Mattress Size Chart

Twin Size (39″ x 75″)

Twin-size mattresses, measuring 39″ x 75″, are a versatile and practical choice for various spaces in your home. Perfectly suited for children’s rooms and guest bedrooms, these compact beds are also ideal for daybeds, bunk beds, trundle units, and hideaways. Their narrow width makes them easy to make and fit into almost any room layout.

With a width of 39 inches per person, twin-size mattresses offer a cozy yet comfortable sleeping solution for both kids and adults. Whether you’re furnishing a small bedroom or creating a multifunctional guest space, a twin-size mattress is the perfect blend of convenience and comfort.

Twin XL Size (39″ x 80″)

Twin Extra-Long mattresses, measuring 39″ x 80″, are a popular choice for college dorm rooms due to their extra length, which is 5 inches longer than a standard twin. This added length provides extra comfort for taller individuals while maintaining a narrow width of 39 inches per person.

Although bedding options for Twin XL sizes can be somewhat limited, their extended length and versatility make them an excellent choice for students and anyone needing a compact yet spacious sleeping solution. Ideal for maximizing comfort in small spaces, Twin XL mattresses are a practical and comfortable option for dorms and guest rooms alike.

Full Size, aka Double (54″ x 75″)

Full-size mattresses, also known as Double beds, measure 54″ x 75″ and are a great option for guest rooms or as a step-up mattress for growing children. Offering 15 inches more width than a twin bed, a full-size mattress provides extra space for a single sleeper. However, its length of 75 inches might be too short for some adults.

While it’s possible for two adults to share a full-size bed, each person would only have 27 inches of width, which is significantly less than the 39 inches provided by a twin bed. Despite this, a full-size mattress remains a popular choice for its balance of space and affordability, making it a versatile solution for various sleeping arrangements.

Full XL Size (54″ x 80″)

Full Extra-Long mattresses, measuring 54″ x 80″, are an excellent choice for solo sleepers or guest rooms. With an additional 5 inches in length compared to a standard full bed, Full XL mattresses provide extra comfort for taller individuals.

Despite their increased length, bedding options for Full XL sizes can be somewhat limited. Offering 54 inches of width, or 27 inches per person if shared, this mattress size strikes a balance between spaciousness and practicality. Ideal for those seeking a bit more legroom without compromising on width, Full XL mattresses are a versatile and comfortable option for a variety of sleeping arrangements.

Queen Size (60″ x 80″)

Queen-size mattresses, measuring 60″ x 80″, are the most popular bed size in the United States. They are an excellent choice for guest rooms and smaller master bedrooms, offering a balance of comfort and space efficiency. Queen beds are 6 inches wider and 5 inches longer than a full bed, providing more room for couples to sleep comfortably.

Each adult gets 30 inches of width, which is 9 inches less per person compared to a standard twin bed, but still offers a cozy and comfortable sleeping experience. The combination of ample space and versatility makes queen-size mattresses the go-to option for many households, ensuring a restful night’s sleep for both individuals and couples.

King Size, aka Eastern King (76″ x 80″)

King-size mattresses, also known as Eastern King, measure 76″ x 80″ and are an excellent choice for master bedrooms or other two-person sleeping arrangements where space is not constrained. Being 16 inches wider than a queen bed, an Eastern King provides each person with 38 inches of width, equivalent to the width of a twin bed.

For versatility, you can push two extra-long twin beds together to create the same size as an Eastern King. This makes it ideal for guest rooms, allowing you to use the twin beds separately or combined for couples. Additionally, King-size beds come with two half-width box springs, making them easier to move and manage. With its generous space and adaptable options, a King-size mattress ensures maximum comfort and flexibility for couples and guests alike.

California King Size, aka Western King (72″ x 84″)

California King-size mattresses, also known as Western King, measure 72″ x 84″ and are an excellent choice for taller adults. Offering 12 inches more width and 4 inches more length than a queen bed, a California King provides ample space for a comfortable night’s sleep.

Bedding for this size may be labeled either “California King” or “Western King.” These mattresses come with two half-width box springs, making them easier to manage and move. Each person gets 36 inches of width, ensuring a spacious and luxurious sleeping experience. Perfect for those seeking extra legroom and comfort, the California King is a top choice for master bedrooms and those who value expansive sleeping space.


What are the Twin XL and Full XL mattress sizes?

☕️ TL;DR

Extended-Length or XL mattress sizes provide extra length for taller individuals

Twin XL and Full XL sizes are variations of their standard counterparts, designed primarily for taller individuals seeking extra legroom.

Twin XL mattresses, also known as extra-long twin beds, are commonly found in college dorms and hospitals. Measuring 39″ x 80″, they maintain the width of a standard twin but offer an additional 5 inches in length, ensuring ample space for taller sleepers.

Full XL mattresses share the width of a regular full-size mattress at 54″ x 80″ but provide an extra 5 inches in length. This extension accommodates taller individuals comfortably, preventing their feet from hanging off the bed’s edge.

Both Twin XL and Full XL sizes are optimal choices for those needing additional length in their mattress to enhance their sleep experience. It is worth noting, however, that you can’t use regular Twin or Full-size bedding on the Extended-Length mattresses and your choice will be limited.


What is the difference between King-size and California King-size beds?

☕️ TL;DR

California King size is 4″ longer and 4″ narrower than the King (or Eastern King) size

The main difference between King-size and California King-size beds lies in their dimensions and how they fit into different bedroom layouts and personal preferences.

A King-size bed, also known as an Eastern King, typically measures 76 inches wide by 80 inches long, providing ample space for couples and individuals who desire plenty of room to stretch out comfortably.

