Full XL Mattress Size: The Ultimate Guide

The world of mattress sizes can be a labyrinth of choices. While most are familiar with standard sizes like twin, full, queen, and king, the Full XL remains a bit of a mystery. Dive in as we unravel the intricacies of the Full XL mattress.

Is There a Full XL Mattress?

Indeed, there is! The Full XL mattress is a variation of the full size, offering extra length for those who need more foot space.

What is a Full XL Mattress?

The Full XL mattress, as the name suggests, is an extended version of the full mattress. Designed to provide additional length, it’s ideal for taller individuals who might find the standard full mattress a tad short.

Full XL Mattress Dimensions

To truly grasp the Full XL size, let’s look at its dimensions:

  • Width: Approximately 54 inches
  • Length: Approximately 80 inches
  • Depth: Varies based on the brand and type, but typically ranges from 9 to 12 inches.

How Long is a Full XL Mattress?

A Full XL mattress offers a length of around 80 inches, making it the same length as a queen or king mattress.

How Big is a Full XL Mattress?

In terms of surface area, the Full XL provides an ample space of 54 inches in width by 80 inches in length.

Will a Full XL Mattress Fit on a Full Bed Frame?

Here’s where caution is needed:

  • A Full XL mattress is longer than a standard full mattress.
  • It might not perfectly fit a standard full bed frame without some overhang.
  • It’s recommended to invest in a Full XL bed frame to ensure a proper fit.

Full XL Mattress vs. Full

Comparing the two:

  • Size: The main difference is the length. Both share the same width (54 inches), but the Full XL is longer by about 5 inches.
  • Suitability: The Full XL is more suited for taller individuals, while a standard full can cater to average height sleepers.

Difference Between Full and Full XL Mattress

Elaborating on the distinctions:

  1. Length: The Full XL offers an extra 5 inches in length.
  2. Price: Often, the Full XL comes at a slightly higher price point due to the additional material.
  3. Availability: Full mattresses are more commonly available, while Full XL options might be limited in some stores.

Full XL Mattress Size vs. Queen

How does the Full XL stack up against the queen?

  • Width: The queen mattress is wider by about 6 inches.
  • Length: Both share the same length of 80 inches.
  • Space: A queen mattress offers more space, especially beneficial for couples.


  1. Is the Full XL mattress good for couples? It can be a tight fit. For couples, a queen or king size might be more comfortable.
  2. Where can I buy Full XL beddings? While not as common as standard sizes, many major bedding stores and online platforms offer Full XL beddings.
  3. Is there a significant price difference between Full and Full XL mattresses? Generally, the Full XL is priced slightly higher, but the difference isn’t substantial.


The Full XL mattress, with its unique dimensions, fills a niche in the mattress market. Catering especially to taller individuals who need that extra legroom but don’t necessarily want the width of a queen, it’s a size that deserves more recognition.
