Generously sized flat sheets for Emperor beds
An Emperor flat sheet must be considerably larger than the mattress itself. The additional fabric creates the side drop and provides enough material to tuck beneath the sides and foot of the mattress.
A standard Emperor mattress measures approximately 200 x 200cm, while larger beds described as 7ft or Large Emperor may measure 215 x 200cm or 215 x 215cm. Standard king and super king flat sheets may not provide enough width for these oversized beds, particularly when the mattress is deep.
What size is an Emperor flat sheet?
| Bed description | Mattress dimensions | Typical flat-sheet size |
|---|
| Standard Emperor | 200 x 200cm | Approximately 290 x 267cm
114 x 105in |
| Short 7ft/Large Emperor | 215 x 200cm | Depends on mattress depth and preferred drop |
| 7ft/Large Emperor | 215 x 215cm | Approximately 305 x 292cm
120 x 115in |
These are typical Victoria Linen dimensions, but available sizes may differ between fabrics and individual products. Check the stated dimensions before purchasing, particularly if you have a deep mattress or intend to use the sheet as a bottom sheet.
For fitted products that match the mattress surface and depth exactly, see our Emperor fitted sheets.
Should you use an Emperor flat sheet as a top or bottom sheet?
An Emperor flat sheet can be used in either position.
Using it as a top sheet
Place the flat sheet between you and the duvet, with the finished top edge towards the head of the bed. A top sheet can:
- Create a lighter layer during warmer weather
- Help keep the duvet cover fresher for longer
- Provide the crisp, layered appearance associated with hotel beds
- Allow one layer to be removed or added during the night
Using it as a bottom sheet
A flat sheet can also cover the mattress instead of a fitted sheet. It must be wide and long enough to tuck securely beneath the mattress at the sides and foot.
Some customers prefer a flat bottom sheet because it can be folded neatly for storage, does not have elasticated corners and can be easier to press. However, it generally requires more time to make the bed and may move more than a correctly sized fitted sheet.
How mattress depth affects flat-sheet size
Mattress depth matters even though a flat sheet does not have fitted corners. A deeper mattress uses more of the sheet’s width before any fabric reaches beneath it.
For example, two mattresses may both measure 200 x 200cm across the surface, but a 40cm-deep mattress needs more sheet width than a 25cm-deep mattress to achieve the same side tuck.
Before ordering, measure:
- The mattress width
- The mattress length
- The complete mattress depth
- Any topper that remains beneath the sheet
- Your preferred amount of side drop or tuck
If you are using the sheet purely as a top sheet, decide whether you want it to sit level with the mattress edge or hang further down the sides. If you are using it as a bottom sheet, allow sufficient fabric to tuck beneath the mattress.
How much fabric should tuck beneath the mattress?
For a bottom sheet, aim to have a useful amount of fabric beneath both sides of the mattress after its depth has been covered. A very small tuck may pull free when you move during the night.
The amount required depends on the mattress weight, depth and surface, but around 15–20cm beneath each side is a practical starting point. More may be helpful for a lighter mattress or an active sleeper.
Deep mattress? Tell us the mattress width, length and depth and whether the sheet will be used on top or underneath. We can help you select an appropriate size or make a custom Emperor flat sheet.

Frequently asked questions
What size is an Emperor flat sheet?
Our standard Emperor flat sheet is approximately 290 x 267cm, or 114 x 105in, for a 200 x 200cm mattress. Larger 7ft options may measure approximately 305 x 292cm, or 120 x 115in. Check the individual product dimensions before ordering.
Is an Emperor flat sheet the same size as the mattress?
No. A flat sheet must be larger than the mattress to provide a side drop or enough material to tuck underneath it.
Can an Emperor flat sheet be used as a top sheet?
Yes. Place it between the sleeper and the duvet to add a lighter layer, help protect the duvet cover and create a traditionally layered bed.
Can I use an Emperor flat sheet as a bottom sheet?
Yes, provided it is large enough to cover the mattress depth and tuck securely beneath the sides and foot.
What size flat sheet do I need for a deep Emperor mattress?
Measure the mattress width, length and depth. A deeper mattress requires a larger flat sheet to achieve the same side drop or tuck. Contact us if the listed product size does not provide enough fabric.
Will a super king flat sheet fit an Emperor bed?
It may cover the top surface, but it is unlikely to provide the same side drop or secure tuck as a flat sheet made for a 200cm-wide Emperor mattress. Check the actual sheet dimensions rather than relying on the size name.
Do you make 7ft flat sheets?
Yes. We offer oversized flat sheets for 215cm-wide beds, including mattresses described as 7ft or Large Emperor. You can also browse our 7ft bedding collection.
Can you make a custom Emperor flat sheet?
Yes. Provide the mattress width, length and depth, together with your preferred side drop or tuck, and we can make a flat sheet to suit.
Are fabric samples available?
Yes. Contact us if you would like to compare colours and fabrics before ordering an Emperor flat sheet.
