What Size Mattress Do You Need for a King Size Bed?

A king size bed is designed to provide more room for you and your partner to sleep comfortably. The larger size of the mattress is meant to accommodate all sizes of people, from those who are tall and lanky to those who are short and stocky.

The king size bed is the perfect choice for those who want to get a luxurious and comfortable sleep. However, it can be difficult to find the best king size hybrid mattress that will match the size of your king size bed perfectly. But, you need not to worry, read on for an acute guide on what size and how to get the perfect mattress for your king size bed.

What Is the Difference Between King and Cal King?

The main difference between king and californian king mattresses is that the cal king has an extra 2 inches of length on each side, so if you have an oversized cal king bed, this might be something to consider when purchasing your new mattress.

The other difference is that the king mattress is wider than the cal king by 3 inches on each side. In general, there are no differences in comfort or support between these two types of beds, but there are some differences in price depending on how much extra material is used on each side of the bedding.

The most important thing when buying a new mattress is making sure that it fits properly into your existing frame or box spring so that it does not come loose over time or jump around while someone sleeps.

Mattress Size for a King Size Bed

A king size mattress is a mattress that is approximately 80 inches wide and 76 inches long. This is larger than the standard king size bed which measures 76" x 80".

Take a look at the different sizes of mattresses that are available:

  • Twin XL: 39" x 80" (54" w/ footboard)
  • Full: 54" x 75" (75" w/ footboard)
  • Queen: 60" x 80" (80" w/ footboard)
  • King: 76" x 80" (80" w/ footboard)
  • California King: 72" x 84" (84" w/ footboard)

However, the exact dimensions for a king size mattress vary by manufacturer and model, but the general size specifications are the 80 by 76 inches.

Features to Look for in King Size Mattresses

A king size mattress is large enough for two people to sleep comfortably. It can be a great alternative to separate beds, or even just an option if you are buying a new bed and want to replace your current one.

The following are some features that you should look for in a king size mattress:

  • Look for a mattress that has been manufactured by a well-known company. This will ensure that you are getting a quality product and can be sure that it will last for years to come.
  • Look for an inner coil spring system in the mattress. These springs provide added support and comfort when sleeping on them.
  • Look for gel infused memory foam in your mattress. This material works to keep you cool while sleeping so that you don't get too hot while you're trying to relax at night.
  • Make sure that your new king size mattress includes a warranty from the manufacturer, just in case something goes wrong with it over time.


The right mattress size can make a huge difference in your sleep quality and comfort, so it's important to figure out which option will work best for you. Picking the right mattress size is critical, so it's worth taking the time to do your research and find one that meets your personal needs.
