Range Hood CFM Checklist: How To Plan Kitchen Ventilation

Range Hood CFM Checklist

Choosing a range hood is not only about width or style. Airflow matters too.

CFM, short for cubic feet per minute, is one of the main specs people look at when comparing range hoods. The right number depends on the range, the cooking style, the kitchen layout, and how the hood will vent.

Step 1: Start With The Range

Before comparing hoods, confirm:

• Range width.
• Fuel type.
• Burner output.
• Wall or island placement.
• How often high-heat cooking happens.

The range usually sets the ventilation requirement.

Step 2: Match Hood Width To The Range

A hood should usually be at least as wide as the range.

For a 36 inch range, start with a 36 inch hood minimum and consider a wider hood if the layout and cooking style justify it.

Step 3: Confirm Cooking Style

More intense cooking usually needs better capture planning.

Ask:

• Do you sear or fry often?
• Do you cook with multiple burners at once?
• Is the kitchen open to living areas?
• Will the hood need to capture steam and smoke across a larger area?

Step 4: Check Ducting

Airflow is only useful if it can actually exit the home.

Confirm:

• Whether exterior ducting is possible.
• Duct size.
• Duct route.
• Ceiling height.
• Makeup air requirements if applicable.

Step 5: Decide Wall Versus Island

Wall mount hoods usually capture more efficiently than island hoods because the wall helps guide airflow.

Island hoods often need more planning because air can escape on all sides.

Step 6: Think Beyond CFM

CFM is only one piece of the decision.

Also compare:

• Noise.
• Lighting.
• Filter type.
• Cleaning access.
• Mounting height.
• Finish.
• Control layout.

FAQ

What does CFM mean?

CFM means cubic feet per minute and is used to describe airflow.

Do I always need the highest CFM?

Not necessarily. The right airflow depends on the cooking setup, ducting, and kitchen layout.

Is a wider hood always better?

Not always, but a wider hood can help capture more air in some kitchens.

Should I choose the hood before cabinets?

The hood should be planned before cabinets are finalized so ducting and mounting constraints do not get boxed in.
