Full Size Mattresses
A Full size mattress measures 53 inches wide by 75 inches long, which is the same length as a standard Twin, but 15 inches wider. That extra width is the whole story. It gives solo sleepers more room to stretch out, makes a guest room feel thoughtfully outfitted, and offers couples a budget-conscious option when a Queen is more than the space allows. Every Leesa Full is built with the same premium materials and craftsmanship as every size we make. Choose from hybrid innerspring designs or memory foam. All backed by a 120-night trial, free shipping, and a limited lifetime warranty.

Full Size Mattress Dimensions — What You Need to Know
A Full size mattress is 53 inches wide by 75 inches long (4’5” x 6’3”). It is also called a double bed; the terms are interchangeable and refer to exactly the same size. The Full is 15 inches wider than a Twin or Twin XL but shares the same 75-inch length. It is shorter than a Queen, which runs 80 inches long.

Full vs. Queen vs. Twin - Which Size Is Right for You?
Most people comparing a Full are deciding between a Full and a Queen, or reconsidering a Twin they have outgrown. Here is how those comparisons break down.
Full vs. Queen
A Queen is 60 inches wide by 80 inches long—7 inches wider and 5 inches longer than a Full. For most solo adults and most couples, a Queen is the more comfortable long-term choice if the room fits it. A Full makes sense when square footage is genuinely limited, when budget is a factor, or when you are buying for a guest room that sees occasional use. If you are on the fence and the room can accommodate a Queen, the Queen is generally worth it.
Full vs. Twin
A Full is 15 inches wider than a Twin at the same 75-inch length. For an adult who has outgrown a Twin and wants more room to move around during sleep, a Full is the natural upgrade. The Twin remains the right size for kids, bunk beds, and very small rooms where every inch counts. For solo adults in a studio or first apartment who need a proper sleeping surface, the Full is typically where to start.
Full vs. Twin XL
A Twin XL is 38 inches wide by 80 inches long—narrower than a Full but 5 inches longer. For tall sleepers who prioritize length over width, or who are furnishing a college dorm, Twin XL is the better fit. For solo adults who move around during sleep and are of average height, the Full offers more lateral room. These two sizes rarely compete directly; the deciding factor is usually height versus width preference.
Still deciding? Our Compare Mattresses tool and Mattress Quiz can help you find the right fit.
Who Is a Full Size Mattress Best For?
A Full is a deliberate choice, not a default. Here is who it suits best.
Solo Adults Upgrading from a Twin
A Full is the most common first upgrade for adults who have outgrown a Twin. The extra 15 inches of width makes a meaningful difference for sleep comfort without requiring the footprint of a Queen. For anyone setting up a first bedroom on a budget, or in a space that does not comfortably fit a Queen, a Full is the practical starting point.
Couples in Smaller Rooms
A Full can sleep two adults, but it is worth being honest about the tradeoff: 53 inches of shared width gives each person roughly 26 inches of sleeping space—similar to a crib. For occasional or short-term use, that works. For a primary bed shared nightly by two adults, a Queen or King will be significantly more comfortable for both sleepers. If you are furnishing a couple's primary bedroom and the room fits a Queen, the Queen is the better investment.
Guest Rooms
A Full is an excellent guest room mattress. It fits one guest comfortably and two guests in a pinch, keeps the room from feeling dominated by the bed, and leaves space for other furniture. For guest rooms that see occasional use, a Full strikes the right balance between hospitality and practicality.
Smaller Bedrooms and Apartments
When a Queen is too wide for the room layout—leaving insufficient clearance on the sides—a Full is the right answer. It fits comfortably in rooms as small as 9 x 10 feet while still leaving walkable space around the bed. For apartments where the bedroom doubles as a living space, the reduced footprint of a Full is often the deciding factor.

