How to Measure



  •  Measure the width of the window opening or outside mounted window trim that the cornice will be mounted over. Add at least two inches to the width measured to be sure of allowing sufficient clearances.
  • The top of an outside mounted cornice will need to be mounted approximately 1 1/2 inches above the window opening or existing window trim.
  • When installing over an outside mounted window treatment, order the returns at least 1 inch greater than the "flush mount depth" of your under-treatment. Returns can be ordered from 3 inches to 8 inches in 1/8 inch increments.


  • Crown cornices are 7 inches wider on the outside at the top than the inside width ordered. Be certain you have room to accommodate this width.
