The options below cover different budgets and needs, so read the best for line first and shortlist two or three that match your situation.

If your workflow hits that limit every week, a different option on this list will serve you better, while a reader who rarely hits it may never notice the gap. Our take: Planner 5D is worth a trial when room layouts in 2D and 3D is your main need, and the vendor site shows it starts free with a free plan is available.

How we picked these
We started from the main keyword and the related searches readers use, then checked official feature pages, pricing pages, app store listings, privacy pages and public reviews for each candidate. We kept only products that exist and work today, that truly fit best interior design apps free, and whose official homepage loads. We mixed well known leaders with smaller options, and we favoured products with clear pricing, a trial or free plan, and honest limits we could state plainly. We did not claim hands-on testing that did not happen. Instead, we compared what vendors publish, what reviewers report, and where each product fits best, so readers can see both strengths and catches before they spend money or time on a trial.
How to choose a free interior design app
Start with accurate room measurements, because a beautiful plan built on wrong dimensions leads to furniture that does not fit. Measure walls, doors, windows and outlets, then test the app with that real room before designing a whole home. Check whether the catalogue includes the brands and sizes you actually buy, whether 3D views and renders are included free, and how many projects you can save. Planner 5D and HomeByMe suit visual planning, SketchUp Free suits custom shapes, and IKEA Planner suits IKEA only rooms. Start with a shortlist of three, not ten, and give each one the same test task. Note where you get stuck, how long setup takes, and whether support answers clearly, because those small frictions grow with daily use. Keep notes from each trial in one place, so the final choice rests on evidence from your own workflow, not on a feature list alone.
Frequently asked questions
What is the best free interior design software?
Planner 5D is the easiest all round free pick, HomeByMe suits realistic renders, and SketchUp Free suits custom 3D work. Roomstyler is a good browser option when you do not want to install an app.
Can I design a room for free?
Yes, Planner 5D, Roomstyler, HomeByMe, SketchUp Free, IKEA Planner and Sweet Home 3D all offer free tiers. Paid plans usually add catalogue items, renders or project limits.
Are free interior design apps accurate?
They are accurate when your measurements are accurate, since the app only draws what you enter. Measure twice, check door swings and outlet positions, and confirm furniture dimensions before ordering.
Which app is best for kitchen design?
IKEA Home Planner suits IKEA kitchens, while Planner 5D and HomeByMe suit general kitchen layouts with varied brands. For a full remodel, confirm cabinet and appliance dimensions with the supplier.
Do I need 3D rendering?
3D views help you judge light, scale and flow better than a flat plan, especially for colour and furniture choices. A simple 3D view is usually enough, while photorealistic renders matter more for client presentations.
