Typical over-the-range microwave dimensions are about 30″ wide, 17″ high, and 16″ deep, but models range from roughly 24–36″ wide.
If you’re shopping for a new unit, the dimensions of a microwave over the range decide whether it slides in neatly or turns into a headache. Getting the numbers right keeps your cabinets safe, your cooktop comfortable to use, and your vent working the way it should every day.
Typical Dimensions For A Microwave Over Your Range
Most full size over-the-range microwaves stay close to a shared standard so they match 30 inch ranges, with shells around 30 inches wide, 16–18 inches high, and 15–18 inches deep with the door closed.
| Style | Typical Width | Typical Height & Depth |
|---|---|---|
| Compact 24″ OTR | 23.5″–24.5″ | 16″–17″ high, 15″–16″ deep |
| Low Profile OTR | 29.5″–30″ | 10″–11″ high, 18″–19″ deep |
| Standard 30″ OTR | 29.5″–30″ | 16″–18″ high, 15″–17″ deep |
| Large Capacity 30″ OTR | 29.5″–30″ | 17″–18″ high, 16″–18″ deep |
| Wide 36″ OTR | 35.5″–36″ | 16″–18″ high, 15″–17″ deep |
| Older Compact Models | 26″–28″ | 15″–17″ high, 14″–16″ deep |
| Over-The-Range Convection | 29.5″–30″ | 17″–18.5″ high, 16″–18.5″ deep |
The width, height, and depth in this range line up with standard cabinet runs and 30 inch ranges, which is why most showrooms display similar shells even across different brands.
Width And Cabinet Run
The width of your cabinet run above the stove controls nearly every choice you make, since a 30 inch range usually sits between two base cabinets with a 30 inch cabinet or hood above it. Manufacturers build most over-the-range units to fill that span so the front face lines up with the cabinet doors on each side.
If you have a 36 inch wide range or custom hood, you may see fewer over-the-range microwaves that match that span, but some wide models exist in higher price brackets.
Height And Head Room
Height links directly to comfort and safety. The bottom of the microwave needs to clear tall pots while keeping controls within easy reach. Many installation guides point to a mounting height that leaves about 30 inches between the cooktop and the bottom of the cabinet or bracket.
For most households, an exterior height between 16 and 17.5 inches hits a practical sweet spot. Low profile designs keep the housing shorter so they can squeeze under shallow cabinets while still clearing the burners, while big capacity models add a bit of height to gain interior room.
Depth And Door Swing
Depth decides how far the front of the microwave sticks past the cabinets and how far the door swings into the cooking zone. Standard units sit around 15 to 17 inches deep with the door closed, which keeps the handle near the cabinet faces without blocking the front burners.
Door swing matters in tight kitchens. The hinge side usually needs at least half an inch of space from a nearby wall or tall pantry cabinet so the door can open fully. If you crowd that side, large platters may scrape as you slide them in and out.
Dimensions Of A Microwave Over The Range In Standard Kitchens
This section walks through the practical numbers that shape over-the-range microwave sizing in a typical home. You’ll match the outside size to your cabinets, allow air to move through the vent, and still keep the controls easy to reach for everyone who cooks.
Step One: Measure The Cabinet Opening
Grab a tape measure and write down three measurements above your range: the width between the side cabinets, the height from the cooktop to the bottom of the cabinet, and the cabinet depth. Those figures guide every size choice you make.
Most over-the-range models ask for a minimum cabinet width of 30 inches, a cabinet depth between 12 and 13 inches, and at least 30 inches between the cooktop and the bottom of the cabinet. If your cabinet sits lower, a low profile unit or a small cabinet change may be needed.
Step Two: Check Mounting Height And Clearances
Once you know the cabinet opening, compare it with the installation notes for each model. Brands often list a mounting height that leaves about 30 inches from the cooktop to the bottom of the cabinet or bracket and give a small allowed range. Stay near the lower end if someone in the home is shorter.
Step Three: Venting Space And Ductwork
An over-the-range microwave doubles as a hood, so the body holds a blower and either a filter for recirculating air or a duct that sends steam outdoors. The dimensions need to leave room for that air path. If you plan to vent outside, check that there is space above the cabinet for a six inch duct and any elbows the manual lists.
