A queen size mattress is a popular bed size that measures 60 inches wide by 80 inches long. It provides ample space for couples or individuals who enjoy extra room while sleeping. This size is larger than a full size mattress but smaller than a king size mattress, making it a versatile choice for various bedroom sizes. Queen size bedding typically includes sheets, comforters, and blankets specifically designed to fit this mattress dimension. Many people prefer queen size beds for their balance of comfort and space, making them suitable for both master bedrooms and guest rooms.
