How Thick Is a Queen Mattress?

Standard Queen Dimensions

• The standard dimensions of a queen mattress are 60 inches wide by 80 inches long. To compare this with other mattress dimensions, a standard full mattress measures approximately 53 inches by 75 inches, while the standard king-sized mattress measures 76 inches by 80 inches. These constitute approximate measurements, as each mattress manufacturer upholsters its mattresses differently, which leads to a discrepancy of a few inches.

Thicknesses Measurements

• Thickness measurements on mattresses vary wildly and often come under designations other than thickness, such as height. Some thicknesses of queen-sized mattresses commercially available in the Untied States as of 2011 are 6.75 inches, 8 inches (described by one mattress manufacturer as "traditional"), 10.75 inches, 11 inches, 12 inches, 13 inches, 13.5 inches and 15 inches. These measurements consider solely the mattress, not the box spring or other support upon which the mattress sits.

Thickness Considerations

• Various considerations affect the thickness of a mattress. Mattresses designed to conform to the body, such as memory foam mattresses, generally have larger thickness measurements than regular mattresses. Discount mattresses and others designed for easy portability are relatively thin. Other factors affecting thickness include quilting, layering, manufacturing method and quilting.

Additional Information

• Mattress thickness relates to the brand and type of the mattress, but not necessarily to the size. Some memory foam mattresses, for instance, fall into types and each type has the same height across all sizes. Some companies allow consumers to customize mattresses by choosing accoutrements such as foam and quilting, which affect thickness by adding additional layers.
