King-size mattresses measure 76 inches wide by 80 inches long.

High-quality mattresses should measure 8 to 14 inches thick, and king-size beds should measure at least 10 inches thick. To accommodate a king-size bed frame, your bedroom should be at least 12 feet by 12 feet.

There are larger beds available, but they are not necessary unless you need extra space or sleep with more than one person.

The Saatva Classic is our top recommendation for a high-quality king-size mattress. This luxury innerspring mattress relieves achy backs and joints while providing comfort in any position.

What Is The Most Common Mattress Thickness?

Mattress thickness is not standardized.

Most high-quality mattresses are 8 to 14 inches thick.

According to our classification of mattress thickness, mattresses fall into 5 general categories:

• Low Profile (2-5 inches): These can be found in a variety of configurations including blow-up air beds and space-saving folding floor mattresses. This type of bed is ideal for fitting into a spacious, modern bedroom, or simply for people who prefer a bed closer to the ground.
• Thin (5-8 inches): The slimmest conventional mattresses tend to be made of foam, as it's the densest material. These are budget-priced mattresses, and they often recall the nightmares of guest beds or campsites.
• Standard (8-12 inches): This is one of the most popular sizes/heights of beds because they tend to fall within a mid-price range. Due to lower shipping costs for the seller, the prices are also driven lower for the consumer, since this is a common height that can easily be packaged and vacuum-rolled for shipping.
• Tall (12-16 inches): These are generally the best quality products and are widely available online and in showrooms.
• Extra Tall (16-20 inches): They are a legacy of a time when technological advancements, materials, and construction methods were less sophisticated. The proportions of the bed bases and traditional bedroom furniture work well together in a country retreat setting.

Is There A Bed Bigger Than A King?

There are 4 main "oversized" options, including:

• The Texas king, also known as a super king, measures 80 inches by 98 inches.
• The Wyoming king measures 84 inches by 84.
• The Alberta king measures 96 inches by 96 inches.
• The Alaskan king measures 108 inches by 108 inches.

Note: There is no need to buy any of these oversized mattresses unless you want extra space or sleep with more than 1 person (extra big family, etc.).

How High Should A King Mattress Be Off The Ground?

Bed frames should be 15 to 23 inches off the ground.

As a rule, mattresses should reach the human thigh, and a base's overall height includes both the laying material and the iron frame.

Factors Determining King-Sized Mattress Thickness

A mattress' depth depends on the thickness of its layers.

Most mattresses have two layers, but a high-quality mattress may have three, four, or more.
