Emperor Bed Size Guide: Dimensions, Sheets & Duvets
An Emperor bed gives you considerably more sleeping space than a standard UK king or super king. However, choosing the correct bed linen is not always straightforward because the name “Emperor” is used for several different mattress dimensions.
The most common Emperor mattress measures 200 x 200cm, but you may also encounter beds measuring 215 x 200cm or 215 x 215cm. These are sometimes described as Large Emperor, 7ft Emperor or short 7ft beds.
This guide explains the different Emperor bed sizes and helps you choose the correct fitted sheets, mattress protectors, duvets and duvet covers. If you already know your measurements, you can browse our complete range of Emperor bedding.
The most important thing to know
Do not rely on the name “Emperor” alone. Measure the width, length and depth of your mattress before ordering bedding, as Emperor beds are not produced to one universal size.
What size is an Emperor bed?
A standard Emperor bed usually measures 200cm wide by 200cm long. This is approximately 6ft 6in square and is larger than a UK super king, which measures 180 x 200cm.
There are also two larger variations measuring 215cm wide. Depending on the manufacturer, these may be called Large Emperor, 7ft Emperor or short 7ft beds.
| Common name | Metric size | Approximate imperial size |
|---|---|---|
| Emperor | 200 x 200cm | 6ft 6in x 6ft 6in |
| Short 7ft or Large Emperor | 215 x 200cm | Approximately 7ft x 6ft 6in |
| 7ft or Large Emperor | 215 x 215cm | Approximately 7ft x 7ft |
Bed manufacturers do not always use these names consistently. A bed advertised as “Large Emperor” could therefore be 215 x 200cm or 215 x 215cm. Always check the actual mattress measurements.
Emperor vs Large Emperor: what is the difference?
A standard Emperor mattress is normally 200 x 200cm. A Large Emperor is wider at approximately 215cm, but its length may be either 200cm or 215cm.
This relatively small difference is important when purchasing a fitted sheet or mattress protector. A fitted product made for a 200 x 200cm mattress will not fit properly around a 215cm-wide bed.
If you have a 215cm-wide mattress, see our 7ft and Large Emperor bedding, or contact us with the exact measurements if you are unsure.
Is an Emperor bed the same as a 7ft bed?
Not necessarily. A standard Emperor is approximately 6ft 6in square, while a full 7ft bed measures approximately 215 x 215cm.
Some retailers use “Emperor” as a general description for both sizes, which is one reason customers can receive bedding that does not fit. The safest approach is to ignore the name temporarily and confirm these three measurements:
- Mattress width – measured from side to side
- Mattress length – measured from head to foot
- Mattress depth – including any permanently used topper
How does an Emperor compare with other UK bed sizes?
| Bed size | Mattress dimensions | Difference from a 200 x 200cm Emperor |
|---|---|---|
| UK king | 150 x 200cm | 50cm narrower |
| UK super king | 180 x 200cm | 20cm narrower |
| Emperor | 200 x 200cm | — |
| Large Emperor/short 7ft | 215 x 200cm | 15cm wider |
| Full 7ft/Large Emperor | 215 x 215cm | 15cm wider and 15cm longer |
How does an Emperor compare with even larger beds?
An Emperor is not the largest oversized bed available. If you need more sleeping space, there are several larger and less standardised options.
| Bed size | Typical mattress dimensions |
|---|---|
| Emperor | 200 x 200cm |
| Large Emperor/7ft | 215 x 200cm or 215 x 215cm |
| Caesar | Approximately 245 x 200cm |
| Alaskan King | Dimensions vary between manufacturers |
Names and dimensions for oversized beds are not completely standardised. Always confirm the mattress width and length before ordering. For a fuller comparison, read our guide to Alaskan King, Caesar and Emperor beds.
For a more detailed comparison of the two most commonly confused sizes, read our guide to Emperor beds vs super king beds.
What fitted-sheet size does an Emperor bed need?
Your fitted sheet should match the mattress width and length. For a standard Emperor mattress, choose a 200 x 200cm fitted sheet. A 215 x 200cm or 215 x 215cm mattress needs a sheet made specifically for those dimensions.
Depth is equally important. Measure from the bottom seam of the mattress to its highest point, including a mattress topper if it remains on the bed. Choose a fitted sheet with a pocket comfortably deeper than the total mattress depth so there is sufficient fabric to tuck beneath it.
Victoria Linen makes Emperor fitted sheets in different mattress dimensions and depths, including deeper options for pillow-top mattresses and beds with toppers.
