The flat sheet is the most debated bed linen item in hospitality. Its use varies enormously between establishments: it is practically universal in the American bed system — where it replaces the duvet cover — and increasingly optional in the European system — where the duvet with cover has displaced the flat sheet in many hotels. However, the flat sheet remains a relevant bed linen item for a significant proportion of European hospitality, particularly in upper-category hotels with a classic bed positioning and in establishments where laundry management makes the flat sheet preferable to the duvet system.
This guide explains when it makes sense to use a flat sheet in hospitality, which technical characteristics determine its quality and how to calculate the stock needed.
Flat Sheet vs Duvet System: When to Use Each
The Duvet System (European)
In the European system — predominant in the UK, Spain, France, Germany and Italy — the bed is made with a fitted sheet, an enclosed duvet and pillows. No flat sheet.
Advantages: shorter bed-changing time, cleaner and more contemporary visual appearance, less linen stock needed.
Disadvantages: the duvet can be too warm in summer or in warm climates; some guests — particularly those accustomed to the American system — prefer a flat sheet.
The American System (with Flat Sheet)
In the American system — common in Anglo-American chain hotels — the bed includes a fitted sheet, flat sheet, blanket or eiderdown and decorative bedspread. The flat sheet acts as an insulating layer between the guest's body and the blanket or eiderdown, which is laundered far less frequently.
Advantages: greater thermal versatility — the guest can use only the flat sheet in summer or add the blanket in winter — greater sense of luxury and a classic well-made bed, protection of the blanket or eiderdown that reduces its laundering frequency.
Disadvantages: longer bed-changing time — the flat sheet hem requires precision — greater linen stock, more items to manage in the laundry.
Technical Characteristics of a Good Hotel Flat Sheet
Fabric: Percale or Sateen
Percale cotton: the standard fabric in mid-to-upper-quality hotel flat sheets. Its matt finish and slightly crisp texture are characteristics the guest associates with a well-appointed hotel bed. Percale with 200–300 threads per square inch is the optimal range for hospitality.
Sateen cotton: the most luxurious fabric, with a slightly lustrous finish and exceptional feel. The standard in five-star hotels and luxury establishments. Requires greater care in laundering and pressing to maintain its finish.
Weight
The flat sheet weight should be slightly lower than the fitted sheet — the flat sheet does not receive the same level of direct friction from the mattress — but substantial enough to drape well and not crease with the guest's movement.
Recommended weight for hotel flat sheet: 120–160 g/m² in percale cotton. Below 120 g/m², the sheet is too light and semi-transparent; above 160 g/m², it may be too stiff.
The Hem: The Detail That Distinguishes the Hotel Flat Sheet
The top hem of the flat sheet — the part that is folded over the blanket or duvet and remains visible to the guest — is the most visible technical detail and the one with the greatest impact on the guest's perception of bed quality:
Plain hem: the most common in standard hospitality. Clean and functional.
Hem with drawn-thread work or embroidery: the highest-quality finish, common in luxury hotels. Drawn-thread work — a decorative stitch forming a line of small openwork — is the most classic finish in upper-category hospitality.
Hem with coloured stripe or embroidered logo: the most common personalisation in hotel chains wishing to reinforce their visual identity in the bed.
Sizes
- Single bed (90 cm): flat sheet 160x270 cm or 180x280 cm
- Double bed (135–150 cm): flat sheet 220x270 cm or 240x280 cm
- King-size bed (180 cm): flat sheet 260x280 cm or 280x290 cm
Laundry Management
The flat sheet is laundered at every guest change — the same as the fitted sheet — because it is in direct contact with the body.
Recommended minimum stock: 3 flat sheets per bed for establishments with their own laundry on 24-hour cycles; 4–5 for establishments with outsourced laundry.
Wash temperature: a minimum of 60°C to guarantee hygiene. Percale cotton withstands 60–90°C well; sateen requires lower temperatures to maintain its finish.
Pressing: the flat sheet requires pressing or calendering to maintain its impeccable appearance. Percale cotton is easier to press than sateen.
