What Size Is a King Size Bed?

The dimensions of a king-size mattress are 183 centimetres wide by 203 centimetres long. While it’s the same length as a queen mattress, it’s wider by 20 cm, providing enough space for a couple with a child or a pet.

Who Is This Size Best For?

Going big is always a good idea if it fits your budget and bedroom space. Even while a smaller mattress option is sufficient when you have the entire bed to yourself, most people agree that upgrading to a comfortable mattress king bed is entirely worth it if you prefer to sprawl out.

A larger bed can significantly enhance your sleep if you share a bed. You won’t be as likely to notice the other person moving around if there is plenty of space. Your back, neck, and shoulders should feel better in the morning as you’ll be less tense and less likely to experience muscle and joint pain. That’s especially true if your children or pets join as well.

A king-size mattress gives each one the same room as a twin mattress. That means more elbow space, which is especially important if one or both of you are tummy sleepers.

How Do I Choose a King Size Bed?

Which mattress is best for you depends on your sleeping position, body type, and personal preferences for the feel and materials. You should also evaluate your sleeping habits, including whether you tend to get overheated while you sleep, experience back pain, or frequently wake up as your partner moves.

Types of Mattresses

Although innerspring and memory foam beds are the most frequent, other types are becoming more widely available to give customers more options. You can still find a range of firmness levels and price points within each mattress type. Here’s how to select your mattress type.

Memory foam

The finest pressure relief comes from memory foam mattresses, which adjust to your body and relieve pressure spots. Users describe lying on foam beds as being in a cradle. Because they support healthy spine alignment by reducing tension on your shoulders and hips, these mattresses are excellent for side sleepers or anyone who suffers from back pain. They also help with motion isolation, making it less likely to feel your sleeping partner move.


Although memory foam and latex mattresses feel somewhat similar, latex is firmer, feels more sturdy, and sinks less. Since natural latex comes from rubber plants found in organic mattresses, it is an excellent option for consumers who care about the environment.


These mattresses have extra bounce since they employ steel coils, which makes them firmer. Many buyers are more comfortable with innerspring mattresses than boxed mattresses which have recently gained popularity. They’re better suited to back and stomach sleepers since a more unbending surface helps preserve the spine in proper alignment.


Hybrid mattresses combine coils with memory foam or latex to avoid forcing you to choose just one material. Recently, especially for internet mattress brands, these have grown in popularity. Coils often offer support at the bottom, while foam provides pressure relief at the top. When you lie down, many hybrid mattresses, especially those made by bed-in-a-box companies, feel like foam beds. Just remember they’ll cost more and need more effort to set up than all-foam alternatives.

Mattress Firmness Levels

The most typical mattress descriptions are soft, medium, medium-firm, or firm. The most common bed types are medium to medium-firm ones since they can accommodate various needs. It’s crucial to consider your sleeping posture and body type while choosing your firmness level.

Sleeping Posture

Side Sleepers

The side sleeping position is the most popular posture medical professionals often advise to prevent back problems. Soft to medium firmness levels are ideal for side sleepers because they support proper spinal alignment. You can wind up placing too much strain on your hips and shoulders on an overly stiff king-size mattress.

Stomach Sleepers

Anyone who likes to sleep on their stomach should choose a firmer mattress because you don’t want your pressure points to sink too deeply in this position.

Back Sleepers

In this instance, a medium firmness is preferable. In this position, if your mattress is either too soft or too hard, you run the risk of not having appropriate alignment.

Combination Sleepers

If you alternate between different positions while you sleep, choose a medium-firm mattress king bed to support your body in distinct circumstances.

Type of Body

Weightier People

A firmer mattress is preferable for weightier people because heavier bodies put more strain on the mattress. Back pain might result from the bed sinking in too far, compromising the spine alignment. Some of the best mattress manufacturers even provide models designed exclusively for customers weighing over 120 kilos.


Because they aren’t exerting as much weight on the bed, softer king-size mattresses best suit people with smaller body frames. If the bed’s too hard, it won’t reduce joint pressure.

When choosing your ideal firmness level, think about both your weight and your sleeping posture. If you sleep on a stomach and aren’t very heavy, you might choose a medium hardness as a happy medium between soft and firm.

Other Sleep Concerns

Beyond selecting your mattress type and firmness, consider your unique needs. Here are common concerns and what to seek:

Hot Sleepers

Choose a cooling mattress to stay comfy if you get too warm at night. While it won’t fix all issues, it helps with overheating. Some options are:

  • Built-in cooling tech: Copper, gel, phase-change materials.
  • Cool-to-the-touch covers: Instant cooling effect.
  • Breathable design: Innersprings and certain hybrids.
  • Electric cooling: Water or air-based, more upkeep.

Also, it’s crucial to pick the right bedding to prevent overheating. Choose sheets made of natural fabrics with moisture-wicking properties.

Back Pain

For back pain, choose a medium-firm mattress with foam for relief and support. Back specialists agree the right mattress can aid in improving pain, stiffness, and sleep quality by 50-60%.
