A range hood should be deep enough to cover your cooktop from front to back, especially the front burners. Measure the cooking surface and compare it with the hood's usable depth, then follow the hood and range instructions for mounting and clearance.

The right depth depends on your cooktop, cabinet layout, and where the hood sits above the burners. A slim hood can save cabinet space, but it may leave the front of a deep cooking surface less covered.

How deep should a range hood be for your cooktop?

Choose a hood whose front-to-back coverage reaches across the cooking surface. For a practical fit, compare the cooktop's depth with the hood's depth and check that the front burners don't sit beyond the hood's effective capture area.

Measure the cooktop from its back edge to its front edge, including any part that extends past the counter. Then measure the hood from the wall side to its front edge.

Use the manufacturer's installation instructions to confirm which part of the hood counts as usable coverage.

Depth is only one part of fit. A hood's mounting height, width, fan, and ventilation setup also affect whether it suits your kitchen.

Our guide to what size range hood you need covers how to compare hood width with your range.

How do you measure range hood depth?

Measure from the wall or rear mounting edge to the front lip of the hood. Check the product dimensions and installation diagram, since a control panel, curved edge, or decorative trim may make the visible front edge different from the usable hood area.

Measure your cooktop in the same direction, from back to front. If the range sits close to a wall, note where the rear burners and front burners fall in relation to the hood.

Also measure the cabinet's depth and the space available below it. A hood may project past the cabinet front, but that arrangement must fit the hood design and installation instructions.

How deep is a standard under-cabinet range hood?

There isn't one depth that suits every kitchen. The models below range from 13.39 in to 22 in deep, so compare the actual dimensions with your cooktop and cabinet before deciding.

These are examples, not a universal depth standard. Your cooktop measurements and the hood's installation guide should decide the fit.

How much hood depth do front burners need?

The front burners deserve close attention because they sit nearest the edge of the cooking surface. If they extend past the hood's front edge, rising steam and grease can miss some of the hood's capture area.

Look at your range from the side and note how far forward the front burners sit. Compare that position with the hood's front edge after accounting for the planned mounting height.

If the hood can't cover the front burners well, consider a deeper model or a design that projects farther forward. Don't move a hood lower or closer to the range to compensate unless both appliance manuals allow that mounting position.

For more on vertical placement, read how high a range hood should be above the stove. Height and depth work together, so check both before choosing.

Can a shallow range hood still work?

A shallow hood can work when it covers the cooking area well and suits the installation. It may fit better under a low cabinet, but a short front-to-back reach can leave the front burners less covered.

The CIARRA CAS75918A measures 13.39 in deep and has a slim profile. Its 30 in width, mesh filters, and convertible ducted or ductless setup may suit some compact installations, though its depth should be checked against your range.

The hood can be ducted or used in ductless mode with an optional CACF006 carbon filter. Choose the ventilation setup that matches your kitchen and the instructions for your hood.

If you need a low-profile fit, compare more options in our guide to low-profile range hoods for tight spaces. A slim shape by itself doesn't confirm that the hood covers your burners.

When might a deeper hood make sense?

A deeper hood can make sense when your cooktop has a deep surface, the front burners sit near the front edge, or your cooking style creates fumes toward the front. It still needs to fit below the cabinet and meet the installation instructions.

The Hauslane UC-PS18 measures 22 in deep and offers three venting options: vertical 6 in round, vertical 3¼ x 10 in rectangular, or horizontal 3¼ x 10 in rectangular. Check whether its deeper body and duct adapters suit your cabinet and existing ductwork.

A deeper hood may project beyond the cabinet face, so check for nearby doors, shelves, and head clearance. Don't assume a deeper hood is always the better fit if it would interfere with the kitchen layout.

Does range hood depth affect ducting?

Depth affects the hood's physical fit, while the duct route determines how air leaves the kitchen. Check both before buying, especially if the cabinet contains an existing duct opening or the hood must vent through a wall.

The Broan-NuTone BCSQ130SS measures 19.63 in deep and supports several installation configurations, including ducted and non-ducted recirculation. Its recirculating setup requires a separate filter, so confirm which configuration you plan to use.

The Hauslane UC-PS18 includes adapters for its three venting options. The CIARRA CAS75918A can be ducted or used in ductless mode with an optional carbon filter.

For a closer look at installation choices, read how to replace an under-cabinet range hood. If you're weighing ducted and recirculating setups, our guide to convertible versus ducted range hoods explains what changes.

What should you check before choosing a hood depth?

Check cooktop depth, front-burner position, cabinet depth, mounting height, and duct route. Compare the hood's dimensions with each one, then use the installation instructions to confirm the model fits.

A quick measuring check can catch common mismatches:

1. Measure the cooktop from back to front.
2. Note how far the front burners sit from the cooktop's front edge.
3. Measure the hood depth and cabinet depth.
4. Check the planned mounting height against both appliance manuals.
5. Confirm the duct opening or recirculating setup matches your kitchen.

Don't use a hood's width as a substitute for depth. The two measurements cover different parts of the cooking surface.

Which hood depth should you choose?

Choose a depth that covers the full cooktop, including the front burners, while fitting your cabinet and the required mounting position. A 13.39 in hood may help in a tight space; a 19.63 in or 22 in model gives you more front-to-back depth to compare with your range.

If you're still unsure, measure the cooktop and cabinet before comparing models. Then read what size range hood you need and check the height guidance for mounting a hood above the stove.

Frequently asked questions

How deep should a range hood be?

Choose a hood deep enough to cover your cooktop from front to back, with particular attention to the front burners. Measure the cooktop and compare it with the hood's actual depth, then check the hood and range manuals for installation requirements.

Cabinet shape and mounting height can affect how well the hood captures cooking fumes.

Should a range hood stick out past the cabinets?

It can extend beyond the cabinet face if the hood's design and installation instructions allow it. What matters is that it covers the cooking area and fits safely under the cabinet.

Measure the hood depth, cabinet depth, and available clearance before choosing a model, and don't assume the cabinet front marks the right hood edge.

Is a 13-inch-deep range hood enough?

A 13-inch depth may suit a shallow cooktop or a tight cabinet space, but depth alone can't confirm coverage. Compare the hood's front-to-back measurement with your cooktop and burner layout.

If the front burners sit well ahead of the hood, consider a deeper design or ask the manufacturer about suitable installation.

Does mounting height affect range hood coverage?

Yes. A hood mounted higher sits farther from cooking fumes, so its depth and width may have less effective coverage.

Follow the range and hood manuals for the allowed mounting height, and compare hood dimensions with the whole cooktop rather than judging by appearance alone.
