What is Double Extra Long?

Double Extra Long refers to a specific size of bedding, particularly mattresses and bed linens.


Double Extra Long, often abbreviated as DXL, is a bedding size that caters to those who require a little extra length without the additional width found in larger sizes like Queen or King. This size is particularly beneficial for taller individuals who find standard double or full beds too short for comfortable sleeping. The Double Extra Long measures approximately 54 inches in width and 80 inches in length, providing an additional 5 inches in length compared to the standard double or full mattress.

Choosing the right bedding size is crucial for comfort, room layout, and overall aesthetics. DXL bedding is less common than standard sizes, so finding bed frames, linens, and comforters that fit perfectly might require a bit more effort. However, the extra length can significantly improve sleep quality for those who need it. This size is also an excellent choice for guest bedrooms, combining the economy of space with the luxury of extra length to accommodate various guest sizes.


In a bedroom furnished for a tall individual, a Double Extra Long bed would be chosen instead of a standard double bed to ensure the occupant could stretch out comfortably without their feet hanging off the edge. In interior design, selecting a DXL mattress could also influence the choice of other bedroom furniture, ensuring a cohesive and proportional room layout.


  • How does a Double Extra Long compare to a Queen size?

    A Double Extra Long is the same length as a Queen-size bed but is 6 inches narrower. The DXL is approximately 54 inches wide by 80 inches long, while a Queen measures about 60 inches wide by 80 inches long.

  • Is it difficult to find linens for a Double Extra Long bed?

    Finding linens for a Double Extra Long bed can be more challenging than for standard sizes, but many specialty bedding stores and online retailers offer options. It's important to search specifically for “Double Extra Long” or “DXL” bedding.

  • Can a Double Extra Long bed accommodate two people comfortably?

    A Double Extra Long bed can accommodate two people, similar to a standard double bed. However, it offers extra length, making it more comfortable for taller individuals.

Practical Application

When selecting a Double Extra Long bed, measure your room carefully to ensure it fits well in the space. Look for bedding labeled specifically as DXL to match the unique dimensions. Given the less common size, considering a custom or semi-custom bed frame might also be worthwhile to ensure a perfect fit and tailored look. For interior designers, suggesting a DXL bed can demonstrate thoughtful consideration of a client's personal comfort and room dynamics.
