Small Single 30″ x 75″ – good for babies and small children.
Twin 38″ wide x 75″ long – this is suitable for larger kids, teenagers and single adults in small apartments. Mattress of this size are often used for bunk beds in ships, barracks, dorms and guest rooms. For kids, there are no mattress sizes smaller except for small single. What parents need to consider is that when their children grow older, they’ll need to move them to larger rooms or beds, replace Small Single mattresses with Twin as Twin mattresses are made more comfortable. Comfort is paramount as people get older.
Twin XL 38” wide x 80”long – there are single kids and adults that are larger and taller than usual and these bed sizes should accommodate them perfectly.
Full 54” wide x 75” long – also known as standard double, this is great for single toss-sleeping adults who require plenty of leg room, for single parents with children or singles who sleep with pets, or for couples who don’t require much legroom or sleep in small quarters.
Full XL 54” wide x 80” long – same as the above but with extra leg room for taller individuals or couples. This is for individuals who like to live large. Often the choice for hotels that accommodate couples.
Queen 60”wide x 80”long – This is already excessive for single persons but perfect for most couples. This is often the choice for couples that don’t require much sleep space, sleep in smaller rooms and/or have no plans accommodating kids or pets in the short run.
Olympic Queen 66” x 80” – Slightly wider than King Size. Good for couples with smaller kids or a pet in between. This bed type is also more suited for square rooms while the former is suited for rectangular rooms.
King Size 76”wide x 80”long Also known as Eastern King, this is a quite substantial bed for couples with enough space for both to sleep comfortably and can accommodate a third person, often a child. This is a pretty large bed recommended only for rooms with a minimum dimension of 12’ x 12’. King size is also recommended for couples with different mattress preferences (firmer or softer). A King size bed can accommodate two Twin XL mattresses in case the partners’ tastes differ. Waking up from a good night’s sleep can be seen as a factor in relationships.
California King 72”wide x 84”long Also known as Western King, this type of bed is slightly longer and narrower than the standard King size. This bed is suitable for taller sleepers. Considering room dimensions, this bed would be perfect for longer and narrower rooms. One caveat of this type of bed is that it’s harder to accessorize with sheets and mattresses.
