How Wide is a King Size Mattress

Ensuring you have the right mattress can make all the difference between a restless night and waking up refreshed. For many, the king size mattress provides the perfect blend of space and comfort. But what are the exact dimensions of such a mattress and how do you determine the right one for you? Dive into this detailed guide to find out.

How wide is a king size mattress?

A standard UK king size mattress measures 150cm in width, equivalent to approximately 59 inches. This width is designed to provide ample space for individuals or couples to sleep comfortably without feeling cramped. It’s a popular choice among adults who seek additional room, especially when compared to the more confined space of a double mattress.

The extra width not only offers added comfort for sleepers but also allows for activities like reading, lounging, or watching television in bed. When considering purchasing a king size mattress, it’s important to take into account factors such as the layout of your bedroom, the presence of any other furniture and the accessibility of pathways around the bed. Furthermore, considering bed linens and protectors that specifically fit this size will ensure a snug and well-maintained sleeping surface.

Before committing to a king-size mattress, make sure you’ve measured your bedroom. Ensure it comfortably accommodates the spacious 150cm width, giving you restful nights.

Decoding the king size mattress: Your ultimate checklist

Picking out the perfect king-size mattress is about more than just size. Here’s a more in-depth checklist:

Who the bed or mattress is for

  • If it’s for children or guests, you might reconsider the need for a king size. But for a couple who value space or a single sleeper who loves luxury, it’s an excellent choice.

How tall you are

  • Those on the taller side might appreciate the 200cm length, ensuring feet don’t dangle off the end!

Your available space

  • A spacious room can comfortably fit a king size mattress, but remember to account for other furniture and walking space.

Whether you will be sharing the bed

  • Sharing the bed can influence the type of mattress you choose, especially when considering movement transfer and space requirements.

What is your body type and how wide are you

  • Your body type, whether you have a broader build or a slender physique, can influence the kind of support and space you need. A wider individual might appreciate the spaciousness of a king size.

What feel you like

  • With luxurious fibres like horsehair, cashmere, wool, flax and coir, you can experience a unique comfort that caters to your preference.

Spring tension you require

  • This often correlates with weight. Heavier individuals might find a firmer spring tension more comfortable and supportive.

Medical ailments

  • Conditions like back pain or arthritis might necessitate a mattress with specific support or pressure relief features.

Diving deeper: Are all king size mattresses crafted equal?

No, not all king size mattresses are created equal in terms of their dimensions. While the typical dimensions for a UK king size mattress are set at 150cm in width and 200cm in length, variations might occur, sometimes by up to 2cm.

This discrepancy is often attributed to diverse factors such as the specific materials used, subtle differences in manufacturing processes, or how the mattress has been stored. Thus, when you’re in the market to buy a king size mattress, it’s crucial to check the exact measurements provided by the manufacturer or retailer to ensure you’re getting the size you expect.

Your comprehensive guide to mattress sizes: Beyond the king size

Choosing the right mattress size is pivotal for a good night’s sleep, impacting not only your comfort but also the aesthetic and functionality of your bedroom.

Single mattresses (90cm x 190cm or 35″ x 75″)

  • A single mattress is most commonly used for children transitioning from toddler beds or for adults with limited bedroom space. It’s also a common choice for guest rooms, ensuring that your visitors have a comfortable sleep.

Small double mattresses (120cm x 190cm or 47″ x 75″)

  • This size, sometimes referred to as a three-quarter mattress, is an excellent middle-ground for teenagers who have outgrown a single mattress or for solo adult sleepers who prefer a bit more room. It’s also a good fit for guest rooms or studio apartments where space may be at a premium.

Double mattresses (135cm x 190cm or 53″ x 75″)

  • Double mattresses are one of the most popular choices for adults, particularly young couples starting out. They provide ample space for an individual, but can also accommodate two adults, although with less personal space than larger sizes.

King size mattresses (150cm x 200cm or 59″ x 79″)

  • Offering a noticeable upgrade in space from a double, the king mattress is often chosen by couples who prefer more personal room or by individuals who just enjoy sprawling out. Their additional length also makes them a preferred choice for taller individuals.

Super king mattresses (180cm x 200cm or 71″ x 79″)

  • The super king is the epitome of space and luxury. This size is ideal for couples who want the maximum amount of personal sleeping space, or for families where children or pets might join in bed occasionally.

Emperor and Large emperor mattresses

  • These mattresses are for those who want an unparalleled sense of luxury and spaciousness. Their dimensions can vary, but they’re larger than super king mattresses. They’re not as commonly found, so always check the specific measurements when considering this option.

Remember, beyond size, the material and firmness of a mattress are crucial for comfort. Consider all these factors in conjunction to find the perfect mattress for your needs.

The perfect king sized mattress: Tailored to your unique needs

Choosing the right mattress is a highly personal decision that impacts your quality of sleep. When considering a king size mattress, here are in-depth factors to bear in mind:

Sleeping Partner(s)

  • If you’re sharing the mattress, communication is key. It’s essential to discuss individual preferences with your partner. For instance, does one of you prefer a firmer feel, while the other leans towards softness? You might also want to consider mattresses that have excellent motion separation, ensuring that one person’s movements don’t disturb the other.

Your Size, Weight and Sleeping Position

  • These personal factors significantly influence your mattress choice. For side sleepers, a mattress with a bit more softness can accommodate the natural curvature of the body, especially around the shoulders and hips. Conversely, back or stomach sleepers may gravitate towards medium to firm mattresses to ensure proper spinal alignment. Your weight plays a pivotal role in selecting the right spring tension. A mattress should be supportive and offer even weight distribution, aligning with your body’s unique contours.

Budget

  • While kingsize mattresses provide a luxurious sleeping experience, they come in various price ranges. It’s essential to balance cost with features like durability, warranty and quality of materials used. Remember, investing in a high-quality mattress can mean fewer replacements in the long run, ultimately saving money.

Bedroom Size

  • Beyond the mattress itself, think about how it will fit within your bedroom. A king size mattress should be positioned so there’s enough space to move around comfortably. A general guideline is to leave at least 24 inches of space on each side of the bed, ensuring you have room for bedside tables and ensuring that pathways remain unobstructed.

Summary: Finding your perfect king size mattress

The journey through the realm of king size mattresses can seem overwhelming, given the plethora of options available. However, with a foundational understanding of the standard width of 150cm, coupled with the myriad of personal factors to consider, you’re on the path to pinpointing your dream mattress. Here’s to making an informed choice that promises countless nights of rejuvenating sleep on your chosen king size mattress!
