Which Bed Size Is the Biggest? Understanding UK Bed Sizes

When it comes to choosing the perfect bed, size matters – especially if you're seeking comfort, luxury, and a good night's sleep. In the UK, bed sizes can range from the modest 3ft single to the grandeur of the 6ft super king size. Understanding these sizes is crucial when selecting the right bed for your needs, whether you're furnishing a compact guest room or a lavish master bedroom. Let's break down the UK bed sizes, including the nuances between mattress size and actual bed dimensions.

1. 3ft Single

The 3ft single bed is an ideal choice for children's rooms, small bedrooms, or multi-purpose rooms. Measuring 3 feet (90 cm) in width and 6 feet 3 inches (190 cm) in length, it offers ample space for one person to sleep comfortably. It's also a popular option for guest rooms, as it doesn't occupy too much space while still providing a comfortable sleeping area.

Space and Room Consideration:

  • Ideal for smaller or narrower rooms.
  • Perfect for children or solo sleepers.
  • Leaves more room for other furniture and space to move around.

2. 4ft Small Double

Slightly larger than the single, the 4ft small double, also known as a three-quarter bed, measures 4 feet (120 cm) in width and 6 feet 3 inches (190 cm) in length. It's a great middle ground between a single and a standard double bed.

Ideal Usage:

  • Suitable for solo sleepers who prefer more space.
  • A good option for smaller master bedrooms or guest rooms.
  • Can accommodate two people, but with limited personal space.

3. 4ft6 Double

The 4ft6 double is one of the most common bed sizes in the UK. It measures 4 feet 6 inches (135 cm) in width and 6 feet 3 inches (190 cm) in length. This size is versatile, fitting well in most standard-sized bedrooms and providing ample space for two adults.

Versatility and Comfort:

  • Ideal for couples in a standard-sized bedroom.
  • Offers a comfortable amount of space for two people.
  • Also a luxurious option for a solo sleeper.

4. 5ft King Size

The 5ft king size bed is a step up in luxury and space. It measures 5 feet (150 cm) in width and 6 feet 6 inches (200 cm) in length, giving extra room for individuals or couples who prefer more space while sleeping.

Spacious Luxury:

  • Offers additional width and length compared to a double bed, making it more comfortable for two people.
  • Ideal for couples who value personal space while sleeping.
  • A popular choice for larger bedrooms to maintain a balanced look.

5. 6ft Super King Size

The largest standard UK bed size is the 6ft super king size. Measuring an impressive 6 feet (180 cm) in width and 6 feet 6 inches (200 cm) in length, this size offers the ultimate sleeping experience in terms of space and comfort.

Ultimate Comfort and Space:

  • The best choice for couples who want maximum personal sleeping space.
  • Ideal for large master bedrooms, providing a luxurious look and feel.
  • Ample space to accommodate children joining their parents in bed or for those who simply enjoy sprawling out.

Bed Base vs. Mattress Size Consideration

It’s important to note that while these sizes refer to the mattress dimensions, the actual bed frame or base can be larger, depending on its design and type. For example, a 5ft king size bed will require a 5ft king size mattress, but the bed frame itself may extend further, especially if it features a headboard, footboard, or an elaborate frame design.

Factors Influencing Bed Base Size:

  • Headboards and Footboards: Some designs incorporate extended headboards or footboards, adding to the overall length and width of the bed.
  • Frame Design: The style of the bed frame, such as those with built-in side tables or extra padding, can also increase the dimensions.
  • Storage Features: Beds with built-in drawers or an ottoman-style lift-up base will have larger dimensions to accommodate these features.

Choosing the Right Bed Size: Things to Consider

When selecting the bed size, consider the following aspects to ensure you make the right choice for your space and comfort needs:

Room Size:

  • Measure your room to ensure the bed fits comfortably, leaving enough space for movement and additional furniture.

Sleeping Habits:

  • Consider your sleeping habits, such as if you move around a lot or if you sleep with a partner. Opt for a larger size for greater comfort if you tend to move around.

Future Needs:

  • Think about the longevity of your choice. For instance, a king size may be a better investment if you plan on sharing your bed in the future.

Aesthetic Balance:

  • Consider the bed's proportion in relation to your room size to maintain aesthetic balance and functionality.


Choosing the right bed size is a balance of practicality, comfort, and room aesthetics. From the compact 3ft single to the expansive 6ft super king size, there's a bed size to suit every need and room size.
