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:

- 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.

Standard Interior Wall Thickness
According to registered Texas architect Geoffrey Wright, interior walls are usually framed with nominal lumber, faced with gypsum board and measure an average of 4½-inches thick. Plumbing walls require additional room to accommodate pipes, thus this standard measurement is usually 6½-inches thick.
Standard Exterior Wall Thickness
Exterior walls on homes in USA are most often built to industry standards of around 6.5 inches thick. This is when using 2 x4 timber with 5/8″ drywall and outside siding.
In colder climates dimensions are now trending towards 2×6 timber so the walls are more like 8 inches. If the outside is brick add 4 more inches.
That stated, some builders insist that there is no limit to how thick an exterior wall should be.
Standard Siding Thickness
According to The American Society of Testing and Materials, vinyl siding should be at least 0.035 inches thick, which is why most of the products on today’s market are usually at least 0.04 inches thick to surpass that minimum.
