Full vs Twin XL Bed: What’s the Difference?

When shopping for a new bed, Twin-size mattresses and Full-size mattresses may seem somewhat similar. Both are more affordable and narrower than the popular Queen-size bed, and both are commonly used in children’s rooms and college dormitories. However, each mattress size has its own set of unique features, benefits, and drawbacks. So, which is the right choice for you? Let’s dive into the details of our Full vs Twin XL comparison to help you decide.

Full vs Twin XL Mattress Comparison

For a quick comparison between a Full-size and Twin XL mattress, check out the chart below:

Standard Full-Size Mattress

The Full-size mattress (sometimes called a Double bed) is similar in length to a Twin bed, though it offers more width. However, it is still relatively small for couples. Each person gets only 27″ of width, which is the width of a crib. As the Better Sleep Council suggests, many parents are choosing Full-size beds for their teenagers or even younger children, offering them more space than a Twin.

Dimensions

• Width: 54″
• Length: 75″
• Width per Person: 26.5″

Pros

• More spacious than a Twin XL, providing better comfort for individual sleepers.
• Easy to find accessories like sheets, comforters, and mattress pads.
• Works well in small bedrooms and guest rooms.
• A good option for growing children and teens.

Cons

• More expensive than a Twin XL mattress.
• Too small for most couples (though some can manage with it).
• Too short for taller individuals.

Additional Full Mattress Sizes

• Full XL:
  The Full XL is the same width as the standard Full but adds 5″ of extra length, matching the length of Twin XL, Queen, and King mattresses. If you need a larger bed but don’t want to upgrade to a Queen, a Full XL could be the perfect option.

Dimensions

• Width: 54″
• Length: 80″
• Width per Person: 26.5″

Twin XL Mattress Size

The Twin XL is the same width as a standard Twin bed (38″) but is 5″ longer, matching the length of a Queen or King mattress. It’s a popular option for college dormitories, taller children with smaller rooms, and hostels. Additionally, two Twin XL beds placed together can be used to create a Split King bed.

Dimensions

• Width: 38″
• Length: 80″

Pros

• More affordable than a Full-size mattress.
• Comfortably fits taller sleepers.
• Great option for children.
• Common in college dorm rooms.
• Easy to find accessories for.
• More portable than a Full-size bed.
• Can be paired with another Twin XL mattress to create a Split King.

Cons

• Doesn’t fit couples.
• Smaller than a Full-size mattress, making it less ideal for those who want more space.

Additional Twin Mattress Sizes

• Standard Twin:
  The Standard Twin (also known as a Single bed) is typically the next step for children transitioning from their cribs. It works well in small bedrooms, guest rooms, and bunk beds.

Dimensions

• Width: 38″
• Length: 75″

What Size is the Best for You?

Who Will Like the Twin XL?

The Twin XL is perfect for people who need extra length but are tight on space. By saving about 15″ of width compared to a Full bed, it’s ideal for narrow bedrooms where length is more important than width. If you have space for extra length but don’t want to sacrifice too much width, the Twin XL offers a great solution.

If you’re trying to save money, Twin XL beds are more affordable than Full-size mattresses, and you’ll find that bedding for Twin XL mattresses is often less expensive as well. Additionally, if you have creative plans like building a Split King bed, two Twin XL beds can be placed together to create the perfect King-sized bed.

Who Will Like the Full?

The Full bed works well for couples who are tight on space. While it offers more width than a Twin XL, it still may feel cramped, with each person having only 27″ of space. If you’re looking for something larger, consider upgrading to a Full XL for an extra 5″ of length.

If you have a larger room to fill, the Full-size bed offers 15″ more width compared to the Twin XL, which is perfect for better filling the space. For growing children, the Full bed offers more room than a Twin mattress and provides more comfort as they grow.

Things to Consider

Choosing between a Twin XL and a Full comes down to what will fit best in your space. Keep these considerations in mind before making your purchase:

• Measure your space and leave room for movement. If you’re moving up from a crib or Twin to a Full/Double or Twin XL, make sure it fits comfortably in your room. It’s easy to make an impulse decision and end up with a mattress that doesn’t fit your space. Many designers recommend leaving at least 30″ of space around the bed for movement.
• Consider who will be sleeping in the bed. Will this be for a child, guest room, or couple? Think about whether two people will be sleeping in this bed. If so, you might want to go with a Full or Full XL for more space.
• Shop seasonally if possible. Twin XL and Full beds are popular for children, teens, and college dorms. Back-To-School shopping season in Fall is a great time to buy, as it often comes with good sales. Similarly, Labor Day and Memorial Day weekends are often good times for mattress deals.

Overall

Both Twin XL and Full/Double beds are great choices for smaller rooms. The Full-size bed offers extra width for more space, making it a better fit for couples or those who need more room to grow. On the other hand, the Twin XL is an excellent choice for individuals who need extra length without taking up too much width, and it’s perfect for tight spaces.
