Long Single Fitted Sheets

The most common reason a fitted sheet pulls free is that the depth is wrong for the mattress. Measure the total depth of your mattress including any topper and choose a sheet with a box depth that matches - a 30cm sheet on a 28cm mattress will have very little fabric to tuck under and will slip off. Belledorm fitted sheets have fully elasticated edges (not just corner elastic), which keeps the sheet anchored more securely around all four sides of the mattress.

Yes, UK double bed sheet dimensions are standardised: fitted sheets are 135cm x 190cm, flat sheets are 230cm x 275cm, and duvet covers are 200cm x 200cm. Belledorm's double range follows these standard UK dimensions throughout.

The one variable is fitted sheet depth, this is not standardised and varies by product and brand. Always check the box depth (30cm, 38cm, or 46cm) against your mattress measurement before purchasing. One common point of confusion is the duvet cover: a double duvet cover (200cm x 200cm) is square, not rectangular, this is correct and standard across the UK industry. If you are buying bedding as a gift or for a property you cannot measure, standard UK double dimensions apply to the overwhelming majority of double beds manufactured since 2000.

Belledorm's long single fitted sheets are sized for mattresses measuring 90cm x 200cm (3ft x 6ft 6in) - the same width as a standard single but 10cm longer, designed for taller adults who find a standard 190cm single mattress restrictive.

The long single shares the same width as a standard single (90cm) but is 10cm longer. A standard single fitted sheet (90cm x 190cm) will not fit a long single mattress, the sheet will be too short and pull free from the head or foot of the mattress.

A long single bed measures 90cm x 200cm. A standard single measures 90cm x 190cm, the same width but 10cm shorter. The two sizes use different fitted sheets which are not interchangeable, though duvet covers are the same size for both.

The 10cm length difference is specifically designed for adults over approximately 6ft (183cm) who find their feet overhang or touch the end of a standard 190cm single mattress. The long single is a common choice for tall teenagers, adults in single-occupancy rooms, and student accommodation built to accommodate taller residents. Standard single fitted sheets placed on a long single mattress will pull free from either the head or foot end - always confirm the sheet length (200cm) matches the mattress length.

A long single bed (90cm x 200cm) is the correct choice for adults over approximately 6ft (183cm) who find a standard single mattress (190cm) too short, as well as for anyone who prefers extra legroom when sleeping.

The standard rule is to choose a mattress at least 10-15cm longer than your height. For a 6ft (183cm) adult, a standard 190cm mattress provides only 7cm of clearance - insufficient for comfortable sleep. A 200cm long single mattress provides 17cm of clearance, which is more appropriate. Long single beds are also used in some European hotel and accommodation contexts where the 200cm length is standard. If you are buying a fitted sheet for a European-specification single mattress, the long single (90cm x 200cm) is the correct size.

Yes, a standard single duvet cover (135cm x 200cm) fits a long single bed correctly. The duvet cover length (200cm) matches the long single mattress length, making it the appropriate choice.

This is one of the practical advantages of the long single size: whilst the fitted sheet must be specifically sized at 90cm x 200cm, the duvet cover is the same as a standard single. The fitted sheet is the size-critical item - always confirm it is labelled as long single (90cm x 200cm) rather than standard single (90cm x 190cm). A standard single fitted sheet will be 10cm too short and will pull free from one end of a long single mattress.

To fully dress a long single bed, you need a long single fitted sheet, a standard single duvet cover, and one pillowcase. The fitted sheet must be specifically sized for the long single (90cm x 200cm).

The complete long single bed bedding list:

• Fitted sheet (90cm x 200cm) - must be specifically labelled as long single

• Duvet cover (135cm x 200cm) - standard single size fits correctly

• Pillowcase - standard UK pillow is 48cm x 74cm; one required

• Flat sheet (180cm x 290cm) - optional

• Mattress protector - recommended; confirm it is long single size (90cm x 200cm)

The fitted sheet and mattress protector are the items that must be specifically long single size. Duvet covers and pillowcases are standard single size.

Long single fitted sheets (90cm x 200cm) are a less common size than standard single, and not all brands stock them - always confirm availability and check dimensions carefully before purchasing.

The long single is sometimes listed as "extended single", "tall single", or "European single" by different retailers, though all refer to a 90cm x 200cm fitted sheet. The key compatibility check is the length: 190cm is standard single, 200cm is long single - a 10cm difference that makes the two non-interchangeable for fitted sheets. Duvet covers are interchangeable (both use 135cm x 200cm). If you are replacing a fitted sheet on an existing long single bed, measure the mattress length before ordering to confirm which size you need.
