- Measure each window individually, as sizes may vary from window to window.
- Record measurements in total number of inches (rather than feet and inches) to avoid errors.
- Always use a metal measuring tape or ruler.
- Decide if your blind or shade is to be installed inside or outside the window frame.
- As shown at right, take a measurement in three places horizontally and three places vertically to see if the window is perfectly square.
- If there is too much deviation, outside mount is strongly recommended.
Measuring For Horizontal Mini-Blinds Or Shades
A headrail protects the mechanism that raises and lowers the blind/shade.
For outside/on-casing installation:
This type of installation is most recommended for maximum room darkening effect and optimum privacy.
Measure where the headrail will be installed. Headrail must overlap window by 1 1/2" on each side if molding exists or, where there is no molding, by 3" on each side.
If molding exists, measure from where top of headrail will be installed on the molding. If there is no molding, allow 4" above the window for the headrail. Measure to sill or floor and deduct 1" for clearance.
For inside casing installation:
Casing must be at least 1 1/2" deep to install headrail. Measure the exact distance between the inside of the frame. Take three measurements (top, middle and bottom). Use the smallest measurement.
Measure from inside casing top to bottom.
Remember: Give the exact measurements, the cutting facility will deduct 1/8 to 1/4". Do not take any deductions.
Measuring For Roller Shades
Brackets hold the roller in place.
For new roller shades, measure the window horizontally in three places. Order the smallest width. Remember, the cutting facility will deduct 1/8 to 1/4". Do not take any deductions.
Measuring For Vertical Blinds
A headrail protects the mechanism that operates the vertical blind. We recommend verticals be mounted on the outside casing only.
Outside casing installation:
Measure where headrail will be installed. The headrail must overlap the window or door opening by at least 3" on each side for proper stacking.
Measure from where top of headrail will be installed to sill or floor; subtract 1/2" for clearance.
Measuring For Shutters
Decide whether you prefer your shutters to be hung inside or outside the window frame.
For Traditional shutters, inside installation requires a jamb depth of 1 1/4". Outside installation requires a jamb depth of 3/4".
For Plantation shutters, inside installation requires a jamb depth of 1 1/2". Outside installation requires a jamb depth of 3/4".
Measuring your window
Lay your shutter set down on a flat surface (including hanging strips & E/Z StripsTM). Measure the total width and length of shutter set and compare with window opening.
Inside mount installation
Measure the window width and height in at least 3 different places. Use the narrowest of dimensions. The window opening must be square. If the measurements differ by more than 1/2" we suggest an outside installation.
Outside mount installation
Measure the window width and height in at least 3 different places. Use the widest of dimensions. Peel-away E/Z Stripsª are not used in outside installation and therefore should be removed. The shutter width should be a minimum of 2 1/2" wider than the inside of the window. If your window has a molding some shims may be necessary to create a flat surface for hanging.
