King vs Super King: A Definitive Guide to Luxury Dimensions
Choosing between king vs super king bed sizes is a balancing act between your room’s proportions and your appetite for luxurious comfort. In this guide, our experts will walk you through the physical and sensory nuances of the most coveted bed sizes, helping you define the boundaries of your bed.
King-sized beds have regal proportions
The British King-size bed, measuring 150cm by 200cm, is the quintessential choice for an expansive primary bedroom. But what many people don’t know is that the difference between a super-king and a king is width alone. Both bed sizes are 200cm long as standard. So, when you’re evaluating king-size vs super king, a king-sized bed is often the preferred choice when you’re positioning the headboard on the longer walls of a bedroom. This allows you to enjoy the indulgent width without compromising on space around the margins.
At five feet wide, the King still offers a significant upgrade from the standard double bed, providing each sleeper with 75cm of lateral space. This is often sufficient for couples who enjoy a sense of closeness, as some couples find that moving from a double to a super-king leaves them feeling isolated..
Expertly scaled, a King bed allows a room of 12 to 14 square metres to retain its breathing room, ensuring the furniture feels considered, rather than a crowded necessity. For a deeper exploration of how these dimensions sit within your home, you may find our guide on choosing the right size bed an invaluable resource.
The grand horizon of super king vs king
To decide between a super king vs king is to move into expansive territory. At 180cm wide, this 6ft marvel represents the pinnacle of bedroom luxury, offering you swathes of luxurious comfort. The size difference between king and super king is just over 30cm. At first, you might think that an extra 15cm each isn’t much, but when you lie on a super king bed, you’ll soon learn the truth.
If you’re a light sleeper, the extra few centimetres are crucial to ensuring that you remain undisturbed by your partner’s nighttime stirrings.
The super king is also often the definitive choice if you share your mornings with children or pets, or simply wish to wake in a cool, untouched expanse of silk.
However, the grandeur of a super king bed requires a grand stage — ideally a space of at least 16 square metres. This is the minimum floor space that we recommend to balance your bedroom’s proportions, living space, and furniture.
To help you envision the presence of each frame within your sanctuary, our experts have outlined the architectural specifications for our signature UK sizes:
| Dimension | King size (UK) | Super king size (UK) |

| Length | 200cm (6ft 6") | 200cm (6ft 6") |
| Sleeping surface | 3.0m² | 3.6 m² |
| Recommended floor space | 12-14m² | 16 m²+ |
Navigating the practical difference between king and super king
Beyond the physical size difference between king and super king, you need to think about how to get the bed from your front door to your bedroom. A super king bed is a substantial entity; its journey through narrow stairwells or around heritage bannisters requires a delicate touch. Our experts often recommend measuring the turn of your staircase as carefully as the floor space of the bedroom itself. At Feather & Black, our king-sized bed frames are intelligently designed to be as compact as possible and simple to assemble. This allows our delivery teams to navigate even the most modest homes with ease.
“Pair your super king bed with wider, more substantial bedside tables — ideally between 60cm and 70cm — to complement the 6ft frame. Equal space on either side of the bed is important, as we discuss in our guide to Feng Shui for the bedroom; this symmetry is vital for inviting a sense of partnership and equilibrium into your sleep.”
