Online floor plan drawing from a sketch: what you get back
A sketch to floor plan converter turns a photo of a hand-drawn floor plan into a clean digital plan. FloorDrafter keeps the walls, openings, room labels and written measurements as you drew them, straightens the lines, and returns a PNG, a DXF for CAD, or a plan to keep editing.
Fixed for you
- Wobbly freehand lines become straight walls with true corners
- A sheet photographed at an angle is squared up
- Paper, grid lines, creases, glare, hands and the table are removed
- Pencil or pen texture becomes clean linework
Not done here
- Measuring your house: the plan is only as accurate as the numbers you wrote
- Inventing dimensions where you wrote none
- Redesigning the layout, unless you ask for it
- Permit or construction drawings
What you can upload
Graph-paper and notebook sketches, napkin drawings, a whiteboard photo, a scanned or faded paper plan, an existing floor plan image, or a building plan for a small office or shop. Not a photo of the room itself: the converter redraws drawings, it does not survey spaces. JPG, PNG, WEBP or PDF, straight from your phone.
Examples
One floor plan sketch, three ways out
Same phone photo, three instructions. The input never changes: a ballpoint sketch on graph paper with 4.20 m and 3.5 m written on the walls, photographed on a desk. What changes is the sentence underneath, and that sentence decides which floor plan comes back.
What FloorDrafter returns, depending on what you ask
Clean CAD drawing, exactly as drawn
Furnished colour plan
Dimensions added in feet
How to convert a sketch to a floor plan online
Three steps, about a minute of waiting, no CAD skills.
- 1
Photograph the sheet
Lay the sketch flat, fill the frame with the paper and shoot from straight above in even light. A phone photo, a scan or a whiteboard picture all work, and so does a PDF.
- 2
Choose the output
Upload the photo and pick Clean CAD for a black-and-white drawing, Colored plan for tinted rooms, or Furnished 2D for furniture. Add a note only if something should change, such as dimensions in feet.
- 3
Download, export or keep editing
Get the PNG, export a DXF with the walls, doors and windows for AutoCAD or Revit, or mark the next change on the paper in red and upload it again.
Sketch to floor plan with dimensions
Numbers you write on the sketch are copied, not measured, so the plan is as accurate as your tape measure. Here is what each situation gives you.
| What you write on the sketch | What comes back |
|---|---|
| 4.20 m on the living-room wall | That wall is drawn to 4.20 m and the number is kept as a dimension line. |
| Nothing on the bathroom walls | They keep the proportions you drew, relative to the walls that do have numbers. |
| Only room names, no numbers at all | A proportional plan with labels. Ask for dimensions in feet or in metres and every room gets dimension lines in that unit. |
| 12 ft on one wall, 3.5 m on another | Both are respected. Say which unit you want on the finished plan. |
| Export DXF | Walls, doors and windows as lines in metres, scaled from a standard 0.9 m door. Text and dimension figures are not part of the DXF. |
For a scaled survey of an existing building you still need a measured plan. This converter draws what you sketched.
How to make a quick floor plan sketch the AI reads cleanly
You do not need to draw neatly. These six habits are what separate a one-shot conversion from a retry.
- 01
Fill the frame with the paper
Table, hands and clips outside the sheet confuse the read. Crop before uploading if you can.
- 02
Shoot from straight above, in even light
An angled shot gets squared up, but a straight one always converts cleaner.
- 03
Ink over pencil
Faint graphite on grid paper is the most common reason a wall goes missing.
- 04
Write a number on the walls that matter
Outer walls first. One number per wall is enough; the rest is drawn in proportion.
- 05
Draw doors as gaps with a swing, windows as a double line
Standard symbols are read more reliably than the word door written next to the wall.
- 06
Decide wall thickness before you start
Outer walls thick, inner walls thin, and keep it consistent across the sheet. Advice from a homeowner who got three renovation permits from sketches like these.
Download a PNG, export DXF, or keep editing on paper
Every conversion is a high-resolution PNG; downloads made before you pick a plan carry a small watermark.
PNG for sharing and printing
Drop it into a listing, a message to your contractor or a slide. To hand someone a PDF, print the PNG to PDF from your browser.
DXF for AutoCAD and Revit
Export the walls, doors and windows as lines, in metres, and carry on in CAD. Room names and dimension figures stay on the PNG.
Changes without redrawing
Mark the change on the paper in red: cross out a wall, draw a new opening, write bathroom here. Photograph it again and upload both, or type the change in the editor.
AI converter vs. drawing it yourself vs. a redraw service
Three ways to get from a sketch to a floor plan, and what each one asks of you.
| FloorDrafter converter | Drag-and-drop editors | Human redraw service | |
|---|---|---|---|
| You supply | A phone photo of the sketch | Your time: trace every wall, type every length | The sketch plus measurements, then you wait |
| Time to a plan | About a minute | One to three hours for a first plan | Same day to a few days |
| Cost | 3 credits per plan; Pro at $19 a month covers about 50 plans | Free tiers save one plan; paid from about $10 a month | From about £18 per plan |
| Output | PNG; DXF of walls, doors and windows; changes by marking the paper | Fully editable vectors, PDF and DXF, to-scale print | A PDF or JPEG plan drawn to your numbers |
| Best for | Planning, listings, contractor conversations, first drafts | Exact drawings you will keep revising in software | Listing plans when you do not want to touch software |
Who converts sketches into floor plans
Homeowners planning a renovation
Sketch the current layout, convert it, then mark the new kitchen on the paper and convert again.
Agents, landlords and short-let hosts
A listing-ready plan from the sketch you made at the viewing, without a CAD operator.
Contractors and tradespeople
A clean drawing of the site sketch to send with the quote, the same afternoon.
Students and designers
Get the napkin idea into a clean 2D before opening CAD, and keep iterating on paper.
Sketch to floor plan: questions people ask
Straight answers about accuracy, dimensions, formats and cost.
Photograph the sketch, upload it here, pick Clean CAD, Colored plan or Furnished 2D, and download the result in about a minute. Leave the instruction box empty to get the sketch back exactly as drawn, or add a note such as "add dimensions in feet".
Yes. FloorDrafter reads the walls, openings, labels and written numbers on your sketch and redraws them as a clean plan. It does not invent rooms or move walls you drew. If a result is off, upload a straighter photo or write the wall sizes on the sketch and convert again.
Three credits per plan at standard quality (2K) and six at 4K. Pro is $19 a month for 150 credits, about 50 plans; Studio is $39 for 400; a 100-credit pack is $29. You can run a couple of conversions before choosing a plan, and those downloads carry a small watermark.
Yes. A number written on a wall sets that wall's length and is kept as a dimension line; walls without a number keep the proportions you drew. Ask for dimensions in feet or metres and every room gets dimension lines in that unit.
No app. Open this page on your phone, tap the upload box to take a photo of the sketch, and the converter runs in the browser. The result downloads to your phone like any other image.
You download a PNG; print or save it as a PDF from your browser. For CAD, export a DXF that contains the walls, doors and windows as lines in metres, ready to open in AutoCAD or Revit. There is no DWG export.
Yes, that is what this page is for. Draw the layout on paper with a few measurements, photograph it and convert it. A two-bedroom flat or a two-storey house works the same way, one sheet per floor.
No. It is a clean drawing of what you sketched, not a measured survey. Use it for planning, listings and conversations with contractors, and have a licensed professional produce the permit drawings.
