What is a Double Bed?

Double beds, also known as full mattresses, have been a common bed size for many years. In fact, before the 1950s and the introduction of queen and king size beds, many couples slept on a double bed, hence the name “double.”

Although manufacturers now offer more spacious mattress sizes, doubles are still a popular choice for many Americans. But what is a double bed and who is it right for? We answer these questions and explain the room dimensions needed for a double bed and the approximate cost. Read on to find out if this mattress size is right for you.

Dimensions of a Double Bed

Double beds are 54 inches wide—4 feet and 6 inches. Although this width is too narrow for most couples, it works well for a single sleeper.

The length of a double bed is 75 inches—6 feet and 3 inches. This size provides plenty of legroom for most sleepers. However, those over 6 feet tall may wake up with their feet dangling off the end of the bed.

The thickness of a double bed will vary depending on the type of mattress you purchase. Most memory foam beds are between 10 and 12 inches thick, while hybrid mattresses are between 12 and 14 inches thick.

Although the terms “double bed” and “full size bed” are often used interchangeably, both refer to a bed with the same dimensions—54 inches wide by 75 inches long. These measurements will apply to mattresses and bed frames labeled as “double” or “full.”

As you shop, you may come across mattresses and bed frames labeled at “full XL.” A full XL bed has the same width as a standard full mattress—54 inches. However, a full XL is 5 inches longer than a standard double bed, making it a good choice for those over 6 feet tall. Although full XL beds are less common, some mattress retailers offer this size.

Room Dimensions for a Double Bed

While queen and king size mattresses require a larger bedroom, double beds are more versatile and can fit comfortably in most spaces. If you live in a studio apartment or have a small bedroom, a double bed is a great way to maximize your space and still have one of the most comfortable mattresses.

A double bed can fit well in most bedrooms, including those with limited space. To leave a walking path around the bed and to account for any bedroom furniture, we suggest using a double bed in a room that measures at least 9 feet by 9.6 feet.

Considering the average bedroom size in the United States is 11 feet by 12 feet (132 square feet), double beds should fit well into most bedrooms.

Who are Double Beds Right For?

Since double beds measure 54 inches wide, this provides only 27 inches of space on each side of the bed. Therefore, most couples find a double bed too confining. However, doubles are the best mattresses for teenagers and single adult sleepers, guest rooms, and smaller apartments.

1. Children and Teens

Twin and full size mattresses are often the go-to options for children. However, twin beds, also known as a “single bed,” can start to feel too small as children grow and require more space to move around and get comfortable. This is especially true for tall sleepers who need more legroom.

A double bed is also small enough to fit inside most children’s rooms and still leave room for a play area or other furniture.

2. Single Adults

With a 54 inch width, double beds provide plenty of room for a single adult sleeper to spread out. Plus, double beds are versatile, easy to move, affordable, and fit well in most rooms without dominating the space.

For adult sleepers who are 6 feet or taller, we suggest opting for a full XL or queen size bed, both of which measure 80 inches long.

3. Guest Rooms

A double bed is a popular choice for guest bedrooms due to its ideal blend of comfort, space efficiency, and affordability. Since most guest rooms tend to be smaller or multifunctional spaces—often doubling as home offices, hobby rooms, or storage areas—a double bed provides ample sleeping surface without overwhelming the room. 

It can comfortably accommodate a solo adult or even a couple for short stays, making it a versatile option for hosting friends, family, or out-of-town visitors. Additionally, double beds are easy to dress up with stylish bedding to give the space a welcoming, hotel-like atmosphere. 

Because of its manageable size, a double bed allows for additional furniture—like nightstands, dressers, or a desk—without cramping the space. Whether you’re outfitting a dedicated guest room or just want to ensure visitors sleep well in a multipurpose space, a double bed offers the perfect middle ground between comfort and practicality.

4. Smaller Apartment

For those living in studio apartments, tiny homes, or compact urban spaces, a double bed is an excellent sleep solution. It strikes a careful balance between comfort and space-saving, providing solo sleepers with more room than a twin bed while still fitting into smaller floor plans. 

In tight quarters where every inch counts, a queen or king bed can quickly dominate the space, leaving little room for other essentials like a couch, desk, or storage unit. A double bed, on the other hand, offers enough room to stretch out without sacrificing the flow or functionality of the room. 

