What Is The Standard Of Kitchen Hood Sizes?

The size of a kitchen hood is important for both the safety and function of the appliance.

Kitchen hoods are designed to remove cooking odors, smoke, grease, steam, and humidity from kitchens.

The sizing standard for kitchen exhaust fans is based on how many cubic feet per minute (CFM) they can move.

Do you know the standard of kitchen hood sizes?

Measure the width of the area over the range or cooktop. Range hoods often come in 24″, 30″ or 36″ widths. The hood should be exactly as wide as the cooking surface.

Kitchen hoods are available in many different sizes. When you make a purchase, you must consider the size of your kitchen and the location where your new appliance will sit. For example, if you have an extremely small kitchen, installing a large commercial-grade hood may take up too much space and make the room feel even smaller.

If your cooking area is rather generous, a 36″ or 48″ island hood would work nicely.

The standard for commercial use is 72″.

If you plan on cooking gourmet meals at home with friends and family members seated all-around your stovetop then get a 60″ or 72″ island model to get ample suction power above your range cooktop.

In terms of color, variety is the spice of life. While white is still considered standard, you can find island brands in black or stainless steel. Why not mix it up with a bronze or copper color?

What are the features to look for in a kitchen hood?

Let’s be honest – no one wants to clean their vents after every use. This is why good air suction power should be at the top of your list when shopping for an island range hood.

To maximize airflow, choose models that feature high-powered blowers and filters designed to trap grease particles before they even make it into your ducts. The height of your ceiling will also affect how well air moves through the vents so keep this in mind as you shop around for an island unit.

If you’re a serious baker, look for a range hood with variable speeds and a booster feature that kicks the blower into high gear when you need to fan out your cake batter quickly. This will eliminate odors and smoke before they accumulate in the kitchen.

Stainless steel fans are best because the metal is non-reactive and does not rust or corrode as typical propeller blades do. Some island brands feature touchless controls that allow you to adjust speed settings without having to actually touch any buttons on the unit which is nice if you happen to be wearing dirty hands after cooking up something delicious!

What size should I buy?

This all depends on how much power it takes to suck the smoke from your stovetop. If you are cooking on a high BTU burner that is at least 12,000 to 15,000 BTUs then you need one that can keep up with the demand. A standard size island range hood is 36 inches wide. Island ranges are more generous but if you have an older home make sure it will fit through your doorway!

For commercial needs, look for an island model between 48″ and 54″. Why only 3 feet of width? Many restaurants have 10′ ceilings so anything bigger would be ridiculous unless they were trying to connect two buildings together or had truly gigantic equipment running on their stovetops.

Choosing the right ceiling height is very important as well because you want airflow throughout your entire kitchen no matter how big or small it is. For an island range hood, 36″ or 42″ should do the trick.

What are the types of kitchen hoods available?

Standard Island Range Hoods are the most widely used in kitchens today. They typically have a depth of 24 inches to ensure they fit properly underneath cabinets and provide proper air suction no matter what brand you chose for your kitchen.

These are typically used in residential homes but can be commercial grade depending on use. Some people will prefer this style over other styles because they give off the same look like your current cabinets without taking them away!

The only major difference is that standard models cover up to 30% to 50% less space than other types. For example, if you did not require a kitchen island and had a standard range hood with a 36″ width, you would need an area that is at least 45″ to cover the same space.

For example, if you did not require a kitchen island and had a standard range hood with a 36″ width, you would need an area that is at least 45″ to cover the same space. Island Mounted Range Hoods provide ventilation for your entire kitchen by drawing air from above. They are 24 inches deep just like their counter-top counterparts but typically require less space than other models because they do not require clearance beneath them since they mount directly to the ceiling or wall above.

How do you measure a kitchen hood?

