Buying a bed is a big decision because your sleeping habits and overall health are all on the line. With so many size options and confusing terminology, it can be challenging to navigate the process of choosing the perfect bed. But, if you are wondering how big is a king-size bed we've already done the research, so you can rest assured you buy the right size mattress.
A standard king-size mattress is 76 inches wide and 80 inches long. When measuring space for a king-size bed, consider the height and length of the bed frame, additional height of a box spring or mattress topper, and the height and width of the headboard and footboard. Depending on the style you prefer, king mattresses do range in size, from 72 inches to 108 inches wide and 78 inches to 108 inches long - so you can select the right fit for your frame style and room configuration.
Keep reading, and we'll discuss the various styles of king-size mattresses and compare these to other, standard bed sizes. We'll also share how to measure your bed to size for any room and how to make your bed look and feel larger.
How Wide is a King-Size Bed?
A standard king-size bed is 76 inches wide (or 6 feet, 4 inches). For comparison, a standard queen-size mattress is approximately 60 inches wide and 80 inches long. These dimensions mean that a king-size mattress has around 20% more sleeping area than a queen-size mattress. And, compared to a twin bed, the king has 100% more sleeping area.
Whether you share your bed with children or pets, or if you and your partner prefer plenty of personal space to stretch out, a king-size bed offers by far the most spacious width mattress you can find.
How Long Is A King-Size Bed?
Interestingly, measuring at 80 inches (or 6 feet, 8 inches) long, a standard king-size mattress is the same length as a queen-size mattress. Either would be comfortable for taller sleepers.
Full-size beds and twin beds, in comparison, are usually 75 inches long, which means that anyone over 6 feet tall would likely feel cramped and uncomfortable.
What Is The Size Of A King-Size Bed In Feet?
A standard king-size bed measures 6 feet, 4 inches wide by 6 feet, 8 inches long.
For planning purposes, keep in mind that beds are usually larger than mattresses because of the additional frame, headboard, and footboard. Be sure to factor in the mattress size, plus a few extra inches when you try to determine if a bed will fit in your space.
How Tall Is A King Size Bed?
In terms of height, king-size mattresses can range from 5 inches to 20 inches tall, depending on the mattress type. King-size bed frames also vary widely in their heights, depending on the style you prefer.
If you prefer a low bed, you can either choose a short bed frame (some barely lift the mattress off the floor) or a thinner king mattress to keep your sleeping surface low to the ground.

If you prefer a high bed, choose either a taller bed frame or a thicker king mattress. Investing in a king-size box spring or mattress topper can also increase the height at which you sleep.

Can A King Bed Fit In A 10x10 Foot Room?
A standard king-size mattress is only 6 feet, 4 inches by 6 feet, 8 inches, so it can certainly fit in a 10x10 foot room.
Larger types of king-size beds, such as the Alaska King, might not fit as well. Even though the 9 feet by 9 feet Alaska King can technically fit in a 10x10 ft room, you might have trouble moving around the bed or even opening the bedroom or closet door!
It is also essential to consider the extra space that a bedframe will take up. Depending on the frame you choose, you might end up feeling like the bed is too big. Be sure to account for a bedframe and not just a mattress in any measurements you make.

How Can I Make My Bed Bigger than a King-Size?
One option for a larger than king-size is to purchase a larger type of king-size mattress. The Alaskan King, Wyoming King, and Grand King mattresses are all larger than the standard king-size.
California King is an option if you want a longer bed, but you don't mind a narrower width.
If you would like to add height to your bed and make it appear bigger, you can choose a thicker mattress or purchase a box spring and mattress pad.
