Full vs. Double Bed Mattress- The Difference

Full vs Double Bed

When choosing the right bed size, factors like comfort, space, and sleeping habits play a crucial role. The decision between a full bed vs. double bed often confuses buyers due to their similar dimensions.

In this comprehensive guide, we’ll break down the differences between these two bed sizes, helping you make an informed decision for a good night’s sleep.

What is a Full Mattress?

A full bed, also known as a double bed, offers more space than a twin bed but is smaller than a queen bed. It typically measures 54 inches in width and 75 inches in length.

This size suits single sleepers who enjoy extra room to stretch out. Couples who prefer to sleep close together might find a full bed too snug.

Pros & Cons of Full-Size Mattresses


  • Ideal for single sleepers: The full bed offers ample space for individuals to move around comfortably.
  • Fits smaller rooms: Its compact size makes it an excellent choice for bedrooms with limited space.
  • Cost-effective: Full beds are often more affordable than more extensive options like queen or king.
  • Cozy feel: The snug dimensions can provide comfort and security.


  • Limited space for couples: Sharing a full bed with a partner might feel cramped, especially for those who prefer more room.

What is a Double Bed?

The term double bed can be confusing, as it’s used interchangeably with the full bed size in some regions. However, in some contexts, a double bed might refer to a slightly more prominent option, measuring around 54 inches in width.

This size provides a bit more space for single sleepers and can accommodate couples who don’t mind sleeping closer together.

Pros & Cons of Double Size Mattresses


  • More space for single sleepers: The larger double bed variant offers added comfort for individuals.
  • Couples’ compatibility: Double beds can be suitable for couples who prefer sleeping close together.
  • Versatility: It balances space-saving and comfort, making it versatile for various room sizes.


  • Space constraints: While more significant than a standard full bed, the double bed might still feel tight for couples who want more personal space.
  • Room size matters: Placing a double bed in a small room could make the space feel overcrowded.

Factors to Consider Before Choosing Full vs. Double Bed

When deciding between a full bed and a double bed, consider these factors:


Choosing between a full bed and a double bed involves considering factors like space, sleeping habits, and personal preferences. While both options have merits, the decision ultimately concerns what suits your lifestyle and comfort needs.

Whether you prioritize extra room to stretch out or a cozy sleeping environment, understanding the distinctions between these bed sizes will guide you toward a restful night’s sleep.


Are Full and Double Beds the Same?

The size of a double bed and a full-size mattress are both 54 inches by 75 inches. People use “double bed” and “full-size mattress” interchangeably. The terms “double” and “full” relate to mattress sizes and are identical.

Can a Double Bed Accommodate Two Adults?

A full mattress, also called a double bed, has long been considered the best size for a bed for two people or adults. However, some couples may find that a queen or king-size mattress is the best choice.

Is a Full Bed Suitable for a Guest Room?

Full beds work best in places about 10 feet by 12 feet, like guest rooms or bedrooms. If your room is smaller than that, you might want to get a twin-size bed instead. The best size for a bedroom with a queen bed is 12 feet by 12 feet, but anything over 10 feet by 10 feet should work.