1. The length of the kitchen exhaust hood is measured by standing at one end and joining your fingertips of both hands together to draw a straight line from end to end (without the fan on, unless it is recessed).
2. Measure the height of the kitchen vent hood beginning at ground level and measuring to top of the fan motor or factory-installed blower wheel. If this measurement exceeds 32″, we recommend adding an additional 18″ to your measurement for overall height and stability (i.e., if blade height exceeds 48″, add 27″).
3. Width: This will be determined by how many appliances you plan on exhausting into it. Generally, if you only plan on exhausting one appliance, allow 24-36 inches for the installation of the hood. For every additional appliance you exhaust into the kitchen hood, add 6-12 inches to width measurement.
4. Depth: This will be determined by the depth of your cabinets above the stovetop locations. Standard cabinet depth is 24 inches deep with 30″ being more common in-stock cabinetry used today. If no standard exists, measure the distance from the back wall to the front edge over all cabinet positions under consideration for installation — this is your depth requirement. Add 2-6 inches for clearance behind fan/motor and 1-2 inches if recessed for a test run before finalizing specifications.
5. Measure height(s) and width(s) at top of counter – do not include base cabinets in measurements.
6. If you plan on exhausting into a wall or under counter, add the depth of one cabinet to your total depth requirement OR allow for 34-44 inches from the rear wall to the front edge of the hood.
7. The outside dimensions of the hood are more critical than the inside dimensions due to clearances required at installation and in use: A general rule is 1″ clearance per inch width with 4-6″ in back and side and 2-4″ above depending on the type, brand and/or style of venting hood selected. You will need this space for maintenance access or removal of grease filters, etc., so do not place appliances too close to kitchen exhaust system openings. Allowances also are made for drip pans as well as the width of the range/cooktop as measured from front to back. In determining your appliance measurements, use a flexible measuring tape and measure appliances at their widest points – do not pull the tape tightly around corners!
8. For wall or under-counter installation: Make additional measurements from the bottom of counter to the floor for this dimension. Note that most residential construction is not plumb, so you will have to allow some amount of space between the hood top and underside of cabinets for stability (1-2″ minimum). This can be accomplished by placing a spacer between the fan housing and ceiling joists above; any gap below must be sealed with caulk or similar sealant.
9. Cabinet Depth: Allow sufficient depth for proper installation of cabinets above the hood with a minimum cabinet depth of 24 inches. It is recommended to have a minimum of 30″ deep cabinets for most residential use as this allows proper installation and maintenance access as well as greater storage space beneath.
10. Check widths with range, cooktop, or island installed before completing your order! If you plan on exhausting into a wall or under counter, add this dimension to the total depth requirement OR allow for 34-44 inches from the rear wall to front edge of the hood. Allow another 4-6″ for recessing if required by any appliances being exhausted into the structure above; do not forget 2-4″ above if recessed (furthest distance from the ceiling) and 2-6″ side clearance for fan/motor.

You will need to provide us with the following information when placing an order:

The brand, style, and model number of the appliance(s) you are exhausting into your kitchen hood system.

We also need measurements in inches for width, depth (from the cabinet above to floor), top height at the front counter edge, bottom height at floor or cabinet bottom, center back height from ceiling to bottom of fan housing).

These dimensions should be measured with the appliance(s) installed but without filters/lamps in place. If any appliances being exhausted have venting that comes up through floors or walls, measures must be provided. For wall or under-counter installation: Make additional measurements from the bottom of counter to the floor for this dimension

.A detailed drawing showing dimensions of the area above the hood, below the cabinet, and around appliances to be exhausted. Allow for proper clearance or recessing depending on the desired installation. You may also want to include drawings for any other areas where you intend ventilation (e.g., garage).

For under-counter installation:

Measure the height(s) at top of counter – do not include base cabinets in measurements — while adding 2 to 6 inches if the fan needs to be ‘recessed’ so that all front edges are flush with the counter surface. Remember, this will allow us to provide clearances, etc., during installation.

Please indicate if you are planning to exhaust into a wall or cabinet above – note that you will need at least one inch of free space between the top of your cabinet and the bottom of our fan housing. If recessing into the wall or cabinet, please provide dimensions at the top, middle and bottom; also indicate where any ‘hardware’ (e.g., register openings) will be located in relation to the bottom of the hood.

Please specify if you plan on flanking (exhausting through two separate side cabinets) or centering your venting hood – this allows us to provide proper dimensions for installation.

