Nice and fluffy!  These awesome pillows filled my euro pillow cases with no issues. I bought the 28" by 28" to fill 26" by 26" cases.  More than likely could have purchased the same size as my cases since they are so fluffy. Nonetheless, I love them and can't wait until my 3rd one shows up so I can finish up our bed. We use them as decorative pillows and for sitting up in bed to read.
