Common Floor Plans for Studio Apartments Not all studios are the same. Half walls or built-in bookcases may be used in certain studio floor designs to help divide the rooms. Studio apartments may often feature high ceilings, giving the place a more spacious sense. If you're looking to move into a new apartment, then it's important to understand the differences between a one-bedroom and two-bedroom apartment. Size is only one factor that determines how much rent you should be paying. Other factors include availability of amenities, location, etc. But first, you need to know what kind of apartment you're looking at. One-bedroom apartments usually measure around 500 square feet or more. They typically have one living room and one bedroom. Two-bedroom apartments are usually larger, with 1,000 square feet or more. There are usually two separate bedrooms and one large common area, such as a living room or dining room. Most two-bedroom apartments will also have a full bathroom on each level. There are many different types of one-bedroom apartments, too. Some include a kitchen, some do not. Some have small balconies, others do not. But they all share a few common features: one large open space and one private room.
