Mattress Sizing Guide: What You Should Know Before You Buy a New Mattress

When it’s time to shop for a new mattress, you may feel overwhelmed. With so many brands and styles to choose from, it can be difficult to determine which one is the ideal match for you. Before you select one on a whim, though, it’s important that you take the time to consider the size of the room you’re furnishing as well as your unique sleep needs. Doing so will ensure that you are able to sleep well and feel your best for years to come. Check out these simple tips from the friendly team at Sam Levitz Furniture to help you find the right mattress for you.

Mattress Sizing 101

Whether you’re searching for a petite or spacious bed, you’re in luck. There are an array of mattress sizes available on the market today to choose from. To make your shopping experience as smooth and efficient as possible, it’s helpful to know the difference between these common sizes:

Standard Sizes

  • King: 76″ x 80″
  • Queen: 60″ x 80″
  • Full: 54″ x 75″
  • Twin: 38″ 75″

Specialty Sizes

  • Alaskan King: 108″ x 108″
  • California King: 72″ x 84″
  • Split Queen: 30″ x 80″
  • Full XL: 54″ x 80″
  • Twin XL: 38″ x 80″


If you love spreading out without getting in your partner’s way at night, a king mattress could be for you. Great for individuals who sleep with pets or children, as well as those who are tall, king mattresses encompass the equivalent of two twin size mattresses. While their large size may be ideal for a comfortable night’s rest, they usually don’t work well in small spaces. Even if they can fit comfortably in your bedroom, they may not be able to squeeze through narrow passageways or corners. It’s also important to know that they require special-sized pillows and bedding that tends to be more expensive than their smaller counterparts.


With a queen mattress, you won’t have to compromise comfort and space for size. While they’re slightly smaller than a king, making them fit into nearly any average size room, they still allow plenty of room for most co-sleepers. Because they’re America’s favorite sized mattress, queen bed frames and accessories can be found in a variety of prices and styles. Practical, comfortable, and affordable, it’s no wonder why people love them.


Sometimes referred to as a “double,” full size mattresses are smaller than a queen but bigger than a twin. A full mattress is spacious enough for one adult to sleep comfortably on but small enough to position in a tighter space. For these reasons, they are ideal for teen or guest rooms, starter homes, or anyone on a tight budget. Their versatility make them a great investment, since they can easily transition from one room to the next as your home’s needs evolve.


If your room is small, a twin mattress is the size for you. Twin mattresses are perfect for children’s rooms, but they can also accommodate one average size adult as well. Their small size and light weight makes them optimal for rooms that are tiny or a peculiar shape, or are perfect for use in bunk beds or positioned side by side in a guest room.

5 Tips to Know Before You Buy a Mattress

Once you’ve determined the best size mattress for your needs, it’s time to start shopping. To make your experience a breeze, keep these 5 tips in mind:

Measure Your Room

If you do nothing else before you purchase a new mattress, you must measure the room that the mattress will be in. Along with how big the space itself is, be sure to consider the size of any other furnishings in the room, how much walking space you’d like to have, as well as the size of the stairways, passages, and doors that the mattress will have to travel through to get to its resting place. A new mattress won’t do you any good if it can’t fit in your home.

Set a Price Point

Mattresses can get expensive. Before you step foot in a furniture store, know precisely how much you are willing to spend. Once you’ve established a budget, stick to it. Only look at the mattresses that you can afford. If you find that the mattresses within your price point aren’t fulfilling your requirements, you can pinpoint what specific feature you’re willing to invest more money into, such as the ability to sit up and recline.

Research Online

What do other people have to say about the mattress you’re interested in buying? Read online reviews to find out. Doing so may enlighten you on positive and negative factors that you never considered before. Additionally, seeing what other real-life people like and dislike about their mattresses will help you think of questions to ask when you are shopping in a retail store.

Try Mattresses Out in Person

You’ll never truly be able to tell if a mattress is a good fit for you without feeling it for yourself. After you’ve established what you’re looking for, go lay down on one. Even better, try out many different mattresses in the store to see what subtle nuances work best for you. Don’t forget to bring a notepad! You’ll want to remember which ones you like and why.

Check Warranty

Before you invest in a new mattress, make sure you’re familiar with its warranty. Nowadays, most brands provide a money-back guarantee for a particular period of time that allows you to bring the mattress home and try it out for a while. Along with how long you’re able to try it out, be sure to look at how long the warranty is good for. A longer warranty could save you the hassle of having to shop for a new mattress in the near future.
