|Room Size||Small rooms and guest bedrooms||Master bedrooms|
Both of these mattress sizes offer unique sleeping benefits so it’s best to take a step back and assess your unique sleeping needs. Key considerations to make include your sleeping position, whether you share the bed, your budget, and importantly whether you have enough space in your bedroom.
To get a good night’s sleep, your mattress plays a key role. Other than the type of mattress you choose, the size of your mattress can make a considerable difference to the quality of your rest. A full size bed, also referred to as a double bed, is quite versatile as it’s small and compact. Whereas a king size bed usually requires a master bedroom.
A bed that’s too big for your bedroom isn’t just a decor nightmare, it can also impact your sleep. So before you indulge and buy a huge bed such as a king size, take a look around your room and know exactly how much space you have to work with.
As a general rule of thumb, to fit a king mattress in your room, the surface area should be at least 12 x 12 feet. If your room is smaller than this, you may need to consider downsizing to a full or even queen mattress. When designing a bedroom, some people make the bed a focal point of the design. This is fine, however, it’s important to factor in the other pieces of furniture that might need to fit in the room. Not to mention, other decorative accents such as rugs, pillows, artwork, and mirrors - all these elements take up space so it’s important to get your mattress size right.
Full size beds are best suited for small bedrooms, teen bedrooms, dorm rooms, guest bedrooms, and studio apartments. King beds are usually reserved for the master bedroom or open plan living spaces that are not restricted by walls.