1. Lack of ventilation throughout the home is a cause of major concern when it comes to indoor air quality in homes with forced-air heating/cooling systems. According to the EPA, carbon monoxide levels can reach 1000 times normal levels when cooking on a gas stove.
2. A recirculating hood or range hood is an effective solution to address this problem and provides indoor air quality benefits of removing greasy, steamy, smokey, and other contaminated vapors from the kitchen.
3. This type of ventilation system has been used in Europe for many years but can be more difficult to install in North American homes. It uses an external fan unit that pulls air from inside your home through a ducting system underneath your kitchen countertop which then goes back up into the room above your range, cooktop or wall ovens in a circular motion in order to filter out any fumes or odors before going back outside through the roof venting. The fan unit simply needs to be plugged into a power outlet. The hood usually has an LED light that comes on, but the fan unit operates automatically when sensing smoke or steam in the air – it can sense heat in a range hood by means of a thermal detector.
4. Most recirculating kitchen vents allow enough venting for two standard-size countertop stoves or one oversized range hood with total exhaust draw up to 220 cfm (cubic foot per minute). However, small microwaves and toaster ovens may not exhaust enough air to activate the fan unit, so make sure it is sized properly before buying the product. In most cases, you need at least 15 amps of dedicated circuit wiring if going through wall surfaces for maximum performance.
5. The fan unit needs to be kept a minimum of 12 inches away from any wall or cabinet surface – it cannot have any direct contact with the countertop due to extreme heat. There should also be a space at least 8-12″ wide between the range/cooktop and the underside of a wall-mounted cabinet above – this creates the necessary circulation room for efficient ventilation.
6. You will need to install ducting made from metal, not flexible plastic tubing as this type can collapse if installed within insulation/insulated walls even though fans are designed for insulated installations. Ducting must run straight from hood opening down through floor below cabinets to curb or drain pipe connection point outside the home that is closest to your kitchen area. Remember that you will require at least 2 to 1 height and length ratio for proper air circulation (one foot ducting run to two feet of height) – this is important as it will affect the performance of the unit. If you have more than 1 foot of height, we recommend adding a muffler to reduce noise.
7. Placing hood vent fan units in an enclosed cabinet is not recommended because fumes may enter cabinetry and circulate back into your kitchen area through heating/cooling system registers, or it can cause moisture buildup even though ventilation systems are designed for recirculating only. Not using ducting with vents at both ends will create dead spots so install a standard duct elbow at each end to avoid this from happening – one outside your home near the curb connection point, and once inside your home on the upper cabinet floor near the hood damper assembly.
8. To reduce noise from the fan unit, a dba sound-rated muffler is recommended for maximum energy efficiency, or you can purchase a “silent” model that runs at 25 percent less power than standard models – however, these brands tend to be more expensive. If ceiling height allows, angled ducting is ideal as it creates better air velocity than conventional straight ducting.
9. Finally, after installation ensure the exterior vent cap of our recirculating rangehood system has proper water drainage so it does not create problems with moisture due to condensation build-up within the hood if installed within an unventilated space such as insulation inside walls. The exterior vent cap should have at least 2″ of clearance above rooftop for proper ventilation so it does not get blocked by snow, falling debris, or leaves. Ensure the exterior hood opening has proper air circulation to activate the fan unit automatically when smoke/steam is detected within your kitchen area – this provides ongoing protection against fumes and odors that may be produced during cooking activities.

How to choose the kitchen hood?

Many homeowners opt for a countertop model which can fit nicely above a cooking surface because it does not require permanent installation.4 However, these models may only be recirculating at most and they can be very expensive due to high power consumption (rated between 1,400 and 1800 c.f.m.)

They also take up valuable countertop space that could otherwise be used for food preparation purposes such as chopping vegetables or washing dishes before/after meals – we recommend installing permanently-mounted ducting within cabinets to eliminate the need for extra kitchen countertop appliances.

Power consumption is important to consider when making your selection because higher-rated units are more expensive – however, it’s not just about recirculating air inside cabinets without exhausting, but also how much heat will be lost into your roof cavity requiring additional heating expense.

Thus, smaller units that consume less power may help reduce energy costs over time, depending upon usage patterns and other conditions such as ceiling height in relation to unit location.

This model uses only 400 watts of power to operate which means you save money by reducing the amount of heat exhausted through ducting – this particular unit runs at 700 cfm vs 1,400 c.f.m. rated units typically found on the market today (1,000 watts) which means it is more energy-efficient.

Installation location can be important to consider when you are trying to find the best unit for your needs – ensure the exterior vent cap of our recirculating rangehood system has proper water drainage so it does not create problems with moisture due to condensation build-up within the hood if installed within an unventilated space such as insulation inside walls.

The exterior vent cap should have at least 2″ of clearance above the rooftop for proper ventilation so it does not get blocked by snow, falling debris, or leaves.

Ensure the exterior hood opening has proper air circulation to activate the fan unit automatically when smoke/steam is detected within your kitchen area – this provides ongoing protection against fumes and odors that may be produced during cooking activities.

It is important to make sure you install your recirculating rangehood unit at the proper height (above cooking surfaces) so it does not become a fire hazard due to overheating or blockage by falling debris – follow installation instructions carefully and verify all electrical works prior to use.

If you did not install a range hood in your home because you were afraid of recirculating contaminated air back into the room, there are new products available on the market which will allow you to enjoy cooking with an open window or exhaust fan running at all times without doing damage to your family’s health by drawing contaminants back inside through your home heating/cooling system – long as the rangehood system is properly installed and maintained.

