Standard Bed and Mattress measurements

I'm sure that most people think they know the difference between a full, queen and a king size right? Sure, you know that the king is bigger, but do you know how much bigger and how much personal space each accomodates? Here is some information that I hope you will all find useful.Here's the skinny on Twin/Single and Extra-Long Twin Beds.
Twin beds are also known as single beds. They're the most common choice for children's rooms or multi-use guest rooms. These beds are narrow and fit easily into the smallest bedroom. Often twin beds have a "trundle" underneath to accommodate a sleep-over or second guest. Also used for bunk beds and two can be pushed together to make a king size. Usually too short for adults.
*Overall dimensions: 39" wide x 75" long" *Width per person: 39"

Twin Extra Long beds are 5" longer than a standard twin. They're often used in college dorm rooms to accommodate tall teens.
*Overall dimensions: 39" wide x 80" long *Width per person: 39"
Pros: The longer length is good for taller teens and adults. If you need flexibility in a guest room,
Cons: Bedding is difficult to find and not available in every pattern.

Here are the basic differences between a Full bed and a Queen: Full overall dimensions: 54" wide x 75" long *Width per person: 27" Queen overall dimensions: 60" wide x 80" long *Width per person: 30"
Full beds are 15" wider than a Twin, but if two share the bed, each has only 27" of personal space, much less than a twin which has 39"! A Queen bed is 6" wider than a Full bed, allowing more room for each person, but still 9" less than a twin bed.
Pros: A Queen Gives 2 adults more space than a double. The extra length (5") works well for most adults. Cons: Many people find a Full/Double bed too narrow for 2 adults and too short as well.

With two sizes of King beds and four names, it can get confusing when you go shopping for a King Size Bed. A Standard King is also called an Eastern King and a California King is also called a Western King. A Standard King is about 4" wider and a California King is 4" longer.

Two people sleeping in a King size bed will get the same amount of personal sleeping space as in a Twin bed. In fact, if you pushed two Extra-Long Twin beds together they'd be about the same size as an Eastern King.
Standard/Eastern King Overall dimensions: 76" wide x 80" long *Width per person: 38"
Pros: As the widest bed commonly available in stores, the Standard King is the most comfortable for two adults. The 80" length is sufficient for most people. Sheets labeled "King Size" fit a Standard King bed. The wide bed requires at least 3 standard or 2 queen or king pillows.

California/Western King Overall dimensions: 72" wide x 84" long *Width per person: 36"
Pros: A California King or Western King size mattress is wide enough for two to sleep comfortably and is the longest bed commonly available. It is 12" wider than a queen and 4" longer. Its extra length is good for tall people.
