Most free kitchen planners fall into two camps: quick 2D tools that get you a dimensioned floor plan in minutes, and heavier 3D suites that look impressive but slow you down. If your goal is briefing a fitter accurately, a fast browser-based planner with snap-to-grid measurements beats a photorealistic room you can't share as a clean plan. Here's how the real options stack up.
| Planner | Sign-up needed | 2D floor plan | Live dimensions | Layout types | Export to share | Best for |
|---|---|---|---|---|---|---|
| Free Room Planner | No | Yes | Yes (10cm snap-to-grid) | Galley, L, U, island, single-wall | Clean PNG | Briefing a fitter fast |
| Retailer-branded 3D planners | Usually yes | Yes | Partial | All common layouts | Screenshot / saved project | Buying that retailer's units |
| General 3D design apps | Yes | Yes | Some show live measures | All common layouts | Image (often paywalled) | Picturing finishes in 3D |
| Diagram / drawing tools | Sometimes | Yes | Manual entry | Any (freehand) | Image / PDF | Rough concept sketches |
| Dimension reference sites | No | No (reference only) | N/A | Reference only | N/A | Looking up standard sizes |

For most homeowners, a free browser-based 2D planner is the best choice because it produces an accurate, dimensioned floor plan you can send to a fitter in minutes without a sign-up, download, or learning curve. Full 3D suites suit you only if you care more about seeing finishes than sharing measurements. Reference sites are useful alongside a planner, not instead of one.
The ranking below reflects what each type does well for the job that matters: turning your room into a plan a professional can build from.
The ranked shortlist
1. Free Room Planner — best for briefing a fitter quickly
Free Room Planner runs in any browser with no sign-up, no download, and no cost. Draw your walls, drop in units at standard depths, and every wall snaps to a 10cm grid so your measurements are accurate by default. As you move units, live measurements show the gap between facing elements in real time — so you can check aisle widths against the minimums as you go.
When the layout looks right, export a clean PNG and send it straight to your fitter or kitchen maker. They get a dimensioned floor plan, not a rough sketch. It covers galley, L-shape, U-shape, island, and single-wall layouts. The trade-off: it's 2D, so you won't see photorealistic finishes. For planning that fits and communicates clearly, that's rarely a loss.
2. Retailer-branded 3D planners — best if you're buying their units
Retailer planners let you build a layout from that specific brand's cabinet range and often show pricing as you go. That's genuinely useful if you've already chosen where to buy. The catch: they usually need an account, they lock you into one product catalogue, and exporting a plain dimensioned plan to hand a third-party fitter can be awkward.
3. General 3D design apps — best for picturing finishes
These produce impressive 3D views and suit you if seeing worktop colours and cabinet fronts matters more than getting a plan out the door. They come with a learning curve, most ask you to register, and the sharper export options often sit behind a paid tier. Slower to start, heavier to run.
4. Diagram and drawing tools — best for rough concepts
General drawing tools — including a Canva floor plan maker approach — work for a quick sketch. But you enter dimensions manually with no snap-to-grid, so accuracy depends entirely on you. Fine for a napkin-level idea, risky for anything a fitter will price.
5. Dimension reference sites — best for looking up standard sizes
Sites that catalogue kitchen dimensions and drawings are excellent references for standard cabinet sizes and clearances. They don't plan your room, though. Use them to confirm a number, then draw the layout in an actual planner.
When is each option the better choice?
Choose a free 2D browser planner when your priority is an accurate, shareable floor plan and you want it done today. Choose a retailer planner when you've committed to buying units from that store and want live pricing. Choose a 3D app when picturing finishes and materials is the point of the exercise. Choose a drawing tool for a rough first sketch. Choose a reference site to check a standard measurement — never as your only planning step.

What dimensions should any kitchen planner let you check?
A good planner should let you verify counter depths, aisle widths, and layout-specific clearances. The numbers below are the standards used by most fitters across the UK, US, and Europe — confirm exact specs with your supplier.
