How high should I position the range hood above the stove?

How High Should Your Hood Be Mounted

Every manufacturer will provide a recommended moun

Every manufacturer will provide a recommended mounting height for their hoods. But, the general rule of thumb is that range hoods should be mounted between 20-24 inches above electric or induction stoves. And between 24-30 inches above a gas range. 

Does A Hood’s Size Affect The Mounting Height?

Choosing the right size range hood is determined by the size of your cooktop. The most important thing here is that your hood is at least as wide as your range, although a hood that’s 6-inches wider than your cooktop is ideal.

This creates a larger capture area where smoke and fumes are effectively removed by the hood. But, the width and depth of a hood do not change how high it should be mounted.

Does A Hood’s Power Affect The Mounting Height?

For a majority of residential kitchen hoods, the mounting height will fall between the common 20-30 inch mounting height.

However, if you start looking at high-powered or professional range hoods, you may come across slightly higher recommended mounting heights. Often somewhere between 28-36 inches above the cooktop. 

The extra clearance above your stove will take into account the increased suction power of those particular hoods. Having them raised slightly higher can create a larger and more efficient capture area to remove more smoke and fumes.

What Size Should a Vent Hood cover Be?

If you are buying a new vent hood for your kitchen there are some guidelines for how large it should be. The size depends on your kitchen layout and whether you have an island cooktop or your stove is on an interior wall or exterior wall. It also depends on the width of your range.

As a rule of thumb you want your range hood to be at least as wide as your range or cooktop. With that said, they come in pretty standard sizes. Most range hoods come in 30 inch and 36 inch widths. Most ranges come in 30 inch and 36 inch sizes.

If you have a 36 inch range, you need at LEAST a 36 inch vent hood. If you have a 30 inch oven you can use a 30 inch vent hood. Get the size that is at least as large as your range.

Range Hood Height, Surface Area Considerations & More

As a general rule, calculate 100 cfm for every linear foot of cooking surface. For pro-style ranges, the formula is 100 cfm for every 10,000 BTUs your appliance puts out. Other factors come into play as well. For every 3 inches a hood exceeds the suggested height above the cooktop, add 100 cfm.

Island hoods require extra cfm to compensate for cross drafts, so calculate 150 cfm per linear foot for conventional cooktops; add an additional 100 cfm to the pro-range estimate. And consider how you cook. If you rarely grill or stir-fry at high heat, you may be able to go with a lower cfm than recommended.

vent hood styles

Choosing the right kitchen hood can be an important design choice. There are lots of different vent hood styles that vary depending on where they go in your kitchen. For the sake of comparison, I’m showing prices for the 30″ size below.

Wall mount range hoods- This is the most common ty
  • Wall mount range hoods- This is the most common type of vent hood. The prices on these can be as low as $139 from Home Depot or as high as several thousand.
  • Island range hoods – These are more expensive. This island mount range hood from Home Depot is $377.
  • Cabinet range hoods – These mount to the bottom of an existing cabinet. They are not the type that are going in most newly remodeled kitchens, but if you are replacing an old one they are very inexpensive. This under cabin range hood from Home Depot is only $66
  • Microwave range hoods- If you have a microwave directly over your range, you can use this type of vent, but these are not ideal in terms of best performance. If you have limited space, they can be a good option.
  • Custom range hoods – Thanks to Joanna Gaines vent hoods have become integral in kitchen design. There are a lot of people who are building their own range hood covers to go around the basic mechanical vent. Here’s a really cool farmhouse DIY vent hood that is built around a standard “insert range hood”. They sell the inserts like this one at Home Depot and they are the mechanical portion of the range hood. Keep reading for suggestions on where to buy a custom cover for your range vent.

What happens if I mount my hood too close to my cooktop?

Your hood may become damaged

Ranges produce a lot of heat. That heat may damage the outside of your stainless steel range hood and the circuitry on the inside of the hood. If exposed to intense heat for too long, this damage may be irreparable.

If you mount your hood too close to the cooktop, be extra cautious about what you are cooking and how often you are cooking.

You may start a fire

If your hood is too close to your cooktop, the intense heat may start a fire in your kitchen, which may damage your range, cabinetry, and other surrounding areas. This could be a big hit to your finances because you would need to replace your hood and repair the surrounding damage in their kitchen.

