Will you mount inside or outside the window casing?
CHECK THE CASING DEPTH. If less than 2”, an outside mount is required.
CHECK THE SQUARENESS. Measure the window casing diagonally in two
places. If the two diagonal dimensions are not equal, we recommend an outside
mount application for optimal function and aesthetics.
Inside mount: Measure height at left, middle,
and right of window. Write down the longest
measurement (round down to an even 1/8").
Outside mount: Measure the exact height of the
window from top edge of molding to bottom edge or
to top of sill if there is one. You may adjust the
length to your preference.
MEASURING the right way for window treatments
Inside mount: Measure width at top, middle,
and bottom of window. Write down the
narrowest measurement (round down to an
Outside mount: Measure to the outside edges
of the molding, then add 4” to ensure light control
STEP 3: MEASURE THE HEIGHT OF THE WINDOW
STEP 1: DETERMINE THE TYPE OF TREATMENT INSTALLATION
Record exact measurements. We will take allowances to get the best fit. Always record in the same order: width x height x depth.
Consider your window operating hardware (handles and cranks) when measuring and considering product selection.

STEP 2: MEASURE THE WIDTH OF THE WINDOW
• Always use a steel tape measure. Do not use cloth tape measure as it may stretch.
• For Inside Mounts, don’t make any deductions—We will take a 1/2” deduction for clearance. Record the actual width and height of the window casing opening.
STEP 4: PLACE YOUR ORDER
Online: Record your window measurements. For inside mount blinds, order blinds the width of your window – we’ll take the necessary deductions.
For outside mount blinds, order blinds 4 inches wider than your window opening.
