King vs California King Beds: Unraveling Their Key Differences - Inn Mattress

Deciding between a King and a California King bed can be a challenging task, particularly when you’re uncertain about their key differences. This article aims to clarify these differences in terms of dimensions, ideal users, room size considerations, price points, and more, assisting you in making an informed decision that aligns with your specific needs and preferences.

Understanding the Basic Differences

When it comes to choosing between a King and a California King bed, understanding their fundamental differences is essential. A King bed is wider but shorter, offering ample space for couples or families who prefer extra width. Conversely, a California King bed is narrower but longer, making it an ideal choice for taller individuals or those with a narrow and long bedroom layout.

The Key Differences Between King and California King Beds

What Is a King-Size Bed?

A king-size bed typically measures 76 inches wide by 80 inches long. This makes it wider but slightly shorter than a California king-size bed. Due to its extra width, a king-size mattress is perfect for couples who need more space when sleeping.

Key features of king-sized beds include:

  • They fit well in large bedrooms.
  • They can accommodate couples who like their own space while sleeping.
  • Many bedding options and accessories available.


  • Extra room for couples
  • Easy access for people with mobility issues due to smaller length
  • Available in many styles


  • Not an ideal option if you’re taller – limited length

What Is a California King Bed?

A California king bed, also known as Cali-King or Western-King Size mattress, measures approximately 72 inches wide and about 84 inches long. It offers plenty of room for taller individuals since it’s four inches longer than traditional Eastern (Standard) Kingsize mattresses.

Notable characteristics of this type of mattress include:

  • Longer but narrower compared to King Size
  • Perfectly suits master bedrooms with standard square footage walls and floors
  • Provides ample legroom


  • More comfortable sleep experience for tall people
  • Longer length allows quick conversion from infant co-sleep surface
  • Can comfortably fit families including parents and kids


  • Narrower so less personal space per person compared to Standard King Width

King vs. California King Dimensions

The dimensions of the beds are a key difference. A standard King bed measures 76 inches wide by 80 inches long, providing a large square surface area that’s perfect for couples who like their personal space when sleeping. On the contrary, a California King bed measures 72 inches wide by 84 inches long. While it’s 4 inches narrower than the King, it’s 4 inches longer, catering to individuals who are taller and need that extra legroom.

Ideal Users for Each Bed Size

The choice between a King and a California King bed often boils down to the user’s specific needs. Taller individuals or those who have pets or children joining them in bed might prefer the extra length of a California King. Conversely, couples or families who value extra width might find a King bed more to their liking. The layout of the bedroom can also influence this decision.

Room Size Considerations

The size and layout of your room play a significant role in choosing between a King and a California King bed. A California King bed, being longer, fits well in rooms that are longer rather than wider. On the other hand, a King bed, with its extra width, is more suitable for rooms that are square or wider.

Price Considerations

While the price points of King and California King beds are usually around the same, the cost of accessories like bed sheets, comforters, and bed frames can vary. Accessories for a California King bed might be slightly more expensive and harder to find due to its less common size.

BedBase and Foundation

Choosing the correct bed base and foundation is crucial for both mattress sizes. Both King and California King beds work well with adjustable bases, foundations, platform beds, and more. However, ensure the base or foundation you choose matches the size of your chosen mattress.

How Do You Know Which Size Is Right for You?

When it comes to choosing between a king-size bed and California king-size bed, there are some factors to consider, such as:

  1. Bedroom Space

Consider the size of your bedroom when deciding on a bed size. A kingsize is typically wider than a Cali-King but shorter in length. Meanwhile, California King beds require extra space for comfortable placement.

  1. Sleeping Habits

Think about how you sleep with your partner or if you frequently share the bed with children, pets or even pillows which add up more room requirements within the sleeping area.

Do you tend to stretch out while sleeping or do you prefer being packed tight? Based on this preference decide which width/length will give each sleeper sufficient amount of personal space.

  1. Height Requirements

If either or both partners are tall (6’ feet+) then opt for California King beds due to their longer length that provides plenty of legroom necessary for better comfort levels during sleep.

Final Thoughts

Choosing between a King and a California King bed depends on various factors, including your height, room size, and personal preference. By understanding their key differences, you can make an informed decision that ensures a good night’s sleep.

Which one is bigger – King or California King Bed?

Technically, a standard King size bed is wider than a California King. However, due to its lengthier design and unique shape, the latter can accommodate taller individuals better giving them more legroom.

Do I need special bedding for a California King Bed vs A Regular King Bed?

Yes, due to the difference in dimensions of the two beds, you will require special bedding for each respective size. Therefore, make sure to choose appropriate sets designed specifically for your particular mattress so that it fits comfortably over it without any hassle or discomfort during use.

What’s The Difference Between Eastern and Western Kingsize Mattress Sizes?

The Standard/Eastern Kingsize Bed is approximately four inches larger in width compared to its Western Californian counterpart – making it ideal for those who need more personal space without sacrificing too much individual legroom in small-sized bedrooms.
While both sizes provide enough room options among available supportive bedding products catered by brands like InnMattress.

Can I Use the Same Sheets For Both Beds?

The answer is no; sheets designed specifically for one size may not fit another one properly, leading to uncomfortable slips or bunches during sleep time – leaving your comfort level compromised.
It’s best practice always to buy these accessories from trusted mattress retailers like InnMattress where product comparisons come easy in price range, thread count quality etcetera.
