The main difference between a Queen and a King mattress is in their dimensions: while being both 80 inches in length, King measures 78 inches wide, which is 18 inches more than a 60-inch wide Queen mattress.

But the question is:

Does this impact the comfort levels? And if so, how exactly? 

That’s what we’re about to find out in this detailed Queen vs King size comparison!

The Similarities Between King and Queen Sizes

The Similarities Between King and Queen Sizes

Except for the same length, King and Queen mattresses have one more thing in common.

Both of these sizes were introduced to the market by the same company, Simmons, and were launched in the late ’50s (some sources mention 1958).

The appearance of larger mattresses on the market had two causes:

First, with the growth of wealth, people in the Post-War economy started to buy larger houses, and the industry responded by making larger beds that will look better in larger bedrooms. 

Second, due to improved quality of life, the Americans started to gain weight, so they needed more space to move around during sleep. Thus, a larger bed was an obvious step to a more comfortable shut-eye (1).

Now, let’s take a look at the differences between Queen and King. 

Recommended Room Space

Obviously, beds of different sizes need different amounts of room space to comfortably fit in and allow enough space for other furniture as well.

A Queen mattress, which measures 60” x 80”, can fit most standard bedrooms that are at least 10 x 10 feet (2). It takes 33.3 sq.ft of space, which is roughly one-third of the whole area, and allows you to arrange other furniture pieces around the bed without making the room look cramped.

Speaking of a King mattress, it measures 78” x 80”, which is equal to 42.2 sq.ft. If you plan to place a King bed in a standard 10 x 10 master bedroom, it will take almost half of the space.

Given the fact that you also need other pieces of furniture and at least 2 feet of space around the bed to ensure you’ll move freely, the standard bedroom won’t be enough for a mattress this big. That’s why King mattresses are recommended for larger bedrooms, starting at 12 x 12 feet.

Comfort Level

While both King and Queen mattresses can accommodate two average-weight adults, the level of comfort may differ.

A King mattress offers 39 inches of space per person, while Queen offers 30

Also, if you share a bed with a partner and one of you loves to sprawl across the bed or is a heavy sleeper, the other one might feel squashed or cramped on a Queen bed. But King will allow you both to make yourselves comfortable on your own half of the bed.

“King mattresses also come in split options. This allows you and your partner to choose the preferred firmness level and purchase two independent Twin XL halves instead of a one-piece mattress.”

Now, it’s important that you understand that a Queen mattress can also comfortably accommodate two adults. Even heavier sleepers may enjoy it. So, eventually, it comes down to how much space per person you want to have.

Also, note that if you have a kid or a large dog that sometimes wants to sleep with you, King is surely more suited for that.

Market Demand

Market Demand

Not a crucial but still interesting difference between King vs Queen sizes is that they have a different market demand.

In fact, the popularity of Queen skyrocketed after the launch, and it remains the most popular mattress size due today.

According to 2018 statistics, 41.4% of the mattresses shipped in the US were Queens. Kings, on the other hand, had only 17.8% of the market share (3).

But what does high market demand mean, you might ask?

Well, first of all, it’s stable mattress prices. There are many mattress brands out there, and a high market demand means high competition for the client’s attention between them, which keeps them from raising the prices.

Second of all, you’ll more easily find cheaper bedding and accessories for a Queen bed than you’d do for a King one. Most brands in the sleep niche have Queen sheets, mattress toppers, or other sleep products of the Queen size in their line-up. With the King size, you might have to put a bit more effort to find the desired product. 


Finally, the last difference between these two mattresses sizes is the price. 

The Queen size typically has the best value for money. And due to its overall popularity, you can find a decent Queen mattress in any price category, starting at $150 and up to high-end models with a $1,200-1,500 price tag.

What you should know about King mattresses is that they’re usually the most expensive.

Mainly, it’s because King beds require more resources to be manufactured. Generally, the difference between Queen and King mattresses of the same brand will be in the range of $50 to $400, depending on the price category of the mattress.