Its size also makes it easier to move and reposition, which is ideal for renters or those who frequently rearrange their living spaces. If you’re trying to maximize living space in a small apartment while still prioritizing sleep comfort, a double bed can be the ideal solution.

5. Budget-Conscious Shoppers

For those who want comfort without breaking the bank, a double bed presents a cost-effective alternative to larger mattress sizes. Both mattress and bedding accessories like sheets, blankets, and bed frames tend to be more affordable than their queen or king counterparts. 

This makes it an excellent choice for furnishing a room on a budget—whether it’s for a rental property, a child’s transition bed, or a short-term living situation. Its compact size also reduces the need for larger, more expensive room furnishings and allows you to shop smart without sacrificing sleep quality.

Price of a Double Bed

Double mattresses are more affordable than queen and king size beds. Plus, mattress accessories, such as bed frames, adjustable beds, foundations, mattress protectors, comforters, pillows, and sheets, are less expensive when shopping for a double bed.

A high-quality double mattress typically costs between $200 and $1500. Memory foam mattresses and hybrid beds tend to cost between $800 and $1500 for a double size. Innerspring beds are often less expensive but will not last as long as those with a thick foam comfort layer.

Factors to Consider When Choosing a Double Bed

When shopping for a double bed, it’s essential to look beyond the size and consider how the bed will function in your space and support your comfort. 

1. Number Of Sleepers

One of the first factors to evaluate is the number of sleepers using the bed. While a double bed can technically fit two people, it’s best suited for solo sleepers, teenagers, or guest use. Couples often find a double bed too narrow, especially if either partner tends to move during the night. 

With only 27 inches of sleeping width per person, it can feel cramped over time. For occasional use in a guest bedroom or a teen’s room, however, the size is ideal—it offers a step up in comfort from a twin without taking up as much space as a queen.

2. Sleeping Style And Comfort Needs

Your sleeping style and comfort needs also play a major role in determining the best double bed for you. Side sleepers may benefit from softer mattresses that cushion pressure points at the shoulders and hips, while back and stomach sleepers typically need firmer support to maintain proper spinal alignment. 

If you’re a hot sleeper, look for breathable mattress materials like latex or gel-infused memory foam. It’s also important to consider motion isolation if you plan to share the bed—even occasionally—as smaller mattresses tend to transfer more movement than larger ones.

3. Storage Needs

If you’re short on space or live in a smaller home, your storage needs should guide your decision as well. Double beds with integrated storage—such as drawers underneath, lift-up platforms, or built-in shelves in the headboard—can significantly reduce the need for extra furniture like dressers or storage bins. These options are particularly helpful in apartments, dorm rooms, or multi-use guest rooms where maximizing floor space is a priority.

4. Budget

Your budget will also influence your choice. Double beds are generally more affordable than queen or king-sized beds, making them a practical choice for first-time buyers, students, or people furnishing a guest room. 

However, prices vary widely depending on the quality of the frame, mattress type, and additional features like storage or adjustability. It’s wise to plan for the total cost, including not just the bed frame and mattress, but also pillows, sheets, and bedding accessories. 

While it’s tempting to go for the cheapest option, investing in a high-quality mattress can make a noticeable difference in your sleep quality and overall satisfaction.

5. Design And Aesthetics

Don’t overlook the importance of design and aesthetics, especially if the bed will be the focal point of your bedroom. Whether you prefer a rustic wooden frame, a sleek upholstered headboard, or a modern metal design, your choice of materials and finishes should complement your existing decor. 

Platform beds offer a low-profile, minimalist look, while a bed with an ornate headboard can add a touch of elegance. Choosing a style that reflects your personal taste will help create a cohesive and visually pleasing sleep environment.

6. Additional Features or Functions

You should also consider whether you want any additional features or smart functionalities in your bed. Adjustable double beds, for example, allow you to elevate the head or foot of the mattress, which can be beneficial for conditions like acid reflux, snoring, or back pain. 

Other beds come with USB ports, built-in lights, or even massage functions for added luxury. If you live in a studio or need a dual-purpose piece, a sofa-cum-bed or Murphy bed might be the perfect multifunctional solution. These innovations not only save space but also offer greater versatility for modern living.

