Standard Range Hood Size
Most kitchen range hoods should be at least as wide as the cooktop or range below them.
Common range hood sizes include:
Width: 30 inches, 36 inches, 42 inches, and 48 inches
Depth: 18 to 24 inches
For best ventilation performance, many professionals recommend installing a hood that is 3 to 6 inches wider than the cooking surface.
Examples:
• 30-inch range → 30-36 inch hood
• 36-inch range → 36-42 inch hood
⚠️ A hood that is too small may not properly capture smoke, grease, and cooking odors.
Range Hood Installation Height
The bottom of the hood should typically be installed:
24 to 30 inches above an electric cooktop
27 to 36 inches above a gas cooktop
Always follow the manufacturer’s installation guidelines for your specific range hood model.
How to Measure for a Range Hood
Measure the width of the cooktop or range below.
Measure the available cabinet space or wall space above the cooking surface.
Measure the depth of the cabinet above the range to ensure the hood will fit properly.
Check the duct size and vent location if the hood vents outside.
Write measurements using decimals (example: 35.75 inches).
Why Range Hood Size Matters
Choosing the correct range hood size improves ventilation and helps remove smoke, grease, and cooking odors from the kitchen.
If the hood is too small, smoke and grease may escape into the room instead of being captured.
A properly sized hood covers the cooking surface and provides better airflow and ventilation performance.
Choosing the wrong size can reduce ventilation performance or cause installation issues.
