Choose a range hood at least as wide as your cooktop. A hood that extends beyond the cooking surface can capture more smoke and grease, as long as it fits your cabinet or wall and follows installation requirements.

For a typical 30 inch stove, start by comparing 30 inch hoods. For a 36 inch cooktop, compare 36 inch models, then check depth, mounting height, cabinet clearance, and vent route before choosing.

What size range hood do you need for your stove?

Choose a hood that is the same width as the cooking surface or wider. Measure the cooktop itself, since the stove body and cooking surface may not have the same width.

A 30 inch hood suits a 30 inch cooktop when the model's actual width and installation clearances fit your kitchen. A wider hood can give you more side coverage, but it must fit the cabinets or wall.

A 36 inch cooktop generally calls for a 36 inch or wider hood. If your kitchen has an over-the-range microwave or a tight cabinet opening, confirm the available width before shopping.

For a 30 inch opening, the COSMO COS-5MU30 measures 29.75 inches wide. Its slim design is meant for under-cabinet installation.

If you're comparing options by width, see our guide to the best 30 inch under-cabinet range hoods. Measure the cabinet opening, not just the cooktop, before deciding.

Should a range hood be wider than the cooktop?

A hood wider than the cooktop can capture more of the cooking plume at the sides. This is useful when your layout allows a larger hood and your installation guide permits it.

Smoke and grease don't rise in a narrow, straight line. They spread as they rise, so a hood that ends exactly at the cooktop edges may catch less from pans near the sides.

For a 30 inch cooktop, a 36 inch hood could provide extra side coverage. The COSMO COS-5MU36 measures 35.25 inches wide, so check its actual width against the cabinet and wall space.

Don't choose a wider model based on width alone. The hood still needs enough depth and the correct mounting height to cover the cooking area.

How do you measure for a range hood?

Measure the cooktop width, cabinet opening, and hood depth before choosing a model. Note any trim, side panels, or cabinets that could limit the fit.

Use a tape measure to check from the left edge to the right edge of the cooking surface. Then measure the clear space where the hood will mount.

Next, compare the proposed hood's width and depth with that space. For example, the Broan-NuTone 4136SF is 36 inches wide and 17.5 inches deep, so compare both dimensions with your cabinet and cooking area.

Also check the mounting height. Our guide to how high a range hood should be above the stove explains why the required distance depends on the hood type and manufacturer instructions.

Does range hood depth affect the size you need?

Yes, depth affects how well the hood covers the front burners. A hood can match the cooktop's width but still sit too far back to capture cooking fumes from pans near the front edge.

Measure from the wall to the front edge of the cooktop, then compare that distance with the hood depth and its installation position. Some models are designed to fit under cabinets with a slim profile, while others extend farther over the cooking surface.

The FIREGAS FGS-USF22A90AC measures 35.3 inches wide and 19.5 inches deep. Check that depth against your counter and cabinet layout, especially if you regularly use front burners.

For a closer look at front-to-back coverage, read how deep a range hood should be. Width and depth work together, so compare both rather than relying on the size printed in a product name.

Does the hood size change with gas or electric cooking?

The hood's width should still match or exceed the cooktop width, whether you cook with gas or electricity. Heat output and installation requirements can affect hood choice, so check the cooktop and hood manuals.

Gas burners may need more airflow than an electric cooktop, depending on burner output and local requirements. Hood width alone doesn't tell you whether the fan can handle your cooking setup.

If you're choosing a hood for gas, see our guide to range hoods for gas cooktops. For airflow, start with how many CFM a range hood needs.

How does venting affect the hood you choose?

Venting affects where air goes after the hood captures it, not the width needed to cover the cooktop. Check whether you can connect to an exterior duct or need a ductless model that recirculates air.

Ducted hoods send air outdoors through a duct. Ductless hoods pass air through filters and return it to the kitchen, so confirm that the model supports the setup you need.

The Broan-NuTone 4136SF is a ductless model with a charcoal filter. It may suit a kitchen where routing a duct outdoors isn't possible.

If you're considering a convertible setup, read what a convertible under-cabinet range hood is. For a ductless option that matches a wider cooktop, compare our 36 inch ductless range hood guide.

What should you check before buying a range hood?

Before buying, confirm width, depth, mounting height, cabinet fit, and vent type. These checks help you avoid choosing a hood that covers the cooktop but can't fit your kitchen.

Check the hood's installation guide for required clearances and duct size. Make sure the cabinet opening has room for the hood and any needed duct connection.

Then match the vent style to your kitchen. The FIREGAS FGS-USF22A90AC is described as convertible between ducted and ductless use, with a charcoal filter included for recirculation.

Review the fan capacity separately from the dimensions. Our guide to whether 400 CFM is enough for a range hood can help you assess airflow needs for your cooking habits.

How do you choose the right range hood size?

Choose a hood at least as wide as your cooktop, then confirm that its depth and mounting position cover the cooking area. Measure both the cooktop and installation space before you shop.

Pick a 30 inch model for a 30 inch cooktop when the actual dimensions fit. Consider a wider hood if you want more side coverage and have enough cabinet or wall space.

For a 36 inch cooktop, compare 36 inch hoods and verify their depth, vent type, and installation clearances. Use our under-cabinet range hood guide to compare the style and mounting details that fit your kitchen.

What size range hood do I need for a stove?

You need a range hood that is at least as wide as the cooktop. Measure the cooking surface and the available mounting space, then compare the hood's width and depth with the installation guide.

Match a 30 inch cooktop with a 30 inch or wider hood, and a 36 inch cooktop with a 36 inch or wider hood. Check the vent route and required mounting height before buying.

Frequently asked questions

Should a range hood be wider than the stove?

A hood should be at least as wide as the cooking surface, and a wider hood can capture more of the smoke and grease that spread beyond the burners. Choose a wider model only if it fits the cabinet or wall and meets its installation instructions and local requirements.

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

A 30 inch hood is the usual width match for a 30 inch cooking surface, but check the actual hood width and your stove's width before ordering. A wider hood may offer more coverage if it fits the available space.

Can I use a 36 inch hood with a 30 inch stove?

Yes, if the 36 inch hood fits the cabinet or wall and can be installed at the required height. The extra width can extend capture area beyond the edges of a 30 inch stove, but confirm clearances and venting needs first.

Does hood depth matter as much as width?

Yes. Width matches the sides of the cooktop, while depth affects how much of the front burners sit under the hood.

Compare the hood's depth with your cooktop and read the installation guide, especially if you often use front burners.
