Ensure your range hood is at least three inches wider than your cooktop on each side.

What size of rangehood do you need?

To properly trap smoke and aromas from the food cooking below, the optimal range hood for your space should be the same width or wider than your cooking surface. Most ranges and vent hoods come in widths of 30″, 36″, 42″, and 48″.

How wide should your range hood be?

Your range hood should be somewhat larger than your cooktop. Remember the 3-inch rule regarding hood dimensions: your range hood should be three inches wider on each side. For example, if your electric cooking surfaces are 30 inches wide, your range hood should be 36 inches wide.

How do you measure the width of your cooktop?

To determine the width, lay a measuring tape around the outside edges of your current cooktop, starting at the right side and ending at the left. To get the depth take a measurement from the front to the rear of the cooktop, including the control panel. Most range hoods are measured in inches, so measure your cooktop using inches, not centimeters.

Can a range hood be smaller than a cooktop?

No. If the range hood is too small, it will not function properly. It will run too long and complete half the work of a larger range hood, clearing out your kitchen half the time. This wastes materials and costs you more money in energy to run appliances that don’t work well in your kitchen.

How high should you mount your hood?

Installing your range hood at the right height above the top of the stove lets the vent move air and get rid of grease and smells as quickly as possible. The best way to choose the right height for your range hood is to follow the manufacturer’s installation instructions. However, some basic clearance criteria exist.

Electric ranges or cooktops typically require 24″ between the cooktop surface and the range hood, while gas ranges or cooktops require 27″. No matter your range, the distance between the cooktop’s surface and the start of the range hood should be no more than 36″.
