If you're a food-lover like me, you know nothing beats a home-cooked meal. From searing the perfect rib-eye to simmering a fragrant curry, there's a certain joy that comes with pottering around your kitchen. However, an often overlooked hero here is your kitchen ventilation hood. In case you're asking, "What size should my kitchen ventilation hood be?" don't fret. I've got you covered.

The Basics

Before we go into depth, let's cover the basics. In essence, your kitchen ventilation hood is a device containing a mechanical fan that hangs above the stove or cooktop in the kitchen. It removes airborne grease, combustion products, fumes, smoke, heat, and steam from the air by evacuation of the air and filtration.

Now that we've got that out of the way, let's delve into the nitty-gritty – how big should your kitchen ventilation hood be?

The Magic Formula For Sizing

You've probably heard all kinds of suggestions on this. However, it's as much a science as it is an art. As a veteran repairman turned DIY guru, I recommend the golden rule - your hood should have a width equal to or greater than the cooking surface it’s set above. If it's too small, it won't effectively remove all the airborne particles, leaving you with unwanted smoke and smells. Conversely, if it's too big, it will capture the smoke, but also your favourite fruit bowl.

To aid you in your selection, consider your hood's CFM (cubic feet per minute) rating. This measures the volume of air the hood vent can move per minute. A pro tip here - For every 100 BTU (British Thermal Units) of your cooktop, you require 1 CFM. So, a cooktop with 30,000 BTU calls for a vent hood capable of moving 300 CFM.

Taking Into Account Your Kitchen Size

Of course, the size of your kitchen plays a significant role. Picture this - you probably wouldn’t put the same size hood in a cozy apartment kitchen that you would in a expansive home kitchen, right?

Here's a fun piece of trivia- according to the Home Ventilating Institute, your hood should be capable of attaining 15 air changes per hour. Here's where our ol' pal math comes in. Divide your kitchen's volume (length x width x height in feet) by four to obtain the minimum CFM your hood should be capable of.

Shape Of The Hood

Remember, all hood styles are not created equal. When it comes to capturing all that airborne mess, a hood with a larger capture area - the open area that faces the cooktop - will do a better job than one with a smaller area. So, bigger might indeed be better!

Installation Height Hacks

Now that you've figured out the right size, wondering how high to hang them? Ideally, a hood should be installed 24-30 inches above the cooktop. Note though that if you're using a pro-style or high-BTU range, you might require a larger hood height.

In Summation…

While it may not be as thrilling as choosing your oven, getting the right size of kitchen ventilation hood is crucial. Remember to size them according to your cooktop, taking into account your kitchen's size and the hood's CFM rating.

Final Words from the Workbench

There you have it, folks! Sizing your kitchen ventilation hood need not be a complex task. Using these guidelines, you can ensure your kitchen stays fresh and appetizing, no matter what you're cooking. Remember, it's not just about cooking; it's also about enjoying the process. So, go ahead and simmer that curry or sear that steak without any fear. Your trusty ventilation hood has got your back!