Can I use a super king fitted sheet on an Emperor bed?
No. A UK super king fitted sheet is designed for a 180 x 200cm mattress, making it approximately 20cm too narrow for a standard 200 x 200cm Emperor mattress. Stretching a smaller fitted sheet over the bed can strain the seams, cause the corners to lift and create an uncomfortable sleeping surface.
What size duvet fits an Emperor bed?
Our standard Emperor duvet measures 290 x 235cm. This provides more width than a super king duvet and creates a more generous drop over the sides of a 200cm-wide mattress.
The best duvet size can also depend on:
- Whether one or two people use the bed
- The height and depth of the mattress
- How much overhang you prefer
- Whether the bed has a deep upholstered frame
- Whether you tend to pull the duvet during the night
A larger bed does not automatically require the warmest duvet. The tog rating determines warmth, while the dimensions determine coverage. Explore our Emperor duvets to compare available fillings and tog ratings.
What size duvet cover does an Emperor duvet need?
The duvet cover should match the dimensions of the duvet rather than the mattress. A Victoria Linen Emperor duvet measuring 290 x 235cm therefore requires an Emperor duvet cover in the same 290 x 235cm size.
Do not assume that every product labelled “Emperor” uses identical measurements. Check the label or measure your existing duvet before ordering a replacement cover.
Our Emperor duvet covers are made for oversized duvets and are available in a choice of easy-care, cotton and luxury fabrics.
What other bedding does an Emperor bed need?
Once you have confirmed the mattress dimensions, you can select each item individually or choose coordinating bed linen.
Emperor mattress protectors
A mattress protector should match both the surface dimensions and depth of the mattress. This is particularly important for Emperor mattresses because replacing an incorrectly sized or damaged mattress can be expensive.
See our Emperor mattress protectors for quilted and protective options in oversized dimensions.
Emperor flat sheets
A flat sheet must provide enough fabric to cover the mattress and tuck securely beneath the sides and foot. Standard king and super king flat sheets may not offer sufficient width for an Emperor bed.
Our Emperor flat sheets are generously proportioned for larger mattresses.
Emperor sheet sets
A coordinated sheet set is a convenient way to purchase a fitted sheet, flat sheet and pillowcases in the same fabric and colour. Check the contents of each set, as a sheet set does not normally include a duvet or duvet cover.
Browse our Emperor bed sheet sets for matching oversized bed linen.

If you need to dress a new bed from scratch, a complete bundle can bring the principal pieces together while helping you avoid mixing incompatible sizes.

How to measure an Emperor mattress
Use a firm tape measure and remove loose bedding before starting.
- Measure the width: measure straight across the widest part of the mattress.
- Measure the length: measure from the head to the foot of the mattress.
- Measure the depth: measure vertically from the bottom edge to the highest point.
- Include a topper: if it remains on the bed beneath the fitted sheet, include it in the depth.
- Measure the duvet separately: duvet covers are selected using duvet dimensions, not mattress dimensions.
Small variations can occur, particularly with handmade, upholstered or bespoke beds. If your mattress does not match a recognised size, contact us with the exact measurements. As UK bedding manufacturers, we can produce made-to-measure fitted sheets for unusual mattress dimensions and depths.
Is an Emperor bed right for your bedroom?
An Emperor bed can be a good choice for couples who want more personal sleeping space or families who occasionally share the bed with children. Its square proportions can also create an impressive focal point in a generously sized bedroom.
Before buying one, consider more than the mattress dimensions. Allow room for the bed frame, bedside furniture, wardrobes and comfortable movement around the room. You should also check doors, staircases and access routes because Emperor frames and mattresses can be difficult to manoeuvre.
Advantages of an Emperor bed
- More individual sleeping space for couples
- Plenty of room for occasional family co-sleeping
- A luxurious appearance in a large bedroom
- Square proportions suited to spacious interiors
- Less disturbance when one person changes sleeping position
Points to consider
- The bed and surrounding frame require considerable floor space
- Access and delivery may be more difficult
- Standard king or super king bedding will not fit correctly
- Several different dimensions are sold under similar names
- Specialist bedding can cost more than standard UK sizes
How to style an Emperor bed
The generous width of an Emperor bed gives you room to layer a fitted sheet, flat sheet, oversized duvet, pillows and a restrained selection of cushions or throws. Keeping the layers in proportion helps the bed feel luxurious without looking overcrowded.
