A king size bed measures 150 x 200cm and gives two adults around 75cm of personal space each -- noticeably more than a double, and the reason most couples who make the upgrade say they wished they had done it sooner. At Land of Beds, we've been helping people across the UK get this right for over 50 years. Whether you want a king ottoman that handles the storage challenge in a main bedroom, an upholstered frame that becomes the room's centrepiece, a wooden bedstead built for the long term, or an adjustable base for different sleep or health needs, our range of over 500 king size beds covers every requirement. Free mainland UK delivery, a Price Promise Guarantee, and honest advice from people who know this category properly come as standard.

Most people buying a king size bed have already decided on the size. The room takes it, they want more space, and they are ready to invest properly. What they are working through is which type suits the room, whether storage needs to be built in, and which construction gives the best support for the mattress over time. At Land of Beds, we've been helping couples work through exactly this for over 50 years, with honest advice and no pressure to buy.
| Factor | Why It Matters | What to Check |
|---|---|---|
| Type and storage | A king size bed is almost always a couple's main bed, used every night for years. The type determines how storage works, how the base supports the mattress, and how the bed looks. Getting the storage wrong -- particularly drawer clearance -- is the most common specific frustration at this size. | Whether storage is needed, room clearance for drawer types, whether design or practicality is the priority |
| Room fit | A king needs approximately 3.5m x 3.5m with 60cm clearance on each side and at the foot. In rooms too small, a king makes the space harder to live in every day. The bed has to work in the room, not just fit inside it. | Exact room dimensions, clearance on each accessible side, whether the furniture layout functions properly around a king |
| Base quality and mattress compatibility | A king is a significant purchase. A poor base shortens a good mattress's life and undermines the investment from day one. Slat spacing, base construction, and gas-lift specifications all affect long-term mattress performance. | Frame construction, slat spacing, gas-lift specifications for ottoman options, base type relative to mattress choice |
A standard UK king size bed measures 150 x 200cm (5ft x 6ft 6in). This is the most popular size for main bedrooms where two people share regularly.
| Dimension | Measurement | Notes |
|---|---|---|
| Width | 150cm (5ft) | Gives two adults approximately 75cm each -- more personal space than a double (67cm each), though less than a full single bed each |
| Length | 200cm (6ft 6in) | 10cm longer than double and single sizes. Suits sleepers up to 6ft 3in comfortably. |
| Space per person | Approximately 75cm | More than a double (67cm each); the difference most couples who upgrade say they notice immediately |
| Minimum room width | Approximately 3.5m | With 60cm clearance on each accessible side and at the foot |
King size is 15cm wider and 10cm longer than a standard double. For most couples, that extra width is the meaningful change -- 75cm per person versus 67cm affects how much each partner feels the other move during the night.

Our recommendation
Choose a king if: your room is 3.5m wide or more, two adults share regularly, and you are upgrading from a double. For most couples in a standard UK main bedroom, king is the right choice.
Consider super king if: the room is 4m wide or more and partner disturbance is a significant ongoing problem. See our super king beds to compare.
Stay with a double if: the room is under 3.5m wide -- a king that dominates the space makes the room harder to live in daily, which cancels out the benefit.
| Type | Key Features | Best For |
|---|---|---|
| Ottoman | Gas-lift mechanism opens entire base upward; very high storage capacity at this size; no side clearance needed | Main bedrooms where storage is a priority -- at king size the ottoman footprint is proportionally greater than at double |
| Beds with Drawers | Built-in side or end drawers; easy daily access; no lifting required | Items accessed regularly without wanting to lift the full base |
| Divan | Solid upholstered base; lower profile; optional integrated drawers | Simple, practical setups -- often the best value at king size |
| Fabric / Upholstered | Padded headboard; wide colour and fabric range; soft finish | Main bedrooms where the bed is a visual centrepiece |
| Wooden | Solid or engineered wood; warm finish; quiet construction | Long-term everyday use in classic or contemporary rooms |
| Adjustable | Each side adjusts independently for position, angle, and support | Couples with different sleep preferences, back problems, or mobility needs |
| TV Bed | Motorised TV lift built into the footboard; rises and retracts electrically | Bedrooms where watching from bed is a regular rather than occasional habit |

