These two sizes are compact, making them ideal for single sleepers, and in this blog, we’ll explore the various aspects of each size to help you make an informed decision. Whether you’re looking for a firmer or softer mattress, we have the perfect bed for you at Sleep Cheap Mattresses.

What is a Twin Size Mattress?

A twin-size mattress is the smallest of all standard-size mattresses, measuring 38 inches in width and 74 or 75 inches in length. These mattresses are popular for their affordability, with prices ranging from $250 to $300. They’re a great option for parents of small children, who are transitioning from toddler beds, and for anyone who is looking for a budget-friendly mattress option.

The Pros and Cons of a Twin Bed Twin beds are a great choice for single adult sleepers, teens, or young children. Here are some of the pros and cons of sleeping on a twin bed:


  • Parents love twin beds for their small size, which makes them easy to fit into a child’s room. They’re also often paired with bunk bed mattresses, making it simple for parents to find beds for siblings.
  • If you have a large bedroom, you can place multiple twin beds in the room without feeling cramped. This was the original idea behind twin and single mattresses – a twin mattress is meant to imply that the bed is half of a pair, while a single mattress is a standalone bed.
  • Twin beds are widely available and easy to find, and you’ll be able to find bedding and accessories to fit them easily. They’re also budget-friendly.


  • As the smallest standard mattress size, twin beds are only 75 inches long, which might not be suitable for taller adults or teens. If you’re looking for a larger option, you may want to consider a twin XL mattress.

What is a Twin XL Size Mattress?

Twin XL size mattresses measure 38 inches by 80 inches, providing more legroom than a standard twin bed. They are suitable for single sleepers, adults, and children, and are especially ideal for taller sleepers over 6 feet. These mattresses are a great choice for a guest room or a college dorm room, offering simple and compact accommodation for solo visitors.

Assessing the Pros and Cons of a Twin XL Bed Twin XL beds are another great option for single sleepers. Here are some of the benefits and drawbacks of these beds:


  • With 5 extra inches of legroom, twin XL beds offer more space for taller sleepers. They have the same length as queen mattresses, making them a great option for single sleepers.
  • College students often prefer twin XL beds, as they fit in most college dorm rooms. These beds provide comfort for students who are away from home, and parents can plan ahead for their children’s future needs by choosing a mattress that will provide comfort when they move out.
  • Twin XL beds offer a comfortable sleeping experience for solo sleepers.


  • Twin XL beds are a little more expensive than twin beds, and their accessories can also be pricier. Not all mattress manufacturers offer twin XL as an option, so it may be more difficult to find one. Additionally, twin XL mattresses might come with a higher price tag.

Other Mattress Options for Single Sleepers

Twin and twin XL beds are not the only mattress sizes available for single sleepers. Full and queen mattresses are also a great investment for those who want more sleeping space. Let’s take a closer look at these two mattress sizes.

  • Full: Full or double mattresses are slightly wider than twin beds, measuring 54 inches in width and 75 inches in length. They offer more room for a single sleeper than a twin bed, making them a good option for those who have outgrown their twin bed. However, they are not suitable for couples, as there is not enough room for two people to sleep comfortably.
  • Queen: Queen-size mattresses are the most popular mattress size, providing comfort for single sleepers and couples. They measure 60 inches by 80 inches, offering equal sleeping space for partners. Queen beds are also affordable for the average sleeper and are not the largest standard size, so they can easily fit into most bedrooms.

It’s recommended to have at least 10 feet by 10 feet of space in your bedroom to fit a queen bed comfortably. If you have a smaller bedroom, consider a full or twin bed to save space.

How to Select the Ideal Mattress

When choosing a mattress, it’s essential to consider your room size and budget. Here are some factors you should keep in mind to find the best mattress for you.

Room Size

Consider the size of your bedroom before purchasing a mattress. A mattress that is too large will overcrowd your space, making it uncomfortable and affecting your sleep. Aim to have about 3 feet of space around the bed. For twin beds, the ideal room size is at least 9 feet by 9 feet. A full or queen mattress will work best in a room that’s at least 10 feet by 10 feet.


Queen, full, and twin beds are budget-friendly options, with most quality mattresses costing between $200 and $700. Some materials, such as latex foam or memory foam, may raise the price, with some costing over $1,000. However, these materials are a better long-term investment as they are less likely to become damaged and can last 15-20 years.

Number of Sleepers

Single sleepers can be comfortable on any of these beds, but some individuals may prefer more sleeping space. Couples or that co-sleeping with children will not be comfortable on a twin bed and should consider a larger mattress, such as a queen or king size. Twin beds are only suitable for single sleepers, and taller sleepers may need a twin XL mattress.

Personal Preferences

Your personal preferences are a crucial aspect of choosing a mattress. The mattress’s firmness will determine its comfort level. Consider if you prefer a soft or firm mattress. A firmer surface may be necessary for some sleepers to support their body, while a soft surface can be uncomfortable for those over 150 pounds. For side sleepers, a plush bed is recommended to support sensitive areas like the neck and side. Back, stomach, or combination sleepers need a firm, sturdy surface to keep their spine aligned. A mattress for back sleepers should be gently firm, medium-firm to firm, or medium. A mattress for stomach sleepers should be firm. A mattress for combination sleeping should be medium to medium-firm or a hybrid mattress.

FAQs on Twin and Twin XL Mattresses

Which is better for bunk beds: twin or twin XL?

Both twin and twin XL mattresses can be used for bunk beds. However, it’s important to check the dimensions of your mattress to ensure it fits the frame properly. Twin mattresses are 38 inches by 75 inches, while twin XL beds are 5 inches longer.

Will my kids outgrow their twin XL bed?

It depends on your child’s sleeping preferences. Twin XL beds are suitable for sleepers who are taller than 6 feet, so your kids may not outgrow them as fast as a twin bed. However, if they like more room to sprawl out, a full or double bed may be a better choice.

Can twin sheets fit on a twin XL bed?

No, twin sheets won’t fit on a twin XL bed. Twin XL beds are 5 inches longer than twin beds, so it’s important to use the correct sheet size to keep it from slipping off.

Is a twin or twin XL better for an adult?

Both twin and twin XL mattresses are suitable for adult sleepers. However, most adults prefer the extra legroom offered by a twin XL bed.

How much should I expect to pay for a twin or twin XL mattress?

Twin beds are the most affordable standard-size mattress. You can find quality twin beds starting at around $300. Higher-end twin beds with features like latex or gel foam can cost upwards of $600. The price of twin and twin XL beds is typically similar, so comfort should be the determining factor when choosing between the two.
