The Kitchen Dimensions Every Designer Knows (And You Should Save)

Whether you’re planning a kitchen renovation or dreaming up a future remodel, understanding standard kitchen design dimensions is one of the most important steps in creating a functional and beautiful space. I get so many questions from readers and clients about proper spacing, sizing, and how to layout their kitchens for everyday use- so today, I’m sharing all of it. This is one of those handy guides you’ll want to bookmark, pin, and reference for your next kitchen remodel. Click through for the kitchen measurements interior designers use most often, along with practical tips, helpful planning insights, and industry standards that help professionally designed kitchens function beautifully- because good design is all in the details! I’m putting everything in one spot for you…

I’ve renovated my fair share of kitchens- in our own homes and for clients. Over a decade into my interior design career, I have most of these critical dimensions memorized, but these are the measurements every designer keeps at the top of their notes!

Why Kitchen Dimensions Matter in Design

It’s no secret, kitchen renovations are a big investment. Nothing is more frustrating than ending up with a layout that looks good but feels awkward when you’re cooking, entertaining, or even just putting dishes away. Getting the right measurements and layout from the start will save you money, time, and headaches down the road. From countertop height to island clearance, these dimensions create flow, function, and a kitchen that works well for your everyday life.

Standard Kitchen Dimensions You Should Know

Here’s a breakdown of the designer-approved residential kitchen measurements I reference in nearly every project…

Countertop Height

Standard: 36 inches
This is the most common and comfortable height for kitchen counters. If you’re doing custom cabinetry and you’re on the taller or shorter side, feel free to tweak slightly for ergonomic comfort… but you should know that it may affect resale value.

Designer Tip: For a more furniture-like island, you can go slightly lower with the countertop (~34 inches) for a cozy baking zone. This slight variation also adds depth. It depends how you plan to use your island!

Walkways & Traffic Paths

Minimum Aisle Width: 36 inches

This is one of the most overlooked details! You’ll want enough room to open drawers, load the dishwasher, and move around without bottlenecking traffic.

Sink & Dishwasher Spacing

Dishwasher Unloading Space: 24 inches (minimum) counter space

Always place the dishwasher directly next to the sink (preferably on the right if you’re right-handed). Leave at least 24–36 inches of counter space on one side for landing dirty dishes, drying clean dishes, or prepping.

Upper Cabinets Height

Mounting Height: 18 inches above the countertop
Cabinet Height: 30 to 42 inches, depending on your ceiling (see below)

If you have tall (non vaulted ceilings), like mine…. my preference is to stack double uppers that connect to the ceiling or crown moulding for a custom look. This spacing keeps everyday items within reach while leaving room for countertop appliances and a backsplash.

I’m using one example from my previous kitchen for this one… since all of our uppers in our current kitchen connect to the countertop.

Range Hood Height & Spacing

Range Hood Height (Electric): 24–30 inches above the cooktop
Range Hood Height (Gas): 30–36 inches above the cooktop

Proper spacing helps with ventilation and keeps the hood from feeling visually overpowering. You should alway follow the installation guidelines on your specific range hood when it comes to installation measurements for maximum function.

Designer Tip: Your hood should be wider than your cooktop. For example, if you have a 36″ range, your hood should measure at least 42″ (I have that exact scenario in the below image).

Toe Kick Dimensions

Standard Height: 3.5–4.5 inches
Depth / Overhang: 3 inches

This recessed space under your lower cabinets makes standing and working at the counter more comfortable- especially during longer food prep, cooking, or baking sessions.

Kitchen Floating Shelves

First Shelf Height: Aim for 20–24 inches above the countertop.
Spacing Between Shelves: Space them 16-22 inches apart to accommodate various items.

If you’re saving money by skipping a few upper cabinets or envision open storage, floating shelves are a great option! Be sure to plan your storage and styling carefully, but these are a fun way to display kitchen essentials. Check out my recent kitchen shelving update and peek at our coffee bar.

Kitchen Island Dimensions

Minimum Size: 24″ deep x 48″ wide
With Seating: Allow 24″ of width per barstool and 15″ overhang for legroom
Walkway Clearance: 42–48 inches between island and surrounding cabinets (if you have seating)

An island is a luxury in any kitchen, but it has to be sized properly. Too large, and it decreases functionality by cramping your kitchen. Too small, and it looks awkward.

Designer Tip: Don’t cram in an island if you don’t have the space. Instead, consider a kitchen cart or rolling butcher block. Check out this post with ideas for customizing a kitchen island or cart… you can add a lot of personality!

Kitchen Layout Guidelines That Actually Work

Even with all the right measurements & dimensions, layout matters equally as much. Here are a few tried-and-true kitchen layout rules I keep in my back pocket, as an interior designer…

The Work Triangle Dimensions

The classic “work triangle” connects the sink, stove, and refrigerator. Ideally, these points should form a triangle with each leg measuring between 4 and 9 feet. It’s all about minimizing steps and creating efficiency.

Landing Zones

You need designated places to set things down and specific work zones… these are great for resting hot pans, groceries, dishes, or a place to food prep. Typically, these are the minimum measurements for those areas:

• Next to the fridge: at least 15 inches of counter space
• Next to the oven: 15 inches minimum
• Next to the sink: 15–24 inches

Personal Advice from My Own Renovations

In our kitchen remodel, one of the most valuable changes I made was increasing the aisle width or traffic path to 40 inches (from the standard 36″). It made a big difference for both daily use and entertaining. Everyone gravitates toward the kitchen and there is plenty of room to move around our island.

Another detail I’m glad we prioritized? Oversized drawers on the lower cabinets instead of traditional cabinet doors- they’re easier to access and make organizing so much more manageable. Speaking of organization, check out this post with 15 aesthetically pleasing kitchen storage & organization ideas (with examples of each).

Aside from panel ready appliances, a designated pantry cabinet, and an appliance garage, my non negotiable is hidden trash! It’s an easy upgrade: how to install a hidden kitchen trash can.
