If you already have a commercial kitchen hood and are shopping for new restaurant equipment, one of the first questions should be:
Will this equipment actually fit properly underneath my existing hood?
The answer involves more than measuring the empty floor space.
You need to consider:
- Hood length
- Hood depth
- Required hood overhang
- Equipment width
- Equipment depth
- Equipment height
- Cooking-surface height
- Fire-suppression coverage
- Gas and electrical connections
- Manufacturer clearances
- Working space for employees
A fryer, range, griddle, charbroiler, wok range, or tandoor may physically fit underneath the stainless steel canopy but still not be appropriate for the existing hood system.
This guide explains how to measure your restaurant hood and cooking equipment, what hood overhang means, why equipment depth matters, and what else to check before purchasing new equipment for an existing cook line.
Start With the Exact Hood Dimensions
Before shopping for equipment, measure the hood itself.
Record:
- Total hood length
- Total hood depth
- Height from the finished floor to the bottom edge of the hood
- Distance from the existing cooking surfaces to the hood
Do not rely only on an old drawing or what someone remembers the hood size being.
Measure the actual installed hood.
Measure the Hood Length
The hood length is the distance from one end of the canopy to the other.
For example, your restaurant might have a:
- 6-foot hood
- 8-foot hood
- 10-foot hood
- 12-foot hood
- 16-foot hood
This gives you a starting point for understanding how much cooking equipment can fit underneath it.
However, the total hood length is not necessarily the same as the usable equipment width.
Why a 10-Foot Hood Does Not Always Hold 10 Feet of Equipment
This is one of the most common mistakes when measuring an existing cook line.
If you have a 10-foot hood, you might assume:
10-foot hood = 10 feet of cooking equipment.
That is not always true.
Canopy-style restaurant hoods generally need to extend beyond the cooking surfaces they cover.
This extra coverage is called:
hood overhang.
What Is Hood Overhang?
Hood overhang is the horizontal distance the hood extends beyond the edge of the cooking equipment.
Cooking smoke and heat do not rise in a perfectly straight vertical line.
As the cooking plume rises, it can spread outward.
The hood therefore needs enough coverage to capture:
- Smoke
- Grease
- Heat
- Steam
- Cooking vapors
before they escape into the kitchen.
How Much Overhang Does a Restaurant Hood Need?
For many traditional canopy-style commercial hoods, model mechanical codes use a minimum horizontal overhang of approximately:
6 inches beyond the cooking surface on open sides.
However, hood designs vary.
Some listed hoods, end-panel configurations, and other specialized systems may have different requirements.
Always confirm the exact hood specifications before deciding how much equipment can fit underneath it.
Example: Equipment Under a 10-Foot Hood
Suppose your hood is:
120 inches long.
You want to install:
- 36-inch commercial range
- 36-inch griddle
- 24-inch fryer
- 24-inch fryer
The total equipment width is:
120 inches.
It looks perfect on paper.
But if the hood needs additional coverage beyond the cooking surfaces at the open ends, filling the entire 120-inch hood with 120 inches of equipment may not leave enough overhang.
This is why you cannot determine fit using total width alone.
Measure Equipment Width
For every appliance you want to place beneath the hood, write down its actual width.
Common restaurant equipment widths include:
- 12 inches
- 18 inches
- 24 inches
- 30 inches
- 36 inches
- 48 inches
- 60 inches
- 72 inches
Use the exact manufacturer's specification sheet.
Do not rely only on the product name.
Nominal Width vs. Actual Width
A product described as a "36-inch range" is generally approximately 36 inches wide, but installation drawings should still be checked.
There may also be components such as:
- Handles
- Gas manifolds
- Side guards
- Control panels
that affect the practical installation area.
Add the Equipment Widths Together
Once you have the exact width of every appliance, add them together.
For example:
- 36-inch range
- 24-inch fryer
- 24-inch fryer
- 36-inch charbroiler
Total:
120 inches.
