Need a made to measure flat sheet?
We specialise in custom size flat sheets made to measure for mattresses that do not suit standard UK sizes. If your mattress is longer, wider or a bespoke size, we can make a flat sheet to suit.
If you want a top flat sheet you may prefer a smaller size, usually closer to the duvet size, as it does not need to tuck underneath.

Extra Long, Emperor & Custom Flat Sheet FAQs
Do you make extra large flat sheets?
Yes. We supply extra large and extra long flat sheets, including Emperor and Caesar flat sheet sizes, and we stock flat sheets in our standard bed linen ranges.
What size Emperor flat sheet do I need?
For an Emperor flat sheet, first check your mattress width. A Small Emperor or Eastern King mattress is usually 200cm wide, while a Standard Emperor mattress is usually 215cm wide. Our Small Emperor flat sheet is 305 x 305cm, while our Standard Emperor / Caesar flat sheet is 350 x 350cm.
Can I order a custom size flat sheet?
Yes. We can make a custom size flat sheet to any size for a non-standard bed or bespoke mattress. Contact us with your mattress width, length and depth and we can advise on the best size.
Should I choose my flat sheet by mattress size?
Yes. On our bed linen pages, choose your fabric and then select by mattress size. The flat sheet is made larger than the mattress so it can tuck under the mattress or drape over the bed.
Is a top flat sheet the same size as a bottom flat sheet?
Not always. A bottom flat sheet normally needs extra fabric so it can tuck under the mattress. A top flat sheet does not need to tuck underneath, so you may prefer a smaller size, usually closer to your duvet size.
What flat sheet sizes do you offer for larger beds?
Our larger flat sheet options include Single 200 x 275cm, Prince 245 x 275cm, King 275 x 275cm, Super King 305 x 305cm, Small Emperor or Eastern King 305 x 305cm, and Emperor or Caesar 350 x 350cm.