You will have to clean your vent hood more frequently

Your vent hood will be closer to the cooking surface which means that the grease and dirt from your cooking will stick to surrounding surfaces. You’ll need to clean the stainless steel outside of your hood more frequently, probably every couple of weeks as opposed to monthly.

The longevity of your motor is reduced

A hood too close to the cooktop puts a lot of strain on the blower and other internal components. All of the intense heat and fumes need to be filtered out very quickly, which can cause your motor to become overworked.

Ventilation Hoods to Avoid

Downdrafts

Ventilation mistakes have been a big part of our webinars. Our “Appliances You Should Never Buy” webinar featured downdrafts as the number one appliance you should avoid.

Downdrafts reverse gravity and have zero capture area. Most of the power burners are now on the front of ranges, and yet a downdraft is behind the range.

Over-the-range microwaves centralize your cooking. I love them as a concept, yet their CFM is only 310 with little capture area.

You may want to think about a hood and placing the microwave elsewhere.

Cirrus Hoods

These hoods are new, Italian-inspired, and beautiful. However, by placing the hood in the ceiling, some of the smoke will dissipate before being extracted.

If you cook a lot, then I would consider other options.

How High Should Range Hood be from the Stove: FAQs

Do you have to have a range hood above a stove?

Yes! You should have a range hood over the stoves in your kitchens, even if it is not legally required, but for cleanliness and your kitchens’ long life to prevent dust, steam, moisture, and heat.

How much clearance do you need for a range hood?

In most US states, the minimum height clearance needed by the building’s 18 inches is considered the average height from the top of the stove to the bottom of the range hood.

Do range hoods have to go to the ceiling?

If you install a vented hood on the wall or under the cabinet, the wires will run behind the outer walls. But when range hoods have to go to the ceilings, the ducts should run above the ceilings. Moreover, the ductless range hoods can be mounted easily anywhere you want, which comes in your budget easily.

Size of Cooking Range

The size of the cooking range is a major factor to consider while determining the installation height for your range hood. The more expansive the cooking range, the more the steam and grease produced during cooking are likely to expand and spread over a large surface area. This will, in turn, affect the efficiency of the range hood depending on the installation height.

How do you mount an under cabinet hood?

Mounting your under cabinet hood is very similar to mounting your wall hood. Here’s what you will need:

Step 1 is the same as mounting your wall hood. Her

Step 1 is the same as mounting your wall hood. Here are the instructions again below:

Like with the wall hood installation, for Step 2 y

Like with the wall hood installation, for Step 2 you are going to hang the hood on the mounting screws and support it by drilling into studs in the back of it.

If the slots in the back of the range hood do not match up with the studs, you can drill through the back of your range hood.

Your ductwork can be taped to the top of the range hood using airtight aluminum tape. If you’re unsure about what size duct you need, check out our article on range hood duct sizes.

What is an ideal height for the range hood

Manufacturers provide the precise size of the range hood within the instructions supplied with the hood. Once you have purchased the hood, begin to install it between 20”-24 inches, just over the cooking surface. If it’s situated on top of a gas cooker, the distance must be 25″ and 30″, unless stated otherwise. It is not recommended to install it at a height below the minimum required as it is governed by numerous safety tests. Also, you should not exceed the upper limit since it could impact the performance of your hood.

The height of your range hood’s height is highly vital as there are fires on a cooktop. If you use the incorrect size, having it too close cook top causes fire, resulting in an unexpected loss. But, if you’re making use of an electric cooker, there aren’t any flames to be concerned about, so the distance and height could be considerably smaller.

Conclusion

The correct installation height of your range hood depends on the type of range you have. For maximum efficiency in your kitchen, remember these recommended height ranges:

 

  • If you have a gas range, install your range hood 24 to 36 inches above your cooktop. 
  • If you have an electric range, install your range hood 20 to 24 inches above your cooktop.
  • If you have an outdoor grill, install your range hood 36 to 42 inches above your cooktop.

 

Besides the type of range, other factors in choosing a range hood include the cubic feet per minute and your kitchen layout.

Considering these criteria carefully will help you choose the best range hood for your specific kitchen needs.

Good luck installing your brand new range hood! You should be good to go as long as you follow all of our instructions and essential pointers.
