King Size Bed vs Queen: Mattress Size

Deciding on the king size bed vs queen size depends on the number of individuals sleeping on the bed, your budget, and the room size. The king size is spacious and allows for a couple and a child or pet to sleep on it. The queen size bed’s narrower width allows for only two adults to sleep on it. However, a king mattress is usually heavy and harder to move around, which can be a problem in apartments or smaller spaces. You can look into getting a mattress in a box for easy movement and a quick setup - the size doesn’t matter with these unique mattresses.

Best for Couples, couple & child, couple & pet Couples, single adults, three children together
Room Size  Large master bedrooms or open plan spaces Guest rooms, medium-sized master bedrooms, apartments

Recommended Room Size

Is your room spacious enough for a king size bed? An important point that you may forget when buying a mattress is having enough room space for it. Before buying a mattress or a bed frame, you need to take your room’s measurements and know where the bed will be placed. Placing a king size bed in a small bedroom will cram the room and completely restrict your movement. It is recommended to leave at least 2 feet on all sides surrounding the bed to move around easily and in case you’re putting a bedside table or other furniture pieces near the bed.

The recommended room size for a queen size bed is 10 by 10 feet while the room size for a king size bed should be 12 by 12 feet. A queen size bed will comfortably fit in both spaces but may be too big for smaller bedrooms.

Bed Size

Before buying a mattress, you need to make sure it’s the same size as your bed. Don’t just estimate measurements and hope for the best, take your bed’s dimensions to get a mattress that’s a perfect fit. If your mattress is bigger than your bed frame and you try to press it in place, it will damage the mattress. Alternatively, if your mattress is smaller than your bed size, there will be a gap between the mattress and bed frame. This will lead to lumps and your mattress will prematurely sag.

A mattress is a long-term commitment so you don’t want to ruin your new mattress by mistakenly buying the wrong size.
