Any floor plan app looks good enough until a builder, a kitchen fitter or a client has to work from what you've drawn. For one room or one home project, a free browser planner is plenty. Renovators juggling several jobs need a paid planner without project caps. Builders who sell with pictures need trade software that renders.
Drawing a floor plan on screen used to mean graph paper or architect software. Now there's a wide middle ground: browser planners that turn a sketch into a 3D view, apps you buy once and keep, and design suites made for people who build houses for a living. This guide sorts out which of those you need, what the category costs, and how to test a tool in an hour with your own home. The eight tools follow.
Three jobs that all get called floor planning
The first job is working out a room. Will the sofa fit, where does the desk go, is there space for an island? You need walls, doors, windows and furniture at the right size, and a 3D view helps you feel the space. Almost anything on this page does that.
The second job is planning a renovation. Now the plan has to be accurate enough that a builder or kitchen fitter can quote from it, and you'll often want two or three versions side by side: the room as it stands, and the options you're weighing up. Project limits on free plans start to matter here, and so does exporting a clean, measured drawing.
The third job is selling or designing for clients. A builder showing a homeowner what an extension will look like, or a designer pitching a layout, needs renderings good enough to win the work, and tools that keep up when there are several jobs on the go. That's a different category of software, priced like one.
Be honest about which job you have. Most people buy for the third and only ever do the first.
Browser, installed app or trade suite
Browser planners run in a tab, save to the cloud and are the quickest way to get from a blank screen to a 3D room. Several now bundle AI design tools. Their free plans tend to be capped by the number of plans, projects or exports, which is fine for a single home and frustrating for a renovator.
Installed apps run on your computer, phone or tablet. They suit people who'd rather own the software than rent it, and some sell a licence you pay for once. Check how they handle more than one device, because a Mac version and an iPad version can be separate purchases.
Trade suites are built for builders, remodelers and residential designers. They produce interior and exterior renderings and fuller drawings, and they're priced as business tools. For a home owner they're overkill. For someone who designs homes every week, they're the point.
How the money works
The range is wider than in most software categories. At one end there's free desktop software and free browser plans that cover a first plan or a few projects. In the middle you'll find credits bought per export without a subscription, lifetime licences for well under a couple of hundred dollars, and browser subscriptions of a few hundred a year at most. At the top, professional design software runs to nearly two thousand dollars a year. If you're drawing your own home, you shouldn't need to spend more than the middle of that range, and many people never leave the free end.
AI has moved into the planners
A few of the browser planners now sit next to AI interior design tools: you describe a style or a room, and the software suggests layouts or furnishings. It's a fun way to get ideas. Two things to know before you get attached to it. In at least one of these planners the AI features run on credits and the free plan includes none, so you can draw in 3D there but not touch the AI at all. And an AI-suggested layout is a starting point, not a measured plan, so it still needs checking against the real room before anyone orders a kitchen.
An hour with your own floor plan
Measure one room carefully first: every wall, the position and width of each door and window, the ceiling height, and where radiators and sockets sit. Then draw that room in two tools, ideally one browser planner and one installed app. Time how long it takes to get the walls right, add a door and window, and drop in your actual sofa or bed at its real size.
Now try the thing you'll need later. Export the plan as an image or PDF and look at whether the measurements are readable. Switch to 3D and see if it helps you decide anything. Copy the plan and make one change, such as moving a wall, to see how easy versions are. Whichever tool got you through all of that with the least swearing is the one to keep, regardless of how many features the other one lists.

Which one should you open first?
For a single room or one home project, open a free browser planner or a free desktop app and stay there until it stops you. Spending more won't make a kitchen plan more accurate; measuring well will. Sweet Home 3D is a good example of that type: plan, furniture, 3D view, done.
If you're renovating more than one property, the caps on free plans are what will bite, so pick a browser planner whose paid plan lifts the project limit, or an installed app you buy once and keep. If you work across a phone, a tablet and a laptop, check how the app handles each device before you pay.
If plans are part of how you win work, go to the trade suites. Software that produces interior and exterior renderings, such as Cedreo, is aimed at builders selling a project, while full residential design software suits a firm that designs homes every week. For room styling rather than walls, see these interior design apps, and if you'd like AI to rough out a first draft there's a guide to drawing a floor plan with AI for free.

Frequently asked questions
What's the difference between a 2D plan and a 3D model?
A 2D plan is the bird's-eye drawing with walls, doors and measurements, the thing a builder works from. A 3D model lifts that plan into a view you can move around, which is better for judging space and furniture. Most tools here draw the 2D plan first and build the 3D view from it.
Will a builder work from a plan I draw myself?
Usually as a brief, not as a construction drawing. A clear, measured plan helps a builder or kitchen fitter understand what you want and quote faster, but they'll still measure on site, and structural work needs drawings from someone qualified to produce them.
