A king-size mattress is the most common mattress used in almost every household. It fits well in a master bedroom or a room larger than 12×12 feet. This is the most convenient investment for couples who prefer sharing their beds with children or pets. A standard king-sized bed is 80 inches long and 76 inches wide which is the same dimension as two twin XL-sized mattresses placed side by side.

How To Choose Between King-Sized and Split King-Sized Mattresses

It is tough to find the difference between a split king mattress and a king mattress, but one must analyze the specifications and needs while choosing the mattress. If you choose king-sized mattresses, then the room should at least be 14×19 feet to accommodate the bed and other furniture. While in a split king mattress, the same dimensions are needed if using both beds in the same room. But if used as two twin XL beds, these can easily fit in smaller rooms.

Both king-size and split king kind mattresses provide couples ample space for cuddling. The only difference is a split king mattress provides individual needs of a partner. King-sized and split king mattresses are ideal for master bedrooms.

Apart from the king and split king sizes, two more sizes can be considered, whether you are a single or a couple. They are the Full size and the Queen Size mattress. They also have the standard size and are also budgeting-friendly.

In comparison, the queen-sized mattresses are ideal for couples sleeping without children providing enough space for tall people. If your mind questions the full vs queen dimensions, they are 56 inches wide X 75 inches long and 60 inches wide X 80 inches long.
