Buying a range hood for your kitchen? Here is everything you need to know.
Over the years, we have had a lot of different range hoods questions come up at World CopperSmith. This article was created to put an end to the most common project stoppers regarding decorative ventilation. So, if you’re buying a range hood and looking to find Kitchen Nirvana, take a few minutes and read our informative article that should tell you everything you need to know about buying a range hood.
How high above the cooktop should your range be?
Range Hood Max Height?
The maximum recommended Range hood height is 36″ off the cooktop to function properly.
Considering most cooktops are 36″ in height, even if you maxed out most insert fan manufacturers recommendations of 36″ over the cooktop, you would still be at six feet to the bottom of the hood. The secret to making sure your range hood is not on obstruction in the kitchen is the range hood depth, not height. Elect for a range hood depth that is the same or less than your cooktop depth.
How does the height of the range hood effect performance?

This range hood is too high up, and to catch the grease, it would need a bigger canopy. Most insert fan manufacturers tell you what is optimal for their range hoods. We find that 30″ above the cooktop is a good all-around place to start. If you want to go higher, just remember that the smoke and grease will cover a larger area as it rises. You may want to consider going 3″ inches bigger on each side. This also seems to be especially true for island range hoods.
How wide should my range hood be?
We get this question all the time. If your stove is 30″ wide, your range hood can be anywhere from 30″-36″ wide. Stay in this range, and your kitchen will look and perform perfectly!
How tall should my range hood be?
Do I have to go all the way to the ceiling?
Short Answer, No.
How much CFM do I need?
CFM stands for cubic feet per minute.
Standard ventilation systems are 100-400 cfm. This works for customers looking for an average system, and plan to do little to no cooking. They also are compatible with recirclating range hoods.
400-1000 CFM is a semi-professional grade.
Over 100 CFM are considered professional grade and for serious home chefs, outdoor BBQ settings and commercial application. Large CFMs may require makeup air, so you will need to check with your contractor.
