Full XL Bed And Mattress Dimensions(Size, Height, Length & Width)

Find exact Full XL bed dimensions, how they compare to standard Full, Queen, and Twin XL sizes.We’ll cover everything from room size requirements and where to find Full XL sheets and bed frames to pricing, pros and cons, each thing you need to know.

What Are the Exact Full XL Bed Dimensions?

Standard Full XL Mattress Measurements (Inches & Centimeters)

The Full XL mattress dimensions are 54 inches wide and 80 inches long. In centimeters, that’s 137 cm × 203 cm. This makes it 5 inches longer than a regular Full bed, which measures 54″ × 75″.

Full XL beds provide 30 square feet of sleeping surface. That’s 4,320 square inches of space for one sleeper. The extra length matches the same 80-inch measurement found in Queen, King, and Twin XL mattresses.

Full XL Surface Area and Thickness

A Full XL bed offers 4,320 square inches of total sleeping space. That’s about 1.7 square feet more than a standard Full mattress, giving taller sleepers crucial extra legroom.

Mattress thickness typically ranges from 8 to 14 inches for Full XL beds. Memory foam models tend to be 10-12 inches thick, while innerspring and hybrid options often measure 12-14 inches. Thicker mattresses provide more cushioning and support layers.

The bed height depends on your foundation choice. A platform bed adds 5-8 inches, while a box spring foundation adds 9-12 inches to the total height.

Full XL vs. Other Mattress Sizes

Full XL vs. Standard Full Size Bed

A standard Full mattress measures 54″ × 75″, while a Full XL is 54″ × 80″. The width stays exactly the same—only the length changes. That extra 5 inches makes a huge difference for tall sleepers over 6’2″.

Both sizes work great for single adults in smaller bedrooms. But if your feet hang off a regular Full, the Full XL solves that problem instantly. The width gives you 54 inches of personal space, which is comfortable for one person.

Price difference between the two is minimal—usually $50-100 more for Full XL.

Full XL vs. Queen Mattress Dimensions

A Queen bed measures 60″ × 80″—that’s 6 inches wider than a Full XL but the same 80-inch length. Both mattresses accommodate tall individuals equally well with that extended length.

The Queen provides 30 inches of width per person if sharing, while a Full XL gives you all 54 inches to yourself. For couples, Queens are the better choice. For single sleepers in tight spaces, Full XL maximizes length without excess width.

Queens fit standard 10′ × 10′ bedrooms comfortably. Full XL beds work in 9.5′ × 10.5′ rooms, saving you about 6 inches of floor space. That difference matters in small apartments and dorm rooms.

King Bed Size and mattress Dimensions(Size, Height, Length & Width)

Full XL vs. Twin XL Size Comparison

Twin XL beds measure 38″ × 80″—matching the Full XL’s 80-inch length but 16 inches narrower. Both sizes target taller sleepers who need that extra legroom beyond standard 75-inch mattresses.

A Full XL gives you 42% more sleeping width than a Twin XL. That’s the difference between feeling cramped and sleeping comfortably. Twin XLs work for college dorms and bunk beds, while Full XL suits single adults better.

Two Twin XL mattresses pushed together equal a King bed (76″ × 80″), not a Full XL. The Full XL stays narrower than most couple-sized beds, making it ideal for guest rooms and studio apartments.

Who Should Buy a Full XL Mattress?

Ideal for Tall Single Sleepers (Over 6 Feet)

Anyone taller than 6 feet needs at least 80 inches of mattress length. A Full XL delivers that without the extra width of a Queen.

Single adults between 6’0″ and 6’6″ find Full XL beds perfect. You get comfortable sleeping space without overwhelming a smaller bedroom.

Perfect for College Dorms and Small Apartments

Dorm rooms average 130-150 square feet—barely enough space for a desk and bed. A Full XL fits these tight quarters better than a Queen while still accommodating tall students.

Studio apartments and efficiency units benefit from Full XL beds too. You save 6 inches of width compared to a Queen, which opens up floor space for other furniture. That matters when every square foot counts.

The vertical sleeping space works great for taller college students who need a step up from standard Twin XL dorm beds.

Great Guest Room Solution

Guest bedrooms typically run 10′ × 10′ or smaller. A Full XL accommodates tall overnight visitors without dominating the room.

Visiting family members over 6 feet tall appreciate the extra legroom.

Full XL Bed Room Size Requirements

Minimum Bedroom Dimensions for Full XL Beds

A 9.5′ × 10.5′ bedroom provides the minimum space for a Full XL bed. This leaves 24-30 inches of walking space on each side—enough to move around comfortably.

Ideally, plan for a 10′ × 11′ room or larger. This gives you space for nightstands and a small dresser. Anything smaller than 9.5′ × 10′ makes the room feel too cramped.

Measure your room before buying. Mark out the 54″ × 80″ footprint with painter’s tape on the floor. Walk around it to test if you have enough clearance space.

Space Planning

Leave 24 inches minimum on each side of your Full XL bed for easy walking. This standard clearance allows you to make the bed and move around without bumping into walls.

Finding Full XL Bed Frames, Sheets, and Accessories

Full XL Bedding Compatibility

Regular Full sheets won’t fit a Full XL mattress. Standard Full fitted sheets measure 54″ × 75″, which leaves 5 inches of mattress exposed at the foot. You need sheets specifically labeled “Full XL” or “54 × 80.”

Full XL sheet sets are harder to find than standard sizes. Online retailers like Amazon and specialty bedding sites carry them. Expect to pay $30-80 for a decent quality sheet set.

Bed frames for Full XL require 54″ × 80″ dimensions. Standard Full frames (54″ × 75″) are too short.

Do Regular Full Sheets Fit Full XL Beds?

No, standard Full sheets don’t fit Full XL mattresses properly. The fitted sheet will be 5 inches too short, creating bunching and pulling issues. The sheet corners won’t reach the mattress bottom.

You must buy Full XL-specific sheets for proper fit. These match the 54″ × 80″ dimensions exactly.

Flat sheets from Full sets might work as flat sheets only. But fitted sheets absolutely must be Full XL size. Don’t try to make standard Full fitted sheets work—they’ll frustrate you nightly.
