How big is an under-cabinet range hood?#
Tucked beneath a wall cabinet, this vent is a slim canopy, 30 or 36 inches wide and a mere 3 to 8 inches deep in body height. The table below lists the 30-inch, 36-inch, and slim liner builds.
Under-cabinet range hood dimensions by configuration#
| Configuration | Width (in) | Height (in) | Depth (in) | Best for |

Installation clearances for an under-cabinet range hood#
- Mounting height above cooktop: 24–30 in in the manufacturer wants between the cooktop and the bottom of an under-cabinet range hood.
- Duct clearance: 6 in in of space behind an under-cabinet range hood for the duct transition to the wall or roof.
- Cabinet width match: 30–36 in in of cabinet the under-cabinet range hood mounts under, matched to the cooktop width below.
- Vent duct: An under-cabinet range hood ducts up through the cabinet above or straight back through the wall behind it.
Will your under-cabinet range hood fit? Clearances and door swing#
Since the canopy hides under the cupboard over the cooktop, the fit comes down to matching the cabinet width and setting the right height over the flames. Hang it 24 to 30 inches above the burners as the maker directs — near enough to grab steam, far enough for headroom and tall pots. The unit should line up with the 30 or 36-inch cupboard it hangs beneath, which in turn tracks the cooktop width. Behind the body, spare roughly 6 inches so the duct transition can pivot up through the cupboard or straight out the wall. At just 3 to 8 inches of body height, it hardly bites into the storage overhead, which is its chief advantage over a bulky chimney canopy. Trace the duct route before mounting, since it heads either upward or rearward.

Under-cabinet range hood sizes by type: 30-inch under-cabinet range hood, 36-inch under-cabinet range hood, slim under-cabinet hood liner#
The three builds follow cupboard width and how much bulk you accept. The 30-inch canopy, 5 to 8 inches deep in body and 18 to 20 front to back, is the everyday choice for a common cooktop. The 36-inch version spans a broader burner set and runs a touch deeper at 19 to 21 inches. The slim liner shaves the body to only 3 to 5 inches for a low-key profile under a shallow cupboard, preserving nearly all the shelf space above. Pin the width to the cooktop, then choose a full body or the slim liner by how much storage you want to keep.
Under-cabinet range hood dimensions: common questions#
How wide is an under-cabinet range hood?#
They arrive in 30 and 36-inch widths to suit standard cooktops and the cupboard they hang beneath. Thirty inches is the everyday size.
How high above the cooktop should an under-cabinet hood mount?#
Set it 24 to 30 inches over the burners per the maker's sheet. That window grabs steam well while leaving clearance for cookware.
How deep is an under-cabinet range hood?#
Front to back it measures 17 to 21 inches, so it nests under a 12-to-13-inch cupboard with the face jutting a little past it. The slim liner sits shallowest at 17 to 19.
What size hood do I need for a 36-inch cooktop?#
A 36-inch cooktop wants a 36-inch canopy so the capture spans every burner. Equal widths keep the pull even edge to edge.
How much clearance does an under-cabinet hood need for the duct?#
Allow about 6 inches at the rear for the duct to bend up through the cupboard or back through the wall. Map that route before you fasten anything.
