When it comes to bedding, not everyone wants or needs a king-size option. Fortunately, there are a variety of synonyms available to describe sizes that are smaller than king-size. Standard size is a popular option that is often used interchangeably with queen-size. Twin and twin XL are both smaller than queen-size and are ideal for single sleepers or children. Full-size, also known as double, is larger than a twin but smaller than a queen. Finally, there is the California king, which is longer and narrower than a traditional king-size bed. No matter the size, there are plenty of options available for a comfortable night's sleep.
