Standard Range Hood Height and Why It Matters

A range hood should sit 24 to 30 inches above the cooking surface of your stove. This is the distance measured from the top of your burners (or cooktop) straight up to the bottom of the hood. Most building codes and appliance manufacturers specify this range because it balances two competing needs: capturing steam and cooking odors before they spread through your kitchen, and staying far enough away that you won't hit your head or accidentally touch a hot surface while cooking.

If your hood is too low, you risk bumping into it, and grease buildup happens faster because the hood pulls air too aggressively from the cooking surface. If it's too high, the hood loses suction and won't pull smoke and steam away effectively—you'll smell cooking odors throughout your home instead of just at the stove.

The exact height you choose within that 24 to 30 inch range depends on your ceiling height, the type of hood you have, and how tall you are. Taller cooks often prefer the upper end of the range to avoid head bumps during normal cooking.

Key Takeaways

  • Range hoods should be mounted 24 to 30 inches above the cooking surface, measured from the top of your burners to the bottom of the hood.
  • Hoods mounted below 24 inches create a burn or bump hazard and pull grease too aggressively onto the hood itself.
  • Hoods mounted above 30 inches lose suction power and won't remove cooking odors and steam from your kitchen effectively.
  • Island hoods and wall-mounted hoods follow the same height rule, though island hoods sometimes sit slightly higher because they're more visible in the room.
  • If your ceiling is very low or your stove is unusually tall, work with the 24 to 30 inch range as closely as possible rather than guessing.

How to Measure and Mark the Correct Height

Start by identifying the highest point of your cooking surface. On a gas stove, this is the top of the grates when they're in place. On an electric cooktop, it's the flat surface of the burners. On a smooth-top electric range, it's the glass surface itself. Measure straight up from that point.

Mark the wall or mounting location at 24 inches, then again at 30 inches. Stand at the stove and look at those marks. If you're tall or cook frequently, the 28 to 30 inch range will feel more comfortable. If you have a small kitchen or low ceiling, 24 to 26 inches may be your only option—but stay within the range if possible.

Before you drill or mount anything, double-check that your ductwork can reach from the hood to your exterior wall or roof vent without too many bends. Long, kinked ducts reduce suction just as much as mounting the hood too high does.

Wall-Mounted Hoods vs. Island Hoods

A wall-mounted hood (also called a range hood or under-cabinet hood) hangs directly above the stove and follows the 24 to 30 inch rule strictly. These are the most common type and the easiest to install at the correct height because the wall gives you a clear vertical line to measure.

An island hood hangs from the ceiling above a stove that sits in the middle of the kitchen, away from walls. Island hoods often sit at the higher end of the range—28 to 36 inches—because they're more visible in the room and taller clearance looks better aesthetically. However, they still need to be close enough to pull steam and odors effectively. Check your hood's manual for the manufacturer's recommendation, as some island models are designed for slightly different heights than wall-mounted versions.

Both types need the same suction to work properly, so don't assume an island hood can sit higher just because it looks better there. Test the hood's performance after installation by turning it on while cooking; if you still smell strong cooking odors in other rooms, the hood is too high.

What Happens If Your Hood Is Installed at the Wrong Height

A hood that's too low creates several problems. You or anyone cooking in your kitchen may bump their head, especially if you're tall or reaching across the stove. The hood pulls grease and moisture directly off the cooking surface, which means more grease accumulates on the hood's underside and filters faster. You'll need to clean or replace filters more often, and the hood itself becomes a maintenance burden.

A hood that's too high loses suction because the distance is too great for the fan to pull air effectively. Cooking smells linger in your kitchen and drift into other rooms. Steam from boiling water or pasta doesn't get pulled away, so it condenses on your ceiling and walls instead. Over time, this moisture can damage paint, drywall, and cabinets.

If you've already installed a hood at the wrong height, you have options. If it's too high, you can sometimes lower it by adjusting the mounting brackets or shortening the duct run (if the ductwork allows). If it's too low and you can't move it, a professional installer can sometimes relocate it—this is worth the cost if the hood isn't working properly.

