    What is a Twin Size Mattress?

    The first thing your child needs while growing up is a twin mattress. Being the smallest mattress size, a twin mattress is an immediate base on which your child sleeps after graduating from a crib. A twin size mattress is not only for children but also for tiny and short people under 6 feet of height. 

    The smallest mattress size is available in two main dimensions: a standard twin mattress and a twin XL mattress. If you often notice your child bumping into the bed edge due to space crunch, it is time you invest in this twin bed. A twin mattress is also referred to as a single bed, but this is not a commonly heard term these days. Instead, the term ‘twin’ was attributed to the mattresses in pairs and were used as bunk bed mattresses or placed side by side. 


    Coming to the chapter that will convince you to buy a twin mattress. The conversation about twin vs full mattress might leave you baffled, but after considering the pros of the former, buying might become easier. 

    • Cheapest mattress for children’s room after crib mattress
    • Great for kids, toddlers, growing teenagers
    • Ideal for bunk beds, kids' room, and hostels
    • Suitable for seating purposes for guests during a party or similar events
    • Can be a great decor object to be placed in the drawing-room. Imagine how wonderful it would look in those colorful duvets. 


    Now, everything we like comes with specific cons as well. Same with twin mattresses, no matter how wonderful this purchase seems, considering the below cons will help with your decision of twin vs full bed. 

    • Not suitable for tall teens and adults
    • Cannot accommodate couples
    • A big ‘NO’ to restless or combination sleepers, you might roll over and fall
    • Your child may grow out pretty quickly
    • You cannot take your paw baby to sleep with you. It will create a space constraint for sure.

    What is a Full Size Mattress?

    A full mattress is perfect for adults who like that extra space in their beds. It is appropriate for teenagers, college students, and single adults. Also known as a double bed, a full bed mattress can accommodate two adults. But you will get a crib-like feeling if you’re sharing it with someone. So if you are choosing between a twin and full mattress for your guest room, blindly trust the latter as it is bigger. Though it might not be able to shelter two adults. 

    Remember the bed your parents used to sleep in? It is a full mattress, also known as a double bed. Previously, two adults would squeeze in a double bed. But now, mostly, it is used by single adults to sleep with enough space; they sometimes take their pets as well.  


    A full mattress or double bed is a good option for couples who like to cling to each other. Other than that also, the full mattress is pretty famous for all the underneath reasons. 

    • Perfect for tall teenagers and adults who like to sleep alone
    • Best-suited for guest rooms, dorm rooms, and smaller apartments
    • Accommodate more accessories compared to twin beds
    • Perfect for people who want to sleep with multiple pillows 


    A full bed has some factors to be disappointed about, and knowing these will ease your decision-making power to choose between twin vs full mattress.

    • Too small for couples who need personal space
    • Takes more room space compared to a twin
    • Costlier than a twin mattress

    Twin vs Full Mattress: 4 Steps to Follow Before Buying

    There is this utter confusion about the twin vs full mattress. The foremost reason lies with the subtle change in dimensions. As a newbie to bedding materials, settling down with one choice of mattress size can be troublesome. So, here are 4 easy steps to follow to figure out which mattress would suit your needs best.

    • Step 1: Measure the bed size that you are currently sleeping on.

    • Step 2: Study the size of your bedroom.

    • Step 3: Notice if there will be a space crunch if you opt for the full mattress instead of the twin mattress. If you feel like it, opt for a twin XL mattress.

    • Step 4: Notice the difference in dimensions stated below to understand better.

    How To Choose Between Full and Twin Mattresses

    If you don’t like to engage with numbers, then the following factors will be beneficial to help you understand what to choose between twin and full mattresses. Both mattress sizes are perfect for single sleepers and sometimes for two sleepers. But if you are inclined towards sleeping with enough space, then a full mattress or a twin XL mattress is for you.

    1. Price:

    Quite anticipated, a full mattress will cost higher than a twin mattress. And similarly, beddings, covers, blankets for a twin mattress will also be economical. Therefore, opt for it if you can suffice with a twin mattress. Otherwise, if you are a person who likes to sleep with their pet or that soft toy of yours, then a full mattress is perfect.

    2. Accessories:

    Accessories for twin mattresses are cheaper compared to full mattresses since they are smaller in size. While a twin mattress can fit only one pillow, a full mattress can fit in two pillows allowing more space to accessorize the bed. Twin size bedding such as duvets, covers, waterproof covers, and throw pillows is also cheaper than bedding for a full-sized mattress as they are different dimensions.

    3. Room Size:

    If your room is tiny, opt for a twin mattress. Though it should be said that any room can accommodate a full bed or twin mattress - they are real space savers. To be even more precise, for your kid or your studio apartment, select a twin mattress. Twin XL mattresses are generally noticed in dorms or studio apartments as they are slightly elongated and suit teenagers and young adults.

    4. Use:

    Twin beds are most functional for toddlers shifting from a crib to a bigger space. A twin mattress provides them enough space to play around on the bed. If you are blessed with two children, owning a twin bed would be perfect. Once you realize your babies are growing up, buy them a full bed.

    Twin vs Full Bed Size Variations

    Twin and full mattresses come in certain variations. These variations suit myriad factors like accommodating taller guests, college dorm rooms, accommodating growing children till their teenagehood, etc. Therefore, you must focus on all the variations, the dimensions, and the particular need you are buying the mattress for. Remember, you are spending your hard-earned money on it, don’t let it go to waste.

    Twin XL

    A twin mattress offers only one variable: a Twin XL mattress. Quite anticipated from the name, a twin XL mattress is the bigger version of the twin mattress. The measurements are 38 inches to 80 inches in length.

    If your kid is tall, or you want to invest in a mattress for the long term, then opt for a twin XL mattress - this way, you don’t have to worry about buying a new mattress once your child is on the verge of teenagehood. Another good use of twin XL mattresses is to accommodate different guest heights. You will also find these mattresses in college dorms as there are thousands of different students to hold.

    Full XL

    The full XL mattress is similar to the twin XL mattress - slightly elongated than the regular full bed mattress. However, its measurement goes up to 80 inches, 5 inches longer than the traditional full mattress. If you think of buying a mattress for anyone above 6 feet 2 inches, this one is the perfect mattress size. In confusion about twin vs full, a full XL mattress always wins for a taller person.

    Is a Full or Twin Better?

    A standard twin size mattress at 38 inches wide can only accommodate one person comfortably. However, it’s perfect for children transitioning from a crib mattress because of its compact size. It can also fit an adult but is better suited for teens and children due to the limited sleeping space. A standard full size mattress, the size right after twin size mattresses, is an excellent option for a single adult or adult with a child or a pet.

    A twin is better suited for a teen than a full bed, while a full mattress is for an adult. You have gained all the knowledge you need before hopping into the bedding store.
