Premium Fabric-Wrapped Cornices
Measure Notes:• An inside mount cornice has a depth of
3" (mounting board/dust cover)• Measure depth of window casing to
determine if it will accommodate an inside mount
• Determine inside or outside mount• Face width will be approximately
11⁄2" wider than the ordered width• Inside mount will be approximately
1⁄2" less than the ordered width
Fabric-Wrapped Cornices
Measure Notes:• Determine inside or outside mount • Outside mount face width on the curved
cornice will be approximately 21⁄2" wider than the ordered width
• Outside mount face width on the other fabric-wrapped cornice styles will be 11⁄2" wider than the ordered width
• Inside mount will be approximately 1⁄2" less than the ordered width

Mounting Options
Outside Mount:1. Measure window width including
molding (see figure 1).2. Add any additional width desired,
especially if hanging curtain panels or sheers under cornice (see figure 2). Round up to the nearest full inch.
3. Recommended 2" minimum clearance on face and sides when mounting over a drapery (see figure 3).
4. Recommended 1" when mounting over inside mount treatments.
Inside Mount:1. Measure the exact width of the window
opening at the very top of the casing (see figure 4).
2. Measure the exact width of the window opening down from the top, depending on the desired length of top treatments being ordered.
Tips for getting started:1. Use a steel tape measure. Measure to the nearest 1⁄8".2. Take measurements at the top of window, as not all windows are perfectly square.3. If ordering top treatments for multiple windows, make sure to measure each window individually.
NOTE: Measure twice and document the smaller dimension, as not all window openings are perfectly square.

Bay and Corner Windows
• Available in the linear premium fabric-wrapped cornice• Measure bay angle using protractor or angle finder, or use two business cards in bay corner as illustrated.
• Fabric-wrapped cornices—straight style only• Shown as outside mount, with returns• Outside mount projection = return depth• Inside mount—projection is specified by the customer• Excludes curved cornice
Measure:Left Cornice: Width from corner (B) to the outside
desired width (A).Right Cornice: Width from corner (B) to the outside
desired width (C).Projection/Return Depth (P): Depth from wall to back of cornice.Choose Either: Left butt/right bypass (as shown in image)
or left bypass/right butt.
NOTE: Face of cornice will be approximately 3⁄4" greater than the ordered projection/return measurement.
