Pick a countertop microwave if you have free counter space and want simple placement; pick an over-the-range model to free the counter and replace a hood. The countertop microwave vs over range microwave decision comes down to your cabinet opening, your venting and how much counter you can spare.

The TOSHIBA countertop model scores 9.6 and takes the overall win for most kitchens. It drops onto a free counter, holds a 12.4-inch turntable and adds sensor cooking without any cabinet work.

The over-the-range models score 9.5 and 9.3, and they win when counter space is the problem. They mount above the stove and carry a vent fan, but you need a cabinet opening and a vent route to fit one.

Countertop vs over-the-range microwave: the two side by side

The core trade is counter space against installation work. A countertop unit asks for a free stretch of counter; an over-the-range unit asks for a cabinet opening and a vent path.

Both units run at 1000W and both include a 12.4-inch turntable, so basic heating power is a tie. The over-the-range model gains capacity and a vent fan; the countertop model gains placement freedom.

Width is the biggest physical gap. The BLACK+DECKER over-the-range unit is 29.9 inches wide, which means a 30-inch cabinet opening above the stove.

The TOSHIBA needs about 21 inches of free counter.

The over-the-range unit also needs a vent route. It ships with a 300 CFM two-speed vent fan and a light, so it takes over the hood's job.

A countertop unit clears no fumes at all, so a separate hood or fan still has to handle that.

The countertop model carries extras the over-the-range unit doesn't. It has Smart Sensor Technology that adjusts time and power to food humidity, six preset menus for foods like pizza and veggies, and 10 power levels for everything from defrosting to boiling liquids.

The over-the-range unit keeps 10 cooking levels too, but its quick menus are simpler: popcorn, beverage, melt/soften, reheat and defrost.

The first thing that decides the choice: where it will go

If you have a free counter run, a countertop microwave is the easier fit; if the counter is full, the over-the-range layout solves the space problem. Placement decides more than any feature.

Measure the spot before you compare models. A countertop unit needs its full footprint plus airflow and door swing.

The TOSHIBA is 20.6 inches wide and 14.6 inches deep, so mark about 21 by 15 inches on the counter and stand there.

An over-the-range unit needs the cabinet opening above the stove. The BLACK+DECKER units are 29.9 inches wide, so a standard 30-inch opening is the target.

The space above your stove also has to clear the microwave's height.

If your kitchen already has a hood, an over-the-range model can take its place. If there's no hood and no vent route, a countertop unit keeps things simple.

This is also where many buyers go wrong. They buy a large countertop model and then find it crowds the prep area or blocks a cabinet door.

Measure first, then choose the type.

Weight is part of the install plan too. The over-the-range BLACK+DECKER units weigh 49 pounds and need lifting into place.

The TOSHIBA is 34.8 pounds and just sets down on the counter. If you can't picture two people lifting a 49-pound box above the stove, the countertop type is the honest choice.

The second thing: counter space versus cabinet space

A countertop microwave costs you horizontal counter, while an over-the-range model costs you cabinet space. You are trading one kind of space for another.

Counter space is the hardest thing to win back in a small kitchen. A 21-inch-wide microwave can eat a third of a short counter run.

That matters if you prep food in the same spot.

An over-the-range unit uses the space you already reserved for a hood. The BLACK+DECKER models sit above the cooktop, so the counter stays clear.

That's the main reason people choose this layout.

The cost is cabinet room above the stove, and the model's height matters when it hangs over the burners.

The BLACK+DECKER over-the-range units stand 16.4 inches tall.

The depth figures matter here too. The TOSHIBA runs 14.6 inches deep and the over-the-range BLACK+DECKER runs 13.2 inches deep.

A deeper countertop model pushes forward and eats into standing room at the counter. A shallower over-the-range unit clears the cooktop without jutting into your face.

If your counter is short and your cabinet run above the stove is free, the over-the-range layout is the clear pick. If your counters are generous and your cabinets are packed, a countertop model keeps the cabinet for storage.

Our guide on how to choose a microwave walks through these room measurements before you commit.

The third thing: venting and the cooktop above

Only the over-the-range models here clear cooking fumes; the countertop models don't vent at all. That single difference often decides the type.

Both BLACK+DECKER over-the-range units carry a 300 CFM vent fan with two speeds and an integrated light. That fan clears smoke and odors from the cooktop and lights the burners while you cook.

A countertop microwave has no vent fan. If you cook on a gas or electric range, you still need a hood or an exhaust fan over it.

The microwave does nothing for the air.

This is where the layout wins or loses. If you already have a hood and a vent route, an over-the-range unit replaces both.

If you don't have a vent route, the microwave's fan may only recirculate air through a filter, so check the ducting.

If you rarely cook on the stove, the vent matters less. A countertop model plus an existing hood can cover both jobs without a cabinet opening.

What the vent fan changes in daily cooking

The 300 CFM fan earns its place when you sear, fry or broil on the stove. A two-speed fan lets you run low for a simmer and high for smoke.

The integrated light is the second half of the hood's job. It focuses light on the cooktop, so you can see browning without leaning in.

If your stove sits under a cabinet with no duct, the same unit may recirculate through a filter. That handles light odors but not heavy smoke.

Plan the vent route before you buy, not after.

A countertop model leaves all of that to your existing hood. That's fine if the hood works, and a problem if it doesn't.

The fourth thing: capacity and what fits inside

Over-the-range models here offer more cubic feet, but a 1.2 cu ft countertop still holds a full dinner plate. Capacity follows the type, not the brand.

The BLACK+DECKER over-the-range unit holds 1.7 cu ft. The air fryer version holds 1.5 cu ft.