7. Ease Of Delivery And Assembly

Another practical factor is the ease of delivery and assembly. Consider whether the bed can be transported easily through doorways, staircases, or elevators—especially important for apartment dwellers. 

Some beds come in flat-pack boxes and require self-assembly, while others may need professional help. Be sure to check whether the retailer offers white-glove delivery or in-home setup services, especially if you’re purchasing a heavy wooden or storage bed.

8. Durability And Warranty

Finally, don’t forget to evaluate the durability and warranty. A sturdy frame made of hardwood or reinforced metal will last much longer and support your mattress better than cheaper alternatives. 

Also, be sure to review the warranty terms on both the mattress and bed frame—look for at least 5 to 10 years of coverage. Reading customer reviews can also give insight into how well a particular bed holds up over time, especially if it will be used frequently.

Types of Double Beds

1. Standard Double Bed (Full Bed)

The standard double bed—often referred to interchangeably as a full bed—is the classic and most widely recognized version of this size. Measuring 54 inches wide by 75 inches long, it offers significantly more room than a twin bed but is more compact than a queen. 

This makes it an excellent fit for single sleepers who like to sprawl out or want extra space for pillows and blankets. Though it’s traditionally been used for couples, modern sleeping preferences have shifted toward larger sizes like queen or king for shared sleeping. 

Still, a standard double bed is an economical, space-saving option that fits well in medium-sized bedrooms, studios, or shared living spaces. It’s also widely available in various mattress types—memory foam, innerspring, hybrid, and latex—making it highly customizable to different comfort preferences and budgets.

2. Double Bed with Storage

A double bed with storage is ideal for maximizing space in smaller rooms or minimalist interiors. These beds are ingeniously designed with built-in storage compartments, which may include drawers underneath the frame, a lift-up hydraulic base, or headboards with hidden shelves. 

These options help eliminate the need for separate dressers or storage bins, freeing up floor space for other essentials. Storage double beds are particularly popular in urban apartments, children’s bedrooms, or homes where every square foot counts. 

They’re perfect for storing seasonal bedding, clothing, shoes, or even books and electronics, depending on the design. With these beds, functionality meets style, and many modern options come with upholstered frames and sleek, contemporary finishes.

3. Platform Double Bed

A platform double bed offers a sleek, low-profile design that fits well in modern and minimalist bedroom aesthetics. It consists of a sturdy base—either solid or slatted—that supports a mattress without the need for a box spring or foundation. These beds typically sit lower to the ground, which can make a room feel more open and spacious. 

Platform beds are available in a wide range of materials including wood, metal, or upholstered frames, often with built-in headboards or optional storage features. They’re also known for being more affordable since they eliminate the cost of a box spring. 

This type of double bed appeals to those who prefer a clean, uncluttered look while still enjoying solid mattress support and long-term durability.

4. Double Divan Bed

A divan bed is a traditional and elegant type of double bed that combines a sturdy upholstered base with a comfortable mattress. What sets it apart is the optional built-in drawer storage, typically found at the base, which makes it both practical and stylish. Divan beds often come in modular sections, making them easy to move, assemble, and customize with different headboards and fabric finishes. 

They’re commonly used in hotels due to their luxurious comfort and smart space-saving design. Some high-end divan beds even feature orthopedic or pocket-sprung bases for enhanced support. A double divan bed is ideal for people who want both comfort and functionality in a classic, tailored format.

5. Double Bunk Bed (Full-Over-Full)

A double bunk bed, or full-over-full bunk, is a space-saving solution that stacks two double-sized beds vertically. This design is perfect for shared bedrooms in family homes, vacation rentals, or sleepover-friendly spaces. Each level measures 54″ x 75″, giving significantly more room than traditional twin bunks and making them suitable for teenagers, adults, or multiple children. 

Most double bunk beds feature a sturdy ladder, safety rails, and durable frames made of metal or wood. Some models even offer trundle beds or built-in storage. 

They’re especially useful in homes with limited floor space but a need for multiple sleeping arrangements. While functional, they can also be styled with themed bedding or canopies for a fun, cozy sleeping experience.

6. Folding or Murphy Double Bed

A Murphy bed, also known as a wall bed or pull-down bed, is a clever, foldable sleeping solution that tucks vertically into a cabinet or closet when not in use. When designed in double size, it offers all the comfort of a standard bed while saving enormous floor space during the day. 