Then compare that total with the hood's usable capture area rather than just the hood's overall length.
Measure Hood Depth Too
Width is only half the problem.
Restaurant equipment also varies significantly in depth.
A new appliance may fit comfortably from left to right but extend too far toward the front edge of the hood.
Why Equipment Depth Matters
Suppose the previous equipment was approximately 30 inches deep.
You replace it with a new appliance that is significantly deeper.
The front cooking surface may now sit closer to the edge of the hood.
This can reduce the hood's front overhang and affect capture.
Measure the Actual Equipment Depth
Check the manufacturer's specification for:
- Overall depth
- Cooking-surface depth
- Control-panel projection
- Door or handle projection
The cooking surface is particularly important when evaluating hood coverage.
Can Restaurant Equipment Stick Out Past the Hood?
You should not assume that an appliance is properly covered simply because most of it is underneath the hood.
The active cooking surface needs to remain within the hood's intended capture area.
If a deep griddle or range extends substantially beyond the hood, the installation should be reviewed.
Measure the Height of the Hood
Next, measure vertically.
Record the distance from:
Finished floor to the lower edge of the hood.
Then determine the height of the cooking surface on the equipment you want to install.
Why Cooking-Surface Height Matters
Not every commercial cooking appliance sits at the same height.
Compare:
- Commercial range
- Stock pot range
- Countertop griddle
- Tandoor
- Countertop charbroiler on a stand
The cooking surfaces can be at very different heights.
This means measuring only from the floor to the hood does not tell you everything.
Measure From the Cooking Surface to the Hood
The important vertical relationship is between the cooking surface and the hood.
For many canopy-style commercial hood arrangements, model mechanical codes limit the distance between the front lower edge of the hood and the cooking surface to:
No more than 4 feet.
However, the hood's manufacturer may specify a smaller approved mounting range.
Some commercial canopy hoods, for example, are listed for mounting within a particular range such as approximately 33 to 48 inches above the cooking surface.
The exact hood nameplate and installation instructions should be followed.
Why a Taller Appliance Can Create a Problem
Suppose your hood worked correctly with a relatively low stock pot range.
You replace it with a much taller countertop appliance mounted on an equipment stand.
The cooking surface may now be significantly closer to the hood.
Even though the appliance fits underneath it physically, the final installation may no longer match the hood's intended configuration.
Why a Shorter Appliance Can Matter Too
The opposite can happen.
If a new cooking surface is much lower than the old one, the distance to the hood increases.
If that distance exceeds the hood's approved mounting range, capture performance may be affected.
Check Whether the Equipment Uses Legs or Casters
Restaurant equipment often comes with:
- Adjustable legs
- Casters
These bases can have different heights.
Changing from legs to casters may raise or lower the equipment enough to change the hood-to-cooking-surface relationship.
Use the Final Installed Height
When comparing a new appliance with the hood, use the height it will have after installation.
That means including:
- Legs
- Casters
- Equipment stand
- Chef base
if applicable.
Countertop Equipment Needs Special Attention
A countertop griddle or charbroiler may appear small on its own.
But it needs to sit on something.
That could be:
- Equipment stand
- Chef base
- Stainless steel work surface
The combined height of the equipment and base is what matters.
Example: Countertop Griddle on a Stand
Suppose a countertop griddle is 15 inches high.
It sits on a 24-inch equipment stand.
The resulting cooking surface may be around the same general height as a conventional floor-model appliance.
If you later place that same griddle on a much taller stand, the hood clearance changes.
Check the Hood Type
Not every restaurant hood is the same.
You may have:
- Wall canopy hood
- Island canopy hood
- Low-proximity hood
- Backshelf hood
- Type I hood
- Type II hood
Different hood styles can have different equipment-positioning requirements.
Wall Canopy Hood
A wall canopy hood is mounted along a wall and projects over the cook line.
This is one of the most common arrangements in commercial restaurant kitchens.
