Selecting the correct size

  • To ensure you select the correct size pillow form for your sham please keep the following information in mind.
  • The pillow forms you order should be larger than the sham you are using!
  • A common rule of thumb for shams 18x18 and larger is to order a pillow form 2" larger than the sham.  For example a 18"x18" sham should use a 20"x20" pillow form.
  • Shams smaller than 18x18 should use the same size insert or a size 1" larger if a fuller look is desired. 
  • It is NOT necessary to order larger sizes on Bolster Inserts