Some homes already have a wall or roof vent in place from an older hood. In that case, you may be locked into a specific vent location, which can narrow the list of models that line up with the existing opening without extra carpentry.
How Dimensions Affect Daily Cooking
Once the tape measure work is out of the way, the next question is feel. A microwave that meets the minimum installation notes can still feel cramped if the cabinet run sits low or if the main cook is tall.
Reach, Visibility, And Safety
Think about who uses the stove most often. If a teenager or a shorter adult reheats dinner every night, a high mounted microwave forces them to lift hot bowls close to eye level. A shorter unit or a lower cabinet run can ease that strain.
Lighting also links to height. Many over-the-range models include lights under the body to shine on the front burners. If you mount the unit too high, that light spreads out and feels dim. Too low, and the housing blocks sight lines to the back burners.
Clearance Over Gas And Electric Ranges
Gas burners throw more heat and open flame, so appliance makers publish a minimum distance above the highest grate for safe use. Staying within that span protects both the warranty and the lower trim of the microwave door.
Choosing Dimensions For Different Kitchen Layouts
The right dimensions of a microwave over the range depend on how your kitchen handles traffic, storage, and cooking habits. A long wall with deep counters can host a large capacity model, while a narrow rental kitchen favours a low profile option that leaves more open head room.
| Area | Recommended Space | Reason |
|---|---|---|
| Cooktop To Bottom Of Microwave | 30″–36″ in many guides | Room for tall pots and good venting |
| Cabinet Depth | 12″–13″ common | Aligns with standard wall cabinets |
| Door Swing Clearance | >= 0.5″ on hinge side | Lets door open fully near a wall |
| Upper Cabinet Interior | At least 30″ wide | Room for mounting plate and bolts |
| Top Clearance For Duct | 4″–6″ above cabinet | Space for vent collar and elbow |
| Side Clearance To Tall Units | 1″–2″ if possible | Helps doors, drawers, and handles clear |
| Interior Capacity | 1.5–2.1 cu ft common | Fits dinner plates and casserole dishes |
Retail guides such as the Home Depot microwave measuring page and the microwave dimensions guide from KitchenAid show similar clearance ranges, and installers usually follow the stricter of the appliance manual and local code.
Small Kitchens And Apartments
In a compact space, cabinet runs above the stove sit closer to eye level and may fall under the usual 30 inch mark above the cooktop. That limits microwave height. Check 24 or 27 inch wide models or low profile 30 inch units that tuck higher under a shallow cabinet.
These smaller units often trade a bit of depth or interior capacity for breathing room. If you mostly reheat plates and steam vegetables, that trade feels fine. If you love tall casserole dishes or wide baking pans, you may prefer a deeper unit and a raised cabinet.
Busy Family Kitchens
For larger homes, a standard 30 inch wide over-the-range microwave around 17 inches high and 16 inches deep fits a wide mix of cookware. Interior capacities between 1.7 and 2.1 cubic feet leave space for tall mugs, popcorn bags, and family style leftovers.
In these spaces, door swing and traffic lanes matter a lot. Make sure the handle clears nearby fridge doors and tall pantry cabinets, and think about how far people need to step back when the door is open. A crowded corner turns a simple reheat task into a bumping match on busy weeknights.
Tall Cooks And Accessibility
If the main cook stands above average height, you may be tempted to mount the microwave higher for a more open feel. That might work, but check the reach of shorter family members before you drill. Kids who heat food alone should not have to lift dishes above shoulder level.
Households with wheelchair users or people who have limited reach may be better off with a countertop or built in microwave placed at a lower height, even if the range area already has a hood. Safety and ease of use matter more than gaining one extra cabinet shelf.
Simple Takeaways On Over The Range Microwave Dimensions
Standard over-the-range microwave dimensions sit near 30 inches wide, 16–18 inches high, and 15–18 inches deep, with low profile or compact models using shorter or narrower shells. Those outside numbers still have to match your cabinet opening, vent path, and comfort over the cooktop.
Once you settle on a width that fits the cabinet run, check height, depth, clearances, and interior capacity against how you cook. With a tape measure and the installation notes for your chosen model, you can match the appliance to your space without guesswork.
