Range Hood Sizes: Find The Right Fit for Your Kitchen

Range hoods help clear away the grease, smoke and odors that linger in the air as culinary creations come to life, reducing cooking odors. Finding the right range hood height and depth for your kitchen helps smoke, odors and grease work their way into the vent and out of your home.

What are Standard Range Hood Dimensions?

Range hood dimensions most often measure 24”, 30” or 36” in width, but can span anywhere from 24” to 60” wide. It’s best to install a hood that measures the same size as your cooktop to most effectively capture the grease, odors and smoke coming from any burner or element below.

Types of Range Hoods to Choose From

Range hoods come in a variety of configurations, so you’re likely to find one that suits your kitchen and empowers your greatest creations. Any hood you consider will either be ducted, sending captured air through a duct to the outside of your home, or recirculating, pulling air through a filter and pushing it back into the kitchen. Learn more about the six different range hood styles below to help you decide which hood would best complement your kitchen's style and cooking habits.

What Size Range Hood Do I Need?

The best range hood size for your kitchen depends on the dimensions of your cooktop and the available space above your cooktop for installing your hood. The ideal range hood for your space should match the width of the cooking surface to make sure it effectively catches smoke and odors from the dishes cooking below. Most ranges and vent hoods are available in 30", 36", 42" and 48" widths.

Choosing the right range hood for your kitchen also means taking CFM and BTU ratings into account. CFMs, or cubic feet per minute, measure the venting strength of your range hood and tell you how much air your vent can suck up in one minute. The higher the CFM rating, the more powerful the vent. BTUs, or British Thermal Units, let you know how hot and high of a flame your vent can handle coming from a gas burner below. For proper venting, be sure to find a range hood with a BTU rating that matches or exceeds the BTU output from your range.

How Do I Measure Range Hood Height and Depth?

Finding the right fit for your range hood requires jotting down a few important dimensions. To get an idea of the space you have to work with, start by measuring the cooking surface, then move on to measuring the area between the cabinets, the height above the cooking surface and the depth of the cooking surface. Work your way through the steps below to gather exact measurements for your range hood.

Step 1: Measure the Width of Your Cooking Surface

Using a measuring tape, find the width of your cooking surface by starting from one side of the cooktop and running the measuring tape straight across to the opposite side of the cooktop. Be sure the tape is running parallel to the cooktop’s front edge to get the most precise measurement.

 

Step 2: Measure the Width of the Area between the Cabinets

Measure the available space between cabinets by securing the measuring tape on one side of the cabinet cavity above the cooktop, then extend the measuring tape straight across to the opposite side, being sure to keep it parallel to the cooktop surface.

 

Step 3: Measure the Height of the Space Above the Cooking Surface

Measure the available space above the cooking surface by securing the measuring tape at the base of the cabinets or ceiling above the cooktop, then extend the measuring tape straight down until it reaches the cooktop surface. Keep in mind that, once installed, there should be anywhere from 24 to 36 inches of space between the bottom of the range hood and the cooktop surface.

 

Step 4: Measure the Depth of the Cooking Surface

To measure the depth of the cooking surface, secure one end of the measuring tape at the back end of the cooktop, excluding the control panel and trim, then extend the measuring tape to the outside edge of the cooktop surface.

How Much Space Should There Be Between My Range Hood and Cooktop?

Every range hood is different, and the installation manual for your hood should specify a minimum and maximum distance for installation. Some typical clearances suggest a minimum of 24 inches of clearance above an electric range or cooktop, and 27 inches above a gas range or cooktop.

How Do I Determine if My Current Range Hood Vent Size is Too Small or Too Large?

Well-suited range hood vents can clear the right amount of grease, smoke and odors from your kitchen. The ideal hood vent for your space should be the same width as your cooktop and deep enough to sufficiently cover both back and front burners.
