Bed Frame Sizes and Their Dimensions

October 09, 2023 9 min read

Bed Frames come in all types, from foundation and platform frames to accentuated heavy-duty frames. They are also available in a variety of sizes, from single to super king. Well, it’s important to pick the right bed frame since it sets the foundation for a chic and warm bedroom. Here is all you need to know on choosing the size of your bed frame:

What Is a Bed Frame?

A bed frame is support that holds your mattress in place. It is also known as a bedstead comprising side rails, a headboard, and a footboard. They can be made of wood, metal, fabric, or a mixture of all. Some may be stand-alone, although they typically come with headboard and footboard attachments.

The purpose of a bed frame is to retain and support a mattress and base. Raising the mattress off the floor adds height and may make getting in and out of bed simpler. It’s also preferable to raise your mattress off the floor because this allows air to circulate beneath it and prevents mold growth.

Bed Frame Sizes

Bed frames come in a variety of sizes, with standard sizes being California king, king, queen, full, twin X, and twin. If you’re in search of a new bed frame, this is a standard rule of thumb: Take your mattress size and add 2 to 5 inches on each side. This extra space is for the structure of the bed frame and any special features it may have, such as shelves, upholstery, and drawers.

If you particularly want to upgrade from your current mattress to a larger one, thus a larger frame, start by measuring your bedroom to ensure enough space. A cramped bedroom can cause anxiety and make it difficult to fall asleep even with a stunning frame.

Standard Dimensions of a Mattress (From largest to smallest)

  • California King – 72 inches by 84 inches
  • King – 76 inches by 80 inches
  • Queen – 60 inches by 80 inches
  • Full – 54 inches by 75 inches
  • Twin XL – 38 inches by 80 inches
  • Twin – 38 inches by 75 inches

An In-Depth Understanding Mattress Size Dimensions

Twin Size

A twin-size frame is a perfect fit for a room size of 8 ft. by 10 ft.

From a crib to a toddler bed, next comes the twin size. The dimensions of a twin bed frame are 38 inches by 75 inches. Frames in the twin size are designed for children or solitary people.

This size is ideal for apartments with limited living space, such as studios or one-bedroom apartments. Their small size makes it easier to organize a small space and easier to move from one place to another.

If you have many kids, bunk bed frames may be a preferable alternative. Bunk beds maximize living space while also providing additional room for play areas.

Twin XL Size

This frame size is best for a room size of 8 by 10 ft.

Twin XL bed frames are akin to conventional twin bed frames, except they are five inches longer, measuring 38 inches by 80 inches. A twin XL bed is an excellent alternative for tall sleepers because of the increased length. Its compact size makes it ideal for singles, teenagers, and children, and it is easy to move.

Twin XL size frames are typically used in college dorm rooms mainly because their extra legroom allows people of all heights.

Full Size

A full-size frame can fit a room size of 10 by 12 ft perfectly.

A full-size bed frame, sometimes known as a double bed, is popular among teenagers and single people. At 54 inches by 75 inches, full bed frames provide you with 16 inches of additional space to stretch out. The extra space is also beneficial for restless sleepers who toss and turn during the night.

Full bed frames are also an excellent choice for single adults who are just starting on their own. They provide extra sleeping space, but they can also fit in studio apartments or modest bedrooms. Note that full-size frames are too small for a couple, but they’re perfect for a guest room.

Queen Size

This frame size can fit a room measuring 10 feet by 10 feet.

Queen size bed frames are the most popular frame size for single adults, measuring 60 inches by 80 inches. For single sleepers, queen mattresses provide greater space and luxurious size.

They also come in handy for some couples, although some may find them quite small. A queen frame is less expensive than a king or California king, but it still gives each person a comfy 30 inches of personal space.

Queen size bed frames, which can sleep up to two people, are also a good addition to guest rooms.

King Size

A room measuring 13 feet by 13 feet can be ample for a king-size bed.

The most popular bed frame for most couples is a king-size bed frame. The dimensions of a king bed frame are 76 inches by 80 inches, giving you more than 38 inches of personal space. If your children like to climb into bed with you at night, king-size frames are perfect for you.

King frames are ideal for master bedrooms due to their huge size. Smaller bedrooms may feel claustrophobic, especially if you add a king bed frame, which can take up to five inches more on each side.

California King Size

Like the regular king-size bed frame, a California king bed frame can fit in a 13ft x 13 ft room.

In the early 1960s, California king-size bed frames, sometimes known as western kings, were invented in Los Angeles, California. Cal king frames were seen as a more plentiful alternative to king-size frames.

California king bed frames are wider and longer than normal king bed frames, measuring 72 inches by 84 inches. The extra length is ideal for tall couples, and they will appreciate the 36 inches of personal space. California king bed frames are particularly ideal for master bedrooms with plenty of space.

Types of Bed Frames

There are many different bed frames to pick from, but the most common include four-poster, sleigh, bunk beds, platform, and panel frames. The first factor to choosing your preferred kind is your personal choice. This way, you can make a selection that matches your styles. You should also consider the cost and weight. A heavy frame, such as a four-poster or sleigh bed, may not be the greatest choice if you move frequently.

Panel

Panel frames support the mattress base and mattress. The panel’s surface typically comprises wood slats that add breathability to the mattress alongside a metal/wood headboard and side panels.

Platform

Platform beds are meant to support and hold a mattress without the use of a mattress foundation. Most mattress types, including memory foam beds, are supported by platform beds with flexible wood slats set 2-3 inches apart.