The TOSHIBA countertop holds 1.2 cu ft and the small BLACK+DECKER holds 0.9 cu ft.

That gap matters for big dishes. A 1.7 cu ft interior takes larger casserole dishes and taller containers.

A 1.2 cu ft interior covers everyday plates and bowls.

If you regularly reheat family-size dishes or large platters, the over-the-range capacity helps. If you mostly heat plates, mugs and leftovers, the smaller countertop interior is enough.

Turntable size is the other limit. Two of these models have a 12.4-inch turntable, so a standard dinner plate fits on each.

The air fryer model's turntable is 13.6 inches. The small BLACK+DECKER's 10.6-inch turntable is tighter.

Our post on what size microwave fits a dinner plate explains how to check plate clearance.

If you want more countertop room for large dishes without going over the range, our large countertop microwave picks cover the bigger counter models.

Cooking modes and controls beyond capacity

Capacity isn't the only difference inside. The TOSHIBA's humidity sensor takes the guesswork out of reheating, so leftovers come out evenly hot without you picking a time.

Its 10 power levels let you drop to low for softening butter or boiling liquids gently.

The BLACK+DECKER over-the-range unit runs multi-stage cooking. You can cook at 90 percent power for 10 minutes and then at 50 percent for 20 minutes in one setting.

That suits recipes that need a strong start and a gentle finish.

The air fryer model goes further with six functions: microwave, air fryer, convection, combi (grill), bake and roast. It also has sensor reheat for leftovers and auto defrost.

If you want an appliance that does more than reheat, that model covers it without taking counter space.

The small BLACK+DECKER keeps it simple with six presets for popcorn, potato, pizza, frozen vegetable, beverage and dinner plate. It also has a 30-second express cook and a child safety lock.

Simple controls suit a household that just wants quick reheats.

Who should buy which

Buy a countertop microwave if your install has to be simple or you rent; buy an over-the-range model if you're replacing a hood and want the counter back. The type should follow your kitchen, not the other way around.

Buy a countertop model if...

You rent and can't cut a cabinet opening. A countertop unit needs no permanent change, so it moves out when you do.

You already have a range hood. Adding an over-the-range microwave means pulling the hood, so a countertop unit lets the hood keep its job.

You want the simplest repair and replacement path. A countertop unit lifts off the counter; an over-the-range unit has to be unmounted from the cabinet.

You need a compact fit. The small BLACK+DECKER 0.9 cu ft model measures 18.7 x 13.4 x 10.7 inches and suits tight counter corners.

Our white countertop microwave picks cover color matches for open kitchens.

Buy an over-the-range model if...

Counter space is your bottleneck. The BLACK+DECKER 1.7 cu ft model clears the whole counter run.

You're replacing an old hood. The 300 CFM vent and light do the hood's job and save the separate unit.

You want more cooking modes without more counter. The air fryer version adds air fry, convection, bake and grill to the microwave.

You cook big meals. The 1.7 cu ft interior takes larger dishes than the countertop picks here.

A quick way to decide

Count your free counter inches first. If the answer is under about 21 inches and the spot sits under a cabinet, the countertop type may not fit at all.

Then look above the stove. A free cabinet run plus a vent route points to over-the-range.

A packed cabinet run or no vent route points to countertop.

The verdict: which type wins for most kitchens?

For most kitchens, the TOSHIBA countertop model wins on score at 9.6, because it installs in minutes and covers everyday heating. It's the best overall pick in this countertop microwave vs over range microwave matchup.

The TOSHIBA brings 1000W, sensor cooking, 10 power levels and a 12.4-inch turntable. It fits on about 21 inches of counter and needs no cabinet or vent work.

The BLACK+DECKER over-the-range model wins when counter space is short or a hood needs replacing. Its 1.7 cu ft interior and 300 CFM vent fan are the reasons to mount one.

The air fryer version is the pick if you want convection and air fry modes above the stove. It gives up some power at 900W but adds cooking modes the others don't have.

The small BLACK+DECKER wins only when the footprint is the hard limit. At 0.9 cu ft it's the tightest fit here, but its smaller turntable limits what goes inside.

If your counter is full and your stove has a vent route, choose an over-the-range model. If the install has to stay simple, choose the TOSHIBA countertop.

Frequently asked questions

Is a countertop or over-the-range microwave better?

A countertop model is better when you have free counter space and want the simplest install. An over-the-range model is better when counter space is tight and you need a vent fan, but it requires a cabinet opening and a vent route.

Do over-the-range microwaves need special installation?

Yes. An over-the-range model mounts under a cabinet above the stove and needs a vent path, either to the outside or through a recirculating filter.

Plan the cabinet opening, the electrical outlet and the venting before you buy.

Can a countertop microwave go under a cabinet?

Only with clear space around it. A countertop model needs airflow on the sides and top, so check the cabinet height against the microwave's dimensions.

A tight fit under a cabinet can trap heat and block the door swing.

How much counter space does a countertop microwave take?

This TOSHIBA measures 20.6 inches wide by 14.6 inches deep, so plan about 21 by 15 inches of free counter. Leave room in front for the door swing and some space around the cabinet for airflow.

Which type offers more cooking space?

Over-the-range models usually offer more. The BLACK+DECKER over-the-range units here hold 1.7 and 1.5 cubic feet, against 1.2 for the TOSHIBA countertop and 0.9 for the small BLACK+DECKER.

Does an over-the-range microwave replace a range hood?

Yes, if it has a vent fan. The BLACK+DECKER over-the-range models include a 300 CFM two-speed vent fan and light, so they clear fumes and light the cooktop in place of a separate hood.
