Whether you’re about to embark on one of the most frustrating and joyous experience on earth (building a house from scratch) or you’re perpetually shopping for items that upgrade and turn a house into a home, it is essential to know some “standard sizes” of various architecture elements, appliances, furniture etc.
It’s true that some developers and architects pride themselves on customizing everything appearing on blueprints and house plans.
However, houses built to standard specs and fitted with standard cabinets and appliances are so much easier to replace when the time comes and standard-size replacements cost less to buy, too.
We have tried to make this article one of the most comprehensive resources on the web for listing out and explaining various standard sizes and dimensions of anything related to homes such as interior and exterior sizes, appliances, furniture etc, so let’s get started:
Kitchen Appliances and Cabinets
Standard Refrigerator Size
According to Whirlpool, when it comes to ‘fridges, there is no longer one size fits all. These four refrigerator styles are all currently considered to be standard:
- Bottom freezer models measure between 67- and 70-inches tall and are between 29½- and 32¾-inches wide.
- Top freezer units range from 61¾- and 66¼- inches tall and between 28¾- and 32¾- inches wide.
- French door ‘fridge models come in 68½- and 70-1/8-inch heights that are between 29½- to 36-inches wide.
- Side-by-side refrigerators stand between 65 7/8ths- and 71¼-inches tall and measure 32¾- to 39¾-inches wide.
- Standard refrigerators come in two depths (30- and 34-inches).
Standard kitchen oven/stove heights and widths
Fortunately, stove manufacturers have retained the same industry sizing standard for decades, so whether you install a stove top or a combination oven/stove, their sizes have been as following:
- For Electric stoves and ovens: The unit will be 30-inches wide and 36- to 47-inches height.
- For Gas stoves and ovens: The unit sizes are 36-inches wide and again 36- to 47-inches height.
- The most common height is 36-inches so it lines up with standard counter heights.
Stackable washer and dryer dimensions
Downsizing has made the stackable washer/dryer combo a popular pick for homeowners short on space, but you will have to decide if you want two front-load units that stack or an appliance that’s designed as a single unit.
- Single unit sets range from 24- to 27-inches wide and are between 70- and 75 inches tall. Commonly, depth is around 27-inches for both units, so they align when stacked.
- Freestanding stackables that occupy a single cabinet are typically 27-inches wide and at least 80-inches tall.
Standard Dishwasher Sizes
Most modern houses include a washer appliance for dishes and other kitchen utensils. Just like other home appliances, the industry has agreed to develop standard dimensions for dishwashers. Not all devices follow these dimensions but the vast majority are sized as below:
- Standard size of a dishwasher is 24 inches width x 24 inches depth x 35 inches height.
- Some other custom sizes (especially for built-in dishwashers which fit under a counter) may have sizes of between 24 – 30 inches wide, 25 inches deep and 34 inches high.
- For smaller size kitchens, you can also find compact dishwashers having dimensions of 18 or 22 inches width (depth and height are the same as the standard ones).
Kitchen sink dimensions
Contemporary kitchen sink design has made it possible for homeowners to choose between 1-, 2-, and 3-bowl models, though sizing for all three depends upon cabinet and countertop configurations, especially if that hole already exists. Homeowners can choose between over- and under-counter sinks.
- One bowl kitchen sinks can be as wide as 33-inches
- Double sinks are available in sizes up to 48-inches, with bowl size proportions typically 50/50, 60/40 or 70/30.
- Triple sinks can measure up to 60-inches wide, with unique styling determining the size of each bowl.
Kitchen cabinet dimensions
Most prefabricated kitchen cabinets are categorized as base, wall and tall units. Base cabinets lay the foundation and are usually installed first.
- Standard base cabinets range in size from 12- to 48-inches wide; 34½- to 36-inches tall and 24-inches deep.
- Wall cabinet width is the most expansive dimension, running between 9- and 48-inches. Wall cabinet heights range from 12- to 42-inches with depths of between 12- and 24-inches.
- Tall cabinets serving as pantries and housekeeping tool storage units range in width between 12- and 36-inches, while height dimensions extend from 84- to 96-inches. Standard depths are between 12- and 24-inches.

- The smallest beds on the market are cribs that measure 27- by 52-inches.

Standard seating dimensions
Today’s upholstered seating furnishings offer shoppers so many style differences, the exact same dimensions attributed to one design versus another could make the units appear to be different sizes.
Fortunately, the furniture industry has managed to keep consumers from getting too confused by producing three standard types of upholstered furniture.
- Three-seat sofas measure 35-inches deep by 84-inches wide.
- Loveseats accommodate two people and the standard size is 35-inches deep by 60-inches wide.
- Dimensions of a standard armchair are 35-inches deep by 35-inches wide.

Standard interior wall thickness
