Queen vs King
Quick answer
King wins for couples. A King is 76 inches wide against Queen's 60 inches, which works out to 38 inches of width per sleeper on a King versus 30 inches per sleeper on a Queen, a meaningfully bigger personal footprint for two adults sharing a bed nightly. Queen wins for solo sleepers, guest rooms and smaller bedrooms, where King's extra 16 inches of width will not leave comfortable walking clearance on both sides, and where Queen's lower cost and wider selection of frames and bedding matter more than extra width nobody is using.
Queen and King are the two most commonly sold mattress sizes in the country, and most bedrooms could physically fit either one. The decision usually comes down to two things: how many people are sleeping in the bed, and how much floor space is left over once the mattress and its frame are in the room. Both are covered below with the actual numbers rather than a vague "it depends."

How much does 16 extra inches of width really change for two sleepers?
Queen and King are the same 80 inch length, so the entire difference between them is width, and all 16 of those inches go to whoever is sharing the bed. Split evenly, a Queen gives each of two sleepers 30 inches, close to the width of a child's twin bed cut in half. A King gives each sleeper 38 inches, which is enough that a restless partner is less likely to disturb the other side of the bed.
The tradeoff is footprint. A King needs roughly 16 more inches of room width than a Queen to sit in the same spot, plus the walking clearance on both sides. Run your exact room dimensions through Room Size and Clearance Calculator before assuming a King will fit: a bedroom that comfortably clears a Queen with 30 inches on each side can drop to a tight 22 inches per side once a King goes in, which is below the 24 inch minimum most people find workable to walk past.
Cost scales with the size, too. A King mattress, King frame, King sheets and a King comforter all cost more than the same items in Queen, since more material goes into every one of them. That difference is worth weighing against the per-sleeper width gain, especially for a household that is budget-conscious or furnishing more than one bedroom at once.
Who should actually pick each one?
Pick King if you regularly share the bed with a partner and want real distance between you at night, your bedroom has the extra width to spare with comfortable clearance on both sides, or you simply move around a lot in your sleep and keep waking each other up on a smaller size.
Pick Queen if you sleep alone, the bed is for a guest room where floor space matters more than maximum width, your bedroom is on the smaller side and a King would eat the walking clearance, or you want the wider selection and typically lower prices that come with Queen being the single most common size sold.
A useful middle test: measure the narrowest path from your bedroom door to the far wall. If a King leaves less than about 24 inches of clearance on either side once it is in place, Queen is very likely the better fit for that specific room regardless of how many people sleep in it.

Frequently asked questions
How much wider is a King than a Queen?
A King is 76 inches wide and a Queen is 60 inches wide, a difference of exactly 16 inches. Both sizes share the same 80 inch length, so that entire 16 inch difference goes to width. Split between two sleepers, that works out to 38 inches of personal space each on a King versus 30 inches each on a Queen.
Do I need a bigger bedroom for a King than a Queen?
Yes, roughly 16 more inches of width plus the walking clearance on both sides, since a King and Queen share the same length. As a guideline, allow at least 24 inches on each side of the bed to walk past comfortably, more if you want room for nightstands or to open dresser drawers. Run your exact room dimensions through a bed-room-size calculator before buying.
Is King or Queen better for a solo sleeper?
Queen, in almost every case. A solo sleeper does not need the extra width a King provides, and Queen mattresses, frames and bedding are generally less expensive and more widely available since Queen is the most commonly sold size. A King's extra floor footprint also eats into a bedroom's walking clearance with no real benefit for one person.
Do Queen and King mattresses use the same sheets?
No. Queen is 60 by 80 inches and King is 76 by 80 inches, a 16 inch difference in width, so a fitted sheet sized for one will not fit the other's mattress properly. The two also generally need different bed frames, since a frame's rails are built to the exact mattress footprint it is designed for.
Is a King mattress always better than a Queen?
Not for every household. King wins on personal space for two sleepers, but it costs more, needs a larger bedroom to keep comfortable walking clearance, and its extra width is wasted on a solo sleeper or a guest room. Queen remains the better choice whenever floor space, budget or a single sleeper make the extra width unnecessary.
How to read the numbers on this page. Standard mattress and bedding dimensions are industry-wide and the same across manufacturers. Guidance like replacement intervals, firmness by body weight and walking clearance is convention rather than a measured standard, and every table here says which it is. Where a manufacturer does not publish a figure we leave it out instead of estimating. This is not medical advice: a mattress is not a treatment for a medical condition, and persistent pain is a reason to see a clinician.
