Comparing the Sizes

Here’s a quick comparison of the bed sizes:

  • Emperor: 215cm x 215cm (84 inches x 84 inches)
  • California King: 183cm x 213cm (72 inches x 84 inches)
  • King Size: 150cm x 200cm (60 inches x 78 inches)
  • Super King: 180cm x 200cm (71 inches x 78 inches)

Choosing the Right Bed Size

When deciding between an Emperor bed, California King, King Size, and Super King, several factors come into play. Let’s explore these considerations to help you make the best choice.

Room Size

First and foremost, evaluate the size of your bedroom. Ensure there is enough space to comfortably accommodate the bed, leaving adequate room for other furniture and allowing for ease of movement. As a general rule of thumb, you should have at least 30 inches (76 cm) of walking space around the bed.

Personal Preferences

Consider your sleeping habits and preferences. If you’re a solo sleeper, a King Size bed may be sufficient. However, if you’re part of a couple and enjoy having personal space while sleeping, a Super King or Emperor bed might be more suitable. For taller individuals, a California King could be the answer due to its extra length.


Your budget will play a significant role in the bed size you choose. Generally, larger bed sizes are more expensive, not only in terms of the bed frame and mattress but also the bedding and accessories. Keep in mind that Emperor beds often require custom-made bedding, which can be more costly.

Bed Accessories

When selecting a bed size, consider the availability of bedding and accessories. While King Size and Super King beds have plenty of options, Emperor and California King beds may have limited choices, especially in the UK and Ireland.
