Floor plan generator from room sizes
How to use it
- In the panel Add a room by size, type the width and length of the first room and press Add.
- Add the next rooms the same way; each new room is placed beside the plan. Drag a room against another and it snaps so they share one wall.
- Rename rooms, change the floor (wood, tiles or plain) and the wall thickness in the room panel.
- Or start from a template: bedroom, living room, bathroom, studio flat or a one-bedroom flat.
A generator you can still edit
PlanPencil does not guess a layout for you: it turns the sizes you type into a plan you control. Every number on the plan comes from those sizes, so the area of each room and the total are exact for what you entered. If you have a hand sketch with measurements, this is the quickest way to turn it into a clean plan.

Questions
Do I need an account?
No. You draw, save and download without one. Your plan is saved in this browser on this device as you draw; download a project file to keep a copy or move it to another device.
Metres or feet?
Both. Switch between m and ft at any time; sizes accept 4.2, 420 cm or 13′ 9″.
What can I download for free?
A PDF printed to scale (1:20 to 1:500, A4 or Letter), PNG pictures of the plan or the depth view, an SVG drawing and a project file. No watermark.
Is the plan exact enough for a builder?
The plan is as exact as the sizes you type. It is for planning and showing ideas, not a building drawing for permits.