Our team hears this from customers upgrading from a double more often than anything else: they did not realise how much they had been disturbing each other until they stopped. Dr Nerina Ramlakhan, Land of Beds' resident sleep physiologist, notes that partner disturbance is one of the most commonly underestimated causes of daytime fatigue in UK adults, frequently misattributed to stress when the solution is as practical as a larger bed.
At king size, the storage footprint is proportionally greater than at double. An ottoman king holds considerably more than an ottoman double -- enough for all bedding, seasonal clothing, and more.
| Storage Type | Capacity | What to Check |
|---|---|---|
| Ottoman | Maximum -- the entire under-bed footprint; no side clearance needed | Gas-lift weight limit -- check against your chosen mattress weight. Some models require a minimum mattress weight to operate correctly. |
| Side drawers | Medium -- easy daily access | Allow 60cm of clearance on the side the drawers open toward |
| End drawers | Medium to large | Allow clearance at the foot of the bed |
| No storage | None -- widest frame style choice | Under-bed storage boxes supplement well if needed |
| Budget | What You Get | Best For |
|---|---|---|
| Under £500 | Entry-level king frames -- basic materials, limited storage and style choice | Guest rooms or where budget is the primary constraint |
| £500 to £900 | Better construction, more storage options, wider style choice | A main bedroom king used regularly -- the entry point for everyday quality |
| £900 to £1,400 | Improved build quality, natural materials beginning, longer-lasting construction. Where most main bedroom buyers land. | Everyday use in a main bedroom -- durability and quality over years of daily use by two people |
| £1,400 and above | Premium and luxury construction, solid hardwood or high-end fabric, extended lifespan | Long-term investment in a master bedroom where quality is the priority |
For a main bedroom used nightly by two people, the quality gap between entry-level and mid-range is more noticeable at king size than at smaller sizes. The frame supports two people every night for years. A poor base shortens a good mattress's life -- match the frame quality to the mattress you are pairing it with.

| Question | Answer |
|---|---|
| What size is a king size bed in the UK? | A standard UK king size bed measures 150cm wide by 200cm long (5ft x 6ft 6in). This is 15cm wider and 10cm longer than a standard double. For two adults sharing, it gives each person approximately 75cm of personal space -- more than the 67cm each on a double, though still less than a full single bed width each. |
| Is a king size bed worth the upgrade from double? | For most couples in a room that takes it, yes. The extra 15cm of width means approximately 75cm per person compared to 67cm on a double -- a difference most couples feel clearly in terms of how much they disturb each other overnight. Measure the room first and allow 60cm of clearance on both sides. If the room takes a king comfortably, the upgrade is almost always worth it. |
| What room size do I need for a king size bed? | A room of approximately 3.5m x 3.5m gives a king comfortable clearance on both sides and at the foot. In rooms slightly smaller, a king can work with careful furniture planning, but measure twice before ordering. If the room is under 3.2m wide, a double is likely the more practical choice for day-to-day living. |
| Should I choose king or super king? | Measure the room first. A super king is 30cm wider than a king and needs approximately 4m x 4m. For most couples in a standard UK main bedroom, king is the right choice. Super king is worth considering if the room is genuinely large, partner disturbance is a significant ongoing problem, or very different mattress tensions are needed. See our super king beds to compare. |
| What is the best king size bed for couples? | For couples, an ottoman king where storage is the priority, or a fabric king in a design-led room, are the two most common choices. The type should follow whether storage capacity or room aesthetics is the primary concern. Frame quality matters more at king size because two people use it every night. |
| Do king size beds come with storage? | Yes -- ottoman and drawer options are available across a wide range of king size beds. At king size, the ottoman footprint is proportionally greater than at double, making it the highest-capacity storage option in a standard main bedroom. Drawers provide easier daily access for regularly used items. |
| How much does a good king size bed cost? | For a main bedroom used every night by two people, £900 to £1,400 is where most customers land. Below £500 is guest room quality. Above £1,400 you are investing in premium materials with a longer lifespan. At king size, the quality difference between budget tiers is more visible than at smaller sizes. |
| Do you offer free delivery on king size beds? | Yes. All king size beds come with free delivery to mainland UK addresses, no minimum spend. Professional bed assembly and old bed removal and recycling are both available as add-on services. |
| Can I buy a king size bed on finance? | Yes. Finance is available on eligible orders with repayment terms from 3 to 48 months. See our finance page for eligibility and how to apply. |
| What is the difference between a king ottoman and a king with drawers? | A king ottoman raises the entire mattress and base via a gas-lift, revealing the full under-bed storage. At king size this gives exceptional capacity -- enough for all bedding, duvets, and seasonal items -- with no side clearance required. A king with drawers provides easier daily access but needs 60cm of clearance on the opening side. In rooms where the bed sits close to a wall on either side, ottoman is often the more practical choice regardless of which you prefer on paper. |
