Are you redesigning your kitchen or designing a kitchen from scratch? If so, then it’s important to ensure that you include a vent hood in your plans. A kitchen vent hood is a key requirement for any kitchen space.

A vent hood will ensure that your kitchen has the right level of ventilation. This means that when you are cooking or using your kitchen appliances, the room won’t fill up with grease fumes, smoke, or even condensation. Instead, a high-quality vent hood will keep your kitchen air clean and clear, regardless of how often you use it for cooking.

However, for a range hood to provide the right benefits, it needs to be the ideal size. That’s why it’s important to explore range hood dimensions before you purchase an appliance like this for your home.

Below, we’ll discuss everything that you need to know about kitchen vent hood dimensions including why they are important.

What Are The Standard Range Hood Sizes?

The standard range hood sizes are usually 24’’, 30’’, or 30’’ for the width. However, it can depend on the style of the hood. Hoods available from our store are available in widths up to 100’’. This is why it can be important to explore a kitchen hood size chart before you decide on a purchase.

There is no standard height for a range hood as it largely depends on the layout and design of your kitchen as well as the height of your ceiling.

How Far Can You Vent A Range Hood?


If you are selecting a ducted range hood for your kitchen, then you need to think about the overall distance that you can choose for the vent. Generally speaking, a vent hood can be as much as 35’’. This will be the case if it is a straight run. If it includes elbows, then you need to consider a smaller vent length. Your range hood will always provide instructions that will allow you to calculate the distance that you need. Do be aware that a vent that is too long will cause practical issues and mean that the appliance does not function correctly. If the duct is far too long, then the air is not going to reach the outside of your home. Instead, it will be cycled back into your kitchen. Your first sign of this will be the smell lingering in your kitchen after you have finished cooking.

How To Determine The Right Dimensions For Your Range Hood

To ensure that you get the right range hood, you will need to take down a few dimensions for your kitchen space. This includes taking measurements of the cooking surface that is part of your kitchen, the area between the various cabinets and the height as well as the depths of the cooking surface.

There are certain steps that you can take that will ensure you get all the dimensions that you need before committing to a purchase.

Measure Your Cooking Surface Width

First, you need to measure the width of your cooking surface. You should do this by using a measuring tape and starting from one side before running the tape across the opposite side. Do note that unlike measuring something like a TV, you should not measure diagonally across the cooktop. Instead, the table needs to be parallel to the edge of the cooktop. This will ensure that you gain the precise measurement that you need.

Measure Between The Cabinets

The range hood will fit between the cabinet space. To measure this area, you need to secure the tape on one side of the cavity and then extend the tap all the way across the opposite side. Again, for the most accurate measurement, you need to make sure that the tape is completely parallel with the surface of your cooktop.

Measure Space And Height Above The Cooking Surface

It’s important to take the measurement of the height above the cooking surface. To do this, you will need to secure the tape at the base of the ceiling or the cabinets, depending on where your range hood is going to be positioned.When you take this height, keep in mind that your range hood should be anywhere between 24’’ to 36’’ away from the surface of the cooktop. As such, you should take this length off the total height that you measure. It is important to ensure that your range hood at least meets the minimum height requirement away from your cooktop surface.

What Is The Minimum Height Requirement?

Each range hood will have a different minimum and maximum height for installation purposes. The majority of range hoods will suggest a minimum of 24”. This is the standard if you have an electric cooktop. If you have a gas cooktop, then you may find that the minimum is 27 inches.

It’s possible that you currently have a completely empty space that needs a total redesign. If that’s the case, then you will still need the dimensions of your finished kitchen before completing the purchase of a range hood. You can use our 3-D configurator to determine the layout of your kitchen space before you settle on the right choice for your home.

How Does The Type Of Range Hood Impact Dimensions?

There are various types of range hoods that you can consider for your kitchen space. The options include:

  • Wall mount
  • Ceiling mount
  • Under Cabinet

Wall Mount


Wall-mounted range hoods are installed against the wall, between the cabinets and over the cooktop. They must be fitted directly over the cooktop to provide the right benefits. These systems do not need to have anything mounted above them. The typical width will usually be anywhere between 30’’ to 40’’. However, this does depend on the model that you choose. Custom range hoods are available that are significantly wider. There are also commercial-style range hoods that are also far larger than the typical range mentioned. These models tend to have more advanced features which can be ideal if you want to ensure that you have a professional set-up in your kitchen space.

Ceiling Mount

A ceiling mount provides a unique design option for your kitchen. It ensures that you can fit the range hood anywhere in your kitchen space. This is mostly used for kitchen islands where the cooktop takes a central position in the room. The range hood is a crucial part of the room design and will often be a focal point of your home. A ceiling mount should always be positioned directly over the cooktop and should be at least as large as the full size of the cooktop.

