When selecting the right mattress size, there are several factors to keep in mind, such as bedroom area, shopping budget, and the number of people who plan to sleep on the mattress. Most mattresses sold today are available in six standard sizes: Twin, Twin Extra Long (XL), Full/Double, Queen, King, and California King. Additionally, some mattress brands offer models in specialty and/or custom sizes.
This guide will compare the two smallest standard mattress sizes, Twin and Twin XL. First, let’s look at the key similarities and differences between these two sizes.
|Size||Twin||Twin Extra Long (XL)|
|Standard Width||38″ (3 1/6′)||38″ (3 1/6′)|
|Standard Length||75″ (6 1/4′)||80″ (6 2/3′)|
|Ideal Bedroom Size||Minimum: 7 1/6′ x 10 1/4′||Minimum: 7 1/6′ x 10 2/3′|
|Average Price||$300 to $600||$500 to $750|
|Ideal Sleeping Arrangement||Single sleepers who do not require extra sleeping space in terms of width and are not taller than 6’2″.||Single sleepers who are too tall for a standard Twin, but do not require extra sleeping space in terms of mattress width.|
A Twin is the smallest standard mattress size available, measuring thirty-eight inches (38″) wide by seventy-five inches (75″) long. This size is commonly found in college dorms, as well as hospitals, nursing homes, and other healthcare facilities with overnight accommodations.
Some drawbacks of a Twin mattress include the following:
A Twin Extra Long, or Twin XL, measures eighty inches (80″) long, which is five inches (5″) longer than a standard Twin; both a Twin and Twin XL measure roughly thirty-eight inches (38″) wide. For reference, a Twin XL is roughly equivalent to one-half of a standard King-size mattress (76W” x 80L”).
Benefits of a Twin XL mattress include the following:
Drawbacks of Twin XL mattresses include the following:
When comparing the Twin and Twin XL sizes, here are a few important questions to keep in mind:
Because Twin and Twin XL mattresses have similar dimensions and tend to have comparable price-points, the decision to choose one over the other often comes down to length. A Twin XL will comfortably accommodate anyone who stands at 6’7″ or shorter, while a Twin will be suitable for anyone who stands 6’2″ or shorter. A Twin-size mattress may be the better option for children who sleep in bunk beds that are too short to accommodate Twin XL mattresses, but if the child is not using a bunk bed then either size will usually suffice. It’s important to note that neither the Twin nor the Twin XL will accommodate most couples, nor do they provide extra width space for single sleepers.
These findings are quite subjective. If you can’t decide which size is right, we suggest testing out Twin and Twin XL mattresses in brick-and-mortar stores to see which length feels best. You can also sleep on both sizes for a prolonged period of time by selecting brands and models with sleep trials. Simply return the mattress that is less satisfactory before the trial period ends in order to receive a full refund.
