Standard Bed Sizes

The largest standard bed size is the king size bed. A king size bed offers plenty of room for two people to sleep comfortably. It is also a great option for people who like to spread out when they sleep. The queen size bed is the next largest bed and is a good option for people who want more room than a full size bed but don’t need the extra space of a king size bed.


The twin bed is the smallest standard bed size. It is typically used for children’s beds or smaller adults. A twin bed typically measures 39 inches wide by 75 inches long.


A full size bed, also sometimes called a “double” bed, is the most common size of bed sold in the United States. A full size mattress is 54 inches wide and 75 inches long. These dimensions are the same as a twin size mattress, but a full is intended for one person instead of two. A full size mattress is a good choice for children who have outgrown a toddler or twin bed, or for adults who need more sleeping space than what a twin can offer but don’t have the extra room for a queen or king size mattress.

Full beds are also sometimes used in guest rooms because they can comfortably accommodate two people without taking up too much space in the room. When two people do sleep in a full sized bed, it may be a tight fit and not leave each person with much personal space. For this reason, many couples upgrade to a queen or king size mattress when they need more room to sleep comfortably.


A queen-size bed is one of the most popular bed sizes for couples and people who share a bedroom. It’s also a great choice for single sleepers who want more than enough room to stretched out. A queen bed is 60 inches wide and 80 inches long, making it perfect for couples who want ample space without going too big. side-by-side in the bed with plenty of room to spare, or you can each have your own space without feeling cramped.


A king-size bed is 76 inches wide and 80 inches long, making it the largest standard bed size available. It’s wider than a queen by 16 inches and 6 inches longer, giving each person about 2 extra feet of personal space. This added space can be important for couples who want to avoid rolling into each other during the night or for anyone who just wants more room to stretch out.

Custom Bed Sizes

The dimensions of a custom bed will largely depend on the available space in the room and how big the person sleeping in the bed is. That being said, the largest bed size would be a California king, which is 72 inches wide by 84 inches long.

A California king bed is slightly longer and narrower than a standard king size bed. It is also known as a “western king” or “western king bed”. A California king bed measures 72 inches wide by 84 inches long, making it ideal for tall people or couples who want extra leg room.

Split King

A Split King mattress is a great option for couples who want different customized firmness levels. It’s also a great option for single sleepers who want more space to move around. This bed size offers the same amount of sleeping surface as a King mattress, but it’s split into two halves. Each half can be adjusted independently, so you can have one side softer and one side firmer.

The Split California King bed is 72” wide and 84” long. This is the same length as a standard King, but it is 6” narrower. The two mattresses that make up a Split California King are each 36” wide, making them the same width as a Twin bed. This bed size is great for taller people who want more width to sleep comfortably, but don’t need the extra length that a standard King provides.

How to Measure for a Bed

When you are ready to purchase a new bed, you will need to know how to measure for a bed. The size of the bed will depend on the size of the room and the type of bed you want. You will also need to consider the type of mattress you want. The following paragraphs will explain how to measure for a bed and the different types of beds.


The standard length of a twin bed is 75 inches (190 cm), while a full-sized bed is 80 inches (203 cm) long. A queen-sized bed is usually 84 inches (213 cm) long, while a king-size bed measures about 80 inches (183 cm).


To find the perfect bed, you need to know how to measure for a bed. The width of the bed is one of the most important aspects to consider. You need to make sure that you have enough room for the bed, as well as any other furniture that you might want to put in the room.

The width of a bed is measured from one side of the bed frame to the other. This does not include any headboard or footboard that might be attached to the bed. The width of a king size bed is typically 76 inches (193 centimeters). A queen size bed is typically 60 inches (152 centimeters). A full size bed is typically 54 inches (137 centimeters). A twin size bed is typically 39 inches (99 centimeters).

When measuring for a bed, you also need to take into account any other furniture that might be in the room. For example, if you have a dresser next to the bed, you will need to make sure that there is enough room for both the dresser and the bed. You should also leave enough space around the edges of the room so that you can move around easily.


Before you purchase a new bed, it’s important to make sure that it will fit in your bedroom! To do this, you’ll need to take some measurements.

First, start by measuring the height of your bed frame. Most bed frames are between 18 and 24 inches tall, but you can find ones that are taller or shorter if you need them. If you’re not sure how tall your frame is, measure from the floor to the top of the frame.

Next, measure the thickness of your mattress. This is important because you need to make sure that there is enough space between the top of your bed frame and the ceiling for your mattress to fit comfortably. Most mattresses are between 6 and 18 inches thick, but some may be thicker or thinner.

Finally, measure the width and length of your bedroom. This will help you determine what size bed will fit best in the space. Keep in mind that you’ll need about 2 feet of space around all sides of the bed for it to fit comfortably.

Now that you have all of your measurements, you can start shopping for a new bed!
