Undercounter Refrigerator Dimensions: Sizes, Capacity & How to Measure

Standard undercounter refrigerator sizes

Undercounter refrigerators, beverage centers and wine coolers are built to slide beneath a standard 36-inch countertop. Typical dimensions are:

• Height: about 34 to 35 inches, leaving a little clearance under the counter.
• Width: about 24 inches for standard models; compact models start around 15 inches.
• Depth: roughly 23 to 27 inches, sometimes including the handle.
• Capacity: around 3 cu. ft. for 15-inch models and about 5–6 cu. ft. for 24-inch models.

Cutout vs appliance size

The cabinet cutout (rough-in opening) is usually slightly larger than the appliance itself — often by an inch or less. Exact requirements vary by model, so always check the installation guide for the unit you're considering before you buy.

Where an undercounter fridge works best

• Kitchen islands: a 24-inch unit lines up with many standard island cabinet openings.
• Home bars and coffee stations: keep mixers, cream and drinks right where you use them; interior lighting helps at night.
• Entertaining spaces: dual-zone models let you keep wine and other drinks at different temperatures.
• Apartments and small kitchens: a 15-inch model adds cold storage without a big footprint.
• Basements, rec rooms and guest suites: free up space in your main refrigerator.

How to measure in 5 steps

• 1. Measure the opening: take width, height and depth in several spots — openings aren't always perfectly square.
• 2. Check counter height and floor level: measure from the floor to the underside of the countertop, especially on bar-height islands, and note any uneven flooring the leveling legs must handle.
• 3. Confirm depth and outlet location: most units plug into a standard 3-prong, 120-volt outlet, so plan where the cord will run so the unit can sit fully back.
• 4. Leave room to breathe: many models call for about a quarter inch of clearance on the sides and top — confirm with the installation guide.
• 5. Check the door swing: make sure walls, cabinet handles and walkways won't stop the door from opening far enough to pull shelves out.

Undercounter refrigerator FAQs

Is a 24-inch undercounter fridge the same size as a dishwasher? They're often similar, but clearance, ventilation, plumbing and electrical requirements differ, so they aren't always interchangeable in the same opening.

Do undercounter refrigerators need a water line? Most beverage and wine centers don't. Models with a built-in ice maker do.

What about ADA-height models? ADA-compliant installations may require a lower countertop or adjusted dimensions to meet reach and clearance requirements.