- Base cabinet depth: 60cm (24in) standard; 45cm (18in) for tight spaces.
- Finished counter height: around 91–95cm (36–37.5in).
- Wall cabinet depth: 30–35cm (12–14in), mounted 45–50cm above the worktop.
- Minimum single-cook aisle: 1.0m (40in). Below this, appliance doors won't open freely.
- Two-cook aisle: 1.2m (48in) so two people pass and work at once.
- Appliance door clearance: at least 1.0m (40in) of clear space in front of oven and dishwasher doors.
Layout-specific clearances at a glance
Each common layout has its own non-negotiable minimum — worth checking against the NKBA kitchen design guidelines and ADA minimum distances where they apply:
- Galley: corridor of 1.0m absolute minimum, 1.2m for two cooks. The gap runs between unit fronts, not walls.
- L-shape: at least 60cm of clear worktop each side of the corner unit to beat the dead-corner effect. Room from roughly 3.0m x 3.0m.
- U-shape: 1.2m minimum between parallel runs, 1.5m to feel comfortable. Put tall units on the back wall.
- Island: 1.0m clearance minimum on all sides, 1.2m where people work or appliance doors open. Functional island from 0.9m x 1.5m.
- Single-wall: run no longer than 3.6m, with 1.2–1.5m of clear floor in front.
The work triangle — linking the cooker, sink, and refrigerator — is a useful sense-check. Keep the total perimeter between 3.6m and 7.9m. But treat it as a guideline, not a rule; open-plan and multi-cook kitchens often work better as two overlapping zones.
How do you draw floor plans accurately in a free planner?
Accurate floor plans start with accurate measurements, then a tool that keeps them to scale. Here's the reliable four-step method in a free planner:
- Measure the room. Record length, width, and the position of doors and windows.
- Enter your dimensions. Snap-to-grid keeps every wall true to scale, so the plan is accurate by default.
- Add units at real sizes. Use 60cm base depths to match real-world cabinets, then drop in appliances.
- Check clearances live, then export. Watch the live measurement readout, adjust until every gap meets the minimum, and export a clean PNG to share.
That's the whole workflow — from blank room to a plan your fitter can build from, using free floor plan software with no download required.
Frequently Asked Questions
Short answers to the questions homeowners ask most when choosing a kitchen planner.
What is the best free kitchen layout planner with dimensions?
The best free option for most people is a browser-based 2D planner with snap-to-grid accuracy and live measurements, because it produces a shareable, dimensioned floor plan in minutes with no sign-up or download. Free Room Planner does exactly this and covers galley, L-shape, U-shape, island, and single-wall layouts.
Can I plan a kitchen layout online without downloading software?
Yes. Browser-based planners run entirely in your web browser with nothing to install. You draw your walls, add units, and export a floor plan as an image — all online. This removes the setup friction and works on a laptop, tablet, or phone.
Do free kitchen planners give accurate measurements?
They do when they use snap-to-grid. A planner that snaps every wall to a fixed grid, such as 10cm, keeps your layout to scale automatically, so the dimensions you share are reliable. Freehand drawing tools without snap-to-grid depend on manual entry and are far easier to get wrong.
What is the minimum aisle width for a kitchen?
The minimum single-cook aisle is 1.0m (40in), and 1.2m (48in) is recommended where two people work at once or where an oven or dishwasher door opens into the space. Anything narrower makes appliance doors and daily movement difficult.
Do I still need to follow the kitchen work triangle?
Use it as a sense-check, not a strict rule. The work triangle connecting cooker, sink, and refrigerator works well for single-cook kitchens with a total perimeter of 3.6m to 7.9m. For open-plan or multi-cook kitchens, planning two overlapping work zones often suits real life better.
Can I share my kitchen plan with a contractor?
Yes. Export your finished layout as a clean PNG and send it directly to your fitter, kitchen maker, or contractor. A dimensioned plan means fewer surprises and a smoother installation than a rough sketch. Our guide on briefing a builder with a floor plan covers what to include.
