Is There an Extra Long Full Size Bed? The Truth About XL Double Beds

When shopping for a new mattress, the standard full size dimensions of 54 inches wide by 75 inches long often leave taller individuals tossing and turning. If you find yourself stretching out at the foot of the bed or constantly curling your legs to fit, you are likely asking the essential question: is there an extra long full size bed.

Understanding the Extra Long Full Size Option

The short answer is yes, the extra long full size mattress exists to solve exactly this problem. While not as ubiquitous as the standard full, this specific size maintains the 54-inch width that couples or solo sleepers prefer but extends the length to 80 inches. This extra 5 inches compared to a standard full provides ample legroom and creates a sleeping surface that rivals the length of a standard king bed, making it a critical option for taller sleepers.

Dimensions and Comparisons

To truly grasp the benefit, it helps to compare the numbers. A standard full mattress sits at 75 inches, which is the length of a typical twin XL. However, the extra long version measures in at 80 inches, aligning perfectly with the length of a standard king mattress. Below is a quick breakdown of how this size stacks up.

Who Benefits Most from This Length?

Tall individuals are the obvious beneficiaries, but the value extends to couples of average height who simply desire extra luxury. If you are over 6 feet tall, sleeping on a 75-inch mattress often means your feet hit the board or the box spring, forcing your spine out of alignment. By choosing the extra long version, you allow your legs to fully extend, promoting better spinal health and reducing morning stiffness.

Compatibility with Bed Frames

Before purchasing, it is vital to verify that your current setup can accommodate the extra long full size. Because this size is less common, not every bed frame on the market is designed for it. You must specifically look for frames that list compatibility with 80-inch mattresses or "Extra Long Full." Standard full-size frames will usually have a leg or support structure positioned where the extra 5 inches will land, causing the mattress to buckle or slide.

The Advantages Over Splitting King Size

Some shoppers consider buying two twin XL or full-size mattresses to create a custom length. However, the extra long full size offers a distinct advantage over this approach. Because it is a single, unified mattress, there is no middle valley or gap where the two mattresses meet. This eliminates the annoying "ridge" that can disrupt sleep and allows you to keep the same sturdy base and frame, saving you the cost of purchasing an entirely second bed.

Finding the Right Fit for Your Bedroom

Another practical aspect to consider is room layout. A standard king bed requires a significant amount of space, often necessitating a large master bedroom to prevent the furniture from overwhelming the space. The extra long full size offers a middle ground; it provides the generous length of a king but maintains the narrower 54-inch width of a full. This makes it an ideal choice for narrower bedrooms or guest rooms where you want comfort without sacrificing floor space.

Mattress Type Availability

Gone are the days when the only option for an extra long full was a basic innerspring model. Modern manufacturing has expanded this size across all major mattress categories. Whether you prefer the contouring feel of memory foam, the responsive bounce of latex, or the classic support of hybrid coils, you can find an extra long full version. This ensures that taller sleepers do not have to compromise on their preferred comfort technology to get the length they need.

Final Considerations for Your Purchase

Deciding if the extra long full size is right for you comes down to two factors: your height and your room. If you are over 6 feet tall or share a bed with someone who is, the additional length can drastically improve sleep quality. However, you must measure your current setup. Verify that your frame, foundation, and headboard can accommodate an 80-inch mattress to ensure a smooth transition and a secure, stable sleeping surface for years to come.
