A King mattress measures 76 x 80 inches, while a Queen mattress measures 60 x 80 inches. Both are 80 inches long, but a King is 16 inches wider than a Queen, giving couples more space to sleep. The added width can also be useful for parents who co-sleep with children. A Queen takes up less floor space, making it easier to fit in a smaller bedroom.

Here's how King and Queen mattresses compare in terms of sleeping space, room space, bedding, price, bed frames, and overall versatility.
A Queen size bed gives two adults 30 inches of space each. That's enough for most couples. A standard King bed gives each sleeper 38 inches of space, which is 8 more than a Queen. This can make a big difference if you like more personal space or share the bed with a child.
Since both sizes have the same length, choosing a King won't give you additional legroom. Taller sleepers who need more length should consider a California King mattress.
A Queen mattress needs less floor space than a King. A 10 x 10 feet room is the minimum recommended bedroom size for a Queen, while a 12 x 12 feet room is recommended for a King. A Queen would be the better choice if a King size mattress leaves your room feeling crowded.
Before buying, measure your bedroom with existing furniture in place. Leave enough space to walk around the bed comfortably.
Queen and King mattresses need different fitted sheets and mattress protectors, since King is much wider. Flat sheets and comforters are more flexible and may still work if you don't mind less coverage. But for fitted bedding, always consider the mattress dimensions and pocket depth before buying.
Queen mattresses are more budget-friendly than King, which is part of why they're the most popular size in the US. Entry-level models range from $600 to $1,500, and premium models range from $1,300 to $2,200.
King mattresses are a costly investment. Entry-level models range from $800 to $2,000, and premium models range from $1,600 to $2,800. But with the extra cost comes the extra size.
Your budget should continue beyond the mattress. Bed frames, fitted sheets, mattress protectors, and other bedding all add to the total cost of a good night's sleep.
A Queen bed frame measures 62 to 65 inches wide and 82 to 85 inches long, while a King size bed frame is around 78 to 81 inches wide and 82 to 85 inches long. A Queen frame won't fit a King mattress, so you'll need the right size frame if you're upgrading from Queen to King.
Bed frames are slightly wider and longer than mattresses to accommodate internal structural supports, thick side rails, headboards, and bedding layers.
Queen mattresses can support around 500 to 600 pounds, while King mattresses can handle 600 to 700 pounds. For heavyweight couples, a King is better long-term, as it'll support more weight and provide more space for your bodies.

Queen and King mattresses are both really common, so finding mattresses in either size is easy. Most stores also carry a wide range of Queen/King size bed frames and bedding.
The right size comes down to how many people will use the bed, how much room you have, and how much sleeping space you want.
A Queen is more practical for single sleepers. It gives you plenty of room to stretch out without using as much bedroom space or sapping up too much of your budget. A King makes more sense if you want a very large sleep surface and have a bedroom big enough to handle it.
A Queen works well for average couples. Each person gets about 30 inches of width. A King, on the other hand, gives about 38 inches per person, which is great for partners who like having their own little corner in the bed.
A King is ideal if your child or pet regularly sleeps with you. Two adults can fit on a Queen, but adding another sleeper leaves less room for everyone. The extra 16 inches of width a King provides gives the bed more usable space for co-sleeping.
Queen is a good fit for most guest rooms. It gives two adults enough sleeping space without taking up as much of the room. A King is more suitable for a master guest room where couples appreciate extra space.

If you're deciding between the two, think about how you'll use the mattress over the next several years. A Queen gives couples enough space while using less bedroom floor area. A King provides 16 additional inches of width, which can be valuable for couples who want more room and for families who share the bed. If you need extra length rather than width, a California King bed (72 x 84 inches) could also be a better fit.
