Enter the cooktop height and the recommended distance between the cooktop and range hood into the calculator to determine the proper height at which to install your range hood.

Range Hood Height Formula

The following formula is used to calculate the range hood height.

RHH = CH + RD

Variables:

  • RHH is the range hood height (inches)
  • CH is the cooktop height (inches)
  • RD is the recommended distance between the cooktop and the range hood (inches)

To calculate the range hood height, add the cooktop height to the recommended distance between the cooktop and the range hood.

What is Range Hood Height?

Range hood height is the distance from the cooktop to the bottom of the range hood. It is important to install the range hood at the proper height to ensure effective ventilation of smoke, steam, and cooking odors from the kitchen. The recommended distance can vary based on the range hood manufacturer and the type of cooktop (gas or electric), but it typically ranges from 20 to 30 inches above the cooktop.

How to Calculate Range Hood Height?

The following steps outline how to calculate the Range Hood Height.


  1. First, measure the height of the cooktop from the floor (CH) in inches.
  2. Next, determine the recommended distance (RD) between the cooktop and the range hood in inches. This information can usually be found in the range hood’s installation manual.
  3. Use the formula RHH = CH + RD to calculate the range hood height (RHH).
  4. Finally, install the range hood at the calculated height above the cooktop.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Cooktop height (CH) = 36 inches

Recommended distance (RD) = 24 inches
