Need a floor plan but don’t want to pay for AutoCAD or hire an architect? I spent two weeks testing every free floor plan tool I could find online. Some were garbage. A few were surprisingly good. Here’s what actually works in 2026.
Whether you’re rearranging furniture, planning a renovation, or sketching out a new apartment layout, these tools let you draw accurate floor plans without spending a dime. I tested each one by recreating my own 65 sqm apartment – same rooms, same dimensions, same furniture placement.

1. Floorplanner – Best for Quick 2D/3D Layouts
Floorplanner is the tool I keep coming back to. The drag-and-drop interface feels natural – you draw walls by clicking, drag to set length, and rooms snap into shape within seconds. I had my apartment’s basic layout done in about 12 minutes.
The free plan gives you one project with unlimited rooms. That’s enough for most people who just need to plan a single home or apartment. You get access to a furniture library with thousands of items (sofas, tables, appliances, bathroom fixtures), and you can switch between 2D and 3D views instantly.
The 3D rendering on the free tier isn’t photorealistic, but it’s good enough to understand spatial relationships. You can walk through your design and spot problems like a door that opens into a table. One thing that annoyed me: you can’t export high-res images without upgrading to Plus ($5/month). The free export is 640×480, which is fine for personal use but looks rough in a presentation.
What I liked:
- Wall drawing is fast and intuitive – click, drag, done
- Furniture library is massive even on free plan
- Automatic room area calculation
- Works in any browser, no installation
What fell short:
- Only 1 project on free plan (delete and recreate to work around this)
- Free export resolution is low
- No measurement overlay in 3D view
2. Planner 5D – Best for Interior Design Combined with Floor Plans
Planner 5D blurs the line between floor plan tool and interior design app. You start with walls and dimensions, then go deep into materials, colors, textures. I spent way too long picking kitchen tile patterns when I should have been measuring doorways.
The free version is more generous than Floorplanner – unlimited projects, no time limit. The catch is the furniture catalog. Free users get maybe 30% of the available items. Premium unlocks the full library plus HD 3D renders. But honestly, the free selection covers the basics: beds, sofas, tables, kitchen cabinets, bathroom stuff.
I found the wall-drawing slightly less precise than Floorplanner. Snapping works fine for straight walls, but angled walls (my apartment has a weird 135-degree corner) required manual angle input. The dimension tool sometimes jumps between metric and imperial if you’re not careful with your settings.
Available on iOS and Android too. The mobile apps are surprisingly capable – I actually prefer using Planner 5D on iPad for the touch-based wall drawing.
What I liked:
- Unlimited projects on free tier
- Deep interior design features (materials, textures, lighting)
- Cross-platform with cloud sync
- Community gallery for inspiration
What fell short:
- Catalog feels limited without premium
- HD renders require paid plan ($7/month)
- Angled walls are fiddly
3. Sweet Home 3D – Best Free Desktop Option (Open Source)
If you want something that’s genuinely, completely, no-strings-attached free, Sweet Home 3D is it. Open source under GPL, available on Windows, macOS, Linux, and even as a Java web app. No accounts, no trials, no “upgrade to unlock” popups. Everything is free forever.
The trade-off? It looks like it was designed in 2009. Because it was. The interface is functional but dated – toolbar icons are small, the property panels feel cramped, and there’s no modern dark mode or fancy animations. But here’s the thing: it’s more precise than most online tools. You get exact wall thickness control, elevation views, and the ability to import SVG or DXF files from professional CAD software.
I recreated my apartment in Sweet Home 3D in about 20 minutes. Longer than Floorplanner, mostly because the learning curve is steeper. But the result was more accurate – I could set wall thickness to exactly 12 cm (my actual walls), specify door swing radius, and place electrical outlets at precise heights.
The 3D view renders in real-time as you work. It’s not going to win any beauty contests, but for checking if furniture fits, it works perfectly. You can also create a virtual video walkthrough and export it as a video file.
What I liked:
- 100% free, no premium tier, no limits
- Precise measurements down to millimeters
- Imports DXF/SVG from CAD software
- Works offline, no account needed
- Plugin ecosystem with extra furniture packs
What fell short:
- Dated interface takes getting used to
- Steeper learning curve than web tools
- Web version runs slow on older machines (Java)
4. RoomSketcher – Best for Real Estate Listings
RoomSketcher positions itself as a tool for real estate agents, but the free plan works fine for personal use. You get one project and five 2D/3D snapshots. The floor plans look professional out of the box – clean lines, proper labeling, the kind of layout you’d see in an apartment listing.
Drawing walls is straightforward. Click to start a wall, click again to end it, and RoomSketcher automatically calculates room dimensions. The “intelligent walls” feature connects rooms automatically when walls touch, which saves time compared to tools where you manually connect every wall segment.
