The size difference between a queen and king bed is the main component separating the two options.

Meanwhile, standard queen mattresses are 60 inches wide and 80 inches long with a surface area of 4,800 square inches.

Since both sizes are the same length, the real deciding factor between a queen vs. king bed is how wide you’d like your mattress to be.

When deciding between mattress sizes, thinking about comfort is key. If you like to sprawl out under the covers, the larger surface area of king size bedding can provide the space you need. However, those who prefer a snug sleeping arrangement might find queen beds more appealing.

Whether you’re leaning toward a king or queen bed, studies have shown that mattress comfort is directly linked to better sleep quality. That’s why you’ll want to consider which type of mattress will make you the most comfortable.

Other Sleepers

While sleeping beside others might give you a better night’s rest, it can also impact the bed size you choose. Those sharing a mattress with a partner, children, or pets might want the added surface area of a king size bed. That way, no one is likely to feel cramped.

Alternatively, if you don’t mind cuddling up next to your partner or pet all night, you might opt for a smaller queen bed. Being up close and personal with those in your bed can make the extra space of a king size mattress feel unnecessary.

If you love your pets but prefer not to share a mattress with them, you might want to consider gifting them cozy dog beds so they can have snooze-worthy sleep of their own.

Room Size

Depending on your room size, you might prefer a king vs. queen bed. Queen beds are suitable for bedrooms of at least 10 x 10 feet. Worried it might be a tight squeeze? There are all kinds of ways to arrange a small bedroom with a queen bed.

Meanwhile, king beds fit most comfortably in bedrooms that are at least 12 x 12 feet, which is typical for primary bedrooms. The bigger bed can add a statement to a more spacious room, especially if you know how to style a king size bed.

Your Height

Standard king and queen mattresses are both 80 inches (or 6 feet, 8 inches) long, so you might not think height factors into the king vs. queen discussion. However, king beds are available in more than one size.

California king mattress come in at 84 inches (or 7 feet) long. With the added length, a California king makes a great option for taller sleepers.

Another factor to consider is how easy it’ll be to move your mattress. Although most mattress sizes fit comfortably through staircases and door frames, it’s important to take note of the dimensions of your entryways before buying a new bed.

In addition, the added surface area of a king mattress makes it heavier to transport. Lifting heavy objects can lead to low back pain and other injuries. If you live on a top floor or plan to move regularly, choosing a lighter queen mattress might be a better call. For those looking to stay put, a king mattress can be a solid investment.
