Measure Twice. Choose the Right Appliance Once.
A practical appliance measurement guide for refrigerators, ranges, wall ovens, cooktops, dishwashers, ventilation, microwaves and room air conditioners.
Start with three measurements—then verify the details.
Measure the finished opening, not the old appliance. Check more than one point because floors, walls and cabinets are not always perfectly square.
Choose what you are measuring.
Open only the appliance you need. Each guide shows what to measure, what to confirm and when expert review may prevent a costly mismatch.
01 — Refrigerators & Freezers
Measure the opening, door swing and delivery route.
Especially important beside a wall or for built-in and panel-ready models.
Measure
- Opening width at the top, middle and bottom
- Height at the left, center and right
- Depth from the rear wall to the cabinet face
- Distance to walls, islands and opposite counters
- Narrowest doorway, hallway, stair and turn
Confirm
- Overall depth with doors and handles
- Depth with doors open and drawer pull-out space
- Hinge-side clearance and required opening angle
- Model-specific ventilation clearances
- Water-line and outlet location, when applicable
Confirm Before Ordering If
- The refrigerator sits beside a wall
- You are changing standard-depth to counter-depth
- It is built-in, integrated or panel-ready
- The delivery route includes tight turns or stairs
- You are unsure about water or ice connections
Doors may need to open past 90 degrees for full bin and drawer access. Compare the exact door-clearance drawing—not only cabinet width.
02 — Ranges & Cookers
Check the opening, counter height, fuel and door clearance.
Changing size or fuel type can change installation requirements.
Measure
- Opening width near the front and back
- Finished-floor-to-countertop height
- Depth from wall to cabinet face
- Clearance in front for the fully open oven door
- Nearby cabinets and combustible surfaces
Confirm
- Freestanding, front-control or slide-in configuration
- Gas, electric, induction or dual-fuel requirements
- Voltage, amperage, receptacle and gas location
- Anti-tip device and model-specific clearances
- Hood width and installation compatibility
Confirm Before Ordering If
- You are changing gas to electric or electric to gas
- You are moving from 30 inches to a wider model
- The range must sit flush with custom cabinetry
- You are pairing a pro-style range with ventilation
- Connection locations may conflict with the range body
Review the complete dimension drawing and connection zone before ordering.
03 — Wall Ovens
Measure the cabinet cutout—not the advertised oven width.
Single, double and combination ovens can require very different cutout heights.
Measure
- Inside cutout width, height and depth
- Cabinet face and trim-overlap area
- Space in front for the fully open oven door
- Support platform and adjacent drawer clearance
- Old model number when replacing an installed oven
Confirm
- Exact minimum and maximum cutout dimensions
- Junction-box location and electrical requirements
- Cabinet support and ventilation instructions
- Handle projection and door-open depth
- Required filler or trim-kit compatibility
Confirm Before Ordering If
- You are replacing an older wall oven
- You are changing single to double or combination
- The cabinetry is custom or the opening is irregular
- You cannot safely access the empty cutout
- You need help comparing old and new model drawings
Nominal product size and actual cabinet cutout are not the same measurement.
04 — Cooktops
Measure the countertop cutout at more than one point.
The cooktop surface is usually wider than the opening beneath it.
Measure
- Cutout width at the front and back
- Cutout depth on the left and right
- Countertop thickness
- Clear space below the cutout
- Distance to backsplash, walls and nearby cabinets
Confirm
- Minimum and maximum cutout dimensions
- Overhang and seal area around the cutout
- Gas or electrical connection location
- Clearance to combustible surfaces
- Compatibility above a wall oven, drawer or downdraft
Confirm Before Ordering If
- You are changing gas to induction or electric
- The countertop is stone, quartz or custom material
- You are changing cooktop width
- A wall oven is installed below
- You are adding downdraft ventilation
If the opening is not square, a cooktop that fits one edge may not fit the other.
05 — Dishwashers
Measure from the finished floor to the underside of the counter.
Raised flooring and uneven openings can reduce usable height.
Measure
- Opening width at the top, middle and bottom
- Height at the left, center and right
- Depth to the back wall
- Floor height inside and outside the opening
- Door-open clearance in front
Confirm
- Water supply, drain and power access
- Handle or pocket-handle projection
- Toe-kick and leveling range
- Panel dimensions for panel-ready models
- Cabinet attachment and moisture-protection instructions
Confirm Before Ordering If
- New flooring was installed around the old unit
- The opening is tight or uneven
- You are choosing an ADA-height or compact model
- The dishwasher is integrated or panel-ready
- Plumbing or electrical access is unclear
Measure from the finished floor—not a lower subfloor hidden beneath the old dishwasher.
06 — Ventilation & Range Hoods
Match the cooking surface, mounting space and duct path.
A hood must fit the kitchen and move air correctly.