Typical equipment may include:
- Range
- Fryer
- Griddle
- Charbroiler
- Wok range
Island Hood
An island hood is positioned over cooking equipment away from a wall.
Because the cooking plume can move in more directions, the capture area may need to be planned differently.
Low-Proximity Hood
A low-proximity or backshelf-style hood sits closer to the equipment than a traditional overhead canopy.
You cannot use the same measuring assumptions for a low-proximity hood that you would use for a standard canopy hood.
Check Whether You Have a Type I or Type II Hood
Hood type matters just as much as physical size.
Type I Hood
Designed for grease-producing cooking applications such as:
- Frying
- Griddling
- Charbroiling
- Other grease-producing cooking
Type II Hood
Designed primarily for:
- Heat
- Steam
- Moisture
- Condensation
without grease-laden cooking exhaust.
A Fryer May Physically Fit Under a Type II Hood, but That Does Not Make It Appropriate
This is a good example of why "fit" means more than dimensions.
You could have:
- Enough width
- Enough depth
- Enough height
and still have the wrong hood type for the cooking process.
Check the Hood Nameplate
If you have an existing hood, look for its manufacturer information.
The nameplate may identify:
- Manufacturer
- Model
- Listing information
- Approved mounting conditions
This information can be extremely useful when evaluating new equipment.
Find the Original Hood Drawings if Possible
If you have access to the restaurant's original plans, hood drawings, or submittals, keep them.
They may show:
- Original cooking equipment lineup
- Hood dimensions
- Exhaust airflow
- Make-up air
- Duct connections
- Equipment placement
This can help professionals understand what the system was originally designed to serve.
Check Fire-Suppression Coverage
This is one of the most important things people forget.
A Type I commercial hood usually works together with a fire-suppression system for the cooking equipment underneath it.
If you change the cook line, the existing fire-protection arrangement may need to be reviewed.
Why Equipment Position Matters for Fire Suppression
Imagine your existing cook line is:
Range | Fryer | Griddle
You replace it with:
Fryer | Fryer | Charbroiler
The total width might be similar.
But the type and position of the cooking hazards have changed.
This is why equipment should not be rearranged based only on whether it fits underneath the stainless steel hood.
Can You Move Equipment Side to Side Under the Hood?
Possibly, but moving the equipment can affect:
- Hood overhang
- Fire-suppression coverage
- Gas connections
- Electrical connections
- Employee workflow
Significant cook-line changes should be reviewed before installation.
Check Gas Connections
If the new appliance uses natural gas or propane, check more than the available floor space.
You also need to know:
- Gas type
- BTU input
- Gas inlet size
- Available gas capacity
- Location of the connection
Why BTU Matters When Adding Equipment
A larger or more powerful appliance may demand considerably more gas than the equipment it replaces.
For example, the gas demand of:
- High-output wok range
- Multiple fryers
- Large commercial range
can add up quickly.
Available hood space does not guarantee adequate gas capacity.
Check Gas Connector Location
Movable gas equipment may use:
- Flexible commercial gas connector
- Quick-disconnect fitting
- Restraining device
The new appliance position should allow these components to be installed appropriately.
Check Electrical Requirements
Electric restaurant equipment may require different electrical supplies.
Before ordering, check:
- 120V
- 208V
- 240V
- Amperage
- Single phase or three phase
- NEMA plug type
- Hardwired or plug-in connection
A nearby outlet does not automatically mean it can power the new equipment.
Check Manufacturer Clearances
Cooking equipment may have required clearances from:
- Combustible surfaces
- Walls
- Nearby equipment
- Other building materials
Use the installation instructions for the exact model.
Can Equipment Be Packed Side by Side?
Commercial restaurant equipment is often installed tightly together.
However, that does not mean every appliance can automatically touch the appliance next to it.
The manufacturer may specify installation clearances that need to be maintained.
Check Equipment Doors
Do not forget moving parts.
A piece of equipment may fit when everything is closed but become difficult to use once employees begin opening:
- Oven doors
- Cabinet doors
- Fryer doors
- Access panels
Check Handles and Controls
Handles can extend beyond the equipment body.
