Range Hood Buying Guide - Size, CFM and Style

Choosing the right range hood involves three decisions: size, power, and style. Get these right and your kitchen stays fresh, your cabinetry stays clean, and your cooking experience transforms. Here is everything you need to know.

Size Matters Most

Your range hood should be the same width as your cooktop or range, or wider. Never smaller. A 30-inch range needs at least a 30-inch hood. A 36-inch range pairs best with a 36-inch hood. For island installations, go one size up since there are no walls to contain the cooking fumes.

Understanding CFM

CFM stands for cubic feet per minute and measures how much air the hood moves. For standard electric or low-BTU gas cooking, 300 to 400 CFM is sufficient. For serious gas cooking with high-BTU burners, aim for 600 to 700 CFM. For commercial-style ranges or wok cooking, look at 900 CFM and above. A general rule: you need 1 CFM per 100 BTU of cooktop output.

Mount Type

Mount type depends on your kitchen layout. Wall mount hoods install against a wall above your range and are the most common and easiest to install. Island mount hoods hang from the ceiling above a kitchen island and typically need higher CFM since there are no walls to help contain fumes. Under cabinet hoods tuck beneath your cabinetry for a discreet look. Insert hoods fit inside custom cabinetry or a built-in surround.

Duct vs Ductless

Duct vs ductless is another key choice. Ducted installation vents air outside your home and is always more effective. Ductless or convertible hoods use charcoal filters to recirculate air and are ideal when exterior ducting is not possible. Many ZLINE hoods offer convertible operation so you can choose either option.

Style and Finish

Style and finish should match your range. ZLINE offers stainless steel, copper, wood, and the Autograph Edition with gold, bronze, or black accents. Matching your hood finish to your range creates a cohesive kitchen design that looks intentional and premium.
