  • Double: 135-140 × 190-200 cm (53.1-55.1″ × 74.8-78.7″)

  • King: 180-200 × 200 cm (70.9-78.7″ × 78.7″)

Cultural Considerations

Beyond standard measurements, several cultural factors influence mattress sizes globally:

  • Traditional Floor Bedding: Many Asian cultures traditionally use floor bedding (Japanese futons, Korean yo, etc.) rather than raised mattresses.
  • Co-Sleeping Practices: In countries where family co-sleeping is common, larger mattress sizes or custom family beds may be more prevalent.
  • Height Adaptations: Northern European countries often offer longer mattresses to accommodate taller average heights.
  • Space Constraints: In densely populated urban areas like Tokyo, Hong Kong, and major European cities, compact mattress sizes are more common due to smaller living spaces.
  • Climate Factors: In tropical regions, thinner mattresses with better ventilation are preferred for temperature regulation.

Shopping Internationally

When purchasing a mattress from another country or region, consider:

  • Exact Measurements: Always check the precise centimeter measurements rather than relying on size names.
  • Bedding Compatibility: Sheets and bedding designed for one regional standard may not fit mattresses from another region.
  • Room Dimensions: Ensure your bedroom can accommodate a mattress sized to different standards.
    Foundation Differences: Bed frames and foundations may be designed specifically for regional mattress dimensions.
  • Thickness Variations: Beyond length and width, mattress thickness can vary significantly between regions.

This diverse range of mattress sizes across the globe reflects the unique sleeping preferences, available living spaces, and cultural traditions that shape how we rest across different regions.

International Comparison

When comparing across countries, it’s important to note that even similarly named sizes can have different dimensions. For example, a UK Double is smaller than a US Full/Double, and a UK King is smaller than a US King.

Choosing the Right Size

When selecting a mattress size, consider:

  1. Room dimensions (allow at least 2 feet of walking space around the bed)
  2. Sleeper height (taller individuals should consider XL or California King options)
  3. Number of sleepers (couples typically need at least a Queen)
  4. Sleeping style (active sleepers need more space)
  5. Future needs (children, pets, or family changes)

By understanding the differences between mattress sizes across these countries, you can make a more informed choice that suits your sleeping needs, room dimensions, and budget constraints.
