Bed Size

Bed sizes refer to the standardized dimensions of mattresses and bed frames, which vary by country and region. Common sizes include single (twin), double (full), queen, and king, but exact measurements differ internationally. Bed size affects comfort, room layout, and bedding selection.

Common Bed Sizes

• Single/Twin: Typically 90 x 190 cm (35 x 75 in) in Europe,[^1] approximately [38" to 60"] width for twin sizes globally[^2]. These standards are commonly used but not always strictly enforced, leading to variations within regions.
• Double/Full: 135 x 190 cm (53 x 75 in) typically in the UK and Europe,[^3] while US Full is around [54" width][^4]. However, some brands offer "Extra Long Double", but these are not universally standardized.
• Queen: Defined as approximately [60" to 80"] with varying lengths across regions[^5]; common measurements include 152 x 203 cm in the UK and Europe. While typically consistent within standards, specific regional variations may exist (e.g., California queen).
• King: US King is around [76" width][^6] at standard depths; however, it can vary considerably by brand or region without being part of an international standard.

Other sizes include super king and California king. See Bed for more on types of beds.

International Variations

Bed and mattress sizes are not fully standardized worldwide. While some standards provide typical dimensions (like the examples above), regional practices often influence final measurements, leading to variations even within countries or continents. For instance, while queen bed is standard in UK with 152 x 203 cm being common, other beds like twin extra long may not follow strict definitions.

[^1]: European Standardization (e.g., via CEN), often around EN ISO standards. [^2]: ANSI/ISO Standards vary; single/twin is common in US but defined by regional practices. [^3]: UK Bed Size Standards are typically part of BSI guidelines, and used across Europe. [^4]: American National Standards Institute (ANSI) recommendations for twin mattresses. [^5]: Queen size often follows the Euro standard or slightly smaller variants within regions; measurements depend on specific standards like those from CEN or ANSI. [^6]: King sizes primarily defined by US furniture industry standards.
