There's something, about having a spacious king size bed in your bedroom turning it into a cozy retreat for peaceful sleep. Personally I've found that enjoying the width of a king size bed has really improved the quality of my rest. Looking into the specifics of a king size bed I've learned that the standard width is 76 inches and it typically measures 76 inches by 80 inches, in total. The dimensions translate to around 6.3 by 6.7 feet offering space for a comfortable sleeping experience.
