Choosing Between Queen and King Size Beds

Choosing Between Queen and King Size Beds

Before you purchase a mattress, think about these factors so that it helps you to choose between a queen mattress and a king mattress.  

Room size 

The size of your room is important in deciding the ideal bed size for you. A queen mattress is best for smaller spaces, with a suggested dimension of at least 10 by 10 feet to provide comfort. A king mattress is best suited for rooms that are at least 12 by 12 feet due to its significantly larger size. Leave 2 to 3 feet of gap between the wall and your bed frame so that you can move freely. 


Budget is also a crucial factor in finding the perfect bed for you. A queen mattress is often less expensive than a king mattress in terms of cost. Prices vary but typically range from $850 to $1,200 for a queen mattress and $1,000 to $1,700 for a king mattress. Your budget will be determined by the manufacturer and type of mattress you purchase.  

Sleeping preferences 

Another crucial factor to consider is how you sleep and whether you share a bed with your partner. The wider design of a king bed may be best suited for you if you move around a lot whereas a queen bed is usually sufficient for people who usually don’t move while they sleep. Your sleeping position also has an impact. As compared to back or stomach sleepers, who stretch out while sleeping and require more space, side sleepers typically curl up when they sleep. 


Choosing the right bed size, whether queen or king, is a decision that requires thoughtful consideration of different factors. Understanding the distinctions between these sizes, like dimensions, features, and misconceptions, is necessary for making a well-informed option based on individual preferences and needs. Whether selecting a queen or king-size bed, understanding the differences and assessing personal needs will lead to an enjoyable and comfortable sleep.