Measure
- Cooking-surface width
- Available hood width, depth and height
- Distance from cooking surface to mounting area
- Duct diameter, route and exit location
- Ceiling height for chimney or island models
Confirm
- Model-specific mounting height
- Ducted, recirculating or convertible configuration
- Blower location and compatible accessories
- Electrical connection and control requirements
- Local make-up-air and ventilation requirements
Confirm Before Ordering If
- You are adding, changing or relocating ductwork
- You are installing an island hood or downdraft
- You have a high-output professional range
- You are switching recirculating to ducted
- You are unsure which blower or duct size is required
Exact hood width, mounting height and airflow should follow the hood and cooking-appliance instructions.
07 — Room Air Conditioners
Measure the installation—then let the calculator size the room.
Use this guide for physical fit, then continue to the Ultimate AC Buying Guide and BTU Calculator.
Measure the Physical Fit
- Window opening width at the top, middle and bottom
- Clear opening height with the window fully raised
- Existing wall-sleeve width, height and depth
- Indoor and outdoor airflow clearances
- Distance to the intended electrical receptacle
Confirm the Installation
- Window, through-the-wall, portable or casement design
- Exact sleeve, chassis or opening compatibility
- Voltage, plug shape and dedicated-circuit requirements
- Support bracket, drainage and exhaust requirements
- Manufacturer-approved clearances and installation method
Prepare for the BTU Calculator
- Room length and width—or total square footage
- Ceiling height and any connected open area
- Room use, including standard or professional kitchen
- Regular number of occupants
- Sun exposure, insulation and humidity conditions
Use the Ultimate AC Buying Guide & BTU Calculator
Enter the room measurements and conditions you collected here. The calculator adjusts for ceiling height, connected space, room use, kitchen heat, regular occupants, sunlight, insulation and humidity—then builds a more relevant shopping recommendation.
- Recommended BTU range
- Volume-aware sizing
- AC-type guidance
- Filtered shopping route
The calculator can estimate cooling capacity, but it cannot confirm sleeve compatibility, window fit, voltage, plug type or manufacturer-approved installation. Likewise, a unit that fits the opening may still be too small or too large for the room.
08 — Microwaves
First identify countertop, built-in, drawer or over-the-range.
Each installation type uses different dimensions and ventilation rules.
Measure
- Available width, height and depth
- Cabinet cutout for built-in or drawer models
- Door, drawer and handle clearance
- Distance above the cooking surface for OTR models
- Surrounding cabinet and backsplash space
Confirm
- Countertop, built-in, drawer or OTR installation
- Required trim kit and compatible model
- Outlet location and electrical requirements
- Ducted or recirculating OTR ventilation
- Model-specific mounting and clearance instructions
Confirm Before Ordering If
- You are replacing a built-in microwave
- You need a trim kit or drawer model
- You are installing over a range
- The cabinetry is custom
- You are changing microwave installation type
Use only the installation method and trim kit approved for the exact model.
The appliance must reach the room before it can fit the opening.
Measure the narrowest clear width and height along the entire route. Account for handrails, trim, door hardware, tight turns and elevator openings.
Never buy from the advertised size alone.
Keep this guide open and measure with us.
Call before ordering and a Park Ave Appliance expert can review your opening, cutout, delivery route and installation questions with you. Have photos, the old model number and your measurements ready when possible.
Before you place the order
Should I measure the old appliance or the empty opening?
Measure the finished opening or cabinet cutout whenever it is safe and practical. The old appliance may not match the space precisely, and replacement models with the same advertised size can require different cutouts or clearances.
Which measurement should I use when the opening is uneven?
Measure the width, height and depth at several points. Record the smallest usable dimension because floors, walls, countertops and cabinets are not always perfectly level or square.
Are product dimensions and cutout dimensions the same?
No. Product dimensions describe the appliance itself. Cutout dimensions describe the opening it requires. Also verify door clearance, ventilation space and the approved electrical, gas, water or drainage connection zones.
Do I need to measure the delivery path?
Yes. Measure entrances, doors, hallways, turns, stairs and elevators. The narrowest part of the route may determine whether the appliance can reach its installation location.
How do I choose the right BTU after measuring the AC opening?
Continue to the Ultimate AC Buying Guide and BTU Calculator . Enter the room dimensions or area, ceiling height, connected space, room use, regular occupants, sunlight, insulation and humidity. Then confirm the selected model's exact opening, sleeve, voltage and installation requirements before ordering.
What information should I save before contacting Park Ave?
Save the opening and delivery-path measurements, photos, the old model number, fuel or voltage information and any relevant cabinet, countertop, sleeve or duct details. These make an expert review faster and more useful.
Measure the space. Confirm the specifications. Buy with confidence.
The right appliance must fit the opening, the installation, the delivery route and the way your household uses it. When anything is unclear, ask before ordering.
