What Is An Eastern King-Size Bed?

The Eastern king-size mattress, otherwise known as just a regular king mattress, is 76 inches wide and 80 inches long. Improving upon many of the other standard mattress sizes, such as twin, full, and queen, Eastern king-size beds offer a spacious abode for an average family of four to co-sleep.

Why Is It Named the "Eastern" King Bed?

The name "Eastern" king bed was devised to separate it from the other popular option at the time - the California king bed, aka the "Western" king bed.

As World War II was left behind in the rearview mirror, houses in the US were becoming larger and larger. To satiate the needs of these huge spaces, big bed sizes were needed. Subsequently, California king mattresses started gaining popularity among the masses, especially on the west coast.

Capturing the 'big bed' trend in the mattress industry and offering an alternative to the California kings, the Eastern king beds were introduced. As they went against the narrower build of Cal king beds to instead offer more width, Eastern king beds were adopted more and more across the industry.

Later on, as they became a standard mattress size in the country, the "Eastern" was removed from the name for simplicity's sake.

What Is the "Western" King Bed?

While there are no "Northern" or "Southern" king-size beds (as far as we know), there are "Western" king-size beds. You might be familiar with them by their other name - California King Mattress. Yep, the Western king-size mattress is the California king-size mattress, which is 72 inches wide and 84 inches long. We'll discuss more about them in the next section.

How Do Eastern King Mattresses Fare Against Other Standard Mattress Sizes?

Other standard mattress sizes include twin, twin XL, full, and queen. All of them are smaller mattress sizes compared to the Eastern king mattress size.

The twin-size bed measures 38 inches wide and 75 inches long, making it best suited for a thin single sleeper or a small child.

The twin XL bed measures 38 inches wide and 80 inches long, 5 inches longer than a standard twin bed, making it ideal for taller single sleepers or growing teenagers.

The full-size bed measures 54 inches wide and 75 inches long. It offers enough space for an average single sleeper to stretch out comfortably.

The queen bed size measures 60 inches wide and 80 inches long. Aside from being more than spacious enough for single sleepers, queen beds are also a great budget option for couples.

All of the above sizes are smaller than the traditional king mattress (76-inch by 80-inch). Though king beds provide more space, they are also expensive to maintain. For instance, to comfortably accommodate a king-size mattress, something like a master bedroom is required. Furthermore, king-size mattresses require a bed frame/bedding accessories with almost the same dimensions, which are more expensive.

Should You Choose an Eastern King Mattress?

Here are reasons why you should and shouldn't choose an Eastern king mattress -

  • Reasons to Choose an Eastern King Mattress

Ample Sleeping Space: Eastern king mattresses offer a generous sleeping area with 76 inches of width. They are a great pick for couples who want to move around during the night without bumping into each other often.

Suits Taller Individuals: The 80 inches of length offered by an Eastern king mattress provides added legroom for taller individuals above 6 feet.

Spaciousness: If you have a large bedroom with ample floor space, an Eastern king mattress can create a luxurious sleeping environment that fits the aesthetic.

Versatility for Co-Sleeping: An Eastern king mattress can usually accommodate parents with children/pets who want to share the bed.

  • Reasons Not to Choose an Eastern King Mattress

Limited Bedroom Space: If your bedroom is on the smaller side, an Eastern king mattress may dominate the space, leaving little room for walking/furniture placement.

Bedding Accessories: Finding suitable bedding accessories for an Eastern king mattress is usually expensive. Accessories like box springs and bed frames need to match the size of the Eastern king bed, thereby increasing in cost.

Cost:  Eastern king mattresses can be costly, mainly due to their larger dimensions, which require more materials to make. The cost of sustaining an Eastern king bed could be higher as well.

Solo Sleepers: For single sleepers who don't necessarily require a larger bed, an Eastern king may be unnecessary. It can take up more room than needed without providing many benefits in return.

An Important Factor to Consider Before Buying an Eastern King-Size Bed

different mattress types

Choosing the right mattress goes beyond just glossing over the various mattress size difference offered by retailers. A primary factor to consider is the mattress type you choose. Latex, memory foam, innerspring, and hybrid mattresses all offer something unique for different sleeper types and sleeping positions.

For instance, a side sleeper may be better suited to the cushioning offered by latex or memory foam mattresses. Back and stomach sleepers, however, may require the more firm support offered by innerspring and hybrid mattresses.
