Standard measuring procedures apply to blinds that fit rectangular
windows. For tricky windows and uncommon applications please review our specialty guide. Before you begin we recommend printing out and using our
Measuring Worksheet when measuring for your blinds.

Window Blinds & Shades 1) Measure the width inside the window opening at the top, middle and bottom. Take the narrowest of the three width measurements, and round down to the nearest 1/8". 2) Measure the height inside the window opening from the top of the window opening to the window sill three times. Measure once on the left, at the center, and on the right and take the longest of the three measurements. If you prefer to keep the blind from resting on the sill deduct a 1/4" from the height. If your window does not have a sill, measure to the point you would like the blind to reach. 3) Measure the window on the diagonal. If the two diagonal dimensions differ significantly, it may be necessary to order an outside mount for optimal light control and privacy. See measuring instructions below. 4) Do not take any allowances on the height or width. The factory will take all required allowances on an inside mount for mounting and operating clearance. |

Vertical Blinds 1) Measure the width inside the window opening at the top, and round down to the nearest 1/8" measurement. 2) Measure the height inside the window opening from the top of the window opening to the window sill three times. Measure once on the left, at the center, and on the right and take the shortest of the three measurements , and round down to the nearest 1/8" measurement. 3) Do not take any allowances on the height or width. The factory will take all required allowances on an inside mount for mounting and operating clearance. |

Roller / Solar Shades 1) Measure the width inside the window opening at the top, and round down to the nearest 1/8" measurement . 2) Measure the height inside the window opening from the top of the window opening to the window sill. If your window does not have a sill, measure to the point you would like the blind to reach. 3) Do not take any allowances on the height or width. The factory will take all required allowances on an inside mount. 4) Because the factory takes deductions on the fabric width some windows may have visible light gaps visible on the left and right edge. To eliminate light gaps and for increased privacy it may be necessary to order an outside mount. See measuring instructions below. |

Window Blinds & Shades 1) Measure the distance from the outermost points you would like the blind to cover. To minimize light leakage the blind should overlap the window opening by at least 1 1/2" on each side for a total of 3" on entire width. 2) Measure distance from where the top of the blind will be located to the window sill. The blind should overlap the window opening on the top by at least 1-1/2". Some products may require more then 1-1/2" above the window for mounting hardware. Please review product specifications on desired product for exact flat vertical surface area requirements. If flat vertical surface area exceeds 1-1/2" use specified amount to determine overlap above the window opening. If there is no window sill, measure to the point you would like the blind to reach. |

Vertical Blinds 1) Measure the distance from the outermost points you would like the blind to cover. To minimize light leakage and ensure privacy the blind should overlap the window opening by 4" on each side for a total of 8" on entire width. 2) Measure distance from where the top of the blind will be located to the window sill. The blind should overlap the window opening on the top and the bottom by at least 3". 3) If the blind will hang to the floor, take a 1/2" deduction on the height to allow for operating clearance. |

Vertical Blinds for Patio Door 1) Measure the distance from the outermost points you would like the blind to cover. To minimize light leakage and ensure privacy the blind should overlap the window opening by 4" on each side for a total of 8" on entire width. 2) Consider the size of the vertical blind stack. Allow sufficient overlap for easy access through the door. 3) Measure distance from where the top of the blind will be located to the floor on the left side, center, and right side of the window. The blind should overlap the window opening on the top by at least 3". 4) Take a 1/2" deduction on the height to allow for operating clearance. |

Roller / Solar Shades 1) Tip-to-tip: Measure the distance from the outer most points you would like the headrail to extend. Depending on the product, the fabric width will be up to 1-3/8" narrower then the tip-to-tip measurement provided. The exact amount of fabric deduct can be obtained by contacting customer service. To minimize light leakage the blind should overlap the window opening by at least 2" on each side for a total of 4" on entire width. 2) Fabric width: Measure the distance from the outer most point you would like to fabric to extend. Add the outside mount fabric deduct to this measurement (typically 1-1/8" to 1-3/8"). The exact amount can be obtained by contacting customer service to determine fabric deducts on outside mount applications. 3) Measure distance from where the top of the blind will be located to the window sill. The blind should overlap the window opening on the top by at least 1-1/2". Some products maybe require more then 1-1/2" above the window for mounting hardware. Please review product specifications on desired product for exact flat vertical surface area requirements. If flat vertical surface area exceeds 1-1/2" use specified amount to determine overlap above the window opening. If there is no window sill, measure to the point you would like the blind to reach. |
