Next review our detailed measuring guide. In our measuring guide you will find instructions on how to measure most typical windows for both inside and outside mount. For tricky windows and uncommon applications please review our specialty guide.

Inside Mount (IB) - 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.

Inside Mount (IB) - 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.

Inside Mount (IB) - 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.

Outside Mount (OB) - 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.

Outside Mount (OB) - 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.

Outside Mount (OB) - 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.

Outside Mount (OB) - Roller 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.

Outside Mount - French Doors

1) Start your measurement a minimum of 2" above the glass (3" recommended) and measure down 2" below the glass. This will provide enough room to mount installation brackets at the top and hold down brackets at the bottom. The extra height above your window will also allow the blind to stack up above the glass and provide a less obstructed view.

2) Measure the width of the glass and at a minimum of 1" (2" recommended) to both sides of the glass. The door handle may constrain the maximum amount of overlap that can be added to the width.

Specialty - Cut-Outs aka Tile Cut-Outs

A cut-out is a rectangular area removed from a blind or shade to avoid obstruction. This cut-out is normally from one of the corners or from the bottom. A tile back splash or window air conditioner are two common examples of obstructions that may benefit from a cut-out.

Cut-outs are an additional charge. Not all products allow cut-outs. Please contact our customer service team to determine if the product you are interested in allows cut outs.

1) Measure your window normally for an inside or outside mount. This will give you the overall width and overall height.

2) Next measure the required cut-in from the side of the shade followed but the cut-out height.

3) In addition, mark your measurements on a sketch of the cut-out to ensure the order is processed correctly.

Specialty - Bay Windows

A bay window is a series of windows with at least three sides that projects from the exterior wall of a house.

1) First determine the depth of the product you are mounting and use this for the width of your poster board. You can obtain this depth on blind product pages or through customer service at 1-877-388-0336 .

2) Next cut out two pieces of poster board the width of the product depth by 12" long. If extra clearance necessitates the use of extension brackets or spacer blocks, include this extra clearance to the width dimension of the poster board.

3) Place the strips you have cut as shown below. By placing strip "A" in the left angle first and bring together strip in "A" and "B" until the front corners of the poster board meet you will obtain the correct angle. Mark points "A" and "B". Repeat for strips "C" and "D".

4) Measure from the left corner of "B" to the right corner of "C" to obtain the width measurement of the center window treatment. Measure from from the right corner of "A" outward to the desired width to obtain the width measurement of the left window treatment. Measure from left corner of "D" outward to the desired width to obtain the width measurement of the right window treatment.

5) Height of the window treatments is determined in the normal horizontal blind fashion.

Specialty - Corner Windows

Butt and Bypass Shades

With two windows which meet in a corner, two shades butt against each other. One shade is the "butt" shade and the other is the "bypass" shade as shown in the left diagram.

1) Measure each shade separately using normal horizontal blind procedures described here.

2) Once completed simply subtract headrail depth from the butt shade to obtain the proper ordering width.

3) With outside mounted shades allow for overlap on the sides and the bottom.

4) For specific headrail depth refer to blind product pages or call customer service at 1-877-388-0336 .

Corner Windows not using Butt and Bypass

Some window fashions such as soft verticals cannot use the Butt and Bypass. They are then measured to meet in the corner.

1) Begin by measuring the width of both openings to the common corner.

2) Now deduct the necessary depth of the treatment from the width of each measurement so they will meet in the corner but not overlap.

3) If the use of spacer blocks or extension brackets is necessary for extra clearance on outside mounts, add the amount of extra clearance to the deduction.

4) Order the width less the deduction for each window.

Windows with Molding or Trim

Outside Mount

1) Measure from the far left edge of the trim to the far right edge of the trim

2) For wood blinds, faux wood blinds, aluminum blinds, and other products with end mount brackets take a 1/4" deduction from the measurement to allow room to mount the end brackets onto the trim.

3) To expose some of the trim, measure the window opening and then add the amount of trim you would like covered to each side of the window opening size.

4) To expose all of your trim measure the window opening.

5) Measure the height from the top edge of the window trim to the bottom edge of the window trim or the window sill. To mount the blind above the window trim start your measurement at least 2" above the top edge of the trim and measure down to the bottom edge of the window trim or window sill.

Inside Mount

Make sure your window has enough depth to mount the product you will be ordering. If the window has sufficient depth, follow standard inside mount measuring instructions found in our measuring guide.
