what size is a king size pillow

A king size pillow measures 20 inches by 36 inches. However, it is important to note that pillow sizes may vary slightly depending on the brand. King size pillows are longer than standard pillows and are a convenient option for active sleepers who tend to toss and turn in bed. They can also be used for back support when sitting up in bed to read or watch TV more comfortably. Two king size pillows can fit perfectly across a king-sized bed, and they can also be used on a California king or split king bed.