Control knobs and panels can also need space around them.
When planning the cook line, imagine the equipment being actively used rather than simply sitting unused.
Check Service Access
Restaurant equipment eventually requires maintenance.
Technicians may need access to:
- Rear panels
- Side panels
- Gas valves
- Electrical components
- Burners
A cook line that is packed too tightly can make service more difficult.
Check Cleaning Access
Commercial kitchens need to be cleaned underneath and behind equipment.
Equipment on casters can make this easier.
If you are adding another appliance, think about whether employees will still be able to clean the area effectively.
Check Employee Working Space
Another piece of equipment can fit technically but still make the kitchen uncomfortable or unsafe to work in.
Ask:
- Can cooks stand in front of the equipment?
- Can they remove fryer baskets?
- Can oven doors open?
- Can large stock pots be lifted?
- Can other employees walk behind the cook?
Check the Aisle in Front of the Cook Line
A deeper appliance extends farther into the kitchen.
This can reduce aisle width even if it fits underneath the hood.
Always consider how the new equipment changes the usable floor space in front of the cook line.
Check Landing Space
Cooking equipment usually needs nearby space for:
- Pans
- Plates
- Food containers
- Tools
- Finished dishes
Filling every available inch with equipment can eliminate useful landing and prep space.
More Equipment Is Not Always a Better Kitchen
It can be tempting to fill every inch underneath a large hood.
But a good restaurant cook line needs more than maximum cooking capacity.
It also needs:
- Workflow
- Employee access
- Cleaning access
- Serviceability
- Prep space
How to Check if a Fryer Will Fit Under Your Hood
Before purchasing a Commercial Fryer, check:
- Fryer width
- Fryer depth
- Cooking-surface position
- Available hood overhang
- Fire-suppression coverage
- Gas or electrical requirements
- Clearance from neighboring equipment
How to Check if a Commercial Range Will Fit
Before purchasing a Commercial Range, compare:
- Total width
- Depth
- Overall height
- Backguard height
- Cooking-surface height
- Gas input
- Hood coverage
Also confirm that the oven doors have enough room to open into the aisle.
How to Check if a Griddle Will Fit
For a commercial griddle, determine whether it is:
- Countertop
- Floor model
A countertop model also requires a suitable base, which changes its final working height.
How to Check if a Charbroiler Will Fit
Charbroilers deserve particular attention because they can produce substantial heat, smoke, and grease.
Check:
- Width
- Depth
- Cooking-surface height
- Hood type
- Hood coverage
- Fire-suppression coverage
How to Check if a Stock Pot Range Will Fit
A Commercial Stock Pot Range may be relatively low compared with other equipment.
But you also need to consider the large pot placed on top of it.
Measure the working space needed for:
- Stock pot
- Pot lid
- Stirring
- Adding ingredients
How to Check if a Wok Range Will Fit
When considering a Commercial Wok Range, check:
- Overall dimensions
- Burner position
- Gas requirements
- Cooking duty
- Hood capture area
High-temperature wok cooking can create significant heat and cooking emissions.
How to Check if a Tandoor Will Fit
A Commercial Tandoor requires some additional measurements because of its vertical cooking method.
Check:
- Tandoor width
- Tandoor depth
- Overall height
- Height of the top opening
- Hood height
- Working space above the opening
Why Tandoor Working Space Matters
A cook needs to insert and remove:
- Long skewers
- Naan tools
- Bread pads
through the top opening.
A tandoor can fit physically beneath a hood but still have inadequate working space if the hood sits too close above the opening.
Do Not Forget Tandoor Skewer Height
When measuring for a tandoor, think beyond the appliance itself.
Imagine the cook holding a long skewer vertically and inserting it into the oven.
The employee needs practical overhead working room.
How to Measure an Existing Hood Step by Step
- Measure the hood from left to right.
- Measure the hood from back to front.
