Range Hood Sizing & Selection Guide
A practical guide to choosing the right kitchen range hood. I break down vented vs. unvented designs, under-cabinet vs. full-unit vs. insert hoods, CFM sizing, hood width, and how gas and electric cooking affect what you need.
What This Guide Covers
- Vented vs. unvented range hoods
- Under-cabinet, full-unit, and insert-only designs
- Room-size CFM calculation using Length × Width × Height ÷ 4
- CFM considerations for gas vs. electric / induction cooktops
- How to size hood width using range width plus about 3 inches on each side
- Real-world examples showing how to apply the math
Why It Matters
Range hoods are easy to undersize if you only look at appearance or advertised CFM. This guide is meant to help homeowners match the hood to the room, the cooking appliance, and the installation style before buying.