Murphy double beds are ideal for small homes, studio apartments, or home offices that occasionally double as guest rooms. Many come with built-in shelves or desks on the front-facing side, adding further functionality. 

Newer designs often feature gas pistons or counterbalanced springs for easy lifting and lowering. If you’re looking to combine comfort, convenience, and style in a multifunctional space, a Murphy double bed is hard to beat.

7. Sofa Cum Double Bed (Sleeper Sofa)

A sleeper sofa or sofa cum double bed is a multi-functional furniture piece that serves as both a couch and a bed, making it perfect for apartments, guest rooms, or rooms that serve dual purposes. During the day, it acts as a comfortable seating area, and at night, it converts into a double bed using a pull-out mechanism or a fold-down backrest. 

Available in styles ranging from minimalist futons to plush sectionals, sleeper sofas are a practical choice for those who need occasional sleeping space without sacrificing living room utility. While the mattress quality may not match that of a traditional bed, many modern sleeper sofas now include memory foam or hybrid mattresses for improved comfort.

8. Canopy Double Bed

A canopy double bed features four tall posts connected by rods at the top, often draped with fabric, curtains, or netting for an elegant and enclosed feel. While traditionally associated with vintage or Victorian interiors, modern canopy beds come in streamlined, minimalist designs using metal or wood for a more contemporary look. 

A double-size canopy bed can be an eye-catching centerpiece in a small bedroom, offering both visual interest and a cozy, enclosed sleeping space. Some people enjoy the added privacy or the ability to block out light and drafts with curtain panels. 

Canopy beds also allow for creative customization through the choice of drapes, string lights, or decorative elements.

9. Adjustable Double Bed

An adjustable double bed is a technologically enhanced sleeping system that lets you raise or lower the head and/or foot of the mattress for customized comfort. While they’re more commonly available in larger sizes like queen or king, some manufacturers offer double-size adjustable beds for individuals with specific health conditions or comfort needs. 

These beds can help alleviate symptoms of acid reflux, sleep apnea, snoring, back pain, and poor circulation. They often come with remote controls, massage functions, and even USB ports. 

Adjustable double beds are particularly beneficial for elderly individuals or people recovering from surgery, allowing for easier movement in and out of bed and better overall support.

Pros and Cons of a Double Bed

Pros of a Double Bed

• More Spacious Than a Twin: A double bed is significantly wider than a twin (by 15 inches), giving solo sleepers ample room to spread out and sleep comfortably. It’s great for people who like to shift positions or sprawl out during the night.
• Compact Size: Measuring 54” x 75”, a double bed fits well in small to medium-sized bedrooms, guest rooms, studio apartments, or shared spaces. It allows for additional furniture like nightstands, wardrobes, or desks without making the room feel cramped.
• Budget-Friendly Option: Double beds are usually more affordable than queen or king-sized options—not just the mattress, but also the bed frame, headboard, and bedding. This makes them ideal for students, first-time renters, or budget-conscious shoppers furnishing a home.
• Widely Available Accessories: Bedding for double beds is widely manufactured and sold in a variety of styles, materials, and price points. From high-thread-count sheets to stylish comforters and mattress protectors, finding accessories is easy and often inexpensive.
• Lighter and Easier to Move: Due to their smaller size and weight, double beds are easier to maneuver during moves, furniture rearrangements, or room cleaning. They’re ideal for people who relocate frequently or live in walk-up apartments.
• Great for Teens and Young Adults: A double bed is the perfect size for teenagers or young adults who have outgrown their childhood twin beds but don’t need or have room for a queen.
• Energy Efficient in Climate-Controlled Rooms: Since it requires less bedding and heating or cooling, a double bed is more energy-efficient, which can help reduce utility bills, especially in small, temperature-controlled bedrooms.

