A:AnswerGood Afternoon. Our BEDGEAR Performance Pillows sizes 0.0, 1.0, 2.0, and 3.0 reflect the amount of loft, or height that they provide, with 0.0 being the least amount of loft and 3.0 being the most amount of loft. If you are unsure of what size you should select, we have a "Find your fit" tool on our website, www.BEDGEAR.com, which our customers find helpful in being able to select an appropriate pillow. You may also email "[email protected]", if you would like a Customer Experience Representative to personally fit you for your BEDGEAR Performance Pillow.