Typically, they will be between 30’’ to 60’’ wide. However, this again does depend on the style of your kitchen. If you have a larger cooktop in the center of your kitchen then you will need a larger, wider range hood to match. At CopperSmith, we have a wide range of ceiling-mounted range hoods for you to choose from. These can be the perfect addition to a kitchen island that you already have installed or one that you are thinking about adding to your home in the future. You just need to find the right style to match your kitchen decor.

Under Cabinet

It’s possible that you don’t want to disrupt the design elements that you already have in place for your kitchen. This could be the case whether you have a concept design for your kitchen or an existing kitchen model in your home. If that’s the case, a cabinet range hood could be the ideal solution. A cabinet range hood will fit neatly underneath your cabinets while still providing the full practical benefits that you need for your space.

It is important to understand that these range hoods are far smaller than the options that were previously mentioned. Usually, you can explore an under cabinet range hood that is between 20’’ and 60’’.

In some cases, under cabinet range hoods are less powerful than wall-mounted or ceiling-mounted options. As such, you may want to consider ensuring that there is a shorter length between the range hood and the top of the oven top. This will ensure that a less powerful range hood will still provide the practical benefits that you need for your kitchen space without any issues. Our under-cabinet range hoods are powerful, efficient and designed to provide a valuable addition for any kitchen space.

Why Are Range Hood Dimensions Important?

Range hood dimensions are important for key practical reasons. If your range hood is not the right size, then it will not provide the benefits that you need in your kitchen space. This means that you could notice issues with:

  • Lingering smells
  • Smoke filling your kitchen
  • A buildup of grease

In contrast, if you get the right dimensions for your range hood, then you’ll find that it does ensure that your kitchen air quality remains at the right level. It will also keep your kitchen space a pleasant place, whether you’re cooking a meal or sharing dinner with the family.

The dimensions of your range hood will impact everything from whether it covers the full surface of your oven top to if it’s the right height away from your oven.

Safety Concerns

If the height and width aren’t right on your range hood, it could even cause a safety issue. If your range hood is not effective at removing the fumes from the kitchen, then it could lead to a buildup of grease fumes that would spread through the kitchen and impact countless surfaces around your home.

Aesthetic Issues


From a design perspective, it’s worth noting that your range hood won’t look right if you don’t get the dimensions correct when you are ordering this product. Your range hood will always catch the attention of anyone entering your kitchen. The edge of the range hood is at the perfect eye level. Therefore, it needs to look right and fit perfectly with the other parts of your kitchen design. If you get the dimensions right, then it will blend in seamlessly and look like the perfect addition to this space.

At CopperSmith, it’s easy to ensure that you get the perfect size of range hood for your kitchen. As well as other customization options, you can order a range hood based on a specific height and width that will work best for your kitchen setup.

Is Your Current Range Hood Too Small?

You might be wondering whether your range hood is the right size. There are several signs that you should watch out for which will tell you that you need to consider upgrading your range hood.

Your Range Hood Doesn’t Look Right

From an aesthetic point of view, your range hood should look like it fits with the rest of your kitchen. If it doesn’t then there’s a chance that your range hood is too small. This could be a mistake by the original contractor or it may have been made during a renovation by the previous homeowner. It’s important that your range hood does compliment your overall kitchen design.

You Range Good Isn’t Clearing The Fumes

Another sign that you need a larger range hood will be if it is not clearing the fumes around your kitchen. If your range hood is not large enough for your cooktop, then it is never going to be able to clear all the fumes that are created when you are cooking. Particularly if you love to experiment in the kitchen.Of course, problems here can also be a sign that you are not maintaining your range hood correctly. You should aim to clean and inspect your range hood every couple of months to ensure that it is delivering the right benefits.

Unpleasant Odors

Range hoods don’t just remove fumes from your kitchen. They are also useful for getting rid of any odors that are left over after cooking. If you have your range hood switched it is working correctly, then you shouldn’t be able to smell anything an hour or so after you have finished cooking. If the odors remain, then this could be another sign that your range hood is too small for your kitchen space.

If you are worried that your range hood is too small, then you should consider an upgrade. When upgrading your range hood, it’s important to invest in a high quality appliance. If a range hood isn’t manufactured to the right standards, then it’s going to cause issues, regardless of how large it is. That’s why we are delighted to offer a fantastic selection of range hoods that could be a suitable addition for any kitchen or home. Purchasing a range hood from CopperSmith ensures that your appliance will last for years and keep your kitchen fume free.

Is Your Range Hood Too Large?

It’s also possible that your range hood is too large for your kitchen. Be aware that a range hood will be too powerful for your kitchen if it removes air far faster than it can be replaced. This can be an issue in smaller kitchens but is quite rare. Here are some of the signs that this might be the case.

More Aesthetic Issues

As with a small range hood, you may find that a range hood that is too large doesn’t fit well with the rest of your kitchen. It could seem obtrusive and may overshadow all the other design elements. A range hood doesn’t need to be any larger than your oven top. If you have a small cooking surface, then you’ll have a small range hood. On average, a range hood should never be more than six inches larger than the overall cooktop.

