A comfortable and supportive mattress will do wonders for your sleep, but many problems that sleepers face are actually caused by the size of their bed. These problems can include tossing and turning, back pain, and waking up throughout the night.
In this article, we’re going to walk you through the most common bed sizes so you can choose the perfect size for your bedroom.
Crib beds measure 28” x 52”, and they are ideal for infants and toddlers. If you’re searching for a crib, there are a few important things you should know.
First, crib bed sizes and bed frames are standard throughout the industry, so any crib mattress you buy should fit into any crib frame. This makes shopping that much easier. Also, cribs have the same bed dimensions as toddler beds. They just have higher rails to prevent crawling babies from escaping, stealing your car, and driving to Las Vegas.
To save some extra cash, look for a crib bed that can convert to a toddler bed when the time comes. Then, you can use the same bed frame and even the same mattress (just make sure to accident-proof the mattress with a waterproof mattress cover).
Twin beds measure 38” x 75” and are popular with children and also adults when space is limited. Twin beds, as the name suggests, are often used when children share a room. They are also popular as a single bed in dorm rooms, guest rooms, and are commonly used for bunk beds.
Twin bed dimensions may seem restrictive, but they are a good choice for space optimization. A twin bed represents significant savings over a full-size bed or queen-size bed. If you have a small apartment or share a room, this may be the bed for you. Most twin bed frames are lightweight and simple to set up, and the beds are highly portable. Some even have wheels or can be folded.
If you move frequently or enjoy the life-changing feeling of rearranging your room every year or so, a twin bed will make things nice and easy.
The twin XL bed measures 38” x 80”. It’s the same width as the standard twin but 5 inches longer, perfect for accommodating the taller sleepers among us.
When purchasing a bed frame, twin XL bed dimensions can cause problems, so use caution. Many people mistakenly purchase a standard twin bed frame and are dismayed to find that their twin XL mattress doesn’t fit properly. This is why it’s so important to understand bed sizes and mattress dimensions — it can save you money and valuable time.
When shopping for a twin XL bed and a corresponding bed frame, make sure to measure carefully. Some adjustable bed frames claim to accommodate both standard twin and twin XL — but they sometimes stretch the truth. It’s always best to verify the frame length is 80 inches.
The full bed, also known as the double bed, is often touted as the standard bed size for single sleepers in terms of comfort and economy. Full-size bed dimensions measure 54” x 75”, which is the same length as a twin bed and 16 inches wider. The extra width allows for a companion, pet, or favorite body pillow. We also recommend full-size beds to single sleepers who are active during sleep or like to spread out.
Full-size bed frames are clunkier and not as mobile as twin frames, but because the full is still relatively compact, inexpensive and lightweight frames are easy to find.
Full XL Bed
The full XL bed, sometimes called double XL, measures 54” x 80”. It’s the same width as the standard full bed but has five more inches of length, which helps tall people from having to dangle their feet off the bed. It’s the same length as a queen bed, but 6 inches narrower, making it perfect for a tall, active sleeper.
When shopping for a full XL frame, make sure to double-check the bed sizes in inches so you don’t end up with a mismatched frame that only fits a standard full-size mattress and comes up short.
Queen size bed dimensions are 60” x 80”, which is a popular choice for the master bedroom. Queen beds are exactly 5 feet wide, which is six inches wider than a standard full bed. It’s also 5 inches longer than full and twin beds, making the queen-size bed great for most couples — you’ll get a good night’s sleep even if you toss and turn a little or are taller than average. However, if you also have kids or pets hopping into bed, you may find that a queen bed gets a little too crowded.
Because queen-sized beds are so popular, they’re priced very attractively, and it’s easy to shop for bedding and accessories. The queen strikes the perfect balance between spacious comfort and value. Versatile, spacious, and family-friendly, the queen size bed reigns supreme in the mattress world.
The king-sized bed is the widest bed on the market and provides the most luxurious sleep space available. King size bed dimensions are 76” x 80”, a whopping 16 inches wider than a queen. The king is ideal for those who enjoy the luxury of a large bed and is considered to be the best mattress for couples if you have enough space for it. Active sleepers can toss and turn and comfortably stretch out without disturbing a partner’s sleep.
