When furnishing luxury homes across borders, few details trip up even seasoned estate managers like international mattress sizes. A king bed in New York is not the same as a king bed in London, and a “queen” in Dubai may be closer to a European double. For global estate owners, hospitality professionals, or anyone curating interiors for an international clientele, understanding these differences is essential. The right bed size ensures comfort, avoids costly replacements, and preserves the design flow of bedrooms in multi-country properties.

This guide breaks down the US, UK, EU, and Middle Eastern bed size standards, explaining how they differ, why it matters, and how to make the smartest selections for international estates.
Why Bed Size Standards Differ Around the World
Bed dimensions vary for several reasons:
Historical manufacturing norms – Countries developed bedding and frame standards independently.
Regional sleeping preferences – For example, many European markets favor longer beds to accommodate taller statures.
Metric vs. imperial systems – Converting between centimeters and inches can create non-exact matches.
Cultural living styles – Smaller urban apartments in certain regions influence typical bed sizes.
For estate owners managing properties across continents, these differences can lead to mismatched linens, ill-fitting frames, and shipping delays.
United States Bed Size Standards
The US follows an imperial measurement system, and its beds are generally wider than their European equivalents.
Bed Size | Dimensions (inches) | Dimensions (cm) | Notes |
Twin | 38 x 75 | 96.5 x 190.5 | Common in guest rooms and children’s bedrooms. |
Twin XL | 38 x 80 | 96.5 x 203 | Popular in college dorms; longer than a standard twin. |
Full/Double | 54 x 75 | 137 x 190.5 | Traditional for single sleepers or smaller bedrooms. |
Queen | 60 x 80 | 152.5 x 203 | Most popular size for couples in the US. |
King | 76 x 80 | 193 x 203 | Wide and spacious, ideal for large rooms. |
California King | 72 x 84 | 183 x 213.5 | Narrower but longer than a standard king; good for tall sleepers. |
Key note for estates: US sizes are often larger than their UK or EU counterparts, so importing a US mattress for use in Europe may require custom bed frames.
United Kingdom Bed Size Standards
The UK also uses imperial measurements but has its own sizing rules.
Bed Size | Dimensions (inches) | Dimensions (cm) | Notes |
Single | 36 x 75 | 91 x 190 | Equivalent to a narrow twin in the US. |
Double | 54 x 75 | 137 x 190 | Matches US full in size. |
King | 60 x 78 | 152 x 198 | Shorter than a US queen in length. |
Super King | 72 x 78 | 183 x 198 | Similar width to a US California King but shorter in length. |
Key note for estates: The UK’s “King” is shorter than both the US Queen and King, which can cause sheet size compatibility issues.
European Union Bed Size Standards
Europe’s metric system means dimensions are given in centimeters, and lengths tend to run longer.
Bed Size (Common EU) | Dimensions (cm) | Dimensions (inches) | Notes |
Single | 90 x 200 | 35.4 x 78.7 | Longer than US or UK singles. |
Double | 140 x 200 | 55.1 x 78.7 | Wider than UK double but shorter than US queen. |
King | 160 x 200 | 63 x 78.7 | Popular couple’s size across Europe. |
Grand King | 180 x 200 | 70.9 x 78.7 | Similar width to US king but shorter in length. |
Key note for estates: If you have tall guests, EU mattresses often suit them better due to standard 200 cm length.
Middle Eastern Bed Size Standards
Middle Eastern mattress dimensions can vary widely depending on country, local manufacturing, and whether the product is imported.
Common Sizes in Gulf Countries:
Bed Size | Dimensions (cm) | Dimensions (inches) | Notes |
Single | 90 x 190 | 35.4 x 74.8 | Often shorter than EU singles. |
Double | 135 x 190 | 53.1 x 74.8 | Close to UK double size. |
Queen | 150 x 200 | 59 x 78.7 | Slightly narrower than US queen. |
King | 180 x 200 | 70.9 x 78.7 | Matches EU Grand King dimensions. |
Key note for estates: Many luxury hotels in the Middle East import European sizes for their consistency and length, making EU-style bedding common in high-end properties.
Challenges in Mixing Bed Sizes Across Borders
Bedding Incompatibility – Fitted sheets rarely work well across regions without tailored adjustments.
Shipping Delays – Custom sizing may require special orders that take weeks or months.
Frame Fit Issues – Even slight size differences can prevent a mattress from sitting securely.
Resale & Replacement – Harder to replace non-standard sizes locally.
How to Choose the Right Mattress Size for International Estates
Standardize per Property
Keep all beds in a property to one regional standard to simplify replacements.
Plan Bedding Procurement
If importing mattresses, import bedding in the same shipment to avoid compatibility issues.
Consider Guests’ Comfort
Taller beds (200 cm length or more) are ideal for diverse guests.
Work with Custom Manufacturers
Some high-end mattress brands can produce hybrid sizes blending two standards.
Practical Conversion Guide
Quick Reference:
US Queen ≈ UK King (shorter)
US King ≈ EU Grand King (shorter)
Middle Eastern King ≈ EU Grand King
EU Double is between a US Full and Queen in size.
A laminated chart in the estate’s household manual can help staff make fast bedding decisions.
In global estate management, small details create the biggest impressions. Guests notice when a bed feels cramped or sheets are ill-fitting. By mastering international mattress sizes, estate owners and hospitality managers can ensure every property delivers consistent comfort—no matter the continent. The key is preparation: know the standards, plan procurement accordingly, and work with suppliers experienced in cross-border furnishing.
