A bigger bed can transform the way a bedroom feels. It gives two sleepers more personal space, creates a natural focal point and can bring the proportions of a generous room into balance.
The important question is not simply, “What is the biggest bed I can buy?” It is, “Which bed will work properly in this room, reach the room safely and still leave the space comfortable to use?”
At Revival Beds, we have been handcrafting wooden beds in Nottinghamshire since 1983. Our collection includes sizes from Single to 8ft Caesar, as well as made-to-measure options. Available sizes and changes depend on the design, so confirm the specification for your chosen bed. In this guide, we explain the differences between Super King, Eastern King, Emperor and Caesar beds, then share the practical checks our team considers before a large bed is made and delivered.
Big bed sizes at a glance
The measurements below describe the mattress size, not the full outside dimensions of the bed frame. A sleigh bed, four-poster or substantial headboard and footboard will add to the overall width or length, so always check the product’s external dimensions before ordering.
| UK bed size | Mattress width | Mattress length | Best suited to |
|---|---|---|---|
| King | 5ft | 6ft 6in | Couples wanting more space without dominating a medium-sized room |
| Super King | 6ft | 6ft 6in | Couples who value generous personal space |
| Eastern King | 6ft 6in | 6ft 6in | A square sleeping surface and a spacious principal bedroom |
| Emperor | 7ft | 6ft 6in | Large bedrooms where scale and comfort matter equally |
| Caesar | 8ft | 6ft 6in | Very large rooms and customers comparing Revival’s 8ft option |
These are Revival’s named mattress-fit sizes. Confirm exact centimetre measurements for your order; size labels can vary between suppliers.
If you need additional length rather than width, do not assume a larger named size will solve the problem: these standard large sizes remain 6ft 6in long. A made-to-measure bed and mattress may be the better answer.
Is a Super King, Emperor or Caesar right for you?
Choose a Super King when you want a noticeable step up
A Super King is one foot wider than a standard King. That extra width can make a meaningful difference for two people, yet it is still a familiar size with a broad choice of mattresses and bedding.
It is often a sensible starting point for a principal bedroom. The frame still needs to be measured carefully, particularly if it has a curved sleigh-bed profile or a wide headboard, but it will suit more rooms than an Emperor or Caesar.
Choose an Emperor when the room needs greater scale
At 7ft wide, an Emperor gives each person abundant sleeping space. It also has enough visual presence to feel properly proportioned in a large bedroom where a smaller bed might look lost.
The extra width affects more than the bed itself. Bedside cabinets sit further apart, rugs need to be large enough, and the route around the bed must remain practical. It is worth planning the whole arrangement rather than placing an Emperor in the room and working around it afterwards.
Choose a Caesar when width is the priority
Caesar is Revival’s named 8ft-wide mattress-fit option. Ask the team about any larger bespoke request. It creates an impressive centrepiece and an exceptionally generous sleeping area, but it needs a room and access route that can accommodate the complete design.
Remember that “8ft” describes the mattress width. Decorative posts, side rails and the shape of the headboard or footboard can make the finished frame wider or longer. Use the external product dimensions for your floor plan.
Eight checks before you order a larger bed
1. Measure the bed frame, not only the mattress
Mattress sizes provide a useful comparison, but they are not a substitute for the bed frame’s overall dimensions. Two beds designed for the same mattress can have very different footprints.
Before you decide, ask for:
- the maximum outside width;
- the maximum outside length;
- the headboard and footboard height;
- the space required by any under-bed drawers; and
- the size of the largest component that must reach the bedroom.
Those figures give you a much more reliable picture of how the bed will look, fit and be delivered.
2. Mark the full footprint on the floor
Use low-tack masking tape, sheets of paper or flattened cardboard to mark the frame’s outside dimensions in the room. This simple exercise is more useful than trying to imagine the size from a tape measure alone.
Then walk around the outline as you would use the room every day. Open the bedroom door, wardrobes and drawers. Check the route to the window and allow space for curtains, radiators and bedside furniture. If two people will use the bed, make sure both sides remain convenient.
If the room is empty, add the footprint of your planned furniture to the same sketch. A large bed should make the room feel generous, not turn every movement into a squeeze.
3. Check height as well as floor space
A tall headboard or four-poster changes the way a bed fits vertically. Measure ceiling height and note sloping ceilings, beams, picture rails, sockets and wall lights. If the bed will sit below a window, compare the headboard height with the sill.
