Kitchen Layout Planner: Get the Work Triangle Right (2026)

A photo restyler will show you a beautiful kitchen, but it won't tell you whether the island you love leaves enough room to open the dishwasher. That's a layout question, and it needs a tool that works to scale. If your remodel involves moving anything — cabinets, appliances, adding an island — or you're trying to make a tight kitchen actually function, this is where you start. Here's how to plan a kitchen layout properly: the five layout types, the one rule that governs all of them, and the clearances the apps leave you to figure out.

What a layout planner does

A kitchen layout planner lets you draw your room to scale, then place cabinets, appliances, and islands and see whether they fit and flow. The good ones show measurements as you go and let you flip between a 2D plan (for getting the arrangement right) and a 3D view (for the feel of it). The point is testing your layout in your actual dimensions before you order a single cabinet — because a cabinet ordered wrong is expensive, and a layout that doesn't flow is a daily annoyance you can't easily undo.

Start with your measurements

The step that makes or breaks everything: measure your real kitchen before placing anything. Wall lengths and ceiling height, window and door positions and swings, and — critically — where the plumbing and gas lines currently are. Those utility locations are what you design around, because relocating a sink drain or a gas line is one of the priciest moves in a kitchen. Enter all of it so your digital room matches the real one.

The five kitchen layouts

Most kitchens are one of five shapes. Picking the right one for your room is the first real decision:

One-wall — everything along a single wall. Best for small spaces and studios; opens up the rest of the room.

Galley — two parallel runs with a walkway between. Highly efficient for narrow spaces, and it naturally creates a tight work triangle. Needs about a 42-inch aisle for one cook, 48 inches if two people work at once.

L-shaped — cabinets along two adjoining walls. The most versatile layout, great for small-to-medium kitchens and open-plan spaces, and it frees a corner for a table.

U-shaped — three walls of cabinetry. Maximum storage and counter space, ideal for serious cooks, but it needs roughly 8 feet wall-to-wall to leave a comfortable 48 inches clear in the middle.

Island — adds a central unit to any of the above. Great as a social hub, but an island needs at least ~40 inches (100cm) of clear walkway on every side, so it only works if the room is big enough.

A good planner lets you start from a template of any of these and adjust to your room.

The one rule that matters: the work triangle

Whatever layout you choose, the thing that determines whether the kitchen actually works is the work triangle — the path between your three busiest stations: the sink, the cooktop, and the refrigerator. The long-standing guideline:

• Each leg of the triangle should be between 4 and 9 feet
• All three legs together should total between 13 and 26 feet
• Shorter than that and the appliances crowd each other
• Longer and you walk more than you cook

It's a guideline, not a law, but it's the fastest way to sanity-check whether a kitchen will feel efficient or annoying. Several planners have a work-triangle overlay that draws the shape and measures each leg, warning you when a layout drifts out of range. Get this right and even a plain kitchen is a joy to cook in; get it wrong and a gorgeous one fights you every meal.

The clearances apps don't enforce

Planners let you place things anywhere — they won't stop you from designing something cramped. Keep these targets in mind:

• Walkways: at least 40 inches for a one-cook path, 48 inches where two people pass
• In front of appliances: enough clear floor to open the oven, dishwasher, and fridge fully — and not into each other
• Island clearance: ~40 inches minimum on all sides
• Counter landing space: room beside the stove and fridge to set things down

The best free layout planners

Planner 5D is the most beginner-friendly — draw the plan, drag in cabinets and appliances, flip to 3D. Free for the core tools; some catalog items and clean exports need a paid plan.

Homestyler offers free 3D layout building with a large cabinet and appliance catalog — good if you want to test L-shaped versus U-shaped in detail.

HomeByMe and free browser planners (like Free Room Planner) let you set exact room dimensions, place units to scale with standard sizes, check the work triangle, and export a plan to share with a fitter — often with no account.

For the tools that restyle the look rather than plan the layout, see AI kitchen design from a photo — you'll usually want both.

Where a planner stops

A planner tells you what fits, not what's possible or affordable. You can draw the range on the far wall, but the planner won't tell you that running a new gas line there costs a fortune, or that the ventilation won't reach. It also doesn't handle the code around electrical, gas, and ventilation that a kitchen requires. So prove the layout with a planner, then hand it to a contractor who can price the utility moves and confirm it meets code.

The full remodel workflow

Putting it together: use a photo tool to decide the style, a layout planner (this) to arrange the space and check the work triangle, a cost estimator to price it, and a contractor for the plumbing, gas, electrical, and build. Four quick steps, each answering its own question — and you walk into the remodel knowing what you want, that it fits, and roughly what it costs.
