Mattress Sizes Guide

Here is detailed information on the different sizes of mattresses, their dimensions, and the types of sleepers and room sizes they’re designed for:

Mattress Sizes Comparison Chart

Standard Mattress Sizes

Twin

Dimensions: 38 x 75 inches (96.5 x 190.5 cm)

A twin, or single, mattress is a great fit for a child, teenager, or single adult who doesn’t need a lot of sleeping space. Twin mattresses are also common in bunk beds and trundle beds. This size is great for maximizing floor space in a small bedroom, a studio apartment, or a shared bedroom.

Full

Dimensions: 54 x 75 inches (137 x 190.5 cm)

A full, or double, mattress offers more width than a twin, making it suitable for teenagers, single adults, or couples who don't mind close quarters. This size works well in smaller master bedrooms, guest rooms, or any room where you need to sleep two but want to conserve floor space.

Queen

Dimensions: 60 x 80 inches (152.5 x 203.5 cm)

A queen mattress is the most popular choice for couples and single adults who enjoy extra space. It will fit comfortably in most standard bedrooms while providing ample sleeping space for two people. This versatile size is suitable for most standard-sized bedrooms, master bedrooms, or guest rooms. It's ideal for couples who want more space than a full-sized bed but don’t want a bed as large as a king.

King

Dimensions: 76 x 80 inches (193 x 203.5 cm)

A king mattress offers luxurious space for couples who enjoy spreading out or families with young children who occasionally co-sleep. (Not to mention, it’s a great option for families who have pets, like big dogs, who like to share the bed!) This size is perfect for larger bedrooms, including master suites, providing maximum comfort and personal space for each sleeper.

Non-Standard Mattress Sizes

In addition to standard-size mattresses, taller individuals have some options.

Twin XL

Dimensions: 38 x 80 inches (96.5 x 203.5 cm)

A twin XL mattress is a popular choice for tall teenager and adults who need extra legroom but might have a small bedroom or be in a shared room. This size offers the same width as a standard twin but with about 5 additional inches (12.7 cm) in length.

This size is an excellent choice for growing teenagers or adults over 6 feet tall (1.8 m) who don't need additional width.

Full XL

Dimensions: 54 x 80 inches (137 x 203.5 cm)

A Full XL mattress is ideal for individuals or couples who need more width than a Twin XL but still want extra legroom. This size provides the same length as a Queen or King mattress, offering about 5 additional inches (12.7 cm) in length compared to a standard Full.

This size is a great option for taller adults over 6 feet tall (1.8 m) who prefer a more spacious sleeping surface without taking up too much room in the bedroom.

California King

Dimensions: 72 x 84 inches (183 x 213.5 cm)

A California king mattress is longer and slightly narrower than a standard king. It's ideal for tall individuals or couples who like a large bed and need extra length. This size works best in larger bedrooms and master suites.

Bed Sizes: Making the Right Choice for Each Sleeper

When selecting the right bed size, room size is always a factor. But what’s even more important is the specific sleeping needs of the person, or people, who will use the bed.

Here are some key factors to keep in mind:

Single Sleepers vs. Couples

For single sleepers, twin, twin XL, and full size beds are typically sufficient. These sizes offer ample space for one person to sleep comfortably. However, for couples, a full, or double, size bed might be tight. It really depends on how much room each person needs to stretch out.

Couples generally find queen, king, and California king beds more suitable. These larger sizes provide enough space for two people to sleep comfortably, even if one or both partners tend to move around during the night.

Family Considerations

If you’re a family who has kids or pets who occasionally crawl into the bed with you, extra space can be a good thing! Larger bed sizes offer enough room for the whole family, minimizing disruptions caused by late-night visitors.

Personal Sleep Habits: Morning People and Night Owls

Consider how close you and your partner like to sleep as well as the typical times you both get up and go to bed. For example, is one person a night owl while the other is a morning person? A large bed can help prevent accidental disturbances if one partner comes to bed late and one gets up early.

Matching Bed Size to Body Type

Another important factor to consider when choosing a bed size is the body size of sleepers. Here are some things to consider:

Height

Your height plays a significant role in choosing the right bed size. For example:

• For individuals under 6′2″ (1.9 m), most standard mattress lengths (twin, full, queen, king) will be suitable.
• For those between 6′2″ (1.9 m) and 6′7″ (2 m), consider a twin XL, queen, king, or California king for extra length.
• For sleepers over 6′7″ (2 m), a California king is ideal, offering the most length of any standard mattress size.

Width Requirements

If you need more space width-wise, consider these options:

• For average-sized individuals, a full mattress can provide adequate width for a single sleeper.
• For larger individuals or those who prefer more space, queen or king sizes offer additional width for more comfortable sleeping and movement.

Accommodating Sleep Positions

Your preferred sleep position can influence your bed size choice as well. Here are some factors to consider:

Back Sleepers

Back sleepers generally need less width, so a twin or full size bed might be sufficient. However, if you're tall, ensure you choose a length that accommodates your height comfortably.

Side Sleepers

Side sleepers often appreciate extra width to accommodate bending knees and elbows. A full, queen, or king size can provide this additional space.

Stomach Sleepers

Stomach sleepers typically spread out more, so a wider bed, like a full, queen, or king, can be beneficial.

Combination Sleepers

If you tend to change positions throughout the night, a larger bed size (full, queen, or king) can provide the space needed for comfortable movement without disturbing your partner.

Future Sleepers’ Needs

In addition to what each sleeper might need now, it’s also important to look to the future. After all, buying a bed is a long-term decision. For example, do you have kids who will soon be teenagers or will you be adding a new family member? Be sure to think through the life changes you and your family might be undergoing as you make your choice on the right bed size.

