Twin size beds, also referred to as single beds, are a great space saver. These beds are the second most popular mattress size after a queen size bed, and it’s easy to see why. Twin beds are ideal for small city apartments, dorm rooms, and children’s rooms. Also, when it comes to twin size bed frames, you have several different options, such as trundle beds and bunk beds.
This article will outline twin bed frame dimensions and styles so that you can find the right size for your bedroom, budget, and sleep needs.
Benefits of a Twin Size Bed Frame
Although twin mattresses are the smallest size available, they offer several benefits. Below, we highlight why a twin bed may be right for you.
Great for Growing Children
Young children outgrow their crib mattresses quickly, but they may not be ready for a full size bed just yet. A twin makes the perfect bed for toddlers and big kids. This size is big enough to accommodate them as they grow and may even be suitable throughout their teen years. Twin beds are also great for children because they don’t take up as much room, which will leave plenty of living space.
If your child is exceptionally tall, you can opt for a twin XL, which is 5 inches longer than a regular twin size bed.
Not only are twin beds one of the smallest sizes available, but they are also the least expensive. If you need a new bed for a child’s bedroom, a vacation home, or a guest room, a twin size bed is a cost-effective option.
Easy to Accessorize
When shopping for accessories, some items may not be as accessible for a larger bed. However, with a twin size mattress, bedding including sheets, duvet covers, and comforters, is widely available in a variety of colors and patterns, so it is easy to find those that fit your decor. Like twin mattresses, twin bedding is also less expensive than larger sized bedding.
Perfect for Small Spaces
Twin size bed frames offer more flexibility in terms of space. These beds are perfect for college dorm rooms, smaller apartments, and narrow bedrooms. If you have kids that share a bedroom, two twin beds will take up less room and give each child more personal space. Twin bed frames and mattresses are also lighter and more comfortable to move.
History of the Twin Bed
For many years, twin size beds were the most popular choice. Not only were they used for children, but married couples also slept in two separate twin beds. Today, most couples share a queen or king size mattress, but that wasn’t always the case. From the Victorian area to the end of WWII, it was common practice for a master bedroom to feature two twin size beds.
Types of Twin Size Bed Frames
The popularity of twin beds helped create several different types of bed frames, from platform beds and panel beds to more obscure frames. The following are eight of the most common twin size frames.
A panel bed frame is a basic design, consisting of two side panels, plus a headboard and footboard. Panel frames typically have a slatted foundation made of either wood or metal to support the mattress.
Platform bed frames sit low to the ground and are designed to support the mattress without an additional foundation, such as a box spring. These frames may have a slatted or solid wood base. Slats are usually spaced no more than 2.75 inches apart to support the mattress evenly.
Furnishing a small bedroom with two twin beds can be a great space saver for children that share a bed, but a bunk bed is even better. These frames consist of two or even three twin or twin XL beds placed on top of each other. Supporting a bunk bed are four pillars at each corner and two bed rails to prevent falling.
A loft bed is similar to a bunk bed, but the bottom of a loft bed features a small desk or sitting area instead of a mattress.
Daybeds, also called trundle beds, are a cross between a couch and a bed. These beds have a forward-facing frame with a back and two sizes. Instead of a headboard, daybed frames run along the side of the mattress, similar to a couch. Day beds are typically made of wood, metal, or a combination of the two.
Many daybeds also have a trundle. The trundle portion is another twin size mattress that sits beneath the bed. When guests come to visit, the trundle rolls out, creating one two-tiered bed. Trundle beds are a great way to save space and also have a comfortable place for guests to sleep.
A sleigh bed has a curved headboard and footboard that resembles a sleigh. These beds can have either an elaborate design with decorative curves or a more simplistic look. Sleigh beds create a focal point in the bedroom.
Four Poster Beds
Four poster beds, also called pillar beds, are one of the oldest styles used today. These beds have four tall pillars on each corner and are typically made of wood or metal.
Similar to a four poster bed, a canopy bed has four pillars that extend toward the ceiling. With a canopy bed, additional cross beams connect the four pillars to create a square shape frame above the mattress. Fabric is often draped from the canopy for aesthetic purposes or to create more privacy.
Twin Size Bed Dimensions
A standard twin size mattress measures 38 to 39 inches wide. A twin bed frame typically measures 44 to 45 inches wide, leaving approximately 3 inches of space on each side of the mattress.
