FAQs About King-Size Beds

Before you begin shopping for a new king-size bed, come armed with numbers. While king mattresses and frames come in standard sizes, sometimes king-size beds aren’t quite so standard. This guide to king-size bed dimensions has answers to many frequently asked questions about king-size bed dimensions and comparisons with other bed sizes.

What are the dimensions of a king-size bed?

A standard king-size bed measures 76 inches wide by 80 inches long. Measuring one full size larger than a queen-size bed, a king-size bed is the largest standard bed size. While king-size beds are difficult to move and may not fit in every bedroom depending on your room and furniture size, they are the perfect choice for couples looking to maximize individual sleeping space. 

How wide is a king bed? (And why it matters)

Measuring 4 inches wider than a California King-size bed and 16 inches wider than a Queen-size bed, a standard king-size bed is the widest bed standard bed size. 

How big is a king-size bed frame?

While king-size bed frames have the same range of measurements as king bed dimensions, they can vary in overall size due to thickness, material-used, and design. 

What are the dimensions of a king mattress?

King size mattresses can have measurements that are +- 2-3 inches different than standard king-size bed dimensions. Like king bed frames, king mattress dimensions depend heavily on the material used. In terms of mattress depth, king size mattresses usually measure 10-16+ inches thick. 

What are the dimensions of a king headboard?

While standard king-size headboards measure approximately 79-81 inches wide, non-standard king-size headboards can be much wider. In terms of height, king-size headboards range from 48 inches to 64 inches high.

How much bigger is a queen bed than a king?

A king bed is 16 inches wider than a queen bed, although both a standard king and standard queen bed share the same length. For more about queen size beds, check out this guide to Queen bed dimensions.

What is the difference between a king and a California King?

California king beds are slightly more narrow than a standard king—also referred to as Eastern king—beds. A typical king bed measures 76 inches across, but a California King measures just 72 inches across. If you and your partner move around in your sleep, you may want to opt for a typical king bed. If you and your partner are tall, you may prefer the extra four inches of length that a California King provides. 

Does a king and a California king have different bedding?

Standard King and California King beds do not use the same bedding. Although you can find bedding for king beds almost anywhere, it’s harder to find it for California king beds. For this reason, when purchasing a new California King Bed, it may be wise to purchase bedding from the retailer at the same time.
