If you\u2019ve ever stood in the middle of a grease-covered kitchen after a big stir-fry session, coughing through fumes that won\u2019t lift, you know how frustrating a bad exhaust hood setup can be. As someone who sells wall-mounted exhaust hoods, I get way too many questions about this exact topic: \u201cHow far should<\/em> my hood be from my stove? Too high, and it\u2019s sucking nothing; too low, and I\u2019m burning my arms while frying garlic. Help.\u201d Wall Mounted Exhaust Hood<\/a><\/p>\n

<\/p>\n

I get it\u2014this isn\u2019t some arbitrary rule you find on a random forum. It\u2019s the difference between a hood that works and a hood that\u2019s just a fancy shelf above your stove. Let\u2019s break this down, no stuffy engineering jargon, just what actually works in real kitchens, plus tips from people who\u2019ve been designing and selling these things for decades.<\/p>\n

First, let\u2019s talk about why distance matters more than you think. Think of your stove as a tiny, chaotic smoke stack. When you heat oil or water, that vapor doesn\u2019t just rise straight up in a neat line\u2014it mixes with hot air, gets pushed around by the draft from your open window, your ceiling fan, or even the way your oven door swings open. If your hood\u2019s too high, the vapor dissipates into that draft before the fan can catch it. If it\u2019s too low? Well, two big problems: your hood might crash into your pots and pans (I\u2019ve had customers call me crying about chipping a custom wok\u2014no fun), and more importantly, low hoods can pull in too much<\/em> air, creating negative pressure in your kitchen. That might sound technical, but what it means is your furnace or water heater could backdraft, spewing carbon monoxide into your house. Not something to mess around with.<\/p>\n

So, what\u2019s the sweet spot here? Most reputable standards\u2014like the ones from the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and the Kitchen Industry Association\u2014say for standard gas stoves, the distance should be between 24 and 30 inches above the cooktop surface. For electric stoves, it\u2019s a little different: 20 to 24 inches. Wait, why the difference between gas and electric? Let me make that simple. Gas stoves produce more heat, more consistent vapor, and a wider, more robust \u201cheat plume\u201d (that\u2019s the fancy word for the rising air and fumes from your stove). That means you need a little more space to let that plume fully form before the hood pulls it in. Electric stoves heat more slowly, their vapor isn\u2019t as intense, so you don\u2019t need as much room.<\/p>\n

But here\u2019s the thing\u2014those numbers aren\u2019t one-size-fits-all. I\u2019ve had a customer with a commercial-style gas range, like the kind chefs use in restaurants, and 24 inches was too low. The stove\u2019s heat plume was so big, it was hitting the back of the hood\u2019s interior and bouncing right into his face. We had to bump it up to 32 inches, and suddenly it worked perfectly. On the flip side, a tiny apartment electric stove with a compact hood? 20 inches was more than enough\u2014no fumes escaping, no arms burning. So, those are starting points, not hard rules.<\/p>\n

Let\u2019s talk about how to measure this, because so many people get it wrong. It\u2019s not from the bottom of the hood to the bottom of your pots, right? No, it\u2019s from the cooktop surface<\/em>\u2014that flat metal or glass thing where you set your pots\u2014to the very bottom of the hood. That\u2019s the critical measurement. If you have a gas stove, make sure you\u2019re measuring to the surface, not the burner grates. Grates stick up, so if you measure to the grates, you\u2019ll be too high, and that\u2019s where the vapor is actually coming from.<\/p>\n

Now, what factors throw this off? First, the type of hood you have. A ducted hood (the kind that vents outside, not just recirculates air back into your kitchen) works way better at capturing fumes, so you can probably get away with a little more height\u2014no more than 30 inches for gas, 24 for electric. A recirculating hood? It\u2019s weaker, so you want it lower, maybe 22 inches for electric, 28 for gas, to make up for the lower suction.<\/p>\n

Another big one: your cooking style. Do you do light stuff, like boiling water or making toast? You can go higher. But if you\u2019re stir-frying, deep-frying, or making anything that spits grease and fumes? You need the hood as close as safely possible. I had a regular customer who makes Sichuan food every night\u2014super smoky, super greasy. She put her hood at 26 inches, right in the middle of the gas range sweet spot, and said before that, her kitchen walls needed repainting every year. After, it was two years and still no grease spots. That\u2019s the kind of win we love.<\/p>\n

