What is a king size mattress?
If you’re considering upgrading your sleep setup, you might be wondering whether a king or California king mattress is the right choice. Here’s some information about the standard king to get you started.
Dimensions and overview
A standard king mattress, sometimes called an “Eastern king,” measures 76 inches wide by 80 inches long, giving you 6,080 square inches of sleeping space.
The width of a king mattress makes it a great choice for couples who like to spread out and have their own personal space.
Pros of a king size mattress
- The extra width means couples have plenty of personal space.
- Bedding and accessories are easy to find.
- King mattresses and accessories are often less expensive than California king mattresses and accessories.
Cons of a king size mattress
- The length may not be adequate for taller people.
- A king mattress may overwhelm a smaller bedroom.
- The extra width may make it hard to get the mattress through narrow doorways.
What is a California king size mattress?
The California king, sometimes called a “Western king,” is another popular option for those who want a large bed. Here’s an overview:
Dimensions and Overview
A California king mattress measures 72 inches wide by 84 inches long, giving you 6,048 square inches of sleeping space.
Because it’s longer than a standard king, it’s often a great choice for taller people.
Pros of a California King Size Mattress
- It’s long enough that taller people won’t have their feet dangling off the end.
- The extra length can make a large bedroom look more complete.
- It feels spacious, especially if you sleep on your back or stomach.
Cons of a California King Size Mattress
- The smaller width may not be enough for couples who like lots of personal space.
- Bedding and accessories can cost more and be harder to find.
- Its length may be too much for smaller bedrooms.
What’s the difference between a king and California king mattress?
The biggest difference is their dimensions:
- A king mattress is wider and shorter, measuring 76 inches wide and 80 inches long.
- A California king mattress is narrower and longer, measuring 72 inches wide and 84 inches long.
So, who are they for?
- A standard king is a great choice for couples and anyone under about 6’2″.
- A California king is usually a better choice for taller individuals (over 6’2″).
You’ll also find that king-sized accessories are more common and often cheaper than California king bedding. A standard king fits well in most bedrooms (at least 12ft x 10ft), while you’ll want a longer room for a California king.
The overall surface area is pretty similar between the two, but the space is distributed differently.
Factors to consider when choosing
So, you’re weighing your options between a king and a California king. Here are a few things to think about before you make your decision.
Room dimensions
First, measure your bedroom. You want to make sure the mattress fits comfortably, leaving you room to walk around and place other furniture. A bedroom of at least 12′ x 12′ is generally recommended for either size.
Visualize where the bed will sit in the room and make sure the room doesn’t feel too crowded.
Sleeper height
Taller people (over 6’2″) often prefer the extra length of a California king. If you’re on the shorter side, a standard king may give you all the room you need without sacrificing the width.
Think about how you sleep, too. If you like to stretch out fully, then the extra length of a California king may be crucial for you.
Sleeping preferences and arrangements
If you’re part of a couple and you like your personal space, you may find the king’s width more appealing. The king can also be a good choice if you’re co-sleeping with kids or pets.
Decide whether you prefer to sleep close together or like to have more individual space. This can help you determine whether the king’s width or the California king’s length is more important.
Budget and accessibility
California king mattresses and accessories can be more expensive because they’re not as popular as the standard king. King-size bedding and accessories are more common, and they’re generally more affordable.
When you’re making your decision, be sure to factor in the cost of sheets, bed frames, and other accessories.
Mattress foundation
Make sure your mattress foundation (like an adjustable base, box spring, or platform bed) is compatible with the mattress size you’re considering.
Some foundations are made just for king or California king mattresses. Using the wrong foundation could void your warranty, so double-check before you buy.
Split King and Split California King Options
You may also see the terms “split king” and “split California king.” These mattresses are exactly what they sound like: split down the middle. A split king is made up of two twin XL mattresses pushed together. Split California kings are less common, but they follow the same idea.
These mattresses are often a great choice for couples because they allow each person to customize their side of the bed. For example, one person might prefer a firm mattress, while the other likes something softer. A split mattress makes it possible to have both.
Split mattresses can also cut down on motion transfer, so you’re less likely to feel your partner tossing and turning.
To really get the most out of a split mattress, think about getting an adjustable base. These bases let each person raise or lower their side of the bed independently, which can alleviate pressure and improve sleep.
Other Standard Mattress Sizes
Mattresses come in a range of standard sizes. Here’s a quick look at some of the more common options:
- Twin: 38 inches wide x 75 inches long
- Twin XL: 38 inches wide x 80 inches long
- Full: 54 inches wide x 75 inches long
- Queen: 60 inches wide x 80 inches long
The Queen is a popular choice for individuals or couples in smaller bedrooms. A Full-size mattress works best for single sleepers or in guest rooms. Twin and Twin XL mattresses are usually used in kids’ rooms or college dorms.
And if you really want space, there’s the Alaskan King:
- Alaskan King: 108 inches wide x 108 inches long
These massive mattresses are ideal for very large bedrooms and for families who enjoy co-sleeping.
