Measure the inside width at the top of the window where the cornice is to be installed - measure in multiple spots to ensure accuracy. If there are any size variations, then use the smallest measurement - this is your ordering width. We will take a small deduction form ordering width to ensure a proper fit (approx 1/4").
Note: Inside mount cornices do not come with returns.
Measure the width of the area you wish to cover. If space allows we recommend adding 2-3" (1-1/2" each side) to this measurement to help eliminate light seepage. This is your ordering width.
Note: This will be the "inside " width of the cornice - the overall width of the cornice will be 1 1/2" wider due to thickness of returns.
Example: A cornice ordered as an "outside mount", 36" wide will be made as 37 1/2" overall.
