High-output setup. You'll want a powerful insert and short, straight ducting. Let our team confirm the liner and duct size before you order.

Great news — this is a solid match. This is an estimate; duct length, bends, and ceiling height affect real-world airflow. Confirm with our team before ordering.

How Sizing Works

Three things decide your CFM.

The calculator above is built on the same rules of thumb the pros use. Here's what's driving the number.

02
Fuel & BTUs
Fuel & BTUs
Gas and pro-style ranges put out far more heat than electric. A rough gas method: total BTUs ÷ 100 gives a CFM target.
03
Kitchen & ducting
Kitchen & ducting
Island hoods and long duct runs lose airflow, so they need more power. Ceiling height and bends in the duct matter too.

Ducted vs. Ductless

Where does the air go?

Recommended

Ducted (vented outside)

Air — along with heat, grease, and odors — is exhausted outside through ductwork. This is the most effective option and what we recommend wherever it's possible.

  • ✓Best capture & air quality
  • ✓Removes heat and moisture from the home
  • ✓Ideal for gas and high-BTU cooking
When ducting isn't possible

Ductless (recirculating)

Air passes through a charcoal filter and returns to the room. A practical fallback for apartments or interior walls where outside venting isn't an option.

  • ✓No exterior duct required
  • ✓Easier retrofit installs
  • ✓Filters need periodic replacement
Frequently Asked Questions

Sizing questions?

It's a solid starting point based on standard sizing rules. Real-world airflow also depends on duct length, the number of bends, and ceiling height — so treat the result as guidance and confirm the final spec with our team.
Yes — a hood that's about 3–6″ wider than your cooktop on each relevant side captures smoke and steam more effectively. The tool suggests a width based on your cooktop measurement.
A ductless (recirculating) setup filters and recirculates the air — a good fallback for apartments or interior walls. Reach out and we'll help you choose the right insert for a ductless install.
Gas burners release far more heat and combustion byproducts than electric or induction elements, so they need more airflow to clear the air effectively. Pro-style ranges with high BTUs need the most.
Generally, yes. Island installations are exposed to air movement on all sides and often have longer duct runs, so they typically need higher CFM than a wall-mounted hood over the same cooktop.
Of course. Call us or schedule a video chat and we'll size your vent, match it to a hood, and confirm the fit before you order.
