There are several different types of apartments under one real estate property and their sizes need to be measured. The proper size of an apartment can be defined in meters or in square feet. This measuring unit also differs from nation to nation and from continent to continent. It’s different in USA and in Europe.

In the US the size of the apartment it’s called the “living space”. This particular “living space” however does exclude garage as well as other non living spaces. In Europe it is measured in square meters and this is a place where the measurement includes the complete area of the walls that surrounds the particular house. Unlike US in Europe the garage space as well every non-living space is included.
A studio apartment usually comprises of a single bedroom and is devoid of a living room while a single bedroom apartment has just one dining and living room that is separate from the bedroom.
