Buckwheat Hull Pillow Size Preference?

[StratCat48]

Considering a buckwheat hull pillow. Traditionally since our bed is queen sized, I've typically bought queen size pillows. Of the buckwheat pillows I've looked at, 15"x20" or so seems common and weigh about 4-5 pounds. A larger queen size is up to about 10 pounds I think and I am also thinking it may be a bit on the heavy side to move around for comfort if needed. Is there any opinion on size for buckwheat pillows that a smaller (15"x20") is a size that one can get use to coming from a larger pillow?
Besides size anything else to consider (already looking at cases with zippers to add or remove fill)?

I like the smaller size. Since I use a nasal mask, I hang my nose over the end of the pillow. I’m a side sleeper.

Be careful where you buy it. 
Go to the Pinetales web site. There is a wealth of information there. It’s a must read before buying a buckwheat pillow. 

I have the regular size, it’s plenty big and very moldable. And, yes, plan to remove some of the buckwheat. It’s my pillow of choice.

I use a 14" x 20" buckwheat pillow from Amazon. Works well for me. I used to use a standard size "regular" pillow.

Per my experience, it isn't the size that is critical, it's the loft (height). Thankfully, you can adjust the height by removing a portion of the filling. I now alternate between a buckwheat pillow and a MyPillow -- both with filling removed to provide a 2-inch height which works best for me.
