Range Hood Install Height: The Short Answer
The most common mistake in a kitchen ventilation project isn't picking the wrong hood — it's hanging the right hood at the wrong height. Get the range hood install height wrong and even a powerful, expensive hood will leave smoke drifting across your kitchen. The good news is that the correct height follows a few clear rules, and it's usually the very first measurement you lock in during range hood installation, because it drives your cabinet and duct layout.
Here's the quick answer most people are looking for: the majority of hoods install 24 to 30 inches above the cooking surface, measured from the cooktop to the bottom of the hood. Gas cooktops sit toward the higher end of that range (and sometimes above it), electric and induction cooktops can sit a touch lower, and island hoods go higher still. Before you drill a single hole, though, confirm the number in your specific range hood manual — manufacturers set their own clearances, and that spec is the final authority.
So here's the core rule of this guide: most range hoods belong 24–30 inches above the cooktop, with gas cooktops toward the higher end (up to about 36 inches) and island hoods higher still at 30–36 inches — but the number that actually matters is the one in your model's manual, because it's set by the hood's design, your fuel type, and your cabinet layout. Mount it too high and the hood can't catch the smoke; mount it too low and you risk heat damage. Get it right and the hood you paid for actually performs.
Range Hood Install Height by Cooktop Type
Mounting height is driven first by what's underneath the hood. The more heat and open flame your cooktop produces, the more clearance the hood needs for both safety and airflow.
Gas Cooktops: 24–36 Inches
Gas burners produce an open flame and a higher ambient heat output, so they need the most clearance. Most manufacturers recommend installing the hood 24 to 36 inches above a gas cooktop, and for high-BTU or professional-style burners, many guides point to the upper part of that band (around 28–36 inches). ROBAM's own guidance for gas ranges is 24–36 inches — enough clearance to keep the hood safely away from the flame while still capturing rising smoke and grease. If you run a burner rated above 12,000 BTU, check the manual specifically, as high-output burners can require extra clearance.
Electric Cooktops: 24–30 Inches
Electric coil and radiant cooktops give off less ambient heat and have no open flame, so the hood can sit a little closer to the surface. A common recommendation is 24 to 30 inches above an electric cooktop, and some models allow as low as 20–24 inches. Lower placement improves smoke capture, but keep it high enough to clear cookware, avoid head bumps, and keep your sightlines to the back burners open.
Induction Cooktops: Follow the Manual (Usually 24–30 Inches)
Induction is the source of the most confusion. Because induction heats the pan directly and the cooktop stays cool to the touch, it produces very little ambient heat — which tempts people to mount the hood low. But the food still generates grease, steam, smoke, and strong odors, so the hood still has to capture a full plume. Treat induction much like electric: 24–30 inches is a safe starting point, and the model's manual settles it.
Range Hood Install Height by Hood Type
Your fuel type sets the baseline; the style of hood adjusts it. Where the hood mounts and how exposed it is to room air both matter.
Under-Cabinet and Wall-Mount Hoods: 24–30 Inches
Under-cabinet hoods tuck beneath existing cabinetry and wall-mount (chimney) hoods fix directly to the wall; both typically install about 24 to 30 inches above the cooktop. Because a wall-mount hood's chimney is visible, plan the height so the canopy lands in that window and the chimney cover telescopes cleanly to your ceiling. Measure from the cooktop surface to the bottom of the canopy, not to the top of the chimney.
Island Hoods: 30–36 Inches
An island range hood hangs over a cooktop that's open on all four sides, so cross-drafts pull the cooking plume sideways before it can rise into the canopy. To compensate, island hoods are usually installed a little higher — 30 to 36 inches above the cooking surface — and paired with a wider canopy and stronger airflow. Because they're suspended from the ceiling, island hoods also need to be anchored into joists or a dedicated structural frame, which makes getting the height right the first time especially important.
Why the Right Range Hood Height Matters
The recommended range isn't arbitrary — it's the window where the hood actually does its job. Miss it in either direction and performance drops.