The free plan’s biggest limitation is exports. You can take 5 snapshots total (2D or 3D), and after that you need VIP ($49/year) for more. If you only need a single floor plan with a couple of views, the free tier covers you. For ongoing use, you’ll hit that wall fast.
What I liked:
- Professional-looking output with minimal effort
- Intelligent wall connections save time
- Clean 2D plans with area labels
What fell short:
- 5-snapshot limit is tight
- VIP pricing is steep for casual use ($49/year)
- Furniture selection on free plan is basic
5. Homestyler – Best for Photorealistic Renders
Homestyler started as an Autodesk project and it shows in the rendering quality. The free plan gives you 3 designs and 1 photorealistic render per day. Those renders look genuinely impressive – proper lighting, material reflections, shadows. I’ve seen people confuse Homestyler renders with actual photos.
Floor plan creation is solid. You draw walls with click-drag, add doors and windows from a catalog, then furnish the space. Homestyler has partnerships with real furniture brands (IKEA catalog was there last time I checked), so you can place actual products in your layout and see how they’d look.
The 3D walkthrough mode runs in your browser and feels smooth. You can adjust lighting (time of day, artificial lights) and see how sunlight falls through windows at different hours. That’s a feature I haven’t found in any other free tool.
The downside is speed. Homestyler loads slower than simpler tools, and generating a photorealistic render takes 2-5 minutes depending on scene complexity. If you just need a quick 2D plan with dimensions, this is overkill.
What I liked:
- Render quality is on another level for a free tool
- Real furniture brand catalogs
- Sunlight simulation by time of day
- Community designs you can clone and modify
What fell short:
- 3 design limit on free plan
- Only 1 render per day without paying
- Heavy on browser resources, needs decent hardware
6. SmartDraw – Best for Technical and Office Layouts
SmartDraw isn’t free in the traditional sense – it’s a 7-day trial, then $10/month. I’m including it because the trial is fully functional with no watermarks, and 7 days is enough to create and export a floor plan if you know your dimensions going in.
Where SmartDraw excels is technical floor plans. Office layouts with cubicle arrangements, warehouse plans with rack positions, restaurant seating charts. It has templates specifically for commercial spaces that the other tools on this list don’t cover well.
The interface is template-driven. You pick a floor plan template, then customize it. Wall drawing uses a grid system rather than freeform, which makes straight walls easy but curved or angled walls harder. For rectangular rooms (which covers 90% of office spaces), it’s fast.
No 3D view, which is a dealbreaker for some people. SmartDraw stays in 2D, focusing on accurate dimensions, labels, and annotations. The export options are excellent though – PDF, PNG, SVG, Visio format, and direct integration with Google Workspace and Microsoft Office.
What I liked:
- Commercial space templates (offices, restaurants, warehouses)
- Export to SVG, Visio, PDF
- Integration with Google Workspace and MS Office
- Clean, professional-looking output
What fell short:
- Not truly free (7-day trial only)
- No 3D visualization
- Grid-based drawing feels rigid for residential plans
7. MagicPlan – Best for Scanning Rooms with Your Phone
MagicPlan takes a completely different approach. Instead of drawing walls manually, you point your phone’s camera at a room and it builds the floor plan using AR (augmented reality). Walk to each corner, tap the screen, and MagicPlan constructs the walls automatically.
I tested this in my living room and the results were… mixed. The wall lengths were within 5-10 cm of my tape measure readings, which is fine for furniture planning but not for construction. The free plan gives you 2 projects with watermarked PDF exports.
Where MagicPlan gets interesting is the object recognition. It can identify doors, windows, and some fixtures automatically during the scan. Not perfectly – it missed my narrow bathroom window – but for a quick room survey, walking around with your phone beats spending 20 minutes drawing walls in a browser.
Available on iOS and Android. The AR scanning works better on newer phones with LiDAR sensors (iPhone 12 Pro and later). Older phones use basic camera-based measurement which is less accurate.
What I liked:
- AR scanning is genuinely faster than manual drawing
- Automatic door and window detection
- Great for quick surveys of existing spaces
What fell short:
- Accuracy varies by phone hardware (5-10 cm margin)
- Only 2 free projects
- Watermarks on free exports
- Useless for planning spaces that don’t exist yet
8. Diagrams.net (Draw.io) – Best Completely Free Option for Simple Plans
Diagrams.net (formerly Draw.io) is a general-purpose diagramming tool, not a dedicated floor planner. But it has a floor plan shape library, and since it’s 100% free with no limits, it deserves a spot here.
