Planner 5D is the best all-around free option for most people in the United States in 2026. It combines 2D plans, 3D furnishing, web and mobile access, and unlimited free projects. Its free catalog is limited, however, so it is not the best choice for everyone. Floorplanner is better for measured layouts, Homestyler for polished 3D scenes, IKEA Kreativ for trying IKEA products in your own room, and a photo-based AI tool for quick style ideas.
“Free” can mean a free download, a limited free tier, or a tool that is genuinely usable for one specific job. The ranking below separates those meanings and identifies the first important paywall, platform limits, and accuracy risks. Prices and features can vary by country, device, app store, and account; the descriptions here are for U.S. readers and the August 2026 information available from the linked providers.
What an interior decorating app actually does
These tools solve different problems, so no single score is fair across all of them.
- Style inspiration: colors, finishes, themes, and mood boards.
- Photo restyling: generating alternative looks from a room image.
- Furniture visualization: placing catalog items in a room.
- Room layout: arranging furniture inside measured dimensions.
- Floor planning: drawing walls, doors, windows, and multiple levels.
- 3D modeling: creating custom rooms, built-ins, or furniture.
- Shopping support: connecting a design to real products and prices.
- Professional documentation: exporting plans for a contractor or client.
A beautiful AI image may help with the first two tasks while being unsuitable for the last five. Use the category that matches your decision.

1. Planner 5D — best overall free option
Planner 5D’s free plan allows unlimited projects across web and mobile, making it the most balanced starting point for a beginner planning an entire home. You can sketch a room in 2D, switch to 3D, place furniture, and continue on another device.
What is free
- Unlimited projects.
- Web and mobile workflows.
- Core 2D and 3D room planning.
Where payment begins
The free catalog contains only a portion of the library (the pricing page describes about half). Floor-plan uploads, realistic renders, advanced items, budget tools, and other capabilities may require Premium. The U.S. App Store listing also describes limited catalog access; website and app-store prices can differ.
Choose it when: you want one general-purpose tool and can work with a curated catalog. Skip it when: you need a specific retailer’s exact product or construction-ready drawings.
2. Homestyler — best for realistic 3D decorating
Homestyler’s Basic plan is a cloud 3D planner with unlimited 1K renders and access to more than 100,000 free 3D models and materials. Its room-design app is aimed at users who care about how a finished scene looks.
Strengths and limits
- Strong visual presentation for furniture, finishes, and lighting.
- Large generic model library for experimenting.
- Higher-resolution rendering, AI features, custom uploads, advanced modeling, and watermark removal can be paid or credit-based.
A polished render can appear more dimensionally exact than it is. Treat model dimensions as planning inputs, not proof that a real product will fit.
3. IKEA Kreativ — best for visualizing IKEA furniture in a real room
IKEA Kreativ lets you photograph or upload a room, remove existing furniture, and add IKEA products. IKEA says the complete U.S. room-design experience is free.
Scanning and platform differences
The mobile app can capture a room; full-room 3D scanning requires a LiDAR-enabled device. Non-LiDAR devices use photographic wide-angle scanning. On the web, you can build a room manually and enter dimensions. See IKEA’s platform comparison and scanning instructions.
Important boundaries
The catalog is primarily IKEA, and the tool does not cover every category: IKEA identifies textiles, ceiling-mounted items, and full kitchen design as limitations or separate planner use cases. Use the IKEA planning ecosystem for kitchens, bathrooms, storage, and other specialist projects.
Free tools Windows power users keep installed
One-click scans. No signup required.
4. Floorplanner — best for free layout planning
Floorplanner is free for casual use and supports up to five free projects. The free projects can contain up to three floors and three designs, with SD-quality exports and watermarks. One-time credits unlock higher-resolution exports, extra functionality, and 3D tours; the Basic plan explains the free workflow.
It is less glamorous than an AI makeover, but measured walls, openings, and circulation paths make it the better choice for a small room, a shared layout, or a plan you need to discuss with a contractor.
5. Roomstyler — best for quick browser decorating
Roomstyler is a simple, furniture-oriented browser tool for trying colors, arrangements, and room styles without learning professional CAD. Confirm the current catalog, project quota, and export rules before relying on it for a larger project; those limits change more often than the core interface.
Choose it for: fast experimentation. Skip it for: measured construction plans or guaranteed, purchasable products.