Heavy Costs

You could also find that a larger range hood is far less efficient. It could cost a fortune to run without providing any more real practical benefits than a small model. A range hood will also become more expensive if it is not maintained correctly. For instance, on inspection, you may find that your range hood is clogged up with dirt and grease. If that’s the case, then you will need to clean it to ensure that you continue to gain the right standards of efficiency. If your range hood is inefficient, then it could be worth upgrading to a modern small, even if you don’t need to change the size.

Too Loud

A larger range hood could also be quite loud and be a disruptive presence in your kitchen. There’s no need for a range hood to be deafening. This can be another sign that you are not maintaining it correctly. Or, it could suggest that you need to consider switching to a smaller model. Depending on the size of your oven top, a smaller model could be quieter and still serve its purpose. You just need to make sure that it is large enough to cover the width of the cooktop including all the burners.

Ductless Range Hood Dimensions

You may have decided on a ductless range hood for your kitchen. Ductless range hoods provide a lot of benefits. They are easier to install and can be more cost friendly. They don’t require a vent to the outside of your home and insteal will recirculate the air around the property. However, it’s still important to make sure that you do choose the right size for your ductless range hood.

As with a standard range hood, ductless kitchen vent hood dimensions are important. Despite the differences in design, you still need to make sure that your range hood covers the full surface of the cooktop including all of the different burners.Is The Height of A Ductless Range Hood Different?

Ductless range hoods are available in a variety of heights and widths. You may assume that a ductless range hood needs to be closer or farther away from the cooktop compared to a standard appliance. However, this is not the case. Instead, you should still fit your ductless range hood anywhere between 24’’ and 30’’ away from the top of your cooking surface. This will ensure that it does provide the right benefits when cooking in your kitchen and that you don’t have to worry about safety issues.

Other Points To Consider

There are a few other points to consider when you are thinking about the size of your range hood. This will help ensure that you make the right choice and guarantee that it is easier to fit your range hood in your kitchen.

What Is Included In The Measurements?


First, it’s important to check what is included in the measurements of your range hood. If you purchase a range hood from CopperSmith straps and rivets will not be included in the width provided. These will protrude as much as ⅝ away from your range hood beyond the standard width. This is something to consider if you want to ensure that your range hood is going to fit in your cabinet space neatly without any gaps.

In contrast, the crown height of the range hood will be included in the overall height of the hood. As such, you do not need to subtract this to ensure that you do gain an accurate measurement.

Installation

The size of the range hood may make it more or less difficult to install as a DIY project. It is possible to install a range hood yourself. However, generally, you will need at least two people to hold the range hood and ensure that it is fitted at precisely the right point on the ceiling or countertop. This is one of the reasons why it is recommended that you do consider investing in the support of a professional team to fit the range hood for you.

Venting Strength

You also need to consider the venting strength of your range hood. Venting strength is measured in cubic feet per minute (CFM). A higher number will mean that a venting hood has a higher capacity to replace the air in the kitchen at a far greater frequency. Ideally, you should aim for a CFM of 200 to 300 CFM. This will be suitable if you are using your standard, residential kitchen everyday to cook food. If you are purchasing a range hood for a commercial property, then you will need to invest in an appliance with a higher CFM. At CopperSmith, all of our custom range hoods are designed to provide a high level of power in any type of kitchen. They will always deliver the superior performance that you need.

Do You Have A Grill?

It’s possible that you have a grill as part of your oven top. If you have a grill, then you may already know that they produce more heat and smoke compared to your standard design. For this reason, it’s worth ensuring that you are investing in a larger range hood to account for this. That way, you can ensure that your kitchen remains clear, regardless of what food you are preparing on your grill.

Do Kitchen Hood Dimensions Impact Cost?

The size of your range hood will impact the cost of this appliance. If you need a large range hood, you should expect to pay a larger cost compared to one of the smaller designs. You can find out exactly how much the size of range hood you need will cost by accessing a custom quote on our website.Do note that the size of your range hood isn’t the only factor that will impact the cost of your purchase. The total price will be affected by:

  • Any custom features
  • The material you choose
  • Interior features
  • And More

Choose The Right Range Hood For Your Kitchen

There are various points to consider when choosing the right size of range hood for your kitchen. It is important to ensure that it covers the area of your cooktop and that it is the right distance away from your cooking surface. It’s easy to select the perfect size when you order a range top from CopperSmith. You can customize every aspect of the design to ensure that you get the right fit.

Of course, size isn’t the only point that you should consider when you are choosing a range hood for your kitchen space. There are other points to think about as well. For instance, you might want to explore additional elements such as a pot rail finish. This will provide you with a convenient place to hang your pots and pans, keeping your kitchen clutter free. You can also alter different specific aspects of the range hood design including the rivet style or the crown profile.

Arguably, one of the most important considerations is the material of your range hood. At CopperSmith, we believe copper range hoods provide fantastic benefits to buyers. They will:

  • Last for years
  • Provide antibacterial properties
  • Add a stunning, unique design element to your kitchen
