What do your pillow dimensions mean?

Bed pillow dimensions are listed "on the flat", meaning before they are filled.  Once fill is added (turning a 2D shape into 3D) the sides effectively "pull in" as they accommodate that extra dimension.  Lightly stuffed will pull sides in less than a pillow super stuffed.  Because of this variation, the on-the-flat dimension is the way the measurements are standardized across the industry.  Although the loft (i.e. fill amount) of our pillows can be increased or decreased with our Adjustable Loft Feature, please keep this 2D-to-3D "shrinking" in mind when ordering in case you want to go up a size.