Pick the symptom - the matching free tool is one click away.
6. HomeByMe — best for beginner-friendly room visualization
HomeByMe combines 2D planning with 3D furnishing and is approachable for individual rooms or a small home. The number of free projects, 3D images, image resolution, and catalog features can change, so check the current U.S. account terms before starting a project you must export.
7. RoomSketcher — best for measured floor plans
RoomSketcher is oriented toward documenting an existing space and viewing it in 3D. Verify whether your account includes measurements, snapshots, downloads, and the number of editable projects; these functions may be separated between free and paid plans.
8. SketchUp Free — best for advanced DIY 3D modeling
SketchUp Free is a browser-based modeler for custom furniture, built-ins, unusual room shapes, and renovation concepts. It offers far more geometric freedom than a guided decorating app, but you must build or find models yourself and learn the modeling tools. Product dimensions and model quality vary, so verify every critical measurement.

Tools such as RoomGPT, Remodel AI, DecorMatters, ReimagineHome, or a comparable current service can turn a room photo into several style concepts. Treat this as a category, not a permanent winner: free generations, watermarks, account requirements, storage, and platform availability change quickly.

Check before uploading
- How many free generations are included and whether they consume credits.
- Whether the output is watermarked or requires a subscription to download.
- Whether doors, windows, walls, and room proportions stay fixed.
- Whether displayed products are real listings or fictional imagery.
- How the service stores photos and uses them for training.
AI may move a window, change a ceiling height, or invent furniture dimensions. Compare every concept with the original photograph and never use it as a measured plan.
How to choose in under a minute
- Want instant ideas from a photo? Use a photo-based AI decorator, after checking credits and privacy.
- Need exact room dimensions and circulation? Start with Floorplanner or RoomSketcher.
- Want one beginner tool for a whole home? Choose Planner 5D.
- Want polished 3D scenes? Choose Homestyler.
- Want to test IKEA products before buying? Choose IKEA Kreativ.
- Need custom geometry or built-ins? Choose SketchUp Free.
Accuracy, privacy, and failure checks
Verify measurements in the room
- Wall lengths and ceiling height.
- Door swings, window clearances, and walkways.
- Actual furniture dimensions, appliance clearances, and delivery paths.
- Electrical, plumbing, structural, and code requirements.
Consumer decorating software helps communicate an idea; it does not replace field measurements, an interior designer, architect, engineer, or contractor for technical work.
When a scan or render fails
Improve lighting, remove visual obstructions, close other apps, and rescan. IKEA specifically recommends closing other apps and retrying if scanning is slow or freezes. If an export is low resolution, keep the editable project and use a screenshot for personal reference rather than presenting it as professional documentation.
Protect room photos
Photo-based services may upload images to remote servers. Do not include family photos, addresses, valuables, or other identifying details until you understand the provider’s current retention and training policy. Web and mobile versions may also expose different features, and many tools require an internet connection.
If you need more than the free tier
- Planner 5D Premium: adds the full catalog, floor-plan uploads, richer renders, model import, and budget tools; see official pricing.
- Homestyler paid plans: target higher-resolution output, watermark removal, custom uploads, advanced modeling, and additional AI credits; see official pricing.
- Floorplanner credits: let you upgrade a particular export without automatically taking a subscription; see credit options.
- IKEA’s design ecosystem: connects visualization to IKEA products and specialist planners. IKEA’s U.S. site also lists virtual interior-design appointments at $149 per room; confirm current terms before booking.
Subscriptions, taxes, regional prices, promotional rates, and app-store billing can change. Review cancellation and auto-renewal language before paying.