Mounted Too High
This is the more common and more expensive mistake. When the hood sits too far above the cooktop, the rising column of smoke and grease has room to spread out and cool before it reaches the canopy, so much of it escapes into the room instead of into the filters. A gorgeous hood mounted up near the ceiling becomes décor rather than ventilation. If your hood runs on high and still leaves a haze over the stove, height is a prime suspect — the same root cause behind a lot of weak capture and a hood that won't pull smoke. And you can't simply crank up the CFM to fix it: airflow and placement have to work together.
Mounted Too Low
Too low creates different problems. The hood is exposed to more direct heat, which can damage the canopy, controls, and filters over time — a real concern above a high-BTU gas burner. It also collects grease faster, blocks your view of the back burners, and turns into something you knock your head on while cooking. The clearance minimums exist to keep the hood out of harm's way.
Other Factors That Affect Mounting Height
Once you know your baseline, a few real-world variables fine-tune the final number:
- Ceiling height: most wall-mount chimneys telescope to fit 8–10 foot ceilings; for 10–12 foot ceilings, confirm an extension kit is available. The goal is to keep the hood at the correct clearance — not to push it up to the ceiling just because the ceiling is tall.
- Cook height and comfort: taller cooks can go slightly higher within the recommended range for headroom, but never above it — comfort shouldn't cost you capture.
- Cooktop height from the floor: most cooktops sit about 36 inches off the floor. Factor that in so the finished hood height is comfortable to reach and see under.
- Cooking intensity and CFM: heavy searing, frying, or wok cooking benefits from higher airflow and a hood sized slightly wider than the cooktop, but CFM complements correct height — it doesn't replace it.
How to Measure and Get the Height Right
Getting it right is mostly about measuring from the correct points and trusting the manual:
- Measure from the cooktop surface to the bottom of the hood canopy. That gap is the clearance number every spec refers to.
- Confirm your model's stated range first. It drives your cabinet and duct layout, so lock it in before you plan anything else.
- Center on the cooktop, not the cabinet. A hood centered on cabinetry instead of the burners will miss part of the plume no matter how good the height is.
- Test before you finish. Run the fan on every speed and hold a tissue or a little smoke near the intake to confirm strong, even capture before you install the chimney cover.
Whether it's under a cabinet, on a wall, or over an island, the principle is the same: dial in the height within your model's range, size the hood to the cooktop, and vent it properly — and the hood will deliver what it promised for years.
Frequently Asked Questions
How high should a range hood be above the stove?
For most hoods, 24 to 30 inches above the cooking surface. Gas cooktops often go toward the higher end or above (up to about 36 inches) for flame clearance, electric and induction can sit a little lower, and island hoods are typically 30 to 36 inches. Always confirm your specific model's manual, since manufacturers set their own clearances.
Is 30 inches too high for a range hood?
No — 30 inches is within the recommended range for most hoods and is common for gas cooktops and island installations. If your hood is at 30 inches and still leaving smoke behind, the issue is usually undersized airflow or a hood narrower than the cooktop, not the height itself. For a low-heat electric cooktop, dropping toward 24 inches can improve capture.
Can a range hood be mounted too high?
Yes, and it's the most common height mistake. Mounted too high, the hood lets the smoke plume spread out and cool before it reaches the filters, so a lot of grease and smoke escapes into the room. Keep the hood within the manufacturer's clearance window rather than up near the ceiling.
What is the correct height for an island range hood?
Island hoods are usually installed 30 to 36 inches above the cooktop — slightly higher than under-cabinet or wall-mount hoods — because the cooking area is open on all sides and more exposed to cross-drafts. Pair the higher mount with a wider canopy and strong airflow, and anchor the hood securely to ceiling joists or a structural frame.
Does an induction cooktop need a different mounting height than gas?
It can be mounted a bit lower than gas because induction produces very little ambient heat and no open flame. But induction cooking still creates grease, steam, and odors, so the hood still needs to capture the full plume — treat it like an electric cooktop at around 24–30 inches and follow the model's manual.
How do I measure range hood installation height?
Measure the vertical distance from the surface of the cooktop up to the bottom edge of the hood canopy. That clearance is the number the manufacturer's spec refers to — not the distance to the top of the chimney or the cabinet.