Wait, what about safety? I mentioned that earlier, but it\u2019s worth repeating. If you hang a hood too low\u2014say, below 20 inches for gas\u2014you\u2019re not just annoying yourself. You\u2019re creating that negative pressure I talked about, which can cause combustion appliances to backdraft. For gas stoves, low hoods can also restrict the airflow to the burners, making them burn inefficiently and produce more carbon monoxide. No one wants that. And don\u2019t even get me started on the fire risk\u2014if you have a hood too close and you\u2019re deep-frying, a grease splash could hit the hot hood surface and start a small fire. Been there, seen that, not pretty.<\/p>\n

I also get asked all the time, \u201cCan I just put it as high as possible and crank the fan?\u201d Maybe, but that\u2019s not a great plan. If your hood\u2019s too high, even the strongest fan can\u2019t pull in vapor that\u2019s spread out. It\u2019s like trying to catch a handful of sand with your hand open vs. your hand cupped. If the sand\u2019s scattered, you miss it. If it\u2019s concentrated, you grab it. The heat plume is that concentrated sand\u2014too high, and it\u2019s spread out too much.<\/p>\n

Let\u2019s go through real-world examples, because that\u2019s what people actually care about. Example 1: Small apartment, electric stove, 24 inches wide recirculating hood. Cooktop height is 36 inches from the floor. I\u2019d set the hood bottom at 60 inches from the floor\u2014wait, let\u2019s check that math: 60 minus 36 is 24, perfect. That\u2019s electric, so 24 inches, exactly the sweet spot. Example 2: Family home, 36-inch gas range, ducted hood. Cooktop is 36 inches off the floor. Sweet spot for gas is 24-30 inches, so 60 to 66 inches from floor. If he does a lot of deep-frying, bump it to 60 inches (24 inches above cooktop) for maximum capture. If he mostly bakes and boils, 66 inches (30 inches) is fine. Example 3: Commercial-style 48-inch gas range. Cooktop 36 inches off floor. The standard 30 inches would be 66 inches, but that stove\u2019s plume is huge, so we go to 68 inches (32 inches) to let the plume fully form. No more fumes in the dining room\u2014just what you want.<\/p>\n

What if you already have a hood and it\u2019s not working? Don\u2019t panic. First, check the distance. If it\u2019s 35 inches above gas, that\u2019s too high. Try lowering it by 5 inches and see if that makes a difference. If it\u2019s 20 inches above gas, that\u2019s too low. If you don\u2019t want to redo the brackets, make sure your fan\u2019s on the right speed\u2014most hoods have low, medium, high. If you\u2019re doing heavy cooking, crank it to high. Also, check if your duct is clogged\u2014grease build-up in the duct kills suction. A clean duct can make an old hood work way better.<\/p>\n

As someone who\u2019s been selling wall-mounted exhaust hoods for years, I\u2019ve seen every mistake. The hood that\u2019s mounted so high it\u2019s just a decorative piece. The hood that\u2019s too low, leaving a burn mark on a customer\u2019s wrist when they reach for a wok. The one where the duct was clogged, so even a perfect distance wasn\u2019t helping. The big takeaway here is that it\u2019s not just following a number\u2014it\u2019s matching your hood, your stove, and how you cook.<\/p>\n

If you\u2019re installing a new hood and you\u2019re not sure where to set it, don\u2019t guess. That\u2019s how you end up with a hood that doesn\u2019t do its job. Measure your stove type (gas vs. electric), decide if it\u2019s ducted or recirculating, and use those starting points: 24-30 inches for gas, 20-24 for electric, adjust based on how smoky your cooking gets.<\/p>\n

Hey, quick side note: A lot of people ask if a wider hood is better. Spoiler: Yes, a hood that\u2019s 3 inches wider than your stove on each side will capture more of that heat plume, so you can maybe get away with an extra inch or two of height if you need to. But don\u2019t skimp on the height to save on hood size\u2014distance still matters more than width.<\/p>\n

At the end of the day, the goal of a wall-mounted exhaust hood is to get grease, smoke, and fumes out of your kitchen, not trap them. Get the distance right, and you\u2019ll notice a difference after one good stir-fry. No more wiping grease off your cabinets after every meal, no more coughing while you cook, no more worrying about backdraft or fire risks.<\/p>\n
