In this guide, we compare king size and double beds, covering dimensions, comfort, storage, and more to help you decide which option is best for your space and lifestyle.
Is a King Size Bed Bigger Than a Double Bed?
Absolutely! A king size storage bed is larger than a double bed. In the UK, a standard king size bed measures approximately 150cm x 200cm (5ft x 6ft6), while a double bed usually measures around 135cm x 190cm (4ft6 x 6ft3). That extra space about 15cm in width and 10cm in length can make a significant difference in your comfort and sleep quality.

Comfort & Sleeping Experience: Which One Feels Better?
King Bed
-
Feels roomy and luxurious; partners can stretch out without bumping elbows.
-
Extra width reduces motion transfer-related disturbances.
-
Larger surface area improves temperature regulation (more space for sheets to breathe).
Double Bed
-
Creates a snug, cozy feel—great for solo sleepers or teens.
-
Slightly closer quarters for couples; may feel warmer on hot nights.
-
Easier to keep bedding taut and tucked for a neat look.
Choose a king if nightly sprawl-room and partner comfort top your list; pick a double if you like a tucked-in, intimate sleep space.
Customisation and Storage Options
Both king and double beds offer various customisation and storage features:
-
Fabrics & Colours: Personalise your bed with a variety of upholstery options.
-
Headboard Styles: Choose from classic, minimalist, or bold statement designs.
-
Storage Solutions: Integrated drawers or ottoman lifts help keep your room clutter-free.
-
Accessories: Coordinate bedding, pillows, and bedside furniture for a cohesive look.
Tip: Use design tools or consult your retailer to tailor your bed to your unique style and space.
Which Bed Is Right for You?
Choosing between a king and a double bed depends on your room size, lifestyle, and storage needs:
Floor-Plan Requirements
-
King: Allow at least 60 cm (≈ 2 ft) clearance on all accessible sides—best suited to master bedrooms.
-
Double: Fits comfortably in smaller rooms; still leave ~60 cm on the sides you’ll access frequently.
Budget Considerations
-
King: Higher price point for mattresses, frames, and linens.
-
Double: More economical overall; accessories are widely available and cheaper.
Storage & Bed Variants
-
Both sizes offer ottoman or divan versions for under-bed storage.
-
In cramped rooms, a double ottoman can offset the smaller footprint by adding hidden capacity.
Quick Verdict:
Opt for a king bed if your room is spacious and you’re willing to invest in larger furniture and bedding for maximum comfort.
Opt for a double bed when floor space or budget is limited, or you’re furnishing a guest room or secondary bedroom.
Conclusion: King vs Double Bed – Which Size Suits You?
A king bed adds 15 cm of width and 10 cm of length over a double, delivering luxurious sprawl-room and superior partner comfort—but it demands more floor space, higher bedding budgets, and larger accessories.
A double, meanwhile, offers a snug, cost-efficient solution that fits neatly into smaller bedrooms or guest spaces without sacrificing quality sleep.
Both sizes come in divan and ottoman variants, so factor in storage needs alongside room dimensions and budget before deciding which mattress footprint best supports your lifestyle.
