Free interior design software
Most people typing this want one of three different things: a room layout drawn to scale, a picture of the finished room, or a floor plan they can hand to a contractor. Almost no single free tool does all three well, so it helps to know which one you are actually after before you download anything.
Interior design
What people mean by free interior design software
The phrase covers three jobs that have almost nothing in common. One person wants to know whether a sectional fits between the fireplace and the doorway - that is a layout problem, measured in inches. Another wants to see the room finished in a style before committing to paint and a rug - that is a picture problem. A third needs a dimensioned plan a builder can price - that is a document problem.
Tools that are good at one of these are usually mediocre at the other two, and the free version of each is limited in a different place. Knowing which job you have saves the afternoon you would otherwise spend learning a program that was never going to answer your question.
This page lays out what the free options actually cover, where the free tier usually stops, and what you can do here without paying. We sell a paid product, so treat the last part accordingly - the honest boundaries are written out rather than buried.
Want it exact? Draw the room in the free 3D editor
A Sims-like builder in your browser: walls, roof, windows, door, porch. Try finish materials (siding, stucco, brick), color and style. The result is a photorealistic AI render of your own 3D scene.
Which of the three jobs do you have
Match the question you are actually asking to the kind of tool that answers it. Picking the wrong category is the single most common reason people conclude that free design software is useless.
| Your question | What you need | What to look for |
|---|---|---|
| Will this furniture fit? | A layout drawn to scale | Real dimensions in feet and inches, wall thickness, furniture at true size |
| What will it look like finished? | A render or visualization | Style control, believable lighting, output big enough to actually look at |
| What do I hand the contractor? | A dimensioned floor plan | Printable export, room labels, square footage, an export that is not watermarked |
| Which paint and which sofa? | Comparison, not construction | Fast iteration - you want ten versions, not one perfect model |
| All of the above, eventually | Two tools, not one | A layout tool plus a render tool beats one program that half-does both |
Start with the cheapest question
If you are early, do the layout first. A render of a room whose furniture does not fit is a nice picture of a plan you cannot build.
The categories of free interior design tools
Rather than a ranking that goes stale, here is how the field divides. Any tool you find will sit in one of these, and its free tier will be limited in the way its category is usually limited.
- Browser-based room planners — Draw walls, drop in furniture, switch to 3D. Free tiers are generous on drawing and stingy on output - expect limits on export resolution, watermarks, or a cap on saved projects. Best for the fits-or-not question.
- Desktop modeling software — Full 3D modeling that happens to be used for interiors. Enormously capable and correspondingly slow to learn; the free versions are real but assume you will invest time. Overkill unless you are doing this repeatedly.
- AI render tools — Upload a photo, get the room redrawn in a chosen style. Fast and good at the what-will-it-look-like question, useless for the will-it-fit one, because most of them do not know the dimensions of your room.
- Retailer room planners — Free, well made, and restricted to that retailer's catalog. Genuinely useful if you have already decided where you are buying, and a dead end if you have not.
- Mood board and swatch apps — Not design software in the layout sense, but the right tool for comparing finishes and building a palette. Free almost everywhere because the cost of running them is near zero.
Where free usually stops
Free tiers are not dishonest, but they are all limited somewhere, and it is rarely on the feature you notice first. These are the four places to check before you invest an evening.
What is free here, written out
Our own boundaries, in the same terms. The planner is free because it costs us almost nothing to run; the AI renders are paid because they do not.
Drawing to scale
Walls, doors, windows and partitions at exact sizes in feet and inches, snapped to a grid. No limit, no trial clock.
3D and walkthrough
Switch the layout to 3D and walk it at eye level. Free, including the camera controls and saved views.
Furniture at true size
Place from the library and check clearances. Free, and the dimensions are real rather than decorative.
Saving and sharing
Projects live on your account and open on any device. A public link opens without the other person signing up.
Two AI renders
Every new account gets a couple of generations, so you can see the paid part before deciding about it.
What is paid
Further photorealistic renders, AI furniture arrangement, and turning a photo of a real piece into a 3D model.
The part that is not free, and why
Drawing a plan is arithmetic - a browser does it for free. Turning that plan into a photorealistic room is a model run on a GPU, and it costs real money every time you press the button. Any tool offering unlimited free renders is either subsidizing you temporarily or producing something much cheaper than it looks.
We charge for the renders and nothing else, which is why the layout side has no limits at all. If all you need is to know whether the bed fits, you will never reach a paywall here.
- 1
From a photo
Shoot the room from the doorway and the model redraws it in a chosen style, keeping the windows, the proportions and the openings where they are.
- 2
From your plan
If you drew the layout, the render follows it - the furniture ends up where you put it, not where a stock image had it.
- 3
Region edits
Happy with everything except one corner? Select that area and change only it, instead of rerolling the whole room.
A useful test of any free design tool
Ask what it costs the company to give you the thing you want. Drawing is cheap and tends to stay free. Rendering, storage and real product catalogs are not, and that is where every free tier eventually stops.
Design a room free in three steps
Nothing to install. It runs in a browser on a laptop, tablet or phone, and you can start without an account.
Draw the room or upload a photo
Click the corners to build walls at real dimensions, or drop in a photo of the room if you only want the picture. Either path is free.
Put the furniture in
Place pieces from the library at true size and check the walkways. This is where the fits-or-not question gets answered, and it costs nothing.
Look at it in 3D
Switch modes and walk it at eye level. If you then want a photorealistic version, that is the paid step - and the first couple are on the house.
What the free side produces
These are model-generated reference frames rather than photographs of finished projects. They show the range of styles, not a promise about your specific room.
Layout in 2D
Walls at real dimensions with room labels and square footage. The sheet you print and take to the contractor.
Make one like thisThe same room in 3D
One click from the flat drawing. Useful for headroom, sightlines and whether a walkway feels tight.
Make one like thisFurniture at true size
An 84-inch sofa takes 84 inches. Obvious, and the thing most free tools quietly fudge.
Make one like thisAI render from the plan
The paid step: the same layout as a photorealistic room, in the style you asked for.
Make one like thisBrowser tool or desktop download
The oldest split in this category, and the one that decides most of the experience. Neither is wrong; they suit different jobs.
| Runs in a browser | Desktop download | |
|---|---|---|
| Time to first result | Minutes | An evening, at least |
| Works on a tablet | Usually yes | Rarely |
| Ceiling on complexity | Lower - a house, not a high-rise | Very high |
| Machine requirements | Almost none | Real ones, especially for rendering |
| Where the free tier bites | Export and render count | Learning time, and commercial licensing |
| Best for | One room, one decision, this weekend | Repeated professional work |
If you are doing this once
Pick the browser. The learning curve of desktop software is a real cost, and you only get it back if you use the tool again.
How to check a free tool in ten minutes
Run this before you commit an evening. Every item is something you can test with a throwaway project.
Export something immediately
Make a single square room and try to get a PDF or an image out. If that is paid, you have learned it now rather than at the end.
Type a real dimension
Set a wall to 12 ft 4 in and see whether the tool takes it. Some free planners only snap to whole units, which is fine until it is not.
Put in the biggest thing you own
Your actual sofa or bed, at its actual size. If the library has nothing near it, layout answers will be wrong in the direction that matters.
Save and reopen
Close everything, come back, and check the project is still there and still editable. Free tiers sometimes keep the file and not the editability.
Read the license line
One sentence, usually. Personal use only is fine for your home and useless for client work.
Try it on the device you will use
A tool that is lovely on a desktop can be unusable on the tablet you actually design on in the evening.