Since twin mattresses measure 75 inches long, the side panels on a twin frame measure between 79 and 80 inches long, leaving about 2 inches of space at the head and foot of the bed to account for bedding.
Twin size headboards and footboards sit no more than 24 inches above the top of the mattress.
Twin XL mattresses measure between 38 and 39 inches wide as well, but XLs are 5 inches longer than standard twins. If you are planning to purchase a twin XL mattress, be sure to select a frame that will accommodate this extra length. If you already have a twin frame and want to use it with a twin XL mattress, you may be able to place extensions on the two side panels to add more length to the frame.
To make sure your twin mattress is supported correctly, you need the right foundation. Most frames have a built-in support base. If your frame doesn’t have a stable foundation, you can purchase one separately.
Hybrid and memory foam mattresses don’t need a box spring or any additional foundation for support. If slats are spaced no more than 2.75 inches apart, these beds can rest directly on the frame.
The foundations we offer at Amerisleep can be used as either a stand-alone base or they can be paired with any modern bed frame.
A solid mattress foundation consists of a wooden or metal box covered in cloth. A series of connected wooden or metal slats are placed at the base of the box to support the mattress. These slats are typically covered in a durable material to prevent sliding.
The Amerisleep Mattress Foundation is the perfect base for a memory foam or hybrid mattress. This base sits 8.5 inches high and has a sleek low profile look. With the optional leg attachments, the foundation has an overall height of 13.5 inches. The box and slat pack are made of solid pine wood to create a stable and durable base. Our slats are also wrapped in a breathable, no-slip fabric to keep them firmly in place and to increase airflow.
Adjustable frames allow you to raise and lower the foot and head of the bed to find a more comfortable sleep position. These frames can help improve circulation, alleviate back pain, and minimize snoring.
At Amerisleep, we offer two different adjustable frames—the Adjustable Bed and the Adjustable Bed+.
Our Adjustable Bed offers head and leg articulation with a whisper-quiet motor so you can make adjustments without waking your partner. It also has soft under-bed lighting for non-disruptive middle-of-the-night bathroom breaks. This foundation also works with most modern bed frames, thanks to its zero-clearance design.
The Amerisleep Adjustable Bed+ is similar to the standard model, but this base comes with several high-tech features—including Wi-Fi connectivity, under-bed lighting, wave massage, and programmable positions.
The Adjustable Bed comes with a 10-year warranty, and the Adjustable Bed+ comes with a 25-year warranty. You can bundle our Adjustable Bed+ with one of our advanced mattresses and save up to $1500 on the package.
Frequently Asked Questions
What size room works best for a twin-size bed frame?
Twin size bed frames are a good fit when you have limited space. If the room is at least 7 by 10 feet, a twin bed is a good option. This size bed will leave plenty of room for additional furniture, such as dressers and nightstands. A twin bed also leaves open space to move around the bed.
Are twin bed frames the same as single size bed frames?
Sometimes twin bed frames are marketed as single bed frames, but twin mattresses and small single mattresses do have different dimensions—to ensure you’re getting the right frame for your mattress, check the frame’s measurements. Twin mattresses measure 38 inches by 75 inches, while small single mattresses measure 30 inches by 75 inches. With an 8 inch difference in width, it’s safe to say a twin size mattress will not fit within a small single bed frame.
Can two people sleep in a twin?
In most cases, two people will feel cramped in a twin bed. These beds are designed for one sleeper. Two sleepers may be able to fit on a twin, but they may be forced to sleep in uncomfortable positions that cause aches and pains.
Are twin bed frames big enough for an adult?
Most single adults fit comfortably on a twin size bed. However, if you are over 6 feet tall, it is best to opt for a twin XL. Twin XL mattresses are 5 inches longer, so they offer taller sleepers more legroom.
What is the difference between a twin and a twin XL bed frame?
A standard twin mattress measures 38 by 75 inches, while a twin XL measures 38 by 80 inches. Twin size bed frames may not accommodate the extra 5 inches in length that comes with a twin XL. If you plan to use a standard twin frame with a twin XL mattress, you may be able to purchase extensions for each side panel.
Twin size beds are ideal for children and adults alike. These beds offer flexibility in terms of space and come with more bedding options. Due to their popularity, twin bed frames are available in a wide variety of colors and prints. Plus, these beds fit nicely into any budget. From bunk beds to day beds, twin size frames offer endless possibilities.
