Mattress Sizes Explained
Twin
Twin mattress bed dimensions are 38" x 74½". Twin beds are perfect for single sleepers. Being a little smaller, they are great for small spaces as they fit in most rooms and in small spaces. These mattresses are also great for children’s rooms as they do not need as much space on the mattress. Twin mattress depth dimensions differ based on the mattress.
Twin XL
Twin XL bed dimensions measure 38" x 79½" and are perfect for today’s taller sleepers. Twin XL mattresses are the same width as a Twin, but are 5-inches longer. These mattresses are great for small spaces as they do not take up as much room as larger mattresses. Being longer they are ideal for people who are taller than average.
Super Single
Super Single bed dimensions measure 47" x 74½" and are a throwback to the 1920s. They wereoriginally designed for one sleeper, but since bedroom space was so limited in the 1920s they often fit two people.These days, we get very few calls for Super Single's except for antique beds and military living quarters. As a result, we do not carry this size of mattress at Gotta Sleep as it is a less popular option.
Double / Full
Double bed dimensions measure 53" x 74½". Full bedsare designed for single sleepers who want something more room than a Twin. A double can sometimes work for a couple who have limited space.
Throughout the first half of the 1900's, full size mattresses were the standard for couples. After the introduction of the Queen mattress, the Full become almost obsolete.
Some couples may be able to make a Full size bed work, but since there is such a small price difference between a Full and a Queen, we recommend a Queen. Full mattresses offer inferior comfort, so unless you have a space constraint a Queen is likely best.
Full mattresses work great for children and are a cost effective option as the child will be able to fit the mattress for a significant period of time.
Double XL or Full XL
Full XL (Extra Long) bed dimensions measure 53" x 74½". The Full XL accommodates taller single sleepers who don’t have room for a Queen, but need something wider than a twin.
Full (double) XL mattresses are the same width as the Full, but are 5-inches longer. This is great for people who are taller than average. We do not carry this size of mattress at Gotta Sleep as it is a less popular option.
Queen
In looking at the weight, length, and width of a queen sized mattress, they are in the range of 55 to 100 pounds with a length and width of 60" x 79½".
Queen bed dimensions are 60" x 79½". Queen mattresses are the standard size of mattress for anyone sharing a bed with another person.Queen mattresses are ideal for couples who are looking for a cost-effective andspace-friendly mattress.
The queen sized mattress provides a enough amount of room for two people without overwhelming the room.The queen mattress is the most cost effective mattress as it provides enough space as a reasonable price. The Queen and King Mattresses are the most common bed size for master bedrooms.
Queen RV
A Queen RV bed dimensions measure 60" x 74½"and areessentially a Queen mattress that’s 5” shorter in length.
Queen RV's are generally found in Fifth Wheel and Holiday trailers, or where space is at a premium.
This size of mattress provides space for two people. Yet, it isslightly shorter to fit into compact spaces making it an ideal choice for camping.
King
King bed dimensions measure 76" x 79½". King beds are an excellent choice for couples who want the greatest amount of personal sleep surface. King beds are also great as they reduce sleep interruptions. King sized mattresses are ideal for larger spaces as they take up a considerable amount of room.King size mattresses provide a significant amount of space for each partner and are excellent for couples who like to spread out.
If you have children or pets who join youregularly in bed, a King size mattress will offer plenty of room as it is 16” wider than a queen. King mattresses are an excellent option for families who have the space for them.
California King
California King bed dimensions measure 72" x 83½".When it comes to a wider mattress for taller people sharing a mattress, nothing beats a California King.
Although not quite as wide as a King, the extra 5” in length can be a blessing for those who are taller. Having a mattress with a little extra leg space is perfect for those who are tall.
The California king mattress is also ideal for couples who have pets who sleep at the bottom of the bed. With a California King, you will have enough room for the pet without interrupting foot space.
As these beds are a considerable size, a significant amount of bedroom spaceis required to accommodate them.
Other Considerations
When making a decision on which size mattress is right for you it is important to consider a variety of influential factors.
Each of these factors play a significant role in sleep quality, comfort and can help to select the perfect mattress.Bycarefully selecting the size of mattress you are one step closer to ensuring you are able to receive a proper night's sleep.
Your height can play a large role in determining the perfect mattress size, especially if you are taller than average.If you are taller than average, a XL or California King mattress is ideal as they provide more length to accommodate longer legs.
When you are unable to fit your entire body on the mattress you arepotentially compromising your quality of sleep.With the wide variety of mattress sizes available people should not have to sacrifice comfort as a result of their above average height.The size of the bedroom or space where you would like to place the mattress is another factor to consider when choosing the perfect mattress.
A mattress too small or too large can offset the feel of the bedroom and leave it feeling empty or overloaded. If spaceis limited a smaller mattress is always recommended. Yet, if the room can accommodate a larger mattress having more space can result in a more comfortable sleep.
It is important to measure the space where you are hoping to put the mattress. This will inform how large of mattress you can buy.
For individual sleepers a twin or double size mattress will provide an adequate amount of room to ensure a good quality sleep.
Finally, if you share a mattress the larger the size of mattress you can afford the better. For mattresses shared between two people a double or queen sized mattress is ideal. They both provide enough space for each individual without taking up too much room in the bedroom.
When sharing a mattress with two adults and children or pets a King or California king sized mattress is best. This mattress size should onlybe considered if there is enough space in the bedroom.A king sized mattresses will provide space for two or more individuals to sleepcomfortably.
It isextremely important tothoroughly consider all these factors before deciding which mattress is right for you. By making the correct decision you will ensure you be on your way to having a good quality and restful sleep.
