Choosing the correct size range hood is one of the most important steps when designing a kitchen. The hood must capture smoke, grease, and odors while still fitting visually within the space.

Width Guidelines
The hood should be the same width as the cooktop or slightly wider to capture smoke, grease, and odors effectively.
Typical pairings:
- 30-inch cooktop → 30-inch or 36-inch range hood
- 36-inch cooktop → 36-inch or 42-inch range hood
- 48-inch cooktop → 48-inch range hood or larger

Does a Range Hood Need to Be Wider Than the Cooktop?
In many kitchens, the range hood should be at least as wide as the cooktop, but many designers recommend choosing a hood that is 3 to 6 inches wider. A slightly wider hood improves smoke capture and ventilation performance.
Choosing a slightly wider hood improves airflow capture and helps prevent smoke and grease from escaping into the kitchen.
For example:
- A 30-inch cooktop often pairs well with a 36-inch hood
- A 36-inch cooktop may benefit from a 42-inch hood
