Floor Plan Generator: A Real Plan From Your Own Measurements
This floor plan generator starts from one of 88 drawn starter plans and regenerates it around the sizes you type: change a wall to 14 ft 6 in and the room, its area, the dimension lines and the furniture spacing update with it.
Free: draw, save in your browser, download a watermarked image. Paid: clean to-scale PDF and materials list.

|---|---|---|---|
| Two-bedroom | 29 ft 6 in × 23 ft | Living, 2 bedrooms, bath | 680 sq ft |
| One-bedroom | 23 ft 7 in × 19 ft 8 in | Living, kitchen, bedroom, bath | 465 sq ft |
| Studio | 21 ft 8 in × 16 ft 5 in | One room, bath | 355 sq ft |
| Tiny house | 24 ft × 8 ft | Living, kitchen, bath | 192 sq ft |
| Cottage | 31 ft 6 in × 26 ft 3 in | Living, kitchen, primary, bedroom, bath | 825 sq ft |
| Backyard ADU | 30 ft 2 in × 20 ft | Living, kitchen, bedroom, bath | 605 sq ft |
| In-law suite | 27 ft 7 in × 18 ft 4 in | Living, kitchen, bedroom, bath | 505 sq ft |
Sizes are to the outside of the walls as drawn; each plan reports the finished area of every room once you have typed your own lengths.
Layouts
Pick a layout
Each one opens in the canvas below with its sizes already drawn; change anything.
Two-bedroom, about 29 × 23 ft (680 sq ft)
Living room across the front, two bedrooms down one side, one bath. Change the outside walls first, then slide the bedroom wall until the second room fits your bed.
One-bedroom, about 24 × 20 ft (465 sq ft)
Open living and kitchen, bedroom and bath behind. The apartment and rental-listing starter; type the kitchen wall length before anything else.
Studio, about 22 × 16 ft (355 sq ft)
One room with a kitchen run and a corner bath. Move the bed first; the sofa back and the dining table are what divide the space.
Tiny house, 24 × 8 ft (192 sq ft)
Trailer width, kitchen in the middle, bath at the far end. Every wall is a few inches from a fixture, so check the bath door swing after each change.
Cottage, about 31 × 26 ft (825 sq ft)
Two bedrooms including a primary, kitchen and one bath. The smallest starter that reads as a house; stretch the depth to add a second bath.
Backyard ADU, about 30 × 20 ft (600 sq ft)
One bedroom, one bath, open front room. Sized for the common detached-unit cap; shorten the long wall to meet a stricter local limit.
In-law suite, about 28 × 18 ft (505 sq ft)
A one-bedroom unit meant to sit against a house or over a garage. Put the shared wall on the side with no windows, then set the entry door.
The two-bedroom starter with every wall length written on it. Click it, select a wall and type your own length; the plan regenerates around it.
About
Pick a two-bedroom, a studio or a backyard ADU below, type your real measurements, drag the rooms where you want them, and the result is a schematic plan with every wall length written on it and the clearances checked as you go. It does not invent a plan from a text prompt or a photo, and it is not an AI generator; it is a drawing engine that does the measuring and the counting for you.
01
How the generator works, in three steps
First, pick a starter from the cards above or from the 88 plans in the picker: homes, single rooms, bathrooms, basements, businesses and backyards. Second, select any wall and type its real length, in feet and inches or metres; the connected walls move with it, the room closes again and its square footage is recomputed. Third, drag rooms, doors and furniture into place. Nothing is approximate: the drawing is stored in millimetres and every piece is at its true size.
That is the whole trick. A plan is generated from measurements, not from a description, so the result matches the house you are standing in rather than a plausible one.
- Type lengths like 12 ft 6 in, 150 in, 3.8 m or 380 cm.
- Walls snap square and to each other, so corners stay closed.
- Switch units at any time; the plan does not drift.
- Undo every step; the plan autosaves in this browser.
02
Start from a plan, not a blank page
A blank canvas is the slowest way to a floor plan. The seven home starters above cover most small units people need to draw: a two-bedroom for a rental listing, a studio or one-bedroom for an apartment, a tiny house on a trailer, a cottage, a backyard ADU and an in-law suite. Each opens with doors, windows, a kitchen run, beds and a bath already placed, so the first ten minutes go into your dimensions instead of into furniture.
For a single room, the room-layout pages go deeper: bedroom-layout, living-room-layout, small-bathroom-layout and basement-layout each hold four to six fixed layouts of that one room at real sizes.
03
What gets generated for you
With wall lengths on, every wall carries its length on the plan; dimension lines run along the outside; each closed room shows its name and area in square feet or square metres. The paid materials list is counted from the same drawing: flooring and baseboard per room, paint, drywall sheets, studs at 16 inches on centre and plates for every wall, doors and windows.
As you move things, the clearance checks flag the rules the engine knows: 15 inches from a toilet centre to a wall and 21 inches in front of it, 24 inches in front of a shower and a 30 × 30 inch shower floor, a 42 inch kitchen aisle, 36 inches in front of a washer or dryer, 24 inches beside and at the foot of a bed, a door that swings into a fixture, and a ceiling under 7 ft (6 ft 8 in in a bathroom). Anything else, such as hallway width or furniture walkways, you measure on the plan with the dimension tool.

AI floor plan generators versus a drawn plan
AI generators are quick at ideas: type "two-bedroom, 800 square feet, open kitchen" and a plausible picture comes back in seconds, which is useful for a mood board. Their weakness is the part that matters for a real room: sizes that do not add up, doors drawn into walls or into each other, fixtures with no clearance, and an image you cannot edit once it exists. This generator trades the instant picture for a plan you can measure, change and print, built from your numbers. If you only want to see what a layout might feel like, an AI image is fine; if you need to know whether the queen bed fits, draw it.
05
Export, and what this is not
Drawing, saving in your browser and a watermarked PNG are free with no account. A clean PDF printed to scale, with a title block and scale bar, and the materials list CSV are paid per export. The plans are schematic: not stamped drawings, permit documents or quotes, and not an AI render of a room photo. Where a project needs professional drawings, bring this plan to the person who makes them; it is the fastest way to explain what you want. Drawing works best on a laptop or desktop.

Frequently asked questions
- Is there a free floor plan generator?
- Yes. Pick a starter plan, type your wall lengths and draw for free with no account; the plan autosaves in your browser and downloads as a watermarked PNG. The clean to-scale PDF and the materials list are paid per export.
- Can I generate a floor plan from my measurements?
- Yes, that is what this page does. Start from the closest starter, select each wall and type its measured length; the rooms, areas and dimension lines regenerate around the numbers you enter.
- Does this generate floor plans with AI?
- No. It is not an AI generator and nothing is produced from a text prompt or a photo. The plan is built from drawn starters and the sizes you type, by a drawing engine that measures and counts.
- Can I generate a 2 bedroom floor plan?
- Yes. The two-bedroom starter above is about 29 × 23 ft with a living room, two bedrooms and a bath. Type your outside walls first, then move the bedroom wall until the second bedroom holds your bed with 24 inches beside it.
- What size is a typical 2 bedroom floor plan?
- Most two-bedroom apartments and small homes run 700 to 1,100 sq ft; the starter here is about 680 sq ft gross. Bedrooms are usually 10 × 10 to 12 × 12 ft, the living room 12 × 16 ft or larger.
- Can I print the generated plan to scale?
- Yes, with the paid PDF export: it is laid out at a standard scale such as 1/4 inch to the foot or 1:50, with a scale bar, so lengths can be checked with a ruler on paper.
