Mattress Dimensions Guide
Crib/Toddler Bed Dimensions (28” x 52”)
Best Size For Infants & Toddlers
Standard crib and toddler mattresses will measure approximately 28 inches wide by 52 inches long. These mattresses are best suited for infants and toddlers who are still sleeping in cribs, or who will be transitioning to a toddler bed. Typically, you can use the same mattress for both bed types.
Crib/toddler mattresses are designed to last up until your child reaches 18 months or until they’re approximately 3 feet tall.
An important note: when shopping for a crib mattress, you’ll want to ensure that it’s as firm as possible. Infants have a tendency to roll onto their stomachs as they sleep, and if the mattress is too soft, they can be at risk for suffocation or SIDS (Sudden Infant Death Syndrome).
Twin Bed Dimensions (38” x 75”) OR Twin XL (38” x 80”)
Best Size For Toddlers, Children, Single Adults
The next step up from the crib/toddler mattress is the Twin size mattress option, which measures 38 inches wide by 75 inches long. If you’re looking for a mattress for taller sleepers, then you’ll want to look at a larger option known as the Twin XL, which can add an extra 5 to 6 inches in length. It’s recommended that you pick a Twin mattress for toddlers who have moved onto traditional beds, younger children and teenagers, and shorter single sleepers.
Full/Double Bed Dimensions (54” x 75”) OR Full/Double XL (54” x 80”)
Best Size For Children, Single Adults, Couples, Single Sleepers w/ Child or Pet
Full size mattresses measure 54 inches wide by 75 inches long, and they are sometimes referred to as “Double mattresses.” They are designed to accommodate children and single adults, and some shorter couples, but if the sleeper is taller, then it’s recommended that you look for a Double XL mattress option that adds an extra few inches in length. Also, be careful as a Full size mattress may be too small for adult couples that share the bed with their children or pets.
Queen Bed Dimensions (60” x 80”) OR Olympic Queen (66” x 80”)
Best Size For Single Adults, Couples, Sleepers w/ Child or Pet
Queen size mattresses are 60 inches wide by 80 inches long, and they can accommodate most adolescents, adults, and couples. For taller individuals, you can look up a larger alternative known as the Olympic Queen, which provides extra length. If you’re unsure about whether a Queen or King is right for you, check out our article on king vs. queen size mattresses.
King Dimensions (76” x 80”) and California King (72” x 84”)
Best Size For Couples and Couples with Children and/or Pets
A King size mattress is 76 inches wide and 80 inches long, while its larger counterpart, the California King, is usually 72 inches by 84 inches. Keep in mind that the California King may be longer, but it’s also slightly narrower, making it more ideal for thinner individuals. Both King size bed and California King size beds are great for a majority of couples with or without children and pets.
The Best Mattress Size for Couples
King: King beds offer a large amount of width and length, making them great for couples who share their beds with children or pets, but they may be too big for certain rooms. It’s best to keep a King mattress in a master bedroom.
Queen: Queen mattresses are large enough to accommodate most adult couples, but they may not be wide enough if you’re sharing with pets or children.
California King: A California King mattress is longer but narrower than a standard King size mattress. This makes it great for taller, thinner couples or individuals, but a Cal King may not be convenient for larger couples or people who share their bed with large pets and children.
The Best Mattress Size for Single People
King: A King size mattress is large enough to accommodate almost any size person, but it may be a little too much for younger children and smaller bedrooms. King size mattresses are best suited for couples or larger single adults.
Queen: A Queen size mattress can be a great option for most single people, providing enough length and width to ensure you have plenty of space to move around.
Full: A Full size mattress is excellent for children and teenagers who sleep alone, and it’s compact enough to fit into college dorm rooms and guest rooms, but if you’re a taller individual, it may be a little too short for you.
The Best Mattress Size for Children
Full: A Full size mattress is the right length and width for most children, and it’s compact enough to comfortably fit into smaller bedrooms. Taller children, however, may want to go for the Full/Double XL mattress option.
Twin XL: Twin XL mattresses are great for young children who have hit their growth spurt early and are tall for their age, but they may be a little big for very young children who are just transitioning to traditional beds.
Twin: A Twin mattress is a great sleep option for children who are moving on from toddler beds. It’s compact, but still large enough to give them enough sleeping space, and it can even be used for bunk beds if you have multiple children around the same age. If the child is getting close to becoming a teenager, a Twin XL may be better.
Factors To Consider Before Choosing a Size
There are various factors you will need to consider before choosing the right bed sizes for yourself. For example, who will be sleeping in the bed? Will you be sharing it with children or pets? Do you tend to shift or move a lot while you sleep? How big is the room? What is your mattress budget? You might have a particular size already picked out, but it’s a good idea to ask yourself these questions before you make your decision.
How many people (or pets) will be in bed?
You need to think about everyone who you will be sharing your bed with, whether it’s your spouse, your children, or your pets. More sleepers means a larger mattress will be necessary.
Are you an active sleeper?
If you’re one of those people who moves around a lot in their sleep, then you’ll want a larger bed to accommodate your nighttime shifts. This is especially important when you share your bed with someone, as moving around can potentially disturb their rest if the mattress is too narrow.
What is your body type?
If you are a larger individual, you will want a mattress that can support your size and stature. Make sure that you pick out a mattress that isn’t too small for you.
What are the dimensions of your bedroom?
It’s not just your body size that you need to consider when purchasing a new mattress. It’s also about your bedroom size. Look at the size of your room and determine what size bed will work without taking up too much space.
What is your budget?
Mattress pricing can depend on a variety of factors aside from size, such as manufacturer and materials. You want a mattress that gives you the best possible sleep environment, but you don’t want to go too far outside your budget. Carefully consider the amount of money you’re willing to spend on a mattress so that you aren’t breaking the bank with this purchase.