Accounting for Cabinets and Trim

If you have cabinets above your stove, measure from the cooking surface, not from the top of the cabinets. The hood should still sit 24 to 30 inches above the burners themselves. Many kitchens have a cabinet or soffit directly above the stove; the hood mounts to that cabinet or to the wall behind it, and the measurement stays the same.

Some hoods come with a trim ring or flange that sits flush against the wall or cabinet. This trim doesn't change the height calculation—you still measure from the burners to the bottom of the hood itself, not to the trim ring.

If your kitchen has very low cabinets or a soffit that's close to the stove, you may not have room for a traditional under-cabinet hood. In that case, a downdraft hood (which pulls air down into the countertop instead of up) or a pop-up hood (which rises when in use) might work better. These follow different installation rules, so check the manufacturer's instructions.

Ductwork and Venting Considerations

The height of your hood affects how your ductwork runs. A hood mounted at 24 inches leaves less vertical space above it before the duct has to turn and run horizontally toward the exterior wall or roof. A hood at 30 inches gives you more room for the duct to rise slightly before turning, which actually improves airflow.

Ducts should slope slightly upward as they run away from the hood (about 1/4 inch per foot of horizontal run). If your hood is very low and your ductwork has to make a sharp turn when ready, the duct may not slope correctly, and grease can pool inside the duct instead of draining back to the hood.

If you're venting through the roof, a hood at 30 inches gives the duct a straighter path upward. If you're venting through an exterior wall, the height matters less as long as the duct slopes correctly. Either way, avoid ductwork with too many bends or sections that are too long—these reduce suction and make the hood work harder.

When to Call a Professional Installer

If your stove is an unusual height, your ceiling is very low, or your kitchen layout makes standard mounting difficult, a professional installer can help you find the best compromise. They can also assess your ductwork and make sure the hood will actually pull air out of your kitchen instead of just recirculating it.

If you're replacing an old hood and the new one is a different size or type, the mounting height may need to change. A professional can verify that the new hood will work at the height where the old one sat, or adjust the installation if needed.

Most range hood installations are straightforward enough for a handy homeowner to handle, but if you're unsure about electrical connections, ductwork, or structural mounting, hiring an installer is worth the cost. A poorly installed hood won't work well and may create safety issues.

Frequently Asked Questions

Can I install my range hood higher than 30 inches if my ceiling is very high?

You can, but the hood's suction will weaken the higher it sits. Stay within the 24 to 30 inch range if possible. If your ceiling forces you higher, choose a hood with a more powerful fan (measured in CFM, or cubic feet per minute) to compensate. Check the manufacturer's recommendations for your specific model.

What if my stove is taller than a standard 36-inch range?

Measure from the highest point of your cooking surface, not from the stove's frame. A commercial-style range or a raised cooktop may sit higher than standard models. Maintain the 24 to 30 inch distance from the actual burners or cooktop surface to the hood's bottom.

Do I need to leave extra space above the hood for ductwork?

No. The 24 to 30 inch measurement is from the burners to the bottom of the hood. Ductwork connects to the top or back of the hood and runs above or behind it. You don't add extra space for the duct—it straightforward attaches to the hood at whatever height the hood is mounted.

Can I use a recirculating hood if I can't vent to the outside?

Yes, though recirculating hoods (which filter and return air to the kitchen instead of venting it outside) are less effective than ducted hoods. They still need to sit at 24 to 30 inches above the stove to capture steam and odors. Recirculating hoods require regular filter changes and won't remove moisture as well as a ducted hood.

What's the difference between the height for a gas stove and an electric stove?

There is no difference. Both gas and electric stoves use the same 24 to 30 inch range. Measure from the top of the grates (gas) or the cooktop surface (electric) straight up to the hood's bottom. Gas stoves produce more heat, but that doesn't change the safe or effective mounting height.
