction, renovation, or engineering projects. Any situation where accuracy and file format matter.

Which Option Should You Choose?
Choose DIY software if: You have a few hours, the plan is simple, and you only need a JPG or PDF for a listing.
Choose AI tools if: You have a clean printed plan, need a rough digital version quickly, and don’t need precision or DWG.
Choose a professional service if: The floor plan will be used for a property listing where you want it to look right, a building permit application, a renovation project, or any situation where a contractor, engineer, or architect needs to work with the file.

What to Have Ready Before You Order
If you go with a professional service, you need:
- A clear photo or scan of your drawing. A phone camera in natural light is fine. Make sure the whole drawing fits in the frame and the handwriting is readable.
- Dimensions for all rooms. Width and length. Approximate measurements are acceptable for most uses — you don’t need millimetre precision.
- A note on intended use. Property listing? Building permit? Renovation? This determines which format and level of detail you need.
That’s the full list. For a standard apartment, collecting these takes 20–30 minutes.

Frequently Asked Questions
Can I convert a very old drawing — from the 1960s or 1970s?
Yes. Age is not the issue. A drawing from 1965 can be digitized as long as the lines are readable and you can confirm any dimensions that have faded. We work with old drawings regularly.
My sketch doesn’t have all the measurements. Is that a problem?
Not necessarily. Mark what you have. If key dimensions are missing, we’ll ask you to measure those specific walls — a tape measure and 20 minutes usually covers it.
What if I just have a phone photo of my floor plan?
That works as the source material for a professional service. Take the photo in good natural light, make sure the whole plan is in frame, and check that the handwriting is legible.
Do I need to know the total floor area before I can get a price?
An approximate area is enough. Most people know the rough size of their apartment or house. If you’re not sure, a quick calculation from room dimensions will do.
Is a digitized floor plan the same as an architect’s drawing?
No. A digitized floor plan is a clean representation of an existing layout. An architect’s drawing — for a new building or a structural modification — is a different document, produced by a licensed architect. Digitization converts what already exists. It does not design or certify.
