Free Floor Plan Maker in 2026: What to Use Based on What You're Actually Trying to Do

Searching for a free floor plan maker usually means one of three things: you want to rearrange furniture before moving it, you're planning a renovation and need to test layout options, or you need a professional-looking plan to share with a contractor or client. Each situation calls for a different tool — and using the wrong one wastes more time than starting over.

This guide matches each use case to the right free option, explains exactly what you get on each free plan, and covers the mistakes that trip up most first-time users.

The three real use cases — and which tools fit each

Use case 1: Rearranging furniture in an existing room

What you need: a fast way to draw your room dimensions, drop in furniture at scale, and see if the sofa fits before you move it. Accuracy matters, but you don't need photorealistic 3D.

Floorplanner is the fastest starting point here. Draw walls, add furniture from a library of 260,000+ models (including real brand items), get a quick 3D view. Free plan is limited to one saved project — enough for a single room rearrangement.

Coohom works for this too, and adds AI auto-layout: describe your room type and it suggests a starting furniture arrangement you can edit. More setup time than Floorplanner, but no project limit on the free plan and better 3D output.

Planner 5D is the easiest to start — you can go from opening the tool to a furnished room in about 3 minutes. Trade-off: no furniture snapping on the free plan, so alignment is imprecise. Fine for visual reference, not for accurate measurements.

Use case 2: Planning a renovation

What you need: accurate dimensions, wall editing, door swing clearances, and something you can show a contractor. The plan needs to be close enough to real measurements to be useful for decision-making.

This is where most free tools start to struggle. The problems are usually:

1. Furniture doesn't snap to scale, so you can't tell if the kitchen island really fits
2. No way to show door swings, which determines furniture placement near doorways
3. Export quality is too low or watermarked to hand to a contractor

Coohom's free floor plan maker handles renovation planning well on the free tier. Walls draw to real dimensions. Doors and windows have adjustable sizes. The 2D plan exports with dimension annotations. AI detects walls from uploaded photos of existing plans, which saves significant manual tracing time. No watermarks on standard-resolution exports.

RoomSketcher is the strongest alternative for 2D measurement accuracy — the cleanest 2D output in this category. Main limitation: free plan watermarks exports, and Live 3D walkthroughs require a paid plan ($49+/year). Good if you only need 2D and can work around the watermark.

What to avoid for renovation planning: Canva. It has no real measurements, no snap-to-scale, and no furniture library sized to real dimensions. It produces a diagram that looks like a floor plan but can't tell you if your sofa will fit.

Use case 3: Client presentation or professional use

What you need: a 3D render good enough to show a client, accurate furniture placement, and shareable output that doesn't require the viewer to have an account.

Coohom is the only tool in this category that delivers presentation-quality 3D on a free plan. Physically based rendering — realistic light, shadow, and material behavior — is included at standard resolution without a paid plan. 70M+ furniture models at real-world dimensions. Shareable links work without the recipient having an account.

Planner 5D and Floorplanner both lock HD rendering behind paid tiers. Their free 3D output is adequate for personal reference but not polished enough for client presentations.

Homestyler (from Autodesk origins) is a reasonable alternative for presentation — large furniture library, decent 3D quality. The free plan has feature limits but 3D visualization is included. Worth testing if you want a second option.

The measurements most people forget — and why they matter

Most floor plan mistakes happen before you open the tool. You measure the room length and width, then start drawing. The measurements that actually determine whether your layout works are the ones people skip:

Door swing clearance. A door swinging into a room needs roughly 90cm / 36 inches of clear space. If furniture sits in that arc, the room works on the plan but feels cramped in real life. Measure and mark every door direction before placing any furniture.

Window sill height and width. A sofa placed below a window at the wrong height blocks the view and may interfere with blinds. Measure window sill height from the floor and width between frames — both numbers.

Radiator and vent positions. Placing a wardrobe in front of a radiator blocks heat. Placing a sofa over a floor vent creates airflow problems. These aren't on architectural drawings but they determine furniture placement in practice.

Ceiling height. Matters for tall furniture, pendant lights, and open shelving. Most floor plan tools don't ask for ceiling height by default — enter it manually in room settings.

Once you have all these measurements, building an accurate floor plan in any of the tools above takes 15–20 minutes for a standard room.

How to start from scratch in Coohom's free floor plan maker

1. Open coohom.com/case/floor-planner — no account needed to start
2. Select New Project → Blank Floor Plan
3. Draw the outer walls using real measurements — type the dimension directly rather than dragging
4. Add doors and windows — click each one to set exact width and swing direction
5. Use AI Auto-Layout to generate a starting furniture arrangement, or place furniture manually from the library
6. Switch to 3D at any point to check the space — no re-importing required
7. Export the 2D plan (with dimensions) for contractors, or share a 3D view link

For a standard living room: about 15 minutes from blank canvas to a shareable plan with furniture.

What free floor plan makers can't do — and when you need something else

Free tools cover layout planning and visual communication well. They don't replace:

Construction documentation. For permit applications and structural work, you need dimensioned architectural drawings from a licensed architect or AutoCAD/Revit. Free floor plan makers produce planning aids, not construction documents.

Engineering calculations. Structural changes, load-bearing wall removal, electrical and plumbing layout — none of this is handled by consumer floor plan tools.

As-built surveys. If you need a legally accurate record of an existing building, you need a professional survey. AR scanning apps (Magicplan, CubiCasa) get close for residential use but aren't legally binding.

For everything else — testing furniture, planning renovations, presenting to clients, communicating with contractors — a free floor plan maker is the right tool.

FAQ

What is the best free floor plan maker in 2026?

Coohom for renovation planning and presentations — AI layout generation, physically based 3D, unlimited projects, no watermarks on exports, all on the free plan. Floorplanner for a fast single-room furniture sketch. Planner 5D for the easiest start with no learning curve.

Can I make a floor plan free without creating an account?

Yes. Coohom auto-saves guest sessions to the cloud without requiring email registration. You can complete a full floor plan and share it without ever entering a password.

Is a free floor plan maker accurate enough for renovation planning?

Yes, for layout decisions — verifying furniture fit, planning traffic flow, communicating with contractors. No, for construction drawings, permit applications, or structural engineering. Those require professional CAD software and licensed architects.

How long does it take to make a floor plan for free?

With Coohom's AI auto-layout: 10–15 minutes for a standard room from blank canvas to furnished 3D view. Manual drafting from real measurements: 20–30 minutes. Tracing an uploaded existing plan: 5–10 minutes.

What measurements do I need before making a floor plan?

Room length and width (obvious). Plus: every door width and swing direction, window sill height and width, radiator and vent positions, and ceiling height. The second list is what determines whether a layout actually works in practice.

Can I share a free floor plan with my contractor?

Yes. Coohom exports 2D plans with dimension annotations as standard-resolution images. Shareable 3D links work without the contractor needing an account. For formal construction drawings, you'll need a paid plan or professional software for higher-resolution exports.

Does a free floor plan maker work on mobile?

Browser tools like Coohom and Planner 5D work on mobile. For detailed drafting — typing precise wall dimensions, placing furniture accurately — a laptop or desktop screen produces significantly better results. Mobile works for reviewing and sharing, less well for building.