King beds are also good for exceptionally light sleepers, as one partner typically can’t feel when another gets into bed or tosses and turns at night. Also, if you have kids or pets that like to cuddle in bed, the extra space a king affords can be a godsend.
California King Bed
Think of the California king-sized bed as the “king XL.” The California king bed dimensions are 72” x 84”, making this the longest bed you can buy. The California king bed adds 4 inches to the length of a standard king while cutting 4 inches from the width.
Very tall sleepers may want to invest in a California king, so their feet don’t dangle off the bed. Some people choose this size because they want a large bed at least 6 feet wide but find a standard king to be a little too wide for the shape of their room.
Be aware that shopping for a California king bed frame and bedding can be a bit tricky. Make sure that you get the right frame that fits the California king’s unique bed dimensions. Bed sheets tend to be more expensive and selection can be limited since the California king is in less demand.
Which Bed Size is Right for Me?
There are a number of things to consider when deciding which bed size is right for you. Before you purchase a bed, consider the following factors:
If you already have a mattress, this is the most important factor when determining your bed size. Use a measuring tape or check the label of the mattress to find its size in inches so you can buy an appropriate bed frame. The right bed frame also depends on the type of mattress you have, as memory foam and latex mattresses require different foundation support than a standard innerspring mattress.
Do you live in a house or an apartment? Do you have a large master bedroom? Is it on the second or first floor? These are just a few questions you need to ask yourself before committing to a bed size. Many people determine that they have enough room for a king bed but then realize that they can’t get their super-expensive antique frame up the stairs!
Also, consider the furnishings in your room. You may have the space to upgrade to a larger bed, but how will that affect your other furniture? Will you have enough space to walk around? When considering a new bed size, calculate the square footage of your room and measure the furniture.
Before buying a mattress and purchasing a bed frame, be sure to consider your height and weight, and the size of any sleeping companion as well. Heavier sleepers will need more support, so a cheap bed frame probably won’t be adequate, and certain mattress types support weight better than others. Tall sleepers need to consider legroom and may want to opt for a California king.
Your Sleep Style
Be sure to consider your sleep style. Are you a fetal-position pillow hugger, or a spread-eagle mattress hog? Do you toss and turn at night, or sleep like a rock? Knowing your sleep style will help you choose a bed size that provides the space you need. This is especially important if you share a bed.
Light sleepers and those who need more legroom should choose a larger bed, such as a queen or king. Those who like to snuggle close and can sleep through anything may be fine with a full bed. For single sleepers, a full bed should do the trick for any sleep style, unless you are tall.
Beds are notoriously hard to move and can easily get damaged. Before making a big investment in a new bed, it helps to wait until you’re settled into your current home. If you’re heading to college or move frequently, a twin or twin XL bed may be the best choice for the time being — even if you may prefer something larger.
Once you’re in your forever home, we highly recommend investing in a sturdy bed frame and a high-quality mattress with a great warranty.
When shopping for a new bed, the price is certainly an important factor. Regardless of how long you plan to stay in your home, you don’t want to spend thousands of dollars on an overpriced bed that you just don’t need.
The most economical bed size for couples is the queen. Inch for inch, it’s the best value of any bed size and the most popular mattress. However, if you’re single, you probably don’t need to spend the extra cash on a queen. A full bed is the right size for most single adults. If you don’t want to spend that much, twin beds are very affordable.
Bed Dimensions Guide
When it comes to bed sizes and dimensions, there’s a lot to consider. Are you feeling sleepy yet? That’s not boredom … it’s your innate desire to hop into a new bed and get the good night’s rest you deserve!
Remember to consider these important factors when shopping for a mattress or bed frame. Choosing the right bed size can have a big impact on your sleep, your health, and your relationships. Don’t make the all-too-common mistake of purchasing the wrong bed size, as this can create a huge amount of stress and can cost hundreds of dollars or more to rectify.
The most important factor when choosing between bed sizes and dimensions is your comfort. Buying a new bed is a big investment, so focus on the bed that’s going to leave you feeling rested and rejuvenated and soon you’ll be sleeping like a baby.