This is especially important in period properties and converted lofts, where the largest area of floor may not have the most usable headroom.
4. Plan the complete access route
The bedroom may be large enough while the route to it is not. Measure from the entrance to the final position, paying attention to:
- the narrowest doorway;
- tight turns in halls or on landings;
- staircase width and the space above the stairs;
- low ceilings, beams and bulkheads;
- fixed banisters and radiators; and
- lifts, communal entrances or restricted parking where relevant.
A bed made in sections is easier to move than a one-piece frame, but its largest components still need to pass safely through every turn. Share photographs and measurements with the supplier before production if any part of the route looks tight.
Revival’s delivery team installs beds every day, including large and unusual sizes. Discussing access early allows the workshop and delivery team to identify potential problems before the bed arrives.
5. Choose the mattress at the same time
Larger mattresses are specialist items. Confirm the exact size, depth, firmness and delivery route before you commit to the frame. A mattress must not only fit the bed; it must also reach the bedroom.
Think about how it will be handled in future, too. Follow the care instructions for the particular mattress and plan how it will be handled; a large mattress may require assistance. A zip-link mattress can be easier to move and can also allow different levels of firmness on each side, depending on the mattress specification.
Buying the bed and mattress from the same specialist supplier helps remove uncertainty over dimensions and delivery timing.
6. Look beneath the mattress at the support system
The scale of the frame should be matched by appropriate support. Ask how the slats are made and fixed, whether a centre rail is included, and how the joints are secured.
Every Revival bed comes with 18 solid pine slats. Beds above 4ft 6in Double are supplied with a centre bar as standard. The slats are pre-drilled and secured to the frame, helping the bed and mattress work together as a stable system.
Do not judge a large bed by its headboard alone. The parts you cannot see—the slats, centre support, joints and fittings—are central to how the frame performs in everyday use.
7. Decide whether the footprint should provide storage
A larger bed occupies valuable floor area, so under-bed drawers can make that space work harder. They can be useful for spare bedding, seasonal clothing and other items that would otherwise need another piece of furniture.
Check the direction in which drawers open and mark their full travel on your plan. A drawer is only useful if it clears bedside furniture, walls and walkways. In a tighter room, drawers on selected sides may be more practical than a symmetrical arrangement.
8. Ask who will deliver and install it
Confirm which delivery and assembly tasks are included for the particular bed. Before ordering, find out whether delivery includes installation, who carries it out and what happens if the team identifies an access issue.
Revival describes free UK mainland delivery and installation, subject to its published location exceptions. Check the delivery FAQ for your address and confirm who will deliver and install your order. Where installation is included, the team assembles the bed in the chosen room. Our bed frames are covered by a 10-year guarantee against manufacturing defects, subject to the guarantee terms.
What if none of the standard sizes is quite right?
Named sizes are useful, but they should not force a compromise. You may need extra length for a taller sleeper, a particular width to suit an alcove or changes to the frame so it works with an unusual room or access route.
Because Revival beds are handmade to order, made-to-measure options are available. The bed, mattress and bedding can be considered together, avoiding the mismatch that can occur when non-standard elements are sourced separately.
The best time to discuss a change is before production. Bring your measurements, photographs and any concerns to our team, or visit the Nottinghamshire showroom to compare designs at full scale.
Frequently asked questions
What is the biggest standard bed size in the UK?
Names can vary between suppliers, so dimensions matter more than the label. In the Revival collection, a Caesar mattress-fit size is 8ft wide and 6ft 6in long. Always check the external dimensions of the chosen frame as well.
How much bigger is an Emperor than a Super King?
An Emperor is 7ft wide, while a Super King is 6ft wide. Both are normally 6ft 6in long, giving the Emperor one foot of additional width.
Is a Caesar bed bigger than an Emperor?
Yes. A Revival Caesar is 8ft wide and an Emperor is 7ft wide. They share the same standard 6ft 6in mattress length.
Will a Caesar bed fit upstairs?
It may, because the bed frame is delivered in sections and assembled in the bedroom. Access still depends on the chosen design and the dimensions of doorways, stairs, landings and overhead obstructions. Check the route with the supplier before the bed is made.
Can a large bed be made extra long?
Yes. Super King, Eastern King, Emperor and Caesar describe different standard widths, but their standard length is 6ft 6in. Revival can discuss a made-to-measure bed, mattress and bedding when additional length is required; available changes depend on the design.