Although this recirculating range hood system has been designed to protect against any possible fire hazard or another type of damage, both the exterior vent cap and interior mesh chimney are made from lightweight materials which are not suitable for use in high-temperature applications such as an oven environment where excessive heat is present within a confined space – thus we do not recommend installation near any source of heat/flame (e.g., cooker top) … instead you should install the recirculating rangehood unit above your cooktop or under-cabinet cooking surface at least 30cm away for maximum protection while still allowing proper ventilation into.

Standard kitchen hood vent size?

Choosing the right vent hood size is critical. Standard kitchen vent hood sizes need to be correctly matched with the airflow requirements of the cooking equipment that it will handle, and over which it must operate. In some instances, a duct booster fan may be needed in order to meet the total CFM requirement.

The output for standard range hoods is shown in linear feet or inches across your stovetop.

For example, 6-feet 6-inches would be 6′ 6″ long by however many inches wide your stove is. It’s important to get this measurement correct, otherwise, you’ll find yourself either buying another range hood or developing negative pressure in your house when it’s on.

What Is The Standard Of Kitchen Hood Sizes?

Kitchen hood length, width & height

Measure the total linear feet. For example, if you have an 8′ x 5′ stovetop then your range hood dimensions would be 10-feet (length) by however many inches (height) wide your stove is. Keep in mind that most range hoods are 22″ deep so this dimension is not included in the standard size reference chart below.

The depth of the unit is measured from front to back and excludes any recirculating or ducting compartment intrusions (such as wall penetrations).

Standard depth measurements vary among manufacturers with 30+ inches being common for island mount models and 24″ – 36″ range hoods are typically used under cabinets mounted on a wall above a cooktop. This is why it’s so important to take the width of your stovetop when selecting a range hood size.

One last thing about measuring for your new standard-size kitchen hood vent…double check to make sure you’re getting the proper CFM (cubic feet per minute) air flow (listed below). If not, then find one that matches or exceeds this amount.

The higher the CFM capabilities, the easier it’ll be able to remove smoke and odors from cooking activities.

Although if you have an oversized unit on too small of a cooktop, negative pressure will pull smells back down into your house (like an open window does in summertime). It should also be noted that building codes restrict the max CFM for standard range hoods to 400 in most areas, and 600’ish CFM in commercial hoods (where you mostly see 8′ x 5′ cooktops).

Popular Kitchen Hood Sizes:6-feet 6-inches long by however many inches wide your stovetop is.

This would be considered a “standard” size kitchen vent hood. If you have a gas range then you would pick the width of the vent hood to match your stovetop (if it’s 5-feet wide for example, you should choose a 5′ x whatever inches your stovetop is).

If you have an electric cooktop and need to stay within a certain budget then consider getting a standard size hood. It’ll be cheaper but there may be some tradeoffs such as: not having lights, only one level of fan speed, no filters, or maybe even just a basic design.

8-feet long by however many inches wide your stovetop is. It’ll take up more space but if you’re cooking something like a turkey (and need the additional width) then it may be worth considering.

10-feet long by however many inches wide your stovetop is. If you have a large family or entertain frequently then this extra length can make it easier to cook multiple dishes at once or accommodate larger pots/pans. Sometimes venting capacity needs to be increased too (in addition to having an extra 2-3 feet of the duct for exhaust).

For example, if you want to install one standard size hood over two 30″ electric cooktops with 2 ft of each side wall penetration then consider this size range hood. It would have to be a little deeper so the fan motor is high enough above the cooktop to clear the walls.

Vent Hood Width Guide for Standard-Size Kitchen Hoods:4-feet wide by however many inches deep your wall penetrations are.

This is probably best suited if you have just one standard 30″ cooktop or an electric range with no sidewall penetration.

5-feet wide however many inches deep your wall penetrations are.

It should handle most needs and will cover two 30″ cooktops, or a single 36″ range without intrusion into the other stovetop area (if it’s gas). If you’re looking at larger width options then consider this size.

6-feet wide by however many inches deep your wall penetrations are. If you have one standard 30″ cooktop with 2 ft of each side wall penetration then this would be needed to properly ventilate the area.

Conclusion

The standard for kitchen hood sizes is based on the width of your cooktop. If you have a 30-inch wide cooktop, you will need to install an exhaust fan that can move 100 CFM per burner or use one with 135 CFM capacity. Keep in mind that these numbers are just guidelines and every situation may differ slightly depending on how often it’s used and what types of foods are being cooked.
