The standard mounting height is 24 to 30 inches above the cooktop surface

Most range hoods work best when mounted 24 to 30 inches above your cooktop. This distance lets the hood capture steam and cooking odors before they spread through your kitchen, while keeping the hood low enough that it doesn't interfere with overhead cabinets or your sightline while you cook.

The exact height depends on three things: the type of cooktop you have, the hood's design, and your kitchen layout. A gas cooktop typically needs the hood mounted closer to 30 inches because gas flames produce more heat and smoke. An electric cooktop can work at 24 inches. If your hood has a downdraft design (pulling air down instead of up), you may need to mount it lower, around 20 to 24 inches.

Check your hood's manual first — manufacturers often specify a range based on their model's suction power and design. If you don't have the manual, the 24 to 30 inch range is the safe middle ground used by most kitchen designers and building codes.

Key Takeaways

  • Standard mounting height is 24 to 30 inches above the cooktop surface, measured from the cooktop to the bottom of the hood.
  • Gas cooktops usually need the hood mounted closer to 30 inches because they produce more heat and smoke than electric cooktops.
  • Your range hood's manual will specify the manufacturer's recommended height, which should take priority over general guidelines.
  • Mounting too high reduces the hood's ability to capture steam and odors; mounting too low can create a safety hazard or block your view while cooking.
  • Downdraft hoods and island hoods may have different height requirements than standard under-cabinet models.

Why the 24 to 30 inch range matters

The distance between your cooktop and hood controls how much of the cooking steam and smoke the hood actually captures. When the hood is too high, rising heat and odor disperse into the kitchen before reaching the hood's intake. When it's too low, the hood can block your view of the burners, and you risk bumping your head or a tall pot lid hitting the hood during cooking.

The 24 to 30 inch range is the zone where most hoods achieve their rated suction power. Manufacturers test their hoods at these distances, so the CFM (cubic feet per minute) rating you see on the box assumes this mounting height. Mount it higher and the hood's real-world performance drops, sometimes significantly.

Gas cooktops versus electric cooktops

Gas cooktops produce more heat and visible smoke than electric cooktops, so they benefit from a hood mounted at the higher end of the range — closer to 30 inches. The extra height still captures the heat and smoke effectively because gas flames are more vigorous and produce a stronger updraft.

Electric cooktops generate less visible smoke and a gentler heat pattern, so a hood at 24 to 26 inches works well. If you have a smooth-top electric cooktop, you can safely mount the hood at 24 inches without losing much capture efficiency.

Downdraft and island hood heights

Downdraft hoods pull air downward through a vent in the cooktop or countertop, rather than upward into a wall or ceiling duct. These hoods often need to be mounted lower — sometimes 18 to 24 inches — because the downward pull is less powerful than an upward-venting hood. Check your downdraft hood's manual for its specific requirement.

Island hoods (mounted above a cooktop in the middle of the kitchen) follow the same 24 to 30 inch rule as wall-mounted hoods, but they're more visible, so many homeowners prefer to mount them at the higher end to keep sightlines clear. An island hood at 28 to 30 inches looks less intrusive while still capturing cooking odors effectively.

Measuring and marking before installation

Measure from the cooktop surface straight up to where the bottom of the hood will sit. Use a tape measure and a level to mark the wall or cabinet where the hood's mounting bracket will go. Mark both sides so the hood hangs straight.

If you're replacing an existing hood, the mounting holes may already be in place. If they're at the wrong height, you'll need to patch the old holes and drill new ones. For a new installation, measure twice and mark lightly with pencil before drilling, so you can adjust if needed.

Clearance and safety considerations

Make sure the hood doesn't interfere with upper cabinets or a soffit above the cooktop. Most hoods are 6 to 8 inches deep, so measure from the back of the cooktop to the wall to confirm there's enough space. If you have cabinets directly above the cooktop, the hood's top edge should sit at least 2 inches below the cabinet bottom.

Keep the hood away from windows or exterior walls if possible, because ductwork running to the outside is harder to seal and can let cold air back in. If you must vent through an exterior wall, use a damper in the ductwork to prevent backflow.

When your kitchen layout doesn't fit the standard

Some kitchens have low ceilings, tall cabinets, or unusual layouts that make the standard 24 to 30 inch height impossible. If your ceiling is too low, consider a low-profile or slim-line hood, which is shallower and can work at a slightly lower height. If you have tall cabinets above the cooktop, you may need to mount the hood higher than 30 inches — in that case, choose a hood with higher CFM rating to compensate for the extra distance.

If standard mounting won't work, a downdraft hood or a recirculating hood (which filters air and returns it to the kitchen instead of venting outside) may be your best option. Recirculating hoods don't need ductwork, so height is less critical, though they're less effective at removing moisture and odors than vented hoods.

Frequently Asked Questions

Can I mount my range hood higher than 30 inches?

You can, but the hood's suction power will be less effective because steam and smoke will disperse before reaching the intake. If your kitchen layout requires a higher mount, choose a hood with a higher CFM rating to compensate. Check your hood's manual to see if the manufacturer lists performance at heights above 30 inches.

What if I have a very low ceiling?

Look for a low-profile or slim-line hood, which is designed for tight spaces and can work at heights as low as 20 inches. Alternatively, a downdraft hood pulls air down through the cooktop and doesn't need vertical clearance above it. Both options are less powerful than standard hoods, so choose one rated for your cooktop size.

Does the hood height change if I have a gas range with a griddle or wok?

Yes. Griddles and woks produce more heat and steam than standard burners, so mount the hood at the higher end of the range — 28 to 30 inches — to capture the extra moisture and odor. If you use a wok frequently, consider a hood with a higher CFM rating as well.

Should I mount the hood higher if I have an open kitchen?

Not necessarily. The 24 to 30 inch range still applies because it's based on the hood's suction power, not the room layout. However, in an open kitchen, cooking odors spread faster, so you may want to mount the hood at the lower end (24 to 26 inches) to capture them more aggressively before they reach the living area.

What if my cooktop is recessed into the counter?

Measure from the highest point of the cooktop surface — usually the rim of the largest burner or the edge of the cooking surface — straight up to the hood. If your cooktop sits below counter level, you may need to mount the hood slightly lower to maintain the 24 to 30 inch distance from the actual cooking surface.
