Sleep Experts Discuss Mattress Sizes

What to Consider When Choosing a Queen or King Mattress


Starting with the dimensions of both designs, we have the King size, which is 76 inches by 80 inches. This is perfect for master bedrooms and couples since it provides more than enough space per person.

On the flipside, you’ll need to have large enough room for it. You don’t want a King bed overpowering a small room, and you’d have to account for other furniture in the space like a dresser and nightstand.

Queen mattresses measure 60 inches by 80 inches. The main difference between these two is the width. However, 16 inches is substantial. Queen models are appropriate for couples who don’t have the luxury of a large master room and need something more compact and space-efficient.

A King mattress is usually more expensive than a Queen. This stems from the larger dimensions of the bed. The same goes for its accessories.

Purchasing a set for a King bed will cost you more than getting one for a Queen. That said, the difference is not so substantial that you should completely rule out one or the other. Plus, both sizes are popular, which provides you with a large breathing room to search for cheaper accessories.


The comfort of both sizes would depend on whether you’d be sleeping alone or with a partner. Do you love an extravagantly big bed you can roll around on and feel you have enough space, even with a partner on it? Then a King would be best since these give you an extra 16 inches of width to sleep on.


Even though the Queen is far more popular than the King, both are wildly distributed, so finding accessories for them should be easy. Every specialized store you walk into should provide you with a range of options for your Queen or King-size mattress.

Additionally, as we mentioned above, the pricing is not significantly different, and you can find affordable solutions for both sizes.

Room Size

This is also something you would have to account for. While every couple is likely to enjoy the additional 16 inches of width on the King, not each one of them would be able to allow the additional room space.

Both Queen and King beds should fit well into rooms measuring 12 feet by 12 feet. That said, some people may prefer to have even more space if they’re getting a King-size mattress. In this case, something that’s 12 feet by 14 feet, for example, might be preferred.


If you and your partner prefer more space, consider a King-size bed, which is 16 inches wider. King mattresses are also a great choice for larger-bodied partners. When shopping for a King mattress, couples should expect that the bed and its accessories will cost more than a Queen.  

Queen are the most popular mattress choice, and these beds are generally less expensive than King-size mattresses. This can be helpful for couples on a budget. Queen-size options are also good for couples who don’t have a larger bedroom or who don’t need the extra width. 

In the event you or your partner is significantly taller, though, then we’d recommend going with a California King mattress, which is 4 inches longer than a standard King.

What’s the difference between a Full and Queen mattress?

With a Queen, you’ll have 60 inches of width and 80 inches of length. Fulls provide 54 inches of width and 75 inches of length. A Full mattress is going to be the better choice for someone who sleeps alone, while a Queen would be better for a couple. There are some couples who might have to utilize a Full bed to accommodate their bedroom size, but the surface space of a Full mattress won’t give you much room to spread out.

Which is better, a King or Queen bed?

Both King and Queen beds have their advantages, so it really comes down to how much space you have in your bedroom, and whether or not you’re sharing the bed. For those with less bedroom space and who are either sleeping alone or don’t mind sleeping closer to their partner, a Queen is a great choice. 

However, if you’re sharing the bed and want to be able to spread out, and you have the bedroom space to accommodate a King, we recommend going for the larger bed size. This way you and your partner will have plenty of space to sleep comfortably without disturbing each other.

Do most couples have a King or Queen bed?

Most couples in the U.S. have Queen beds. These can be a great choice for people who don’t have enough space for the larger King bed or who want to spend a bit less on their bed and bedding. 

How much longer is a King mattress than a Queen?

King and Queen mattresses are both 80 inches in length. The difference is in their width: King mattresses are 76 inches wide, whereas Queens are 60 inches wide. 

Final Word of Advice

Of course, the size difference between a Queen and King mattress is substantial. The extra 16 inches of width can make a big change, but a larger bed also means you need more space for it. With this said, the choice is ultimately yours. Consider your personal preferences as well as the ones of your sleeping partner if you have one.
