There are several factors to consider when deciding on the best mattress size, including bedroom size, shopping budget, and the number of people who plan to sleep on the bed. Most mattresses sold today are available in six standard sizes: Twin, Twin Extra Long (XL), Full/Double, Queen, King, and California King. Additionally, select brands and models offer specialty and custom sizes.
This guide will compare the Twin XL and Full/Double sizes. To start, let’s look at the basic differences between these two sizes.
|Size||Twin Extra Long (XL)||Full/Double|
|Standard Width||38″ (3 1/6′)||54″ (4 1/2′)|
|Standard Length||80″ (6 2/3′)||75″ (6 1/4′)|
|Ideal Bedroom Size||Minimum: 7 1/6′ x 10 2/3′||Minimum: 8 1/2′ x 10 1/4′|
|Average Price||$500 to $750||$550 to $800|
|Ideal Sleeping Arrangement||Single sleepers who are too tall for a standard Full/Double, but do not require extra sleeping space in terms of mattress width.||Single sleeper who is average height and prefers some extra sleeping space.|
A Twin Extra Long, or Twin XL, measures eighty inches (80″) long, which is five inches (5″) longer than a standard Twin and Full/Double; both a Twin and Twin XL measure roughly thirty-eight inches (38″) wide. The Twin XL is equivalent to one-half of a standard King-size mattress (76W” x 80L”), and is ideal for sleepers who are too tall for a standard Twin-size mattress. However, the Twin XL is usually too narrow to accommodate more than one person.
Benefits of a Twin XL mattress include the following:
Some drawbacks of a Twin XL mattress include the following:
Also known as a Double, the Full-size mattress measures fifty-four inches (54″) wide by seventy-five inches (75″) long. The Full/Double is ideal for individual sleepers who require a wider sleeping space. For this reason, Full/Double beds are often used in hotels and motels, college dorms, healthcare facilities, and other commercial establishments. Like the Twin XL, Full/Doubles are typically not suitable for couples.
Benefits of a Full/Double mattress include the following:
Drawbacks of Full/Double mattresses include the following:
When comparing the Twin XL and Full/Double sizes, here are a few important questions to keep in mind:
The choice between Twin XL and Full/Double mattresses is essentially a trade-off. The Twin XL is a slightly longer option that is suitable for anyone who stands at 6’7″ or shorer, while the Full/Double offers a more expansive sleep surface that is sixteen inches (16″) wider. Prices are usually negotiable between the two sizes, and neither one will usually cost more than $800. Neither the Twin XL nor the Full/Double are intended for use by more than one sleeper, though — in a pinch — both can accommodate two sleepers with very limited sleeping space.
It’s important to note that these findings are largely subjective. If you are unsure which size will work best for you, we recommend testing both the Twin XL and Full/Double sizes in brick-and-mortar mattress stores. In addition, mattress sleep trials allow you to sleep on both sizes in the comfort of your own home for prolonged periods of time. Simply return the size you are least satisfied with before that sleep trial ends.
