How to Measure Kitchen Hoods


Range hoods these days not only add a great style element to your kitchen, they also provide a good air-filtration solution that removes harmful smoke, grease, heat and moisture. They are also available in a variety of styles and shapes to suit any taste, regardless of your kitchen area size and set up. But, when choosing the best ventilation system for your kitchen, you have to consider more than just performance, features or a flashy design. One of the most important aspects is selecting the correct size for your specific needs and home.

Selecting the Perfect Size

While considering the sizing aspect, there are three things to keep in mind:  height, width and depth. These specifications are all very important to ensure that the range hood will do its work in an efficient manner.

Determining the Ideal Height

For deciding the proper height, the first thing you have to do is to measure how much space you have above your range. As most manufacturers recommend, the height of a hood from your range top should vary somewhere between 18 to 30 inches, so that it will provide sufficient space to allow you to cook while also capturing steam and fumes efficiently. Usually ducted under cabinet hoods require less distance, but for wall mount or island hoods it’s a good idea to have them placed at most 30 inches above the range.  This depends on the manufacturers specifications.

Choosing the Proper Width

Range hoods come with a wide variety of width sizes, the most popular of which are 30″, 36″, 42″, 48″, 54″, 60″ and 66″. But while selecting, the most important rule to follow is that the range hood should be wider than your cooking range. This increases the hood’s capturing area and helps make for adequate ventilation. When we say wider, we mean about three to six inches wider on both sides. If your kitchen set up doesn’t permit this, then at the very least you should ensure that the width is not less than your range top. However, in case of island range hoods, that extra 3 to 6 inches of overlap is actually needed and essential because of the extra draft within the room. By following these rules you can maximize the performance of your range hood.

Selecting the Right Depth

Now turning to depth, the appliance should be sufficiently deep so that it will cover the entire range cooking surface, including all stove top burners. For under cabinet range hoods the standard depth varies between 19-1/2″ and 21″. The wall-mount hoods usually come with a depth of 24″. Finally the Island hoods are typically available with a depth of 27″ for home cooking and 30″ for professional cooking ranges.

Not something to overlook

It’s very important to keep size in mind when buying a range hood, otherwise it won’t perform nearly as efficiently as it is designed to. Capture area is also one of the most important attributes of any range hood, and it’s directly determined by a hood’s width. In closing, be sure that any range hood you purchase has a larger width than your actual range and also follow the above sizing tips.
