Best Bed Size for a Guest Bedroom
The best bed size for a guest bedroom is usually a standard double (135x190cm / 4ft6) or a king (150x200cm / 5ft). These sizes offer good comfort for occasional guests while fitting most spare rooms without dominating the floor space.
Understanding UK Bed Sizes for Guest Rooms
UK mattress sizes are fixed: small single 75x190cm (2ft6), single 90x190cm (3ft), small double 120x190cm (4ft), double 135x190cm (4ft6), king 150x200cm (5ft) and super king 180x200cm (6ft). EU sizes differ (for example an EU double is 140x200cm). For guest bedrooms, avoid anything smaller than a double unless the room is very compact or you mainly host single visitors or children.
Measure your room carefully. Allow at least 75cm of clear space on each side of the bed for easy access and making the bed. Leave 90cm at the foot if guests need to walk past.
Double Beds: The Practical Choice for Most Guest Rooms
A double bed is the most common choice for guest bedrooms. At 135x190cm it sleeps two adults comfortably for short stays and leaves more room for wardrobes or chest of drawers. It is also easier to fit standard bedding and fits through most doorways during delivery.
Check the room shape. If the bedroom is narrower than 250cm, a double is usually the safer option. Many homeowners choose a storage double to keep spare bedding and towels close at hand without needing extra furniture.
When a Double is Not Enough
If guests often stay for more than a few nights or include taller adults, consider stepping up to a king. The extra 15cm in width and 10cm in length makes a noticeable difference to sleep quality without requiring a much larger room.
King Size Beds: Extra Comfort When Space Allows
A king size bed (150x200cm) is ideal if your guest room measures at least 3.5m by 3m. It gives visitors more space to stretch out and is particularly useful for couples. Browse our range of king size beds and pair with a supportive king size mattress for the best guest experience.
Trade-off: a king takes up more floor area than a double. Use a checklist: measure the room, subtract 150cm width and 200cm length, then check at least 75cm remains on the sides and 90cm at the foot. If the remaining space feels tight, stick with a double.
Guest Beds and Folding Options for Flexible Space
For rooms that double as home offices or hobby spaces, a dedicated guest bed may be too permanent. Guest beds that fold away or have a trundle solve this. Look at models such as the Flair Yuma Boucle Guest Bed or the Noomi Erika Guest Bed with Drawer. These provide a comfortable double surface when needed and store compactly.
Metal guest beds and folding beds are also popular. The Jay-Be Crown Premier Folding Guest Bed assembles quickly and can be put away after use. Always confirm the mattress depth matches the bed maker’s maximum recommended depth so guard rails (if any) remain compliant with BS EN 747.
Space-Saving Furniture to Complement Your Guest Bed
Once the bed size is chosen, add practical pieces that maximise the remaining space. A compact bedside table on each side, a narrow ottoman blanket box at the foot, or a chest of drawers against a short wall all help. For larger rooms, an ottoman bed gives hidden storage for extra pillows and duvets.
Practical checklist before buying:
- Measure the room twice – length, width and diagonal for delivery.
- Decide maximum bed footprint you can accept.
- Choose mattress type that matches expected guest needs (firmer for back support, softer for side sleepers).
- Check fire safety labels – all UK mattresses meet BS 7177.
- Confirm the bed frame meets British safety standards if it has any raised sections.
Super King and Other Larger Options
A super king (180x200cm) is rarely the best bed size for a guest bedroom unless the room is 4m wide or more. The extra width reduces circulation space dramatically in most spare rooms. Only choose this if your measurements confirm at least 90cm clearance all round.
For children or single adult guests, a single or small double can work well and free up significant floor area for a desk or chair. Many families keep a metal guest bed that can be moved between rooms as needed.
| Bed Size | Dimensions (cm) | Best For Guest Rooms | Minimum Room Size Suggestion |
|---|---|---|---|
| Double | 135x190 | Most spare bedrooms | 285x265cm |
| King | 150x200 | Longer stays, taller guests | 300x275cm |
| Super King | 180x200 | Large rooms only | 330x280cm |
| Guest/Folding | Varies | Multi-use rooms | Depends on folded size |
Final Decision Rules
Use this simple rule: choose the largest bed that still leaves 75cm clearance on at least one long side and 90cm at the foot. If two adults will share the bed regularly, go for king if the room allows; otherwise a well-made double with a quality mattress is the sweet spot for nearly all guest bedrooms. Consider adding storage solutions such as the Kyoto Belle Ottoman Bed if you need to keep the room tidy between visits.

Frequently asked questions
Can I use a single bed in a guest bedroom?
Yes, a single (90x190cm) works well if you mainly host one person or children. It leaves the most floor space for other furniture but is less versatile for couples. A small double (120x190cm) is a better middle ground for occasional adult guests.
How much clearance do I need around a guest bed?
Leave at least 75cm on each long side for easy access and bed-making. Allow 90cm at the foot if people need to walk past. These clearances prevent the room feeling cramped and help with vacuuming or changing sheets.
Are folding guest beds comfortable for adults?
Modern folding guest beds with proper mattresses can be very comfortable for short stays. Look for models with a sprung base or memory foam topper. Always check the mattress depth does not exceed the manufacturer’s stated maximum.
Should I choose an ottoman bed for a guest room?
An ottoman bed is excellent if you need extra storage for spare bedding, towels or seasonal clothes. The lift-up base keeps the room tidy without taking extra floor space. Just ensure the mechanism does not obstruct normal walking routes.
What is the difference between UK and EU bed sizes for guests?
UK double is 135x190cm while an EU double is usually 140x200cm. UK king is 150x200cm. If buying continental bedding make sure it fits your chosen UK frame. Most UK guest rooms are built around British sizes so stick with those unless you have specific imported furniture.
