So I have ALWAYS slept with a standard size pillow and I like that size. I ordered the KING size to give it a try and it works well, but I have had to adjust how I hold the pillow at night because it is so much larger than what I was used to. I am a side sleeper and it is long enough to lay my head on and also cuddle with to help keep my body in a nice supported position. I like that it is machine washable and I would like to order the standard size. I think the standard size is my preference because that is what I have always known, but this is a great pillow if you like a larger pillow.