- Measure from the floor to the lower edge of the hood.
- Measure the existing cooking-surface height.
- Record the equipment currently underneath the hood.
- Locate the hood manufacturer and model information if available.
- Photograph the existing equipment arrangement.
- Record where the gas and electrical connections are located.
Then Measure the New Equipment
For the new appliance, record:
- Width
- Depth
- Overall height
- Cooking-surface height
- Gas or electrical requirements
- Required installation clearances
Use the manufacturer's specification sheet rather than estimated dimensions.
Make a Simple Cook-Line Drawing
You do not need complicated design software to do an initial check.
Draw the hood as a long rectangle.
Underneath it, draw each proposed appliance using its actual width.
Label each piece:
- 36" range
- 24" fryer
- 36" griddle
This makes it much easier to see how the equipment fits together.
Do a Top-Down Drawing Too
A front view shows equipment width.
A top-down view helps you understand:
- Equipment depth
- Front hood overhang
- Aisle space
This can reveal problems that are not obvious from a front view.
Example Cook Line
Imagine an existing hood where you want:
- 36-inch range
- 24-inch fryer
- 24-inch fryer
- 36-inch griddle
Total appliance width:
120 inches.
Before deciding that a 10-foot hood is enough, also check:
- Required end overhang
- Front overhang
- Equipment depth
- Hood mounting height
- Fire suppression
- Utilities
What if the Equipment Is Too Wide?
Possible solutions may include:
- Choosing a narrower appliance
- Using fewer appliances
- Replacing multiple smaller appliances with one larger unit
- Reworking the cook line
- Evaluating whether the hood can be modified
- Adding another approved cooking area
What if the Equipment Is Too Deep?
You may need to consider:
- A shallower model
- A different equipment layout
- A different hood configuration
Do not simply push equipment farther underneath the hood if that creates utility or clearance problems behind it.
What if the Equipment Is Too Tall?
If the final cooking surface sits too close to the hood, options depend on the equipment and hood.
Do not simply remove approved legs or modify the appliance to make it shorter.
Use equipment and mounting configurations approved by the manufacturer.
What if the Equipment Is Too Short?
If the cooking surface sits too far below the hood, the hood may not operate within its listed mounting range.
A suitable equipment stand may sometimes be part of a properly designed solution for countertop equipment.
Again, verify the exact installation.
What if the Hood Is Too Small?
If the existing hood does not provide enough coverage for the equipment your menu requires, possible options may include:
- Changing equipment sizes
- Changing the cook-line arrangement
- Modifying or replacing the hood where appropriate
- Creating a second cooking station
- Using appropriately listed alternative equipment where suitable
Should You Buy the Equipment Before Measuring the Hood?
No.
Measure first.
This is especially important for large or expensive equipment such as:
- Ranges
- Fryers
- Charbroilers
- Wok ranges
- Tandoors
Finding out that a new appliance does not fit properly after delivery can become an expensive problem.
What if You Are Taking Over an Existing Restaurant?
Do not assume the previous restaurant's cook line will work for your concept.
The previous operation may have used:
- One fryer
- Small griddle
- Range
while your concept may require:
- Two fryers
- Charbroiler
- Tandoor
- Stock pot range
The hood and utilities should be reviewed around your actual equipment package.
Planning an Indian Restaurant Under an Existing Hood
An Indian restaurant may use:
These appliances can have very different:
- Widths
- Depths
- Heights
- Gas loads
- Cooking methods
The entire cook line should be considered together.
Should You Leave Room for Future Equipment?
If you are designing a new kitchen, it can be useful to consider future menu growth.
You may eventually want to add:
- Another fryer
- Another tandoor
- Griddle
- Charbroiler
Planning ahead can be easier than trying to squeeze another appliance into a completely full cook line later.
But Do Not Oversize Everything Just for Future Growth
Larger hoods and larger equipment packages can increase:
- Construction cost
- Energy use
- Kitchen space requirements
The goal is to plan intelligently rather than simply making everything as large as possible.

