Choosing the right bed and mattress is more than just a purchasing decision; it's a commitment to your comfort and well-being. Given the myriad of sizes available in the UK market, it can be difficult to know which is the right one for you. At Divan Bed Warehouse, we're dedicated to helping you find the perfect fit for your needs, ensuring restful nights for years to come.

The Different Sizes of Beds

Navigating the world of bed sizes can be a complex affair, with each size tailored to specific needs and room dimensions. These are the different bed sizes that are available in the UK, ranging from a small single to a super king size. 

Small Single

  • Dimensions: 75cm x 190cm (2'6" x 6'3")
  • Best for: Young children, guest rooms with spatial constraints, or individuals with smaller frames.
  • Tip: These beds can be an excellent choice for multi-use rooms, such as home offices that double as guest rooms.

Standard Single

  • Dimensions: 90cm x 190cm (3' x 6'3")
  • Best for: Solo sleepers, children transitioning to a bigger bed, or teenagers.
  • Tip: Two single beds in a guest room can offer flexibility for varied guest needs.

Small Double

  • Dimensions: 120cm x 190cm (4' x 6'3")
  • Best for: Solo sleepers who enjoy extra space, couples in snug rooms, or teenagers craving more room.
  • Tip: This size offers a balance between comfort and space conservation.


  • Dimensions: 135cm x 190cm (4'6" x 6'3")
  • Best for: Couples in their first homes or individuals who love ample space.
  • Tip: Being a popular size in the UK, doubles offer a vast range of bedding and design choices.

King Size

  • Dimensions: 150cm x 200cm (5' x 6'6")
  • Best for: Couples who value personal space or those frequently sharing their bed with pets.
  • Tip: The extra length is a boon for taller individuals, ensuring feet aren't hanging off the edge.

Super King Size

  • Dimensions: 180cm x 200cm (6' x 6'6")
  • Best for: Those who adore luxury, space, or families with children who love morning cuddles.
  • Tip: This size offers unparalleled space, ensuring everyone has room to stretch and turn.

Things To Consider When Choosing Your Next Bed

  • Room Dimensions: Before splurging, take precise measurements of your room. Consider space for the bed, other furniture, walking areas, and the room's overall aesthetics.
  • Personal Sleeping Habits: Your sleep pattern is crucial. If you or your partner are restless sleepers, a larger bed can be a game-changer.
  • Budgetary Constraints: While luxury is tempting, it's vital to remain within budget. Larger beds and mattresses often come with a higher price tag. Additionally, bedding for larger sizes can be more expensive.
  • Anticipating Future Needs: Life evolves. Today's solo sleeper might be part of a duo tomorrow. If you foresee sharing your bed in the near future, consider investing in a larger size now.
  • Aesthetic Balance: A bed often dictates the ambience of a bedroom. Its size can influence the room's proportion and harmony. A bed that's too large can dwarf a space, while one that's too small might seem out of place.
  • Health and Mobility: For those with health concerns or mobility challenges, the bed's height and size can significantly impact comfort and ease of access.
  • Lifestyle Needs: If you often work or read in bed, or if breakfast in bed is a weekend ritual, you might want a larger bed to accommodate trays, laptops, or books comfortably.

Accessorising Your Bed

Once you've chosen the perfect size, consider the accessories. From luxurious toppers to supportive pillows, the right accessories can elevate your sleep experience. Remember, a super king bed requires larger duvets, while a small single might benefit from specialised fitted sheets. Investing in quality bedding not only enhances comfort but also prolongs the life of your mattress.


Embarking on the journey to find the perfect bed and mattress size can seem intricate, but with the right guidance, it transforms into an exciting adventure. Your bed is more than just furniture; it's a sanctuary, a retreat, and an integral part of your daily life. Whether you're seeking a cosy single or a sprawling super king, Divan Bed Warehouse is committed to ensuring you find your dream bed. After all, sleep is sacred, and with the right bed, every night becomes a rejuvenating, restful experience.
