Arches (Outside Mount)

• First, decide where you'd like to mount the blind outside the window frame. You'll need at least 1" of flat surface. You can mount it below the window opening, just remember to add height the lower you go. For more details, check the "Specifications" tab on the product page.

Standard Arch

Measuring the Width

• Measure only the window opening.
  
  
• To determine the width, measure from left to right at the bottom of the arch.
  
  
• You’ll use that measurement and add the recommended minimum of 4 inches. For example, if the window opening is 32", it would be helpful to order 36". This will provide 2" of coverage on each side of the window for maximum privacy and light gap coverage.
  
  
• You can order narrower or wider based on your application, but the above example is a typical addition.
  
  
• This is the width you will use when ordering.

Measuring the Height

• Measure only the window opening.
  
  
• To determine the height, divide your width in half and measure the height at that location.
  
  
• Make a minimum addition to the size of 4". For example, if the window height is 32", it would be helpful to order 36" This will provide enough overlap for maximum privacy.
  
  
• You can order taller or shorter based on your application, but the above example is a typical addition.
  
  
• This is the height you will use when ordering.

Quarter Arches

Measuring the Width

• Only measure inside the window opening.
  
  
• To determine the width, measure from left to right at the bottom of the quarter arch.
  
  
• Round down to the nearest 1/8” if you are receiving a measurement in 16^ths or 32^nds.
  
  
• Use this width measurement when ordering.

Measuring the Height

• Measure only the window opening.
  
  
• To determine the height, measure at the left or right side of your window (depending on whether it is a left or right facing quarter arch). This should be the tallest portion of your window.
  
  
• Round down to the nearest 1/8” if you are receiving a measurement in 16^ths or 32^nds.
  
  
• This is the height measurement you will use when ordering.