Frequently Asked Questions
How do I know if restaurant equipment will fit under my hood?
Compare the hood's length, depth, mounting height, and required overhang with the equipment's width, depth, overall height, and cooking-surface height. Also confirm fire-suppression coverage and utility requirements.
Can I fill the entire width of my restaurant hood with equipment?
Not necessarily. Canopy hoods generally require additional coverage beyond cooking surfaces, so the usable equipment width may be less than the hood's total width.
How much should a hood extend past restaurant equipment?
Many canopy-style hood arrangements use at least 6 inches of horizontal overhang beyond cooking surfaces on open sides, although the exact hood listing and installation requirements should be checked.
How high should a commercial hood be above cooking equipment?
The correct mounting range depends on the specific hood. Model mechanical codes commonly limit the vertical distance between the front lower edge of a canopy hood and cooking surface to no more than 4 feet, while individual listed hoods may specify a narrower range.
Can equipment stick out past the front of a hood?
The cooking surface should remain within the hood's required capture area. A deeper appliance can reduce the front overhang and should be checked before installation.
Does equipment depth matter under a hood?
Yes. A deep appliance may extend too far toward the front edge of the canopy even if its width fits perfectly.
Does equipment height matter?
Yes. The height of the cooking surface determines its vertical relationship to the hood.
Do casters change whether equipment fits under a hood?
They can. Casters and legs can have different heights, which changes the final cooking-surface height.
Can I put a countertop griddle under my hood?
Potentially. Include the height and dimensions of the equipment stand or chef base when evaluating the final installation.
Can I add another fryer if there is empty space?
Possibly, but empty floor space does not automatically mean the hood, fire suppression, gas system, or electrical system can support another fryer.
Can I add a tandoor under an existing hood?
Possibly. Check width, depth, overall height, hood coverage, gas requirements, and overhead working space for skewers and naan tools.
Can I move equipment around under my hood?
Possibly, but changing appliance positions can affect hood coverage, fire-suppression coverage, and utility connections.
Does the hood type matter?
Yes. A Type II hood is not automatically appropriate for grease-producing equipment just because that equipment physically fits underneath it.
Do I need to check fire suppression when changing equipment?
Yes. Major equipment changes or repositioning can affect the existing fire-protection arrangement.
Does gas capacity matter if the appliance fits?
Yes. A new gas appliance may add substantial BTU demand even if it fits physically.
Does electrical voltage matter?
Yes. Check voltage, amperage, phase, plug type, and circuit availability for electrical appliances.
Should I use the equipment spec sheet when measuring?
Yes. The exact specification sheet is the best source for the appliance's dimensions and utility requirements.
Should I measure before buying equipment?
Yes. Measuring the hood, cook line, delivery path, and utilities before ordering can prevent expensive installation problems.
Final Thoughts: Will Your Restaurant Equipment Fit Under the Hood?
Determining whether restaurant equipment fits beneath an existing hood requires more than checking the available floor space.
Start by measuring:
- Hood length
- Hood depth
- Hood height
Then compare those measurements with the appliance's:
- Width
- Depth
- Overall height
- Cooking-surface height
After the physical measurements work, check:
- Hood overhang
- Hood type
- Fire-suppression coverage
- Gas capacity
- Electrical capacity
- Equipment clearances
- Employee workflow
Remember that a piece of equipment can physically fit underneath the hood and still not be appropriate for the existing system.
Nishi Enterprise carries Commercial Cooking Equipment, including Commercial Fryers, Commercial Ranges, Stock Pot Ranges, Wok Ranges, and Commercial Tandoors.
If you are planning a complete restaurant or trying to determine how equipment will fit into an existing kitchen, you can also learn more about Nishi Enterprise's Restaurant Design Consultation.
The simplest rule is this: measure the hood, measure the exact equipment, check the required overhang and vertical relationship, and then make sure the fire suppression and utilities still work with the new cook line.
