Twin Bed Frame

Dimensions: 38 inches by 75 inches

Stepping up from the bed size of a crib or a toddler bed, a twin size bed frame is your ideal bed frame size if you are looking to get your teenager a separate bed. It is also perfect for single individuals who live in a studio or one-room apartment. In addition, we find it a great fit for smaller rooms as it is compact, making it easier to move. Its bed frame dimensions are 38 inches by 75 inches. 

Twin XL Bed Frame

Dimensions: 38 by 80 inches

The “XL” in the name suggests better spacing, which is why its bed frame dimensions are 38 by 80 inches – an extra 5 inches for taller children than the average height. Twin XL is a variation of the standard twin bed frame size and can only accommodate one person’s comfort. It suits best smaller spaces and single individuals. 

Full Or Double Bed Frame

Dimensions: 54 by 75 inches

As the name suggests, it can accommodate two people to sleep comfortably. Double Bed Frame dimensions are 54 by 75 inches, making it a fair choice for partners, couples, or sleepers with a pet. This bed frame size is suited to most bedrooms and could work well in your home’s guest room.

Queen Bed Frame

Dimensions: 60 by 80 inches

If you are a single sleeper looking for a luxury size bed and comfort, this bed frame size could just be the perfect one for you. Its dimensions are 60 by 80 inches seems, which suits many couples. In addition, the variety of bed accessories and mattresses crafted to suit this bed frame size are too many to count. However, if you are someone who shares their bed with children or pets, it might not be the perfect choice for you.

King Bed Frame

Dimensions: 76 by 80 inches

Known to be the widest standard bed frame size available in the market, the King bed frame comes with a comparatively bigger price tag. Its dimensions are 76 by 80 inches. However, as this bed frame size is as recommendable, it needs a larger room and may be a little difficult to move. 

California King Bed Frame

Dimensions: 72 by 84 inches

Known as the longest standard bed frame size available in the market, California King Bed Frame has 4 extra inches to offer than the standard king size. Unfortunately, as convenient as this bed frame size is for tall sleepers, it is pretty difficult to find mattresses and/or sleep accessories for this one. 

Specialty Bed Frame Sizes

Usually, the bed frame dimensions are made according to the six standard bed frame sizes we just talked about above. But, there are special cases or exceptions where oversized mattresses like the Alaskan King or family-size mattresses call for customization.

Others in this category can include bunk beds. Similarly, Murphy beds and trundle beds bring the ease of putting the mattress away while it’s not in use. Unfortunately, these specialty bed frame sizes come with unique designs and uneven measurement that makes it look like double the furniture it already is. 

Bed Frame Height

Bed frame sizes are determined to ease sleepers’ need to nap. Usually, the normal height of a bed frame is on the knee level, 12 to 16 inches tall. This height is calculated by keeping the average adult measurements in mind.

The reason to have the aforementioned height is to make sure adults can have their feet on the ground while keeping their knees bent and when sitting on the edge of the bed. 

Bed frame height varies differently based on the bed frame style and usage intent. For instance, taller bed frames are great as they offer extra storage. However, modern bed frame sizes are designed low in height to make sure the mobility of the elderly doesn’t become a problem. Then there are adjustable bed frames that allow you to change the height of various bed areas as per your need. 

Types Of Bed Frames

Like different bed frame sizes, there are various types of bed frames. With the years passing by and the upgrade of technology, the designers are coming up with amazing types of bed frames to meet our daily suitability needs. Let’s take you through them all, one by one:

Panel Bed

This bed frame consists of a four-panel frame, including a headboard, footboard, and two panels. Majorly made out of wood, panel bed frame dimensions tend to be very sturdy. They are usually combined with a box spring foundation for the best experience. 

Platform Bed

Known to have a simple and minimalistic look and feel, platform bed frames have slatted wood, solid wood, or a metal platform that takes away the importance of laying a separate foundation in the first place. These bed frame sizes may or may not have headboards and footboards.

Bunk Bed

A bunk bed has two beds stacked one above the other and a ladder to reach for the one above. Known as one of the most popular bed frame sizes, it is largely used in dormitories, hostels, or barracks. However, if you want to accommodate many people in a smaller space, this can be your ideal solution. 

