Standard Range Hood Height: 24 to 36 Inches

A range hood should sit 24 to 36 inches above the cooking surface of your stove. This is the distance from the top of your burners (or cooktop) straight up to the bottom of the hood. Most building codes and appliance manufacturers use this range because it balances two competing needs: capturing steam and cooking odors before they spread, and staying far enough away that you won't hit your head or catch your hair while cooking.

The exact height within that range depends on your hood type and your stove's power. A standard wall-mounted hood over a gas range often works best at 30 inches. An island hood (one hanging from the ceiling) usually needs to be slightly higher, around 30 to 36 inches, because it has to pull air from all sides. Downdraft systems built into the countertop sit much lower, sometimes just 3 to 6 inches above the cooking surface, because they pull air downward instead of up.

If you install your hood too low, you risk burns or fire if you use tall pots or have a gas flame that reaches higher than expected. If you install it too high, the hood loses suction power and won't capture grease and steam effectively—you'll notice cooking smells lingering in your kitchen and grease buildup on your cabinets and walls.

Key Takeaways

  • Measure 24 to 36 inches straight up from the top of your burners to the bottom of the hood, not from the countertop.
  • Wall-mounted hoods typically work best at 28 to 30 inches; island hoods at 30 to 36 inches.
  • Gas stoves often need the hood slightly higher than electric stoves because gas flames can reach taller.
  • Installing a hood too high reduces suction and leaves cooking odors and grease in your kitchen; too low creates a burn or fire hazard.
  • Check your hood's manual for the manufacturer's recommended height, as some models have specific requirements.

Why Gas and Electric Stoves Need Different Heights

Gas burners produce a visible flame that can reach 12 inches or higher, depending on the burner size and how high you turn it. Because of this, most building codes recommend mounting a hood at least 30 inches above a gas cooktop. If you place it lower, a tall flame from a large pot can come dangerously close to the hood's underside, risking burns or damage to the hood's motor and filters.

Electric coil and smooth-top ranges don't have an open flame, so the heat rises more gradually and predictably. You can often place a hood at the lower end of the range—24 to 28 inches—over an electric stove without losing much suction. However, many installers still use 30 inches as a standard for both types to keep the installation straightforward and consistent.

Induction cooktops, which use magnetic energy to heat cookware directly, produce very little steam or rising heat compared to gas or electric coils. Some homeowners find they can go slightly lower with an induction stove, but 28 to 30 inches remains the safest choice.

Measuring and Installing at the Correct Height

Start by identifying the highest point of your cooking surface. For a gas range, this is the top of the burner grates. For an electric coil range, it's the top of the coils. For a smooth-top or induction cooktop, it's the surface itself. Measure straight up from that point—not from the countertop, which can be misleading if your stove sits in a recessed area or on a raised platform.

Use a tape measure and a level to mark where the bottom of the hood will sit. Mark this height on the wall or ceiling with a pencil before you drill any holes. Double-check the measurement from multiple points across the stove, because cooktops are not always perfectly level. If your measurement varies, use the highest point as your reference—this ensures the hood won't be too low anywhere above the stove.

Before you install, read the manual that came with your hood. Some models have a specific recommended height, and a few high-powered commercial-style hoods may require 36 inches or more. If you're installing over an island, make sure you have enough clearance above the hood for air to escape into your ductwork or for a filter to be removed and cleaned without hitting the ceiling.

Common Mistakes That Affect Hood Performance

The most frequent error is measuring from the countertop instead of from the cooking surface itself. If your stove sits on a base cabinet and your countertop is 36 inches high, measuring 30 inches up from the counter puts your hood at 66 inches total—far too high. Always measure from the burners or cooktop surface.

Another mistake is installing the hood too high to save headroom or to fit it between upper cabinets. A hood at 40 or 48 inches above the stove will barely pull any steam or odor, and you'll end up with grease on your walls and cabinets. If headroom is tight, consider a lower-profile hood or a downdraft system instead of compromising on height.

Some people also forget to account for the thickness of a new countertop if they're replacing it. If you're installing a hood before the new countertop goes in, measure from where the new cooking surface will be, not from the old one. Miscalculating this can leave your hood inches too high or too low once the work is done.

Island Hoods and Special Situations

An island hood hangs from the ceiling and must pull air from all directions around the stove. Because of this, it typically needs to be higher than a wall-mounted hood—usually 30 to 36 inches above the cooking surface. The extra height helps air flow up and around the hood without creating dead zones where steam escapes to the sides.

If you have a very tall ceiling or a large island, you may need a hood with higher CFM (cubic feet per minute) rating to maintain suction at that distance. Check the hood's specifications to see what height range it's designed for. Some island hoods are rated for 24 to 36 inches; others work best at 30 to 42 inches.

For under-cabinet hoods mounted directly to the wall cabinets above your stove, the height is usually fixed by the cabinet position. If your cabinets are too high, you may need to remove them and remount them lower, or switch to a wall-mounted hood that can be positioned independently. Downdraft systems offer another alternative if you can't achieve the right height with a traditional hood.

Ductwork and Venting Considerations

The height of your hood affects how you route the ductwork. A hood mounted at 30 inches leaves more room to run ducts horizontally through walls or up through the ceiling to an exterior vent. If your hood is very high, you may need longer ducts, which can reduce suction if they're not sized correctly.

Ducts should slope slightly upward as they move away from the hood (about 1/4 inch per foot) to help grease and moisture drain back toward the hood. If your ductwork has to make tight turns or long runs because of hood height, you may lose suction and efficiency. When planning your installation, think about where your exterior vent will be and whether the hood height makes the ductwork path practical.

If you're venting through a wall to the outside, a hood at 30 inches usually allows you to run ducts through the wall cavity without major structural changes. Venting through the roof or a long horizontal run may require larger-diameter ducts to compensate for the distance and turns.

Frequently Asked Questions

What if my kitchen has a low ceiling and I can't fit a hood at 30 inches?

If your ceiling is very low, consider a downdraft or updraft system that pulls air down into the cooktop or countertop instead of up. These sit much lower and can work in tight spaces. Alternatively, a thin under-cabinet hood mounted directly to wall cabinets may give you the height you need without taking up extra space.

Can I install a range hood lower than 24 inches?

No. Installing a hood lower than 24 inches creates a serious burn and fire hazard, especially with gas stoves. It also reduces suction significantly. If you have space constraints, choose a different ventilation type rather than lowering a traditional hood below the minimum safe height.

Does a more powerful hood need to be higher or lower?

A more powerful hood (higher CFM rating) can actually work at a slightly greater distance because it pulls harder. However, it should still stay within the 24 to 36 inch range for safety and to avoid creating uncomfortable drafts. Check your hood's manual for its specific recommended height range.

How do I measure if my stove is at an angle or not level?

Use a level to check if your cooktop is truly horizontal. If it slopes slightly, measure from the highest point of the cooking surface. This ensures the hood won't be too low anywhere above the stove. If the slope is severe, have the stove releveled before installing the hood.

Should I measure to the hood's bottom or to the edge of the hood's frame?

Measure to the lowest point of the hood itself—usually the bottom edge of the metal or glass panel. Do not measure to the frame or mounting brackets. This gives you the true clearance between your cookware and the hood.
