Things to Consider Before Deciding Between King Size vs Twin Size Mattress

Apart from your personal preferences, many factors need to be considered picking one mattress size. We’ve compiled a list of factors you should consider while choosing between king vs. queen bed size. 

Room Size

A king-size bed requires a room measuring 13 feet by 13 feet (up to 13 feet by 19 feet), while a queen-size bed requires a room measuring 10 feet by 10 feet (up to 10 by 14 feet). 

Generally, leaving 2 feet on each side of the bed and 5 feet at the bed’s base provides you additional space to walk around the room. If you go for a queen-size bed for a big-sized room or master bedroom, you’ll have enough space to fit in additional furniture. However, choosing a king size bed for a small room may be the bigger problem as the room may feel cramped. 

Sleeping Partner

Single adults and couples prefer a queen bed as it gives them ample space to sprawl. Most couples would be happy sharing a queen, but those who need more space should think of upgrading to a king size mattress. Couples who share a bed with children or pets should opt for a king to ensure enough space.


A queen and a king size mattress are the same lengths making them both great options for individuals taller than 6 feet 2 inches. Very tall sleepers may look into the California king as it is longer than king or queen bed sizes. 

Generally, there’s a difference of around two to a few hundred dollars in price between a queen bed vs. king bed – the king bed being the more expensive one.  

Both these mattresses are readily available. But the additional bedding accessories like bed frames, adjustable base, allied bedding items, etc., for a king bed could be more expensive than a queen. So,  if you’re on a tight budget queen bed could be a better option. 

Bed Size

Depending on the brand you choose, a king size mattress needs a bed that is 76 inches by 80 inches. Anything smaller than that will make using the whole bed a problem as the mattress will hang from the sides. 

A queen size mattress needs a bed that is 60.5 wide and 80 inches long. Do check the model and the structure of your bed before you make the final decision.
