Kitchen Layouts: Galley, L, U, Island and Peninsula Compared

By the JDI Construction teamReviewed by Arthur Kulchitskiy, CEOUpdated October 20266 min read

Quick answer

The room picks the layout more than taste does. Narrow rooms suit a galley, corner rooms an L, three-walled rooms a U, and an island needs enough width for aisles on every side. The NKBA recommends work aisles of at least 42 inches for one cook and 48 inches for two, and walkways of at least 36 inches. These are planning guidelines, not building code.

A kitchen layout is the arrangement of counters, appliances and walkways, and it is the one decision that cannot be fixed later with better finishes. Start with the shape of the room and the way people move through it, then see which of the five standard layouts fits. Most kitchens are one of these or a combination of two.

The five layouts compared

Layout	Room it fits	Strengths	Weaknesses
Galley (two parallel runs)	Long, narrow rooms; kitchens between two other rooms	Very efficient for one cook; everything within a step or two; no corner cabinets	Tight for two cooks; becomes a hallway if both ends are open
L-shape	Corner rooms; kitchens open to a dining or living area	Keeps traffic out of the work area; leaves floor for a table or island	One corner cabinet to resolve; long legs spread the appliances apart
U-shape	Rooms with three usable walls	Most counter and storage per square foot; cook is surrounded by work surface	Two corners; feels closed in if the room is narrow; one way in and out
Island	Wide rooms, usually an L or single wall plus a freestanding island	Prep space facing the room; seating; a second work zone for another cook	Needs clear aisles on all sides; utilities must come through the floor
Peninsula	Rooms too narrow for an island; a wall opened to the next room	Island-style counter and seating with one less aisle; easy to supply with plumbing and power from the attached wall	Creates a dead-end entry; adds a corner

Galley

Two runs of cabinets face each other across one aisle. Professional cooks like galleys for a reason: nothing is more than a turn away. The layout fails when the aisle is the main route to the back door or the garage, because everyone walking through passes between the cook and the range. If you have a galley with a door at each end, the first thing to look at is whether one opening can be closed or relocated. Put the sink and range on the same side where possible, so hot pans and wet dishes do not cross the aisle.

L-shape

Counters run along two adjoining walls. The open side lets traffic pass without entering the work area, which is why the L is the most forgiving layout for family life. Its limits show up when one leg gets long: the refrigerator ends up far from the sink, and the corner becomes deep storage that is hard to reach. Corner solutions are covered in kitchen storage and pantries. An L is also the usual starting point for adding an island.

U-shape

Counters wrap three walls. A U gives the most continuous counter and is ideal for a single serious cook. Check the distance between the two facing runs before committing. Too narrow and two people cannot pass; too wide and the efficiency is gone. In a tight U, replacing one leg with a peninsula, or removing upper cabinets from one side, opens the room without losing the shape.

Island

An island is a layout only if the room can afford it. The island itself is rarely the constraint. The aisles around it are. Take the width of the room, subtract the depth of the wall cabinets and the island, and what remains has to be split into aisles that meet the numbers below. If the arithmetic does not work, the result is an obstacle in the middle of the kitchen. Sizing, seating overhangs, sinks and power are covered in kitchen islands.

Peninsula

A peninsula is a counter attached to a wall or cabinet run at one end and open at the other. It gives most of what an island gives while needing one aisle fewer, which makes it the practical answer for many rooms. It is also the natural result of opening a wall between the kitchen and the next room down to counter height. The trade-off is circulation: a peninsula turns the kitchen into a room with a single entry.

NKBA planning numbers

The National Kitchen & Bath Association publishes 31 kitchen planning guidelines. Designers use them as a starting point and a sanity check.

Item	NKBA guideline
Work aisle (between counter fronts, tall cabinets or appliances)	At least 42 inches for one cook, at least 48 inches for multiple cooks
Walkway (a passage that is not a work aisle)	At least 36 inches
Work triangle (sink, cooking surface, refrigerator)	Three legs totaling no more than 26 feet; no leg under 4 feet or over 9 feet
Traffic	No major traffic pattern should cross the work triangle
Sink landing areas	At least 24 inches on one side and 18 inches on the other
Cooking surface landing areas	At least 12 inches on one side and 15 inches on the other
Refrigerator landing area	15 inches on the handle side
Dishwasher	Nearest edge within 36 inches of the sink; 21 inches of standing room beside it
Seating, with traffic behind	36 inches to edge past a seated diner, 44 inches to walk past

What is code, and affects layout

A few real code requirements do shape where things can go:

Clearance above the range. The residential code requires at least 30 inches from the cooking top to unprotected combustible material above, unless the listing of the hood or appliance allows less.
Countertop outlets. Along a wall counter, no point may be more than 24 inches from a receptacle, which affects where windows, tall cabinets and appliance garages can interrupt a run. See the kitchen electrical code page.
Hood ducting. Cooking exhaust has to discharge outdoors through a duct, so the range location needs a workable duct route. See range hoods and ventilation.
Structure. In the City of Vancouver, adding or removing a wall requires a residential building permit. See opening a kitchen wall.

How to choose for your room

Draw the fixed things first: exterior walls, windows, doorways you cannot move, and the main path people take through the room.
Keep traffic out of the work area. If the route from the garage to the family room runs between sink and range, fix that before anything else.
Place the sink. It is the most-used station and the most expensive to move. The NKBA suggests locating a single sink next to or across from the cooking surface and the refrigerator.
Protect one long prep counter of at least 36 inches next to the sink.
Check the aisles against the table above, with appliance doors open.
Only then consider an island or peninsula, and only if the aisles survive.

The age of the house often narrows the choice. In Vancouver the two largest decades of housing are the 1990s and the 1970s, at 21.0 percent and 18.1 percent of housing units in the Census Bureau's 2020-2024 American Community Survey, and homes from different decades were built around different kitchen shapes.

Seeing a layout before it is built

Floor plans are hard to read for clearances. JDI provides a 3D design layout as part of its planning, so aisle widths and sightlines can be judged before cabinets are ordered.

Common questions

Is the work triangle still relevant?

It is a useful check, not a design method. Modern kitchens often have two cooks, a second sink or a separate beverage area, so designers think in zones for prep, cooking and cleanup. The triangle still catches the two classic faults: appliances too far apart, and a traffic path cutting between the sink and the range.

Where should the refrigerator go?

Near the kitchen entry, at the end of a run. People who are not cooking use the refrigerator more than anything else, so placing it at the edge keeps them out of the work area. The NKBA recommends 15 inches of landing counter on the handle side, or within 48 inches across from the front.

Can I put the range on an island?

Yes, but plan the ventilation first. Washington's residential code requires domestic cooking exhaust to discharge outdoors through a duct, so an island range needs a ceiling-mounted hood ducted up and out, or a downdraft unit ducted below the floor. The NKBA also recommends at least 9 inches of counter behind an island cooking surface.

How much countertop does a kitchen need?

The NKBA guideline is a total of 158 inches of countertop frontage, 24 inches deep, with at least 15 inches of clearance above. It also recommends one continuous section at least 36 inches wide next to a sink for preparation. Many compact kitchens fall short of the total and still work well if that prep section is protected.

Does changing the layout always mean moving plumbing?

No. Many layout improvements keep the sink where it is and move cabinets, the refrigerator or the range around it. Keeping the sink on its existing drain and vent is the single largest way to hold down the cost of a new layout.
