How to measure Roller/Solar Shades

Inside Mount

Inside mount shadess are installed inside the window casing. Minimum depth requirements vary by product; please check the product page for information.Inside Mount Image

  1. Measure the exact inside width, to the closest 1/8th inch, of the window casing from the left inside edge to the right inside edge at the top, middle and bottom of the window. Record the narrowest measurement as this will be your ordering width.
  2. Measure the exact inside height, to the closest 1/8th inch, of the window casing from the top inside edge to the bottom inside edge at the left, middle and right side of the window. Record the longest measurement as this will be your ordering height.
  3. Do not make any deductions on width for clearance; the manufacturing facility will make any necessary deductions to ensure the shade fits.
  4. Measure the window diagonally from the top left corner to the bottom right corner, and the top right corner to the bottom left corner. If the measurements are different by more than a 1/4" (inch), we recommend an outside mount installation for optimal fit and aesthetics.
  5. Fabric width will be 1" - 1 5/8" narrower than ordered width depening on the lift option chosen.

Outside Mount

Outside mount shades are installed outside the window casing, covering an area larger than the window opening itself.Outside Mount

  1. Measure the exact width to be covered to the closest 1/8th inch. Make sure the measurement overlaps the window opening by at least 1 1/2" on each side (3" total overlap) to ensure light control and privacy. Typically measured from the left outer edge of the window molding to the right outer edge. Please contact us if you have questions.
    • For solar shade please ensure an overlap of at least 2" on each side (4" total overlap) for ideal light control.
  2. Measure exact height to be covered, including desired overlap (typically from top edge of molding to bottom edge, or to top of sill if there is one). Make sure you consider the height of the headrail/cassette, which is included in the height measurement. If you are installing above the measured area, add the height of the cassette of your shade.
  3. The factory makes no deductions on outside mount shades.
  4. Please note on all roller/solar shades the fabric will be 1 1/2" - 1 5/8" shorter than the ordered width. The ordered width is the widest point of the shade which is from pin end to clutch end of the shade or the left edge to the right edge of the valance. Please add any necessary measurements to your width.

Options

Corner Windows

cornerwindowrlrslr
  • No charge
  • Made as individual shades
  • Each shade will have its own control; we recommend opposite corners
  • Indicate for each shade whether left or right and butt or bypass
  • Bypass shade is mounted into the corner; butt shade is butted to the other shade
  • Manufacturer will take appropriate deductions for proper fit; DO NOT order as a Corner shade if you do not want manufacturer to take deductions
  • Valances will create larger gap between shades
meausurerlrslr Measuring InformationMounting on a Wall or Molding:
Measure the width of each window from the corner on the mounting surface (molding or wall) to the point you would like to cover.
mountrlrslr Mounting Above the Molding:
Measure the width of each window from the corner on the mounting surface to the point you would like to cover.
Projection measurement is the distance needed to clear any molding or obstructions that the shade will be mounted above.NOTE: The Projection (P) distance is needed to correctly calculate deductions for installations where the shades will use shims or projection brackets to clear molding. All projection distances must match for correct deductions to be calculated.

Bay Windows

  • No charge
  • Made as individual shades
  • Each section will have its own control
  • Manufacturer will take appropriate deductions for proper fit; DO NOT order as a Corner shade if you do not want manufacturer to take deductions
  • Valances will create a larger gap between shades

 

Measuring Information: Three-sided Bay Window

Measure:
L and R: Width of each side window from the corners on the mounting surface to the point you would like to cover.
C1: Width of the center window on the mounting surface from corner to corner.
Angle L-C1: Angle between the (L) and (C1) windows.
Angle C1-R:Angle between the (C1) and (R) windows.
Projection: If needed: The depth of the trim or molding the shade will be mounted above.

Measuring Information: Four-sided Bay Window

foursidedbaywndw
Measure:
L and R: Width of each side window from the corners on the mounting surface to the point you would like to cover.
C1, C2: Width of the center window on the mounting surface from corner to corner.
Angle L-C1: Angle between the (L) and (C1) windows.
Angle C1-C2: Angle between the (C1) and (C2) windows.
Angle C2-R: Angle between the (C2) and (R) windows.
Projection: If needed: The depth of the trim or molding the shade will be mounted above.

NOTE:The Projection (P) distance is needed to correctly calculate deductions for installations where the shades will use shims or projection brackets to clear trim or molding. All projection distances must match for correct deductions to be calculated.For additional windows on bays with up to five sides, continue with number progression for center shade sizes (C1, C2, C3, …) and angles (Angle C1-C2, Angle C2-C3, …) as needed. Measure each bay angle using a protractor or angle finder or use two business cards in each bay corner as illustrated above and fax to customer service.
The angle to use between adjacent center bay windows along a straight section of wall is 180 degrees.
