Microwave Drawer Dimensions: The Aisle It Needs
A microwave drawer is 24 or 30 inches wide and 15 to 16 inches tall, and the cabinet needs 16 to 17 inches of clear interior height to take it. The measurement people forget is the aisle: the drawer slides 24 to 26 inches into the room, so a tight island walkway loses the drawer even when the cabinet fits.
How big is a microwave drawer?#
A microwave drawer is 24 or 30 inches wide, 15 to 16 inches tall and 23 to 24 inches deep, and it drops into a base cabinet that has 16 to 17 inches of clear interior height. Those numbers describe the cabinet side of the job. The side that gets missed is the room: unlike a door, a drawer travels, sliding 24 to 26 inches out into the aisle every time it opens. In an island with a walkway that is the measurement that decides everything, so the table below starts there.
Microwave drawer dimensions by configuration#
| Configuration | Width (in) | Height (in) | Depth (in) | Best for |
|---|---|---|---|---|
| 24-inch island microwave drawer | 24 | 15–16 | 23–24 | a pull-out in a kitchen island |
| 30-inch base-cabinet microwave drawer | 30 | 15–16 | 23–24 | a wider pull-out under the counter |
| 24-inch drawer below a wall oven | 24 | 15–16 | 23–24 | stacking under a wall oven column |

Your island and your cabinet, measured#
Measure the walkway in front of the cabinet face, the cabinet opening, and the clear height inside it. The aisle is usually the one that decides.
| What you measured | What it takes | The clearance that decides it |
|---|---|---|
| An aisle under 24 in in front of the cabinet face | Nothing on this page opens fully | The drawer slides 24 to 26 in into the room; a tight island walkway loses the drawer no matter how well the cabinet fits |
| A base-cabinet opening 24 in wide | 24-inch island drawer, or the 24-inch drawer below a wall oven | Both are 23 to 24 in deep and drop into the same opening — what differs is what sits above them |
| A base-cabinet opening 30 in wide | 30-inch base-cabinet drawer | The wider class buys interior width at the same 15 to 16 in of case height |
| Clear interior cabinet height under 16 in | None of the three | The case is 15 to 16 in tall, but the cabinet needs 16 to 17 in for the unit to drop in and still connect |
| Cabinet back tight against the wall | Any class — this is the design | It vents through the front, so it installs flush in a base cabinet with no rear gap at all |
Three configurations are counted here, and the case is nearly identical across all of them — this class varies by where it goes, not by how big it is. The pull-out clearance is a travel distance rather than a dimension of the appliance, which is why it appears in no width, height or depth figure anywhere.
Installation clearances for a microwave drawer#
- Base-cabinet opening: 24–30 in in of cabinet width a microwave drawer needs, matched to the nominal size.
- Drawer pull clearance: 24–26 in in of front room a microwave drawer needs to slide fully open.
- Interior cabinet height: 16–17 in in of clear cabinet height a microwave drawer needs to drop in and connect.
- Front venting: A microwave drawer vents through its front, so it installs flush in a base cabinet with no rear gap.

Will your microwave drawer fit? Clearances and door swing#
A microwave drawer lives in a base cabinet, so the opening is what governs the fit. Match the base-cabinet opening to the nominal size — 24 or 30 inches wide — and confirm 16 to 17 inches of clear interior cabinet height so the unit can drop in and connect. Depth of 23 to 24 inches has to clear inside the cabinet. Because it vents through its front, a microwave drawer installs flush with no rear gap, which is exactly what lets a designer bury it in an island far from the range. The moving part to plan for is the drawer itself: it needs 24 to 26 inches of front room to slide fully open, so an island walkway has to swallow the open drawer. Confirm the cabinet width, the interior height, and the front clearance, and make sure a grounded outlet is reachable in the cabinet.
Microwave drawer sizes by type: 24-inch island microwave drawer, 30-inch base-cabinet microwave drawer, 24-inch drawer below a wall oven#
The 24-inch island microwave drawer is the signature use, a pull-out set into a kitchen island so the microwave disappears from the wall and opens at a comfortable height. The 30-inch base-cabinet microwave drawer is the wider version for a base cabinet under the counter, giving more interior room while keeping the same low 15-to-16-inch height. The 24-inch drawer below a wall oven is the stacking configuration, tucking under a wall oven column so the two share a cabinet run. All three are the same height and depth and vent from the front, so the choice is width and location: 24-inch for an island or under a wall oven, 30-inch when you want the larger cavity in a base cabinet. Pick the spot first, then match the cabinet opening.