Platform bed frames have a simple appearance, although they may incorporate headboard or footboard attachments. One of the variants of the platform frame is a captain bed. To save space, captain beds have built-in drawers along the bottom sides of the frame. These kinds of frames are very popular in children’s rooms.

Bunk Beds

Bunk beds are made up of two or more bed frames stacked on top of each other. They can accommodate up to three people in the same space. The frame is made up of four pillars that support the bunk bed. This frame has a built-in side rail and an upper bunk. The side rails help to keep a person from slipping out of bed.

The majority of bunk beds are designed to suit a twin or twin XL-size mattress. However, some may be able to handle full-size beds. One variant of the bunk bed is a loft bed. It’s akin to a bunk bed, although it might have a workstation or small couch underneath the suspended bed.

Sleigh

Sleigh bed frames have a regal, opulent appearance. The beds are often composed of solid wood, making them heavier and more difficult to move than other bed frames; some may also feature upholstery.

Sleigh beds are a beautiful complement to any master bedroom and make a bold statement! Sleigh beds are distinguished by their curved or scrolled headboards and footboards, which give them their “sled-like” appearance. Curves on modern models are less accentuated and more minimalistic.

4-Poster

Four long columns extend towards the ceiling on four-poster bed frames. Older variants included a big rectangular panel that ran parallel to the mattress and heavy curtains wrapped around the bed. The nobles utilized these curtains not just for decoration but also for privacy from staff and to keep warm in drafty rooms.

Many modern four-poster frames lack a rectangular panel at the top of thick curtains. However, they may feature a canopy attachment. As such, you can wrap a thick or transparent fabric over the bed to obscure light or as a decorative element.

Bed Frames Materials

Wood and metal are the most common materials used in bed frames. Both materials are durable and supportive. Upholstered headboards and footboards may be included in some versions for a more modern look.

Wood

One of the most popular materials for bed frames is wood. Wood frames offer a timeless look and give a robust, stable foundation. Depending on the type of wood and frame structure, some may be heavy or difficult to lift.

Particleboard (recycled wood bits bonded and pressed together to produce solid boards) could be used in some wood frames. Vinyl is then used to coat particleboard to make it look like real wood grain. Particleboard bed frames are supportive and less expensive than solid wood bed frames, albeit not as sturdy or lasting.

Metal

Another typical frame material is metal. Metal frames tend to be more supporting, durable, and affordable than wood frames, albeit not as strong. However, they are a versatile addition since you can easily paint a metal frame if you want to alter up your bedroom design and theme.

Other Bedding Accessories You Should Consider

If you’re shopping for a new bed frame, consider if you already have a mattress foundation or if you want to add an adjustable base. Both of these factors may influence the sort of bed frame you select. A platform bed, for example, provides ample support for a mattress while obviating the need for a box spring.

Mattress Foundation

A mattress foundation is a bed structure with wood slats or innerspring coils on top. They provide stability and lift the mattress off the ground. There are various foundation types, a box spring being one of them. Box springs have a wood frame with innerspring coils that are wrapped in breathable cloth. The innerspring coils provide support and act as shock absorbers for the mattress.

Adjustable Base

Consider purchasing an adjustable base before purchasing a bed frame. Adjustable beds normally have electronic bases that raise or lower the body and can be used independently or in conjunction with a bed frame. An adjustable foundation is a great option if you have a split mattress, such as a king or Cal king.

It offers personalized comfort and support without waking up your sleeping mate. Special amenities, such as these may also be considered in adjustable beds:

  • USB charging connections
  • Under-bed illumination
  • Full-body massage

Conclusion

Creating the ideal bedtime setup is a matter of finding the perfect sheets, quality mattress, a comfortable pillow, and, of course, the best bed frame. This guide will assist you in selecting the finest option available! If you’re looking for the best bed frames, you’ve come to the right place.

FAQs

What is the standard height of a bed frame?

The height of a conventional bed frame ranges from 8 to 18 inches. The height varies depending on the manufacturer, frame type, and whether or not the frame has removable legs. Raising the mattress off the floor can help to limit dust exposure while also providing under-bed storage.

Is it necessary for the bed frame to be larger than the mattress?

The bed frame and mattress should be the same size. A queen-size bed, for example, should be supported by a queen-size frame. Purchasing a bed frame that is one size larger than your mattress can result in gaps, and the mattress may slide. Purchasing a bed frame that is one size smaller than your mattress, on the other hand, will not keep the mattress in place and may cause damage to both the bed and the frame.

Is it possible to sleep two adults in a twin bed?

Two adults may fit into a twin bed without falling out, but it will not be comfortable. Each sleeper will have approximately 18 inches of sleeping space—enough for some to rest on their side, but not much else. For couples, we don’t recommend anything smaller than a queen-size mattress.

Is it possible to fit a king bed in a 12 × 12 room?

A typical king mattress will fit in a room that is at least 12 feet by 12 feet. Other bedroom furniture, such as dressers, nightstands, lamps, and bookcases, should be able to fit comfortably inside the room’s dimensions. You should also keep some floor space free so that you may move around the room.

Is there a difference in size between a double and a full?

No, there is no difference. A full-size mattress is also known as a double bed. Even though it’s called a double bed, it’s only ideal for single sleepers. Couples sharing a mattress will have roughly 27 inches of sleeping space, about the same width as a baby-size mattress.