In contrast, a California King-size bed is slightly narrower at 72 inches wide but longer at 84 inches, making it ideal for taller individuals who need extra legroom without sacrificing width. This additional length in the California King can accommodate taller adults or those who prefer more space at the foot of the bed. When choosing between the two sizes, consider your height, sleeping habits, and room dimensions to determine which size best suits your needs for a restful and spacious sleep environment.


What are the Twin/Full and Queen/King sizes?

☕️ TL;DR

Twin/Full and Queen/King refer to the under-bed drawers or bed frames that can be adjusted for different sizes

Twin/Full size usually refers to adjustable metal bed frames. The standard size of the twin mattress is 39″ x 75″ and the standard size for a full mattress is 54″ x 75″. Therefore, adjustable metal bed frames can be used for a twin mattress and expanded to accommodate a full size.

Queen/King size is also usually applied to adjustable metal bed frames. The standard size for a queen mattress is 60″ x 80″ and the standard size for a king-size mattress is 76″ x 80″. Once again, in this case, the adjustable metal bed frame can be used for a queen mattress and can be expanded to accommodate a king-size mattress.

There are also Universal, or Queen/Full/Twin, adjustable bed frames available on the market.

Twin/Full and Queen/King can also refer to under-bed storage drawers. Twin and Full beds are the same length and use the same set of storage drawers. The same applies to Queen and King size beds.


FAQs

How do I choose the right mattress size for my room?

Choosing the right mattress size for your room depends on several factors including the dimensions of your bedroom, your sleeping preferences, and who will be using the mattress. Start by measuring your room to determine how much space you have available. For couples, a queen or king-size mattress provides ample space for comfortable sleep, while a full size may be suitable for solo sleepers or smaller rooms. Consider whether you need extra length for taller individuals, in which case a Twin XL, Full XL, or California King may be preferable. Lastly, factor in any existing furniture or layout considerations that may affect the size and placement of your mattress within the room.

What is the difference between Twin and Full-size mattresses?

The main differences between Twin and Full-size mattresses lie in their dimensions and intended use. A Twin-size mattress measures 39 inches wide by 75 inches long, making it suitable for children’s rooms, bunk beds, and smaller guest rooms due to its compact size. In contrast, a Full-size mattress, also known as a Double bed, measures 54 inches wide by 75 inches long, providing more width for single sleepers or couples who prefer closer quarters. The Full-size mattress offers 15 inches more width than a Twin, accommodating growing children or adults who desire more room to stretch comfortably.

What is the difference between Full and Queen-size mattresses?

The main difference between a Full-size and Queen-size mattress lies in their dimensions and suitability for sleeping arrangements. A Full-size mattress measures 54 inches wide by 75 inches long, providing ample space for single sleepers or couples who prefer closer quarters. In contrast, a Queen-size mattress measures 60 inches wide by 80 inches long, offering an additional 6 inches of width and 5 inches of length compared to a Full-size mattress. This extra space makes the Queen size more comfortable for couples, allowing each person more room to move during sleep. Queen mattresses are popular for master bedrooms and guest rooms where space allows, accommodating two adults comfortably while still fitting within most room dimensions.

Will the mattress fit in my bed?

Determining if a mattress will fit in your bed depends on matching the dimensions of the mattress with those of your bed frame or base. Measure the inner dimensions of your bed frame or base to ensure it matches the dimensions of the mattress you intend to purchase. Additionally, consider factors like the height of the mattress and any headboard or footboard that might affect fit. Most standard mattress sizes (Twin, Full, Queen, King) are designed to fit corresponding bed frames or bases, but verifying measurements beforehand ensures a proper fit and optimal comfort.

Is a Full-size mattress suitable for couples?

While a Full-size mattress (54″ x 75″) can technically accommodate two adults, it may not provide sufficient space for most couples to sleep comfortably. Each person would have approximately 27 inches of width, which is significantly narrower than the 30 inches per person offered by a Twin XL mattress or the 38 inches per person provided by a King-size mattress. For couples who prefer more room to move during sleep or who have different sleeping habits, a Queen-size mattress (60″ x 80″) is generally recommended as it offers more width and length, providing better comfort and space for two adults. Therefore, while a Full-size mattress can work for some couples, a Queen-size or larger mattress is typically more suitable for optimal comfort.

What size sheets and bedding do I need for my mattress?

To determine the size of sheets and bedding you need for your mattress, match it to the corresponding mattress size. Make sure to choose fitted sheets that match the depth of your mattress, particularly if it’s thicker or has a pillow top. Additionally, consider the style and design preferences when selecting bedding to complement your mattress and bedroom décor.

What mattress sizes are available for RVs/trailers/campers?

When selecting a mattress for your RV, trailer, or camper, it’s essential to accurately measure the available space to ensure a proper fit for your specific vehicle or trailer model. Mattress sizes for RVs, trailers, and campers often differ from standard residential sizes due to space limitations and unique design requirements. Common options include Twin (39″ x 75″) or Cot (30″ x 75″) size mattresses, which are compact and suitable for smaller sleeping areas. Additionally, you can explore other common futon mattress sizes or opt for a custom-made mattress tailored to fit your specific dimensions and sleeping preferences.

Are there custom mattress sizes available and how do I order them?

Custom mattress sizes are available through select manufacturers who offer made-to-order options tailored to specific customer specifications. This service is particularly common for futon mattresses, where custom dimensions can be requested to fit unique frames or spaces. If you’re interested in ordering a custom-sized mattress, please reach out to us directly to discuss the available options and ensure your mattress meets your specific project requirements.

Each mattress size offers distinct advantages, catering to different preferences and room dimensions. By understanding these options, you can choose the perfect mattress to enhance your comfort and sleep quality.
