Notes: How to measure: Pull tight along the outer seams, and measure the middle of your sham, from seam to seam, height, and width, to see what size inserts are needed. Recommended: These pillow inserts are recommended for decor sham pillows, for your couch or sofa. Decoration: For best results, your pillow inserts should be larger than your sham to correctly fill the corners of the pillow cover, This will provide a very attractive firm, and fluffy look to your sham. We recommend placing our inserts in shams that are 1" to 2" smaller than the pillow, It would depend on the thickness of the sham, a thick fabric would need a 2" larger insert to keep it fluffed, and a thinner fabric would need a 1" lager insert.

Note this is an extremely flat, low, and thin pillow.
