Standard hood height is 24 to 30 inches above the cooking surface

Most building codes and appliance manufacturers recommend mounting your range hood between 24 and 30 inches above the stovetop. This distance balances two competing needs: the hood must be close enough to capture steam and cooking odors before they spread through your kitchen, but far enough away that it does not interfere with tall cookware or your head when you are cooking.

The exact distance depends on the type of hood you have. A ducted hood (one that vents outside through ductwork) typically sits at 24 to 30 inches. An under-cabinet hood mounted directly to the cabinet above your range usually lands at the lower end of that range. An island hood hanging from the ceiling over a cooktop in the middle of the room often sits 28 to 36 inches high because it has more room to work and needs to clear sightlines across the kitchen.

Check the manual that came with your hood—it will specify the manufacturer's recommended distance. If you no longer have the manual, search the model number on the manufacturer's website or call their customer service line.

Key Takeaways

  • Most range hoods mount 24 to 30 inches above the cooking surface, measured from the stovetop to the bottom of the hood.
  • Under-cabinet hoods typically sit closer to 24 inches, while island hoods often sit 28 to 36 inches high.
  • Too low and the hood blocks your view and can interfere with tall pots; too high and it cannot capture steam and odors effectively.
  • Your hood's manual contains the manufacturer's specific recommendation for your model.

Why the 24 to 30 inch range matters

At 24 inches, the hood is close enough to pull steam and grease-laden air directly upward before it spreads across your cabinets and walls. This distance works well for most home cooks because it sits above the tallest cookware you are likely to use—a stockpot or pasta pot rarely exceeds 12 inches in height, leaving a comfortable margin.

At 30 inches, you gain more headroom and a clearer view of what is cooking, but the hood's capture efficiency drops. Air that rises from the stovetop spreads out as it climbs, so a hood mounted higher has to work harder to pull it in. If you go beyond 30 inches without a very powerful motor, you will notice cooking smells lingering in the kitchen longer than they should.

The sweet spot for most kitchens is 28 inches. This height gives you enough clearance for normal cooking while keeping capture efficiency high.

How to measure and mark the correct height

Measure from the top surface of your stovetop (not the backsplash behind it) straight up to where the bottom edge of the hood will sit. Use a tape measure and a level to mark the height on the wall or cabinet where the hood will mount.

If you are installing an under-cabinet hood, measure from the stovetop to the bottom of the cabinet first. Most under-cabinet hoods are designed to fit in a standard 12-inch-deep cabinet space, which naturally places them in the 24 to 30 inch range. If your cabinet is deeper or shallower than standard, you may need a hood designed for that depth.

For an island hood, measure from the stovetop to the ceiling, then work backward. Most island hoods need at least 12 inches of clearance above them for proper ventilation, so if your ceiling is 8 feet high, you would mount the hood no higher than 72 inches minus 12 inches, or 60 inches from the floor—which puts the bottom of the hood around 30 to 36 inches above the cooktop.

What happens if your hood is too low

A hood mounted below 24 inches will block your view of the stovetop and can be a safety hazard. You may hit your head or a tall pot lid against it. Steam and heat rising from the burners can also damage the hood's motor and filters faster than normal, shortening the hood's lifespan.

If your kitchen layout forces the hood lower than 24 inches—for example, if you have a very low cabinet or a sloped ceiling—talk to a kitchen designer or contractor about alternatives. A downdraft hood pulls air down and backward through a duct in the floor or wall, rather than up, and can work in tight spaces. A pop-up hood rises from the countertop only when in use and retracts when off, saving headroom.

What happens if your hood is too high

A hood mounted above 30 inches will not capture cooking odors and steam as effectively, especially if the motor is not very powerful. You will notice smells lingering in the kitchen, grease settling on cabinets farther from the stove, and steam fogging up windows or light fixtures across the room.

If your ceiling is very high or your cooktop is on an island far from any wall, a standard hood may not work well no matter where you mount it. In that case, a high-powered island hood with a larger capture area and a stronger motor can help. Some island hoods are rated for 600 to 1200 cubic feet per minute (CFM) of airflow, compared to 300 to 500 CFM for a typical under-cabinet hood. The higher the CFM, the better it can pull air from a distance.

Clearance and safety considerations

Beyond the 24 to 30 inch rule, check that your hood does not sit directly above a gas burner's flame. If you have a gas range, the hood should be at least 24 inches above the highest point the flame can reach. Electric ranges do not produce open flame, so this is less of a concern, but the same 24 to 30 inch distance still applies.

Make sure the hood does not block any windows, light fixtures, or cabinet doors above it. If you are installing a new hood and your kitchen layout is tight, measure the hood's width and depth before you buy it. An oversized hood can look cramped and may not fit between cabinets or under a soffit.

If your hood vents outside through ductwork, the duct should slope slightly upward as it runs to the exterior wall or roof. This helps condensation drain back into the hood rather than pooling in the duct. A professional installer will handle this, but if you are doing it yourself, keep the slope gentle—about 1/4 inch per foot of duct run.

Adjusting an existing hood that is mounted wrong

If your hood is already installed and you think it is too high or too low, you can often remount it. Turn off the power at the breaker, disconnect the ductwork and electrical connection, and unbolt the hood from the wall or cabinet. Patch the old holes, measure the new height, and drill new mounting holes. Reconnect the ductwork and power, and test the hood to make sure it is venting properly.

This is straightforward if you are comfortable with basic tools and electrical work. If you are not, or if your hood is hardwired (not plugged in), hire a licensed electrician or appliance installer. Improper installation can damage the hood, create fire hazards, or void the warranty.

Frequently Asked Questions

Can I mount my hood higher than 30 inches if I have a powerful motor?

A more powerful motor helps, but it cannot fully overcome the physics of distance. Air spreads out as it rises, so a hood at 36 inches will always capture less efficiently than one at 28 inches, even with a 1200 CFM motor. If your ceiling is very high, a wider hood or a downdraft system may work better than mounting a standard hood higher.

Does the hood need to be the same width as the stovetop?

No, but it should be at least as wide as the stovetop, and ideally 3 to 6 inches wider on each side. A hood that is narrower than the stove will miss some of the rising steam and odors. A hood that is much wider than the stove looks out of proportion and may not fit your cabinet space.

What if my range is on an island and I cannot mount a hood above it?

You have a few options. A downdraft hood pulls air down through a duct in the floor. A pop-up hood rises only when cooking. Or you can install a wall-mounted hood on the nearest wall, though it will be less effective than one directly above the cooktop. Some building codes allow a range on an island without a hood if the kitchen has good overall ventilation, but check your local code first.

Should the hood be centered over the range?

Yes. Center the hood side to side over the stovetop so it captures steam evenly from all burners. If the hood is off to one side, burners on the opposite side will not vent as well, and odors will spread across the kitchen.

Can I install a hood myself, or do I need a professional?

If the hood is plugged into an outlet and vents through existing ductwork, you may be able to install it yourself. If it requires hardwiring, new ductwork, or venting through a wall or roof, hire a licensed electrician and HVAC contractor. Improper installation can create fire hazards and void the warranty.
