Free Floor Plan Software and Apps Compared (2026)

The best free floor plan software depends on what you need at the end. For a full desktop program with no account, Sweet Home 3D is free and open source. For a quick plan in the browser, Floorplanner, Planner 5D, Homestyler and FloorGen all have free tiers, with different limits on projects, exports and watermarks. RoomSketcher is free to try, with most finished output paid, and SketchUp Free is a general 3D modeler for non-commercial use rather than a floor plan tool.

We make FloorGen, so read our entry with that in mind. For the others, we checked each vendor's own pricing and help pages in October 2026 and say where those pages are unclear or contradict each other. Free tiers change often; check the vendor's page before you commit a project to it.

What to look for in free floor plan software

• Export. Can you get your plan out at a usable resolution, without a watermark, and to scale? This is where free tiers differ most.
• Project limits. Some free tiers cap the number of projects; others do not.
• Account. Some tools work immediately; others need sign-up first.
• Units and dimensions. Feet and inches, typed lengths and dimension strings matter if the plan goes to a contractor or a permit office.
• Commercial use. If you are a contractor, agent or designer using the plan for paid work, check the license. Several free tiers are personal-use only.

The comparison at a glance

Sweet Home 3D

Sweet Home 3D is an open-source interior design program for Windows, macOS and Linux, with an online version that runs in the browser. Its FAQ says it can be used free of charge for personal or commercial purposes, and the desktop version needs no account. You draw walls and rooms in 2D and see the result in 3D as you go. The free download includes a smaller built-in furniture library than the paid Mac App Store and Microsoft Store editions, and extra libraries can be imported. It is the strongest choice if you want a full program that runs offline with no strings attached; the interface is more traditional than the newer web tools.

Floorplanner

Floorplanner is a browser-based planner with a quick drag-and-drop workflow. Its free Basic plan allows 5 projects. Its pricing page lists free exports at standard definition, 960 × 540 for 2D and 3D, with a Floorplanner watermark and a cooldown between exports; higher resolutions are unlocked per project with paid credits. The pricing page and a help article disagree on how many floors a free project can have. A good fit for trying layouts and sharing images; less so if you need a large, clean export for free.

RoomSketcher

RoomSketcher is aimed at homeowners, agents and designers who want polished 2D and 3D floor plans. You can create a free account without a credit card, draw a plan and view it in 3D. On the free plan, 3D snapshots are low resolution with a watermark, and RoomSketcher says generating 2D and 3D floor plans for printing or download requires a purchase. Its pages are inconsistent on the free project count, stating "up to two projects" on one page and a larger archive on another. Paid plans add print-to-scale and branding. Worth a look if you want presentation-quality plans and expect to pay for the final output.

Planner 5D

Planner 5D runs in the browser, on phones and tablets and on Windows. Its pricing page says the free plan lets you create and share unlimited projects with access to half of the furniture catalog, in 2D and 3D, and its help center lists PDF export as available on the free plan. Its terms (last updated in 2021) say renders carry a watermark for personal use and that commercial use requires a commercial account. Paid plans unlock the full catalog, and the Professional plan adds watermark-free 4K renders and CAD export. It is one of the few here that is comfortable on a phone.

SketchUp Free

SketchUp Free is the browser version of Trimble's 3D modeler. It is powerful and can model anything, including a house, but it is not a floor plan tool: there are no walls, doors or room areas as objects, so you build them from lines and faces. Trimble's help page states SketchUp Free is not for commercial use and includes 10 GB of cloud storage. Its help and marketing pages list different import and export options, so check what you need before you start. Choose it if you want to learn 3D modeling or need a shape no floor plan tool will draw.

Homestyler

Homestyler is a browser-based home design tool with an emphasis on decorated, photorealistic renders. Its pricing page describes the free Basic plan as unlimited projects and unlimited 1K renders, with 4K renders bought individually or included in paid plans. Watermark removal is listed as a paid-plan feature. A good fit if your goal is decorating ideas and pictures rather than a dimensioned plan.

FloorGen

FloorGen is the browser-based floor plan editor we build. It is free and works without an account: projects are saved in your browser, and signing in moves them to the cloud. It is built around dimensioned plans in feet and inches as much as pictures:

• Walls with real thicknesses, typed lengths such as 11' 6", and automatic dimension strings you can switch between centreline, inside and outside.
• Room areas, door and window schedules with D1 and W1 tags, and an IRC (US) code profile that flags undersized rooms, bedrooms without an escape window and steep stairs.
• Tracing from a photo, scan or PDF, with a two-point scale and an option to detect walls from the image.
• A print set PDF with a sheet per floor at a real scale, on Letter, Tabloid, ARCH C or ARCH D among others, plus PNG, SVG and DXF exports for CAD.
• A 3D view with a walk mode and GLB export, and US templates such as ranches, a two-story, ADUs and single rooms.

The trade-offs: it runs only in a browser, its 3D view is for checking a design rather than photorealistic rendering, and fixtures and furniture are drawn as top views rather than the line symbols some drafters prefer.

The ADU above is 40 × 20 ft outside, 800 ft², with 700.5 ft² of net room area: a living room of 175.4 ft², a dining area of 112.7 ft², a kitchen of 88.5 ft², bedrooms of 115.7 and 93.2 ft², and a 45.4 ft² bath. It is a typical size for a backyard unit; 800 sq ft ADU floor plans looks at layouts in detail.

Which one should you use?

Whichever you choose, the plan is only as good as the measurements behind it; how to measure a room for a floor plan is the place to start, and how to draw a floor plan covers the rest.
