What Is Range Hood Clearance?
Range hood clearance is the vertical distance from the cooking surface to the hood’s lowest point. The correct height depends on the range and hood instructions, plus locally adopted code. Electric and gas ranges often use different planning ranges, but those numbers are not universal rules. Check both manuals, resolve any conflict before installation, and verify the finished measurement.
What range hood clearance means
Range hood clearance is the space between the cooking appliance’s cooking surface and the hood’s lowest point. It affects whether the installation follows the equipment instructions and can influence how well the hood captures smoke and grease. The right distance is specific to the range, hood, and applicable local requirements.
You may see a general recommendation online, such as 24 inches or 30 inches. Treat these figures as starting points for research, not as a substitute for the manuals or code. Many residential plans fall around 24–30 inches for electric ranges and 30–36 inches for gas ranges, but actual permitted heights vary.
I have seen spec sheets cause confusion because one lists a minimum while another gives a range of allowed mounting heights. Both details matter. The range manufacturer’s required clearance and the hood manufacturer’s mounting instructions must be considered together. If they appear to conflict, do not choose the smaller number or average the two. Ask the manufacturers or your local building official, also known as the authority having jurisdiction (AHJ), for direction.
Key takeaway: Use general ranges only to plan. The manuals and locally adopted code determine what is allowed for your installation.
How to measure range hood clearance and inspect the installation surface
Measure straight up from the range’s cooking surface to the hood’s lowest point. Do not measure from the floor, countertop, or top of the backsplash. This shared reference point lets you compare the actual installation with both manuals’ clearance requirements.
Find the correct measuring points
The cooking surface is the surface where pots and pans sit, not the floor or the counter beside the range. For a hood, measure to its lowest point above the cooking area. That may be the bottom edge, a low part of an angled design, or another component identified by the hood instructions.
Before marking a height:
- Identify the exact range and hood models.
- Find each model’s installation manual and listing information.
- Note the range fuel type and the hood’s mounting configuration.
- Check the stated minimum and maximum clearance, if both are given.
- Confirm which code edition and local amendments apply.
A tape measure and level can help you mark the proposed hood-bottom line. If the range is already in place, measure from its cooking surface. If it is not, use the appliance manual to establish the planned cooking-surface height, then recheck the measurement after installation.
Check the surface and mounting support
Inspect the wall and any cabinets above or beside the range. Their materials and location matter because cabinets and other combustible construction must meet the range and hood listing instructions and adopted code. A tile, stone, or metal backsplash does not, by itself, allow a lower hood or reduced overhead clearance.
Also confirm that the wall or cabinet can support the hood as its instructions require. A correct height is not enough if the hood is not securely mounted.
Next step: Record the measured clearance and compare it with each appliance’s stated limits before drilling or fastening.
Setting hood height: manufacturer specifications and installation precision
The permitted hood height is the overlap between the range’s requirements and the hood’s instructions, interpreted under local code. Check both sets of directions before setting the mounting line. Do not assume a common internet measurement applies to your equipment, even when the range and hood seem typical.
Use the manuals to identify the full allowed range, not just one number. A minimum is the smallest permitted distance; a maximum, when stated, is the greatest permitted distance. The hood may also list a mounting range tied to its design or installation method. Stay within the stated limits and follow any model-specific notes.
| Planning detail | What to check | Why it matters |
|---|---|---|
| Electric range | Range and hood instructions; many plans fall around 24–30 in. | The actual minimum depends on the listed equipment and code. |
| Gas range | Range and hood instructions; many plans fall around 30–36 in. | Do not treat the planning range as a universal code rule. |
| Conflicting instructions | Contact the manufacturers or AHJ | Do not average the heights or assume the smaller clearance is acceptable. |
| Combustible cabinet | Check location and required clearance | A backsplash does not replace overhead clearance rules. |
For example, suppose a particular range manual requires at least 30 inches, while the hood manual permits installation only from 24 to 28 inches above the cooking surface. These hypothetical instructions do not provide a valid shared height. Stop and request direction from the manufacturers or AHJ; do not install at 28 inches just because the hood permits it.
Height also affects performance. A hood mounted too high may capture smoke and grease poorly. One mounted too low may violate its listing and expose the hood or nearby cabinetry to excess heat. The acceptable installation must meet the equipment requirements, not just look balanced above the range.
Key takeaway: Mark the final hood-bottom height only after you have confirmed that the range and hood instructions agree.
