Range Hood Installation Height: Clearance Above Cooktop by Hood Type

What Is the Standard Range Hood Installation Height?

The typical clearance between a cooktop and the bottom of a range hood is 24 to 30 inches for electric stoves and 24 to 30 inches for gas models, though manufacturers often specify a narrower range. For example, many brands recommend 24 to 30 inches for electric cooktops and 24 to 30 inches for gas burners, with a common starting point of 27 inches. This measurement is taken from the cooking surface to the lowest point of the hood, which is usually the underside or the grease filter.

However, the standard height is not a universal rule. Local building codes may impose minimums, and some high-output gas ranges produce more heat and require a taller clearance. Always check the owner’s manual for your specific hood model, as the manufacturer’s specification overrides generic advice. If the manual is missing, measure the distance from the cooktop to the ceiling and factor in the hood’s duct collar location to avoid cutting a duct run that is too short or too long.

The clearance also affects performance. A hood mounted too high loses capture efficiency, allowing smoke and grease to escape into the kitchen. Mounted too low, it becomes a safety hazard and can obstruct tall pots. The 24–30 inch band is a balance between fire safety, ergonomics, and ventilation effectiveness, but you must adjust for the cooktop type and the hood’s cubic feet per minute (CFM) rating.

Why Does the Recommended Clearance Differ Between Electric and Gas Cooktops?

Electric cooktops, including induction and radiant models, generate heat directly on the pan surface, with less upward heat plume compared to gas. As a result, you can often mount the hood slightly lower—around 24 to 27 inches—because there is less risk of the hood’s surface reaching high temperatures. Lower mounting also improves capture of steam and cooking odors, which rise more slowly from electric elements.

Gas cooktops produce open flames and significant convection heat, which can damage the hood’s finish or ignite grease if the hood is too close. The typical recommendation for gas is 24 to 30 inches, but many manufacturers require a minimum of 30 inches for units over 60,000 BTU or for ranges with a high-output burner. Some local codes adopt the 30-inch minimum for all gas installations, so verify with your building department before cutting any holes.

Induction cooktops, while electric, heat pans quickly but the surface stays cooler than radiant. You can still follow the electric range guideline of 24 to 30 inches. However, if your induction cooktop has a bridge element or is wider than 30 inches, increase the clearance by 1 to 2 inches to account for the larger heat plume. Always prioritize the manufacturer’s data, as they test for both performance and safety.

How High Should a Ducted Range Hood Be Above a Gas Stove?

For a ducted range hood above a gas stove, the recommended height is typically 24 to 30 inches, but 30 inches is the most common minimum for gas due to fire codes. If your gas range has a high BTU output (above 60,000 BTU total), consider mounting at 30 to 36 inches to prevent heat damage. The exact figure depends on the hood’s CFM; a higher CFM can pull smoke from a greater distance, so a slightly taller mount still works effectively.

Measure from the burner grate or the highest point of the cooktop surface, not the base of the range. Use a level to mark a reference line on the wall at the chosen height, then subtract the hood’s internal depth to position the mounting brackets. For a ducted hood, the duct run’s vertical rise also matters—keep it as short and straight as possible, with no more than two 90-degree elbows, to maintain airflow. The height directly impacts static pressure, so a longer run may require a higher CFM to compensate.

A practical test: turn the hood on to its highest speed and hold a piece of paper near the burner. If the paper lifts and stays, the height is within a functional range. If not, lower the hood by 1 to 2 inches and retest. Remember that gas stoves produce moisture and combustion byproducts, so the hood should be vented outdoors, not recirculated, to comply with most building codes.

What Is the Best Height for a Ductless or Recirculating Hood?

Ductless hoods, which filter air through charcoal and recirculate it, have a similar recommended height of 24 to 30 inches above the cooktop. However, because they do not exhaust outdoors, the capture distance is more critical. Mounting at the lower end (24–27 inches) improves capture of steam and odors, but you must ensure the hood does not interfere with tall cookware or your line of sight while cooking.

One key difference is that ductless hoods rely on the charcoal filter to trap grease and odors, so the filter’s efficiency drops if the hood is mounted too high. The blower has to work harder to pull air through the filter, reducing airflow and increasing noise. For best results, check the manufacturer’s height range—some ductless models specify a minimum of 27 inches to avoid heat exposure from the cooktop, even though there is no open flame.

Also consider the ceiling height. In a kitchen with a 9-foot ceiling, a ductless hood mounted at 30 inches leaves 6 feet of clearance to the ceiling, which is fine. But in a low-ceiling kitchen (8 feet), a 30-inch mount may place the hood too close to the ceiling, limiting access for filter changes. In such cases, opt for a slim or telescoping model that can be mounted at 24 inches without looking oversized.

How Do I Measure for a Wall-Mount vs. Island Hood Clearance?

For a wall-mount hood, the clearance is measured from the cooktop to the hood’s bottom edge, typically 24 to 30 inches. But the mounting height also depends on the hood’s width relative to the cooktop. A good rule: the hood should be at least as wide as the cooktop, and for islands, it should extend 3 inches beyond each side of the cooking surface. Measure from the highest burner to the lowest point of the hood, excluding any protruding knobs.

Island hoods are mounted to the ceiling, so the height range is often 30 to 36 inches above the cooktop, because the hood is not attached to a wall and must clear the island’s overhang. The ceiling mount introduces additional structural considerations—the duct must run through the ceiling, and the hood’s weight requires a solid support beam. Always check the manufacturer’s installation manual for the exact height and use a stud finder to locate ceiling joists before drilling.

For both types, mark the centerline of the cooktop on the wall or ceiling, then measure the hood’s mounting bracket placement. Use a template if provided, and double-check that the duct collar aligns with the vent opening. A common mistake is forgetting to account for the hood’s depth; a deep canopy may need a higher mount to avoid head bumps. If you are shorter than average (under 5’6”), consider mounting at 28 inches for comfortable access to controls, but never below the minimum clearance specified for your cooktop.

What Are the Safety and Code Requirements for Hood Clearance?

Building codes, such as the International Residential Code (IRC), often require a minimum clearance of 24 inches for electric cooktops and 30 inches for gas, but this varies by jurisdiction. Some municipalities adopt the manufacturer’s recommendations as code, so always verify with your local building department. Non-compliance can lead to failed inspections or, worse, fire hazards, especially if the hood is too close to a combustible surface.

In addition to vertical clearance, consider horizontal clearance. The hood should not be positioned where it can be struck by a swinging pot handle or where steam can condense on electrical components. For gas ranges, maintain at least 30 inches between the cooking surface and any combustible material, including the hood’s ductwork. If you have a microwave-hood combo, the installation manual will specify a different height, often 18 to 24 inches above the cooktop, which is lower than standard hoods.

Always hire a licensed electrician for the electrical connection, as this is a separate task from ducting. The electrical wiring should be on a dedicated circuit, and the hood must be grounded. For ducted installations, use smooth metal ductwork (not flexible plastic) to reduce fire risk and improve airflow. If you are unsure about any measurement, consult a professional—it is cheaper than correcting a mistake after drywall is installed.
