What Size Range Hood Do I Need for a 30 Inch Stove?

For a 30 inch stove, choose a hood at least 30 inches wide, but 36 inches is better for performance.

Calculate CFM based on your stove type: gas needs 100 CFM per 10,000 BTUs, electric needs 100 CFM per linear foot.
Ducted hoods are more effective than ductless; if ductless is required, use high CFM and replace filters often.

How to Measure for a Range Hood on a 30 Inch Stove

Start with the stove width. A 30 inch cooktop needs a hood at least 30 inches wide. Wider hoods, like 36 inches, capture more smoke and steam. Measure the distance from the cooktop to the hood bottom. Gas stoves require 24 to 30 inches of clearance. Electric stoves allow 18 to 24 inches. Check the manufacturer's specs for exact limits.

What CFM Do You Need for a 30 Inch Range?

CFM, or cubic feet per minute, measures airflow. For gas stoves, add up the BTUs of all burners. Divide the total by 100 to get the minimum CFM. A typical 30 inch gas stove has 40,000 BTUs, so you need at least 400 CFM. For electric stoves, use 100 CFM per linear foot of cooktop width. A 30 inch electric range needs 250 CFM.

Best Range Hoods for a 30 Inch Stove by Use Case

For most homeowners, a 30 inch under-cabinet hood works well. The Broan-NuTone 413004 is a classic choice with 400 CFM. It fits standard 30 inch cabinets and has a dishwasher-safe filter. For a wall-mounted look, the Cosmo COS-63175 offers 450 CFM and a stainless steel finish. Owners report it handles heavy frying well.

Ducted vs Ductless: Which Is Better for a 30 Inch Stove?

Ducted hoods vent air outside, removing smoke and odors completely. They perform best for gas stoves and heavy cooking. Ductless hoods recirculate air through charcoal filters. They are easier to install but less effective. For a 30 inch stove, ducted is recommended if possible.

Common Sizing Mistakes and Edge Cases for 30 Inch Stoves

One mistake is buying a hood that's too narrow. A 30 inch hood on a 30 inch stove is the minimum, but a 36 inch hood captures more. Another error is ignoring ceiling height. High ceilings require more CFM because smoke rises and spreads. For ceilings over 8 feet, add 50% to your CFM calculation.

Common questions

What size range hood do I need for a 30 inch gas stove?

For a 30 inch gas stove, choose a hood at least 30 inches wide, but 36 inches is better. Calculate CFM by adding all burner BTUs and dividing by 100. Most 30 inch gas stoves need 400 to 600 CFM.

Is a 30 inch range hood enough for a 30 inch stove?

Yes, a 30 inch hood meets the minimum width requirement. However, a 36 inch hood provides better capture area and is often recommended for heavy cooking.

How many CFM do I need for a 30 inch electric stove?

For an electric stove, use 100 CFM per linear foot of cooktop width. A 30 inch electric range needs about 250 CFM. Add more if you cook frequently or have a high ceiling.

Can I use a ductless range hood on a 30 inch stove?

Yes, you can use a ductless hood, but it's less effective than ducted. It recirculates air through charcoal filters. Choose a model with high CFM and replace filters regularly.

What is the standard height for a range hood above a 30 inch stove?

For gas stoves, the hood bottom should be 24 to 30 inches above the cooktop. For electric, 18 to 24 inches. Check the manufacturer's instructions for exact clearance.

Does a 30 inch stove need a 30 inch or 36 inch range hood?

A 30 inch hood is the minimum, but a 36 inch hood is recommended for better performance. Wider hoods capture more smoke and steam, especially with high-BTU burners.

How do I calculate CFM for a range hood?

For gas, add up all burner BTUs and divide by 100. For electric, multiply the cooktop width in feet by 100. For example, a 30 inch (2.5 ft) electric stove needs 250 CFM.

What happens if my range hood is too small?

A too-small hood won't capture all smoke and odors, leaving your kitchen hazy. It may also be noisy because it works harder. Choose a hood at least as wide as the stove and with adequate CFM.