The approach is different from dedicated tools. You drag pre-made shapes (walls, doors, furniture symbols) onto a grid canvas and arrange them. There’s no automatic wall calculation, no 3D view, no furniture catalog with realistic renders. Think of it as drawing a floor plan the way you’d draw one on graph paper, except digital.
For quick schematic plans – “kitchen is here, bedroom is there, bathroom goes in this corner” – Diagrams.net is perfectly fine. I use it when I need a floor plan for a document or email, not when I’m actually planning furniture placement. The export is unlimited: PNG, SVG, PDF, XML, whatever you need.
Completely browser-based, saves to Google Drive, OneDrive, or locally. No account required if you save locally.
What I liked:
- Absolutely free, no limits, no account needed
- Export to any format
- Integrates with Google Drive and OneDrive
- Lightweight, loads instantly
What fell short:
- Not a real floor plan tool – more of a workaround
- No 3D view, no realistic furniture
- Manual everything – no smart walls or auto-dimensions
How to Create a Floor Plan: Step by Step
Regardless of which tool you pick, the process is similar. Here’s how I approach it:
Step 1: Measure your space. Use a tape measure or laser measurer. Write down every wall length, door width, and window position. Don’t skip this – guessing measurements leads to furniture that doesn’t fit.
Step 2: Draw exterior walls first. Start with the overall shape of your space. Most tools let you input exact dimensions, so punch in your measured numbers. Get the outline right before adding interior walls.
Step 3: Add interior walls, doors, and windows. Interior walls divide the space into rooms. Place doors with correct swing direction (90-degree arc shows where the door opens). Position windows at their actual locations on the wall.
Step 4: Place fixed elements. Kitchen cabinets, bathroom fixtures, built-in wardrobes – anything that can’t move. These constrain where everything else goes.
Step 5: Add furniture. Now the fun part. Drop in your bed, sofa, dining table, desk. Leave walking paths (minimum 60 cm for comfortable movement, 90 cm for main paths). Check that doors can open without hitting furniture.
Step 6: Review in 3D (if available). Switch to 3D view and walk through your layout. Things that look fine in 2D sometimes feel cramped in 3D. Pay attention to sightlines and how rooms connect.

Which Tool Should You Actually Use?
Depends on what you’re trying to do. Here’s my honest take after testing all of them:
Rearranging furniture in an existing apartment: Floorplanner. Fast, intuitive, good enough 3D to check if things fit. The 1-project limit doesn’t matter if you only have one home.
Interior design with material/color planning: Planner 5D or Homestyler. Both go beyond floor plans into full interior visualization. Homestyler wins on render quality, Planner 5D wins on project limits.
Maximum precision without paying: Sweet Home 3D. The only tool here that lets you control wall thickness, import CAD files, and has zero restrictions. Worth the learning curve if accuracy matters.
Real estate listing or presentation: RoomSketcher. The output looks professional enough to use in a listing without modification.
Scanning an existing room fast: MagicPlan. Nothing else comes close for speed when you just need to capture an existing space.
Simple schematic without fuss: Diagrams.net. Free, instant, no account. Not pretty, but gets the job done. For other diagramming needs, you might also want to look at dedicated flowchart and diagram tools.

FAQ
Can I create a floor plan online without downloading software?
Yes. Floorplanner, Planner 5D, Homestyler, RoomSketcher, SmartDraw, and Diagrams.net all run entirely in your browser. No downloads needed. Sweet Home 3D also has a web version (runs via Java), though the desktop version is more stable. MagicPlan requires a mobile app download.
What is the most accurate free floor plan tool?
Sweet Home 3D offers the highest precision. You can set exact wall thickness, specify dimensions down to millimeters, and import professional CAD files (DXF/SVG). For phone-based scanning, MagicPlan with a LiDAR-equipped phone (iPhone 12 Pro or newer) gets within 2-3 cm of actual measurements.
Is Floorplanner really free?
The basic plan is free with 1 project and unlimited rooms. You can draw walls, add furniture, and view in 3D without paying. The Plus plan ($5/month) adds more projects and high-resolution exports. The free export is 640×480 pixels, which works for screen viewing but not for printing.
Can I use these tools to create floor plans for construction?
For actual construction, most of these tools lack the technical detail a contractor needs (load-bearing wall specs, electrical routing, plumbing plans). Sweet Home 3D comes closest since it supports exact dimensions and CAD import. For professional construction drawings, you’d typically need AutoCAD, SketchUp Pro, or a licensed architect’s software.
What’s the fastest way to create a floor plan of my current home?
MagicPlan’s AR scanning. Walk around your room, tap at each corner, and the app builds the plan automatically. Takes about 2 minutes per room on a newer phone. The alternative is measuring everything manually and drawing it in Floorplanner, which takes 15-30 minutes for a typical apartment.
