Introduction: Your bed is one of the most important investments you will make in your life. Considering the amount of time we spend sleeping, it is essential to have a comfortable and spacious bed that promotes a good night's rest. When it comes to bed sizes, three popular options stand out: King, California King, and Super King. In this article, we will explore the differences between these bed sizes and help you choose the right one for your needs.

King Size

The King size bed, also known as the Eastern King, is the largest standard size available. It measures 182cm x 190cm (76 inches wide and 80 inches long) in Singapore. To put it into perspective, it is equivalent to two twin beds placed side by side. The King bed is most suitable for larger master bedrooms, preferably no smaller than 396cm x 396cm.


The King bed offers an ample amount of space for two sleepers. It is perfect for families who enjoy snuggling together or pet owners who like to share their bed with their furry friends. Additionally, the split king option is ideal for couples who want to be close to their partner while having the freedom to enjoy their preferred sleep positions. Another advantage of the King bed is its availability, as it is a standard size offered by almost all bed companies. This makes finding accessories like bed sheets hassle-free.


While the King bed has many benefits, there are a few drawbacks to consider. Due to its size and weight, moving or changing bed sheets can be challenging. Additionally, taller individuals (over 1.83m) may find the King bed too short, as their feet may hang off the bed.

California King Size

The California King size bed, also known as the Western King, measures 183cm x 213cm (72 inches wide and 84 inches long). If you are a tall sleeper, the California King is the better option compared to the King bed. It offers an additional four inches in length, allowing for more stretching space. However, it is narrower than the King bed, resulting in less surface area.


The extra length of the California King makes it ideal for taller individuals who need a longer bed. It is also suitable for bedrooms with a long and narrow layout, measuring around 3.6m x 4.3m. Additionally, the split option equivalent to two twin XL mattresses pushed together offers flexibility for couples with different sleep preferences.


The California King bed is bulkier and heavier than other options, making it more challenging to move. It may also come with a higher price tag, and finding accessories like fitted sheets and bed frames can be more difficult due to its less common size.

Super King Size

The Super King size bed has dimensions of 200cm x 200cm. It is slightly narrower and shorter compared to the King bed. This bed size is ideal for smaller bedrooms that require additional sleeping space.


The Super King bed consists of two standard single mattresses placed together. It offers enough room for two sleepers and children to cuddle comfortably. Like other bed sizes, it also has a split option for added convenience.


To accommodate a Super King bed, your bedroom should be at least 3.65m x 3.65m to ensure adequate space. This bed size is less common and often custom-made, making it pricier than other options. Finding suitable super king bed sheets may also be more challenging.

How to Choose Among King, California King, and Super King Size Beds

With multiple options available, choosing the right size bed can be overwhelming. Here are some factors to consider when making your decision:

Room Size

Before selecting a bed size, measure your bedroom and entryway to ensure there is enough space for installation. Ideally, there should be around 61cm of space between the sides of your bed and the walls to avoid a cramped feeling.

Personal Preferences

Consider you and your partner's sleep habits and preferences. If one of you snores or moves around a lot during sleep, a larger bed can provide extra room to minimize disturbances.

Bedding Accessories

Keep in mind that not all bedding accessories are readily available for every bed size. Custom-made options may be required, especially for rare sizes like the Super King. Ensure that you measure your mattress and check size charts before purchasing bed sheets or other bedding items.