By considering these factors - who will use the bed, body type, and sleep positions, you can make an informed decision about the best bed size for your needs. Remember, the goal is to create a sleep environment that promotes comfort and restfulness, supporting the overall health and well-being of all sleepers.

Bed Sizes: Making the Right Choice for Your Space

In addition to matching bed size to each sleeper, the bed you choose obviously needs to fit well in the room it occupies. Here are some things to consider when choosing the right bed size for your room:

Matching Bed Size to Room Size

The image and table below are CozyBeds’ general guidelines for choosing the right bed size for your room.

Floor Space

Room size, or floor space, is another key consideration when choosing your bunk bed. Remember to add extra room for ladders, storage drawers, or desks. Here’s a guide for bed sizes based on room dimensions:

Keep in mind, these sizes are standard guidelines. However, you should always check the bed's exact dimensions in the product description for that specific design. By looking at your room's size and the bed's dimensions, you'll find the perfect fit. This ensures your space will be used well while offering a comfortable place to sleep.

Here are some ideas for the types of beds that will work well in various room sizes:

Small Bedrooms - Up to 150 square feet (45.7 sq. m)

In compact spaces, every inch counts. These beds will work well in small spaces:

• Twin or Twin XL beds are ideal, leaving room for other furniture.
• Bunk beds and loft beds: These designs take advantage of vertical space while having a small floor footprint.
• Murphy beds or wall beds: This design frees up floor space when the bed is not in use.
• Daybeds: This multifunctional design offers a sofa by day and a bed by night.
• Trundle beds: This style offers an additional sleeping space that can be tucked away when not in use.

Medium-Sized Bedrooms - 150-300 square feet (45.7-91.4 sq. m)

A medium-sized bedroom offers more flexibility when it comes to bed size. Consider these options for medium-sized spaces:

• Twin beds: Two separate twin beds can be ideal for guest rooms or shared children's rooms.
• Full size beds will leave room for additional furniture, such as chairs, couches, or desks.
• Queen size beds are a popular size, providing ample sleeping space without overwhelming the room.
• Murphy beds or wall beds: These are a great option if you use the room for multiple purposes.
• King size beds can fit but may limit space for other furniture.

Large Bedrooms - Over 300 square feet (91.4+ sq. m)

In spacious bedrooms, you have the luxury of choice. These options work well in larger bedrooms:

• King or California King beds can serve as a luxurious centerpiece.
• Multiple bed setups: For shared rooms, such as siblings’ bedrooms or vacation homes, triple and quad bunk beds or corner and l-shaped beds can be a great option.
• Canopy or four-poster beds: These statement pieces add drama and elegance to spacious bedrooms.
• Expanded headboards: Oversized or wide headboards can help fill wall space in larger rooms.
• Daybeds or lounges: Add these in addition to your main bed for an extra lounging area.

Multi Use and Shared Rooms

When furnishing multi use or shared rooms, bed size and additional features play a key role in maximizing space efficiency:

• Under-bed storage drawers can provide valuable storage space without increasing the bed's footprint, making them ideal for small rooms or shared spaces.
• Trundle beds offer a space-saving solution for guest rooms or children's rooms, effectively doubling sleeping capacity without permanently occupying floor space.
• In multi use rooms, such as a home office/guest room, consider Murphy beds or convertible sofa beds to free up floor space during the day.
• For loft beds, factor in headroom beneath the bed for desks, dressers, or play areas in children's rooms.
• For bunk beds, consider the full footprint of the bed, including ladders or steps. These access points typically extend the bed's footprint by 12-24 inches (30.4-61 cm).

Ceiling Height

Another important factor to consider when it comes to bed size is ceiling height. For loft beds and bunk beds, there should be enough ceiling space for the person who’s in the top bunk to sit up comfortably in bed. Typically, you need about 40 inches (1 meter) of space from the top bunk to the ceiling, based on the average height of an adult.

In rooms with low ceilings, consider a lower profile bed, such as a floor bed or horizontal wall bed, for a better fit.

Additional Bed Size Considerations

When choosing a bed, remember that bed frames and headboards can add several inches to the overall dimensions. In addition, mattress thickness, typically ranging from 8-14 inches (20.3-35.6 cm) adds to bed height.

Measuring Your Space

To ensure your selected bed will fit your space, be sure to measure your room's length and width, accounting for any irregular shapes. You can mark out the bed size on your floor using painter's tape for visualization. Ensure at least 24 inches (61 cm) of walking space around the sides.

In addition, consider the placement of windows, electrical outlets, and vents when planning your layout. And don't forget to measure doors and staircases for delivery access. By carefully considering these factors, you can select a bed that meets both your comfort needs and spatial constraints.

Budget Considerations

When it comes to choosing a bed frame size, it's important to remember that a higher price doesn't always equate to better quality. Many affordable bed frames offer durability and style without breaking the bank. Look for sturdy materials, like solid wood and metal, and pay attention to customer reviews and warranties.

Keep in mind that a well-chosen bed frame should last for many years, making it a worthwhile investment in your comfort and sleep quality. While larger sizes tend to be more expensive, don't rule out these options if they fit your needs and space – the long-term benefits of a properly sized bed and a good night’s sleep can outweigh the initial cost difference. Ultimately, aim to strike a balance between your budget, space requirements, and sleep preferences to find the best bed frame size for your home.

Mattress and Bed Sizes Matter for a Good Night’s Sleep

Choosing the right mattress and bed size is an essential step when creating your ideal sleep sanctuary. By considering your personal needs, room dimensions, and budget, you can find the perfect balance between comfort and space efficiency. Remember, the best mattress size is one that not only fits your bed frame and bedroom but also supports your sleep habits and lifestyle. So, you’ll get a good night’s sleep and energized days for years to come.