Range hood clearance installation case studies
These planning examples show how to apply the measurement method. They are not reports of specific installations or approval for any model. In each case, use the actual appliance instructions and local code before work begins.
Case 1: Electric range with matching instructions
Assume the range and hood manuals both allow a 30-inch clearance, and no local rule changes that requirement. Measure 30 inches vertically from the cooking surface to the hood’s lowest point, then confirm the height again after mounting.
If the range surface is 36 inches above the floor in this example, the hood bottom would be 66 inches above the floor. That floor measurement is only a layout aid; the required clearance remains 30 inches from the cooking surface.
Case 2: Gas range with conflicting instructions
Assume a gas range’s manual requires a 32-inch minimum, while the hood’s permitted mounting range ends at 30 inches. There is no shared height in those hypothetical instructions. Do not pick 30 or split the difference. Pause and obtain guidance from the manufacturers or AHJ.
Case 3: New backsplash changes the wall finish
Suppose tile is added behind a range, but the hood height remains unchanged. The tile does not automatically reduce the required overhead clearance. Recheck the range and hood manuals and confirm the cabinet and other combustible surfaces meet the applicable instructions and code.
Next step: Treat a conflict or a change in appliance model as a reason to recheck the whole height calculation.
Cabinet, backsplash, ducting, and safety-code requirements
Range hood clearance is one part of a safe installation. The hood’s position must also work with nearby cabinets, the mounting surface, electrical supply, duct route, and locally adopted code. A noncombustible wall finish may protect the wall surface, but it does not cancel the equipment’s required overhead clearance.
Check whether cabinets or trim sit above or beside the cooking appliance. Follow the appliance and hood instructions for combustible materials. Do not assume that tile, stone, or sheet metal behind the range makes a cabinet above it safe at a smaller distance.
Plan the duct route and termination according to the hood instructions and code. Confirm the required electrical supply and provide mounting support as directed. These checks do not change the clearance measurement, but they can affect where the hood can be placed and whether the planned installation is workable.
Makeup air may also apply. Under 2021 IRC Section M1503.6, a kitchen exhaust system capable of exhausting more than 400 CFM requires makeup air, subject to the adopted code and its exceptions. Check whether that code provision applies where you live; local adoption and amendments can differ.
Key takeaway: Confirm the hood’s height along with surrounding materials and installation requirements before closing walls or cabinets.
Cleaning, filter maintenance, and long-term hood protection
Cleaning does not change the required range hood clearance, but regular care helps keep the installed hood working as intended. Follow the hood manual for filter cleaning, replacement parts, and safe cleaning products. Check the hood after installation and during routine maintenance for loose fasteners or changes in its position.
Grease filters collect grease from cooking exhaust. Keep them clean or replace them as the manufacturer directs. Do not remove a required filter or alter the hood to gain more space above the range. If cleaning or repair requires removing the hood, reinstall it at the verified clearance and secure it as instructed.
After installation, recheck the cooking-surface-to-hood measurement, fasteners, and duct connection. Test the hood according to its instructions. If the project needs inspection or AHJ approval, arrange that before use.
Frequently asked questions about range hood clearance
The answers below give a quick starting point, not a replacement for the range and hood manuals. Check the equipment listing and locally adopted code for your installation. When instructions do not agree, stop and ask the manufacturers or the local building official before mounting the hood.
What is the standard clearance for a range hood?
There is no single standard that applies to every range and hood. Follow both manuals and local code.
How do I measure range hood clearance?
Measure vertically from the cooking surface to the hood’s lowest point.
Is 24 inches enough clearance for a range hood?
Only if the range instructions, hood instructions, and applicable code permit that height.
Is 30 inches a universal minimum?
No. It is a common planning figure, not a universal code requirement.
Does a gas range need more clearance than an electric range?
Often the planning range is higher for gas, but the actual requirement depends on the specific equipment and code.
Can a backsplash reduce the required clearance?
No. A noncombustible backsplash does not automatically permit less overhead clearance.
What if the range and hood manuals disagree?
Do not average their measurements or use the lower one. Ask the manufacturers or AHJ for direction.
Does a hood mounted too high still work?
It may capture smoke and grease less effectively. Follow the hood’s stated mounting range.
When is makeup air required?
Under the 2021 IRC, Section M1503.6, systems capable of exhausting more than 400 CFM require makeup air, subject to adoption and exceptions.
Should I recheck clearance after installation?
Yes. Measure from the cooking surface to the hood’s lowest point and verify the hood is secure before use.