How does the 120-night sleep trial work?
Every Leesa mattress comes with a 120-night trial. After 30 days of sleeping on your new mattress, if you're not happy with your purchase, the friendly folks on our Comfort Crew can help walk you through the process of returning and refunding.
Whenever possible, we donate any returned mattresses to a 501(c)(3) organization or one of our charity partners. One of Leesa's missions is to be a positive force in the world, so if we can donate a mattress in good condition rather than disposing of it in a landfill, that's the route we're going to take.

Is a Full mattress the same as a double bed?
Yes. Full and double are two names for exactly the same mattress size: 53 inches wide by 75 inches long. The term “double” is older and less commonly used today, but you will still see it used by some retailers and frame manufacturers. If you are buying a frame labeled “double,” it will fit a Full size mattress.
What is the difference between a Full and a Queen mattress?
A Queen is 60 inches wide by 80 inches long. A Full is 53 inches wide by 75 inches long. That means a Queen is 7 inches wider and 5 inches longer. For most adults and most couples, a Queen provides meaningfully more sleeping surface. A Full is the right choice when room dimensions are the constraint, budget is a factor, or the mattress is for a guest room rather than a primary bed.
Can a Full mattress fit two people?
A Full can sleep two adults, but it is a tight fit. With 53 inches of shared width, each person has roughly 26 inches of space—comparable to a crib. For occasional use or for couples who sleep close together, a Full works. For a couple's primary bed used nightly, a Queen or King will be significantly more comfortable. If you are shopping for two regular sleepers and the room allows it, we recommend sizing up.
What is the difference between a Full and a Twin mattress?
A Full is 53 inches wide; a Twin is 38 inches wide—a difference of 15 inches. Both are 75 inches long. A Twin suits one person in a smaller space or a child's room. A Full is the standard first upgrade for adults who want more room to move around during sleep without the footprint of a Queen. If you are an adult who has been sleeping on a Twin, a Full is the most direct step up.
Is a Full mattress good for a guest room?
Yes. A Full is one of the most practical choices for a guest room. It fits one guest comfortably and two guests adequately for a short stay. It keeps the room from feeling dominated by the bed and leaves space for other furniture. For guest rooms that see occasional rather than regular use, a Full provides genuine comfort without requiring a Queen footprint.
What size bed frame do I need for a Full mattress?
A Full mattress requires a frame with an interior sleeping surface of approximately 53 inches wide by 75 inches long. Most Full and double-labeled bed frames, platform beds, and daybeds are built to these dimensions. When buying a frame, confirm the interior measurements rather than the overall frame dimensions, which are typically a few inches larger on each side. Leesa's platform bed frames are available in Full size.
What are the exact dimensions of a Full size mattress?
A Full size mattress is 53 inches wide by 75 inches long (4 feet 5 inches by 6 feet 3 inches), or approximately 134.6 cm x 190.5 cm. Mattress height varies by model. Leesa Full mattresses range from approximately 10 to 13 inches in height depending on the model. Height affects clearance for under-bed storage and compatibility with low-profile frames. See our sizes & weights support article for more information.
Is a Full mattress good for taller people?
A Full is 75 inches long—the same length as a Twin. For anyone over 6 feet 3 inches, that length may feel restrictive. Taller sleepers who need extra length should consider a Twin XL or Queen, both of which are 80 inches long. A Full is well-suited to sleepers up to approximately 6 feet tall who prioritize width over length.
How much does a Full size mattress cost?
Leesa Full size mattresses are available at a range of price points depending on construction and features. Every model ships free and comes with a 120-night trial and a limited lifetime warranty. Visit the individual product pages for current pricing.
Should I choose a memory foam or hybrid Full size mattress?
Memory foam models conform closely to the body and are good for pressure relief and motion isolation — a strong choice for solo sleepers or light co-sleepers who are sensitive to movement. Hybrid models combine foam layers with a coil support system for a more responsive feel with better airflow. For couples sharing a Full, a hybrid's motion isolation and edge support can make the tight sleeping surface feel more manageable. The Mattress Quiz can help identify the right construction for how you sleep.
