A range hood should be installed 20 to 30 inches above an electric or induction cooktop, and 24 to 36 inches above a gas stove. The exact height depends on your specific appliance, as installing it too high reduces smoke capture and too low poses a fire hazard.
When the hood is centered, it can effectively capture the rising heat and contaminants, preventing them from spreading throughout the kitchen. When the hood is not properly centered over the cooktop, it may not be able to effectively remove these pollutants, resulting in poor indoor air quality.
For indoor ranges, the standard mounting height is 28 to 36 inches from the cooktop to the bottom of the hood. Sticking to this window ensures safe clearance from the heat while maintaining optimal suction power to clear smoke and odors.
Yes, for optimal performance, your range hood should be wider than your cooktop. The standard rule of thumb is to choose a hood that is 6 inches wider than your cooking surface—extending 3 inches past the range on both sides.
Range hoods must typically be mounted between 24 to 36 inches above the cooking surface. For optimal safety and efficiency, the safe range is 24 to 30 inches for electric cooktops and 30 to 36 inches for gas cooktops.
Too high, and it may struggle to capture steam and odours effectively. The ideal mounting height depends on the type of rangehood and the kind of cooktop you're using. Most manufacturers recommend a clearance between 600mm and 750mm from the top of the cooktop to the underside of the rangehood.
In most residential kitchens, a standalone oven does not legally require a hood, but having proper ventilation is strongly recommended. While built-in ovens vent heat into the room naturally, a hood or exhaust fan removes smoke, grease, moisture, and cooking odors from your space.
30 inch range hoods cover 24” and 30” cooktops well, while 36” hoods cover 30” and 36” cooktops. We always recommend that, when possible, our customers buy hoods that are one size larger than their range. For example, if you have a 30” range, a 36 inch range hood is ideal.
The minimum distance between a cooktop and a range hood generally ranges from 20 to 30 inches, depending on the type of stove. Always check your specific model's installation manual, as manufacturer requirements and local building codes may supersede general guidelines.
No, range hoods do not need to be vented outside. If ductwork isn't an option, you can use a ductless (ventless) range hood. However, venting outside is highly recommended for optimal performance because it pulls smoke, grease, moisture, and heat directly out of your home.
Tall ceiling height opens up many great design possibilities, but it can complicate the range hood placement a bit. You might be tempted to install a wall mount hood higher than the 30'' to 36'' recommended above just to take up vertical space. That would be a mistake.
For a 36-inch cooktop, the ideal range hood size is 36 to 42 inches wide. While a standard 36-inch hood works perfectly for most setups, upgrading to a 42-inch hood is highly recommended if you frequently use high-heat methods like searing or stir-frying.
You may also notice poor suction if the fan blade is broken or the filters need replacing, or need to be unclogged. How Long Do Range Hoods Last? The lifespan of your range hood will be dependent on the individual model, quality, and use. Most range hoods last 12 to 18 years, about 15 years on average.
If you have an electric cooktop, range hoods should typically be 20–24 inches above the heat source. For gas cooktops, your range hood should be around 24–30 inches above the stove. Range hoods are a great way to complement your cooktop or range and can help clear the air while you cook.
A range hood should stick out deep enough to cover at least the front burners of your cooktop. For most standard 24-inch deep counters and stoves, an optimal hood depth of 18 to 22 inches is required to effectively capture steam, grease, and smoke.
Whether a range hood should touch the adjacent cabinets depends on the type of hood you are installing.
Range hood vent codes require hoods to vent directly outdoors using rigid, smooth-walled metal ducts. Key installation rules include a 24 to 36-inch mounting height above the cooktop, a minimum exhaust rate of 100 CFM, and an outdoor termination. Systems exceeding 400 CFM must feature interconnected makeup air systems.
The ideal distance between a range (or cooktop) and the range hood depends on your stove type, as recommended by the KitchenAid Guide on Range Hood Height:
Range hood clearances should generally fall between 24" and 36" above the cooking surface. The exact required distance depends on your specific range type (gas vs. electric), the hood's design, and the manufacturer's specific instructions.
When choosing between a 30-inch and 36-inch range hood, the golden rule is to go 6 inches wider than your cooktop (adding 3 inches of overlap on each side). If you have a standard 30-inch stove, a 36-inch hood is highly recommended for better smoke capture, aesthetic appeal, and keeping surrounding cabinets grease-free.
For a 30-inch cooktop, aim for 300–600 CFM, but for gas stoves or open-concept kitchens, go higher—800 to 900+ CFM is recommended.
No, a range hood does not have to be the exact same size as the stove, but it must be at least as wide as the cooking surface.
If you don't have a traditional range hood, you can manage smoke and odors with practical alternatives like reversible window fans, portable HEPA air filters, or ductless over-the-range microwaves. These solutions offer varying levels of air circulation, grease capture, and odor elimination.
If venting outside is not an option, a ductless range hood can be installed. This option uses a series of filters to trap grease and odors before recirculating the air back into the kitchen. While not as effective as venting outside, it is still a viable option for those without access to a duct system.
Commercial kitchen hoods are divided into two main categories based on what they are capturing. Type 1 hoods handle grease, smoke, and heavy-duty cooking, and require built-in fire suppression. Type 2 hoods manage only heat, steam, and moisture.