Cons of a Double Bed

• Too Small for Most Couples: With just 27 inches of width per person, a double bed can feel cramped for two adults, especially if one is a restless sleeper or if either person is larger in size. It’s generally not recommended as a long-term solution for couples.
• Shorter Length May Not Suit Taller Individuals: At only 75 inches (6 feet 3 inches) long, double beds may be too short for people over 6 feet tall. Taller sleepers may find their feet hanging off the edge, which can lead to discomfort and poor sleep posture.
• Limited Versatility for Pets or Co-Sleeping with Children: If you share your bed with a pet or small child, a double bed may feel cramped. There’s not much room to accommodate extra bodies without compromising sleep quality.
• Less Common in Luxury Settings: Double beds are generally considered basic or utilitarian, so they’re less commonly found in high-end hotels or luxury home designs. If aesthetics and status matter, you might find the double size too simple or outdated.
• Reduced Edge Support in Some Mattresses: Due to the smaller surface area, cheaper double mattresses may have weaker edge support compared to their queen or king counterparts, making the bed feel less stable near the sides.
• Not Ideal for Active Sleepers: People who toss and turn throughout the night might feel restricted on a double bed. If you need space to move around freely while you sleep, you may outgrow this size quickly.
• May Require Frequent Upgrades: While a double bed may be ideal in the short term, many users eventually upgrade to a queen or larger. That can make a double bed feel like a temporary solution, especially if life circumstances (e.g., relationships, pets, or moving) change.

Different Double Bed Mattresses

How Double Beds Compare to Other Standard Mattress Sizes?

The six standard bed sizes in the United States are twin, twin XL, full (double), queen, king, and California king. Below, we explain how a double bed compares to these common sizes.

Twin and Twin XL Size Mattresses

A twin mattresses measures 38 inches wide and 75 inches long. These beds are the same length as a standard double/full size mattress. A twin XL size mattress is the same width as both a standard twin and double mattress; however, twin XL mattresses are 5 inches longer, making them 80 inches long, the same as a full XL mattress.

Queen Size Mattresses

Queen mattresses measure 60 inches wide and 80 inches long—6 inches wider and 5 inches longer than a double bed. Queen beds are the most popular size in the US because they are large enough to accommodate two sleepers with 30 inches of space on each side of the bed.

King Size Mattress

King size mattresses measure 76 inches wide by 80 inches long. This size is 22 inches wider and 5 inches longer than a standard double bed. King size beds are ideal for couples who prefer more personal space or for families who prefer co-sleeping.

California King Size Mattress

California king size mattresses are 4 inches longer and 4 inches narrower than a standard king size bed—72 inches wide by 84 inches long. This size variation is a good option for couples who are over 6 feet tall.

Cal kings are 18 inches wider and 9 inches longer than a double size bed.

Frequently Asked Questions

Can I put queen sheets on a full bed?

No. Queen beds are 6 inches wider and 5 inches longer than a full bed. Therefore, sheets made to fit a queen bed will be too big to fit snugly on a full size bed. Using queen sheets on a full bed will likely cause the sheets to move and bunch up during sleep.

Do two twin beds make a queen?

No. twin beds measure 38 inches wide by 75 inches long. Two twin beds placed side by side will not make a standard queen size bed, which measures 60 inches wide by 80 inches long. However, two twin XL beds, which each measure 38 inches wide by 80 inches long, will create a standard king size bed (76 inches wide by 80 inches long) when placed side by side.

What size bed do most couples sleep on?

In most cases, queens make the best mattresses for couples. A queen size bed has 30 inches of personal space on each side of the bed, allowing each person enough room to stretch out. Taller couples or familiar who prefer to co-sleep may be more comfortable on a king size bed, which measures 76 inches wide by 80 inches long.

How much smaller is a double bed than a queen?

Double beds measure 54 inches wide by 75 inches long, while queen size beds measure 60 inches wide by 80. Therefore, a queen is 6 inches wider and 5 inches longer than a double bed. Queen size mattresses work well for most couples, while double beds are ideal for growing children, teens, and single adult sleepers less than 6 feet tall.

What size bed do I need for a 10 by 10 room?

A double bed will fit comfortably in a 10 by 10 room. However, if you opt for a full XL size mattress, it may feel too confined in a 10 by 10 room. If you prefer a bed larger than a double bed, your bedroom should measure at least 11 by 12 feet.

Conclusion

Even if you are resting on a comfortable mattress, you may not get a good night’s sleep if it is too small. Although a double bed may not work for most couples, single adult sleepers and teens will enjoy the extra space of a double bed. Plus, doubles are more affordable, easily accessible, and fit well into most spaces.