Loft Bed

A loft bed has a similar feel to the bunk bed, as we discussed above. The major difference is that the loft bed has a space on the ground or base level. So, if you need space but have to make just one person sleep, a loft bed can be your perfect bed frame size. 

Sleigh Bed

This bed frame size has been popular in the United States since the 19th century. It resembles a sleigh, featuring a curved headboard and footboard and sometimes raised edges on the side panels. Though it is made traditionally from wood, the modern creations of this bed frame type are in metal, too, forming lesser exaggerations of curves. 

Four Poster Bed 

Like the name, it is designed to feature four tall posts or corners on each of the four corners consisting of the bed frame. In addition, many bed frame sizes are designed with an upper rectangular support structure, known as a tester. It is used to install curtains or a canopy, as the need be to provide privacy. 

Adjustable Bed

This bed frame type has a multi-hinged lying surface that can be made to profile in various positions per your comfort. This bed frame size is suited best for people who wish to work late or who like to fall asleep while watching a movie.

Storage Bed 

A storage bed frame size includes built-in compartments meant for storage underneath the mattress. It is a good option for sleepers who have limited space. It comes in many forms. The most popular one is – the captain’s bed which has a set of drawers on both sides of the bed frame below the mattress. 

Trundle Bed

This bed frame type contains a rolling platform to stow another mattress beneath the primary bed. This bed frame size is a great space saver and works well for those who do not have a guest room and need to accommodate more people in a limited space. 

Bed Frame Materials

Your bed frame material should be aiding you in giving strong foundational support to your bed. No matter your bed frame size, having the right construction material is the key to investing in the right place. There are basically two materials used to make any kind of bed frame size or match any bed frame dimensions given – wood and metal. 


Wood bed frames are made of solid wood. Oak, birch, and pine are some of the most common solid wood materials used to construct bed frame sizes. These are sturdy, stable, and less likely to wobble but are heavy to lift or move. 


Being a fairer, durable, and less expensive option, metal is used to construct bed frame sizes that are lightweight and offer low maintenance compared to the ones made out of wood. 

How To Choose A Right Bed Frame?

Buying the perfect bed frame for yourself is a big investment and a long-lasting one. Therefore, the right bed frame size should be bought after looking into multiple factors like:

  • Occupancy: The number of people you are looking to accommodate in a bed frame size should be the first factor to consider. We suggest that if you are a couple or share your bed with children, try opting for a King size or California King Bed Frame Size. Similarly, if you are a single sleeper, you may go for Twin Bed Frame Size or Twin XL Bed Size. 
  • Cost: It is vital to take your budget into your thought process when looking for the right bed size for yourself. Check for the best prices online, or go for it when offers are going on during the festive season to get the best for yourself. 
  • Size Of The Room: If you are having space issues and the number of people to be sharing is more, you must look for those bed frame sizes that are adjustable and do not take up a lot of space, for instance, bunk beds. 
  • Comfort: When looking for bed frame sizes or mattresses, having your comfort as a factor is necessary to make the right decision. 


Bed frame sizes play a crucial role as you would be spending a large portion of your day on them. There are various kinds of bed sizes to consider. But it just gets more complicated when you do not know what you want. Just like the bed sizes vary, so do the types of beds. There is something in store for everyone, and all you need to do is look carefully at your needs and pick accordingly. You need to look at the bed frame dimensions per your bed type and consider the variable factors like comfort, cost, occupancy, etc. 


 Bed frames are necessary if you need to feel supported while you sleep.

The standard bed frame height is between 12 to 16 inches. 

No. The bed frame size and the mattress size need to be the same. 

 If your bed frame size is bigger than the size of your mattress, here are a couple of things we can suggest:

  • Change your mattress as per the bed frame size
  • Use pillows to fill the gap
  • Remove the headboard 
  • Rotate your bed

Your bed frame size should be approximately 2 to 5 inches wider on both sides than your mattress. 

Yes. However, you must know that your mattress is bigger than your bed frame size.
