What Are the Dimensions of a Queen Size Mattress

Choosing the right mattress starts with understanding its size. If you’re shopping for a new bed, you’ve probably asked: what are the dimensions of a queen size mattress? A queen mattress is one of the most popular mattress sizes worldwide because it strikes the perfect balance between comfort and space efficiency. It offers ample sleeping room for couples while fitting comfortably in most bedrooms. In this guide, we’ll break down the exact queen size mattress dimensions, explain how they compare to other mattress sizes, and help you determine whether a queen mattress is the right choice for your sleeping needs and room layout.

Dimensions of a Queen Size Mattress

A standard queen size mattress measures:

• Width: 60 inches (152 cm)

• Length: 80 inches (203 cm)

This size provides enough space for two adults to sleep comfortably without taking up excessive room space. Each sleeper gets approximately 30 inches of personal width, which is similar to having an individual twin mattress side by side.

Queen mattresses are widely available, making it easy to find compatible bed frames, sheets, and accessories. Because of their versatility, they are commonly used in master bedrooms, guest rooms, and apartments.

Standard Queen Size Mattress Dimensions

While the surface dimensions of a queen mattress remain consistent, the thickness (or height) can vary significantly depending on mattress type and construction.

Standard queen mattress dimensions:

• Width: 60 inches

• Length: 80 inches

• Thickness: 8 to 14 inches (can go up to 16 inches for luxury models)

Common mattress thickness options:

• 8–10 inches: Budget or guest room mattresses

• 10–12 inches: Most common, suitable for all sleepers

• 12–14+ inches: Premium hybrid or pillow-top mattresses

Thicker mattresses often provide better pressure relief, motion isolation, and durability, but they may require deep-pocket sheets and compatible bed frames.
